Betaine and the Paleo Diet

Betaine is one of the many nutrients found in the body and it offers many ways to help our bodies function better and to look and feel healthier. As such, Betaine is a vital nutrient to consume as part of our diet and there are many foods which contain Betaine and offer numerous other health benefits. Betaine can be found in animals, plants and microorganisms and it is responsible for breaking up the fats and protein in the body. It enables the heart and blood vessels to function more effectively. The other benefit of Betaine is that it helps in treating homocysteine, which is a very harmful amino acid which can be obstructive to our blood vessels and cause strokes.

Homocystinuria is an illness which results from high levels of homocysteine and it can lead to extreme tiredness and fatigue, which is why it is essential to ensure we have the right amount of Betaine in our bodies. One of the other advantages of Betaine in our diets is that it increases the function of our metabolism, so is a good nutrient for promoting weight loss. It reduces fluid in our bodies which can lead to a fluctuation in our weight. It is important to intake the right amount of Betaine and not consume too much or too little of this essential nutrient, as it has the potential to lead to health problems.

Betaine is also thought to reduce the fatty deposits which can occur on the liver, often with alcoholics or those who suffer from illnesses such as diabetes. It is also thought that Betaine works well together with B vitamins so that the body is more protected from outside ailments which can lead to a weakened immune system and low resistance to colds and flus.

Intaking Betaine

On average, humans will consume about 1 gram of Betaine from any standard diet, but this is a lot higher when following the Paleo diet. Betaine can be found in supplements, but it is also found in a variety of foods, which is the most beneficial way of consuming the nutrient. The Paleo diet encourages the consumption of a number of different foods which have a high content of Betaine, such as vegetables which are known to have high levels of Betaine. The two most effective vegetables to eat as a means of raising Betaine levels are beets and spinach, although there are many others which have smaller levels of Betaine.

The main Betaine content of beets is found in the peel and the flesh and there are many ways to introduce it into the diet as part of the Paleo way of living. Beets can be boiled and mixed up with other vegetables to create a really tasty salad. You can also add some apple cider vinegar to create an even more flavoursome salad, while maximising the benefits to your health. Beets are also full of other vitamins and nutrients which act as an antioxidant to improve the immune system and promote a healthier body.

It is also quite simple to add spinach to your meals and this is a great food choice for increasing consumption of Betaine. Spinach is a really tasty addition to a salad or side dish which can be eaten raw or boiled. It also protects against homocysteine which makes it the perfect choice for a healthier diet and lifestyle. Spinach offers numerous other benefits to the health and should be a regular addition to your meals on the Paleo diet.

You can also find Betaine in other food groups which are encouraged as part of the Paleo diet, including fish, such as haddock and trout. A good meal which will keep your Betaine levels high would consist of fish and plenty of vegetables, in particular spinach and beets. You can also add shellfish to your diet if you want an easy alternative to your meals with a good level of Betaine.

The variety of good foods available on the Paleo diet and the fact that it improves Betaine levels further increases the importance of this type of diet. Unlike other diets which are only useful for weight loss and are more like fads rather than a way of life, the Paleo diet offers an important way to change your life positively for the future. There are many ways to incorporate all of the right foods with plenty of nutrients, including Betaine into your meals and these do not need to be complicated to prepare.

Betaine’s Role in Gut Health and Digestive Function

Beyond its benefits for cardiovascular health and metabolism, Betaine also plays a key role in supporting gut function. Specifically, Betaine Hydrochloride (Betaine HCl) is sometimes used in supplementation to increase stomach acid. This is particularly helpful for those who experience symptoms of low stomach acid, such as bloating, indigestion, and nutrient malabsorption. While not everyone on a Paleo diet will require Betaine HCl supplements, the emphasis on whole, unprocessed foods means you're more likely to restore natural digestive function over time — and Betaine can support that journey.

With poor digestion becoming more prevalent due to highly processed foods and chronic stress, consuming Betaine-rich foods can help enhance stomach acid production, ensuring optimal breakdown of proteins and absorption of nutrients like B12, calcium, and iron.

Betaine and Inflammation Reduction

Emerging research suggests that Betaine may help reduce inflammation by acting as a methyl donor in critical biochemical reactions. Chronic low-grade inflammation is believed to be at the root of many modern health issues, including autoimmune conditions, obesity, and metabolic syndrome. By improving methylation — a fundamental process for detoxification, gene regulation, and neurotransmitter balance — Betaine can help the body manage inflammation more efficiently.

Following a Paleo diet, which already limits inflammatory triggers such as refined grains and processed seed oils, means your body is in a better position to utilise nutrients like Betaine effectively. Add that to its role in liver health and detoxification, and it becomes clear that Betaine is an underappreciated but essential nutrient.

Other Paleo Foods Rich in Betaine

While beets and spinach are standout sources of Betaine, there are several other Paleo-friendly foods you can rotate into your meals to maintain optimal levels:

Quinoa (if tolerated): Though not technically Paleo for everyone, some individuals following a modified approach include quinoa. It’s one of the richest plant sources of Betaine.
Sweet potatoes: These starchy vegetables provide Betaine and also support gut health with their fibre content.
Turkey: A lean protein that contributes modest levels of Betaine while also being rich in essential amino acids.
Amaranth: Another pseudo-grain, occasionally incorporated by more flexible Paleo eaters for its high Betaine and protein profile.
Shellfish: Mussels, clams, and oysters contain a variety of minerals alongside Betaine, making them a perfect addition to your weekly meal plan.

The key to benefiting from Betaine is variety. Regularly including leafy greens, root vegetables, quality seafood, and animal proteins will ensure you’re not missing out.

Signs You Might Need More Betaine

If you’re struggling with low energy, sluggish digestion, or have a family history of cardiovascular disease, you might benefit from increasing your Betaine intake. While blood testing is the only way to confirm elevated homocysteine, symptoms such as frequent fatigue, memory issues, or poor recovery after exercise can be indicators that your methylation cycle is underperforming — something Betaine directly supports.

Digestive discomfort, bloating after high-protein meals, or a general sense of heaviness can also be signs that your stomach acid is too low. In these cases, focusing on Betaine-rich foods (and potentially Betaine HCl under professional guidance) may be worth exploring.

Simple Paleo Meal Ideas to Maximise Betaine

Here are a few meal ideas to help you incorporate more Betaine-rich foods into your diet, without complicating your routine:

Roasted beet and walnut salad: Serve with grilled chicken and a simple apple cider vinaigrette for a nutrient-packed lunch.
Pan-fried trout with sautéed spinach: A quick weeknight dinner that covers both protein and greens.
Shellfish stew: Combine mussels, garlic, sweet potato, celery, and herbs in a light broth for a warming, Betaine-rich meal.
Green smoothie: Blend spinach, beetroot, cucumber, lemon juice, and a small piece of ginger for a refreshing start to your day.
Egg and veggie hash: Cook up a medley of beets, sweet potato, and spinach with eggs for a hearty Paleo breakfast.

Conclusion: Is Betaine the Missing Link?

While not often discussed outside of scientific circles, Betaine plays a quietly powerful role in health and vitality. Its impact on liver function, cardiovascular health, methylation, and digestion makes it an unsung hero of optimal wellness. Fortunately, a properly constructed Paleo diet — rich in vegetables, quality proteins, and healthy fats — provides ample opportunity to keep your Betaine levels where they should be.

Rather than turning to supplements as a first step, prioritise your meals. Incorporate Betaine-rich ingredients regularly, and observe how your energy, digestion, and resilience improve. If you’ve experienced any noticeable benefits from eating more beets, spinach, or seafood, share your experience in the comments below — it’s always great to hear how real food is making a real difference.

Do you get enough Betaine in your diet?

Can You Get Enough Calcium On A Paleo Diet?

3 Comments

If you've told anyone you follow a Paleo diet, one of the typical responses you’ve probably got back, is bound to be “but how can you get enough Calcium?”

As part of any healthy lifestyle it is essential to have a decent amount of calcium in the diet, as it is involved in so many crucial functions. Calcium is known to strengthen the bones and teeth and can help to reduce the risk of suffering from osteoporosis, which causes brittle bones and can be very detrimental in the quality of life for sufferers. It is also thought the mineral can help to prevent cardiovascular disease and other illnesses which can cause a lot of problems in later life.

In order to really get the benefits from calcium, it is important to incorporate it with other nutrients and vitamins, as they work in conjunction with each other to produce the most effective results. Vitamins such as C and D3 help the body to absorb calcium so that the benefits are maximised. If these vitamins are not present in the diet, it won’t be absorbed sufficiently, which means the calcium won’t offer the benefits you would expect from it.

We don’t all require the same intake of calcium; there are factors which affect the level of calcium we should consume in our diet. Children require a lower level than adults and women are usually required to take in more calcium than men. Pregnant women should also try to take in a higher level of calcium as it will be beneficial for both mother and baby.

We know that calcium is essential for the body, but we have been led to believe that we need a lot more in our diet than what we actually need. It is also a misconception that the only way we can get the calcium we need is through the consumption of dairy products and in particular milk, which is not the case. There are many other foods which provide a good quantity of calcium and more than enough to ensure we have an adequate amount in our bodies. It can also be detrimental if we consume too much calcium, as it inhibits the absorption of magnesium. Magnesium is important for a healthy body and a lack of this can have an adverse effect on the body.

As a strict Paleo diet excludes dairy, many people wrongly assume eating this way will result in a Calcium deficiency. However, this simply is not the case. Not only are there some far better sources than milk – when the processed foods are removed from your diet your calcium requirements are actually lower. In fact, it is not calcium intake that is important, rather calcium balance. Processed things such as soft drinks actually use calcium in their digestion – effectively leeching calcium from your body. If you eat a lot of these types of foods, your calcium requirements are clearly going to be a lot higher. When you eat a natural Paleo diet – real food – your requirements are going to be a lot less.

Good Paleo Calcium Sources

There are lots of foods other than dairy products which many people just don’t associate with calcium. These foods act as a good source of calcium and provide us with other health benefits, including providing an adequate amounts of essential vitamins and other minerals.

Leafy green vegetables are a great calcium sources, as are high quantity of fish, such as salmon and mackerel. These can also offer a substantial amount of the mineral, as well as providing us with vitamins and antioxidants which are the perfect way of maintaining a healthy lifestyle.

Walnuts and hazelnuts are other foods which act as a good source of calcium. It is important not to eat too many of these though due to the Omega 3/6 ratio, so sticking to a low quantity will achieve the desired result. Eggs are also a way of ensuring calcium is present in the body and in particular egg yolks are a good source. It is a good idea to take note of the calcium levels of the foods you are eating, so you know whether you are taking in too much or too little.

CoQ10 & The Paleo Diet

2 Comments

Yet another possible deficiency is Co Enzyme Q10 (CoQ10), even on a strict Paleo diet.

What is CoQ10?

It actually assists with mitochondrial electron transfer and stress reactions that happen biochemically within the body. You cannot have too much Co Enzyme Q10, as it is great for providing better nutrient density to the mitochondria to help us make and burn more energy. It also helps increase our exercise ability and stamina.

Exercising helps increase the oxidation that occurs from our stress hormones with most exercise hermetic when things are in balance and running smoothly. If we are suffering from a co Enzyme Q10 deficiency caused by statins, Neolithic diseases or from just generally being unfit and out of shape there is a need to increase the dietary intake of Co Enzyme Q10 to optimise health.

CoQ10 comes in two forms, Ubiquinone and Ubiquinol, with one being an oxidised form and the other a reduced form – you can tell which is which by the price! Ubiquinol is three times more expensive because it is much harder to make the reduced optimal form. Ubiquinol contains two hydroxyl groups rather than just one; this allows it to bond much better with water molecules making it more readily absorbable by the mitochondria in our cells to help with energy production.

Primal Diet Supplement Vitamin Mineral Deficiency

Ubiquinol is also the biologically superior form of Co Enzyme Q10 because it is an electron donor; this makes it a very effective neutraliser of free radicals. It is the only form of Co Enzyme Q10 that looks for lipid peroxyl radicals that can cause damage to the polyunsaturated fatty acids present in your cell membranes. When you are eating a Paleo diet this is a wonderful benefit as depletion of cellular Co Enzyme Q10 can’t support basic cellular functions. A Paleo diet together with a higher activity level requires optimal cellular and mitochondrial functions.

At the 5^th Annual International CoQ10 symposium that was held in Kobe, Japan findings were released that showed the superiority of ubiquinol when given to a group of seriously ill patients with advanced stage cardiac disorders. If this can help those who are close to death with severe heart failure it is a critical component for any person looking to change their life by adopting a new healthy living plan or diet.

The study revealed that those clinically ill patients who had already suffered from heart failure easily absorbed ubiquinol CoE10 into their bloodstream showing excellent improvements in all heath parameters. Another key factor that was announced was those with Hashimoto’s or other autoimmune diseases really need to only use the ubiquinol as they are unable to convert ubiquinone into ubiquinol due to their low B12 and B6 levels. They also need higher doses of ubiquinol more often.

Estrogen & The Paleo Diet

6 Comments

When people mention estrogen they are more often than not referring to estradiol which is the major form of oestrogen in both men and premenopausal women. Today we will talk about estradiol which is the hormone that has the most wide-ranging effects on both women and men.

What is estrogen?

It’s actually a catch-all type term for a number of chemicals with similar functions and shapes such as estradiol (E2) or estrone (E3). During a female's reproductive years her estradiol levels are higher than other estrogens. During menopause however these estradiol levels decrease with the bulk of the woman’s estrogen content coming from E3 and E1. This is important as it is the E2 that the woman’s ovaries pump out and this is what has the biggest effect on her reproducing years – sending fat stores to the hips and thighs rather than to the abdomen. It is the decrease in E2 during menopause that leads to an increase of abdominal fat.

Estrogen is also responsible for maturing the female sex organs and the growth of the uterus. In males while testosterone is responsible for the male reproductive organs estrogens inhibits the death of cells in sperm cells.

Estrogen actually inhibits growth and has been used effectively to stop girls growing too tall. It is also a major part of bone development for males and females and can lead to poor bone density as women age as they become unable to produce normal amounts of estrogen. Estrogen replacement therapy usually assists and rectifies the bone density problem.

Women suffering from clinical depression have been found to produce less estrogen – but more testosterone, than normal with estrogen replacement therapy helping their condition. Men who suffer from depression actually produce far more estrogen than normal. Women also have an increase in function of their atherosclerotic arteries which could help explain the increase in heart conditions in pre-menopausal women.

Estrogen has reduced the formation of amyloid plaque that occurs in the brain of Alzheimer patients. In as many as 80% of breast cancer cases estrogen receptor sites rely on estrogen for fuel, with a rather common treatment for this type of breast cancer being to suppress the production of estrogen. Research has shown that males who received high levels of estrogen whilst in the womb are at greater risk of developing prostate and testicular cancer as adults.

Estrogen is very useful and can reduce strength and lean muscle mass while still promoting body fat accumulation with estrogen-dominant males often being obese and under-muscled. It is the large dose of estrogen that throws off the delicate hormonal balance and cause problems. While stunting a Child's growth might sound negative when you first hear about it, unchecked growth can have terrible consequences for the Child's health.

Both males and females need and produce estrogen for a reason as it has some very important uses within the human body. The problems lie in the unnatural amounts of the hormone within the body . Estrogen is essential for both women and men but imbalances – especially in post-menopausal women and in men can lead to muscle loss and fat gain.

Have you had your levels tested? If you've had an imbalance, please share your experience in the comments below – you never know who you might help out!

How Modern Diets Influence Estrogen Levels

Modern Western diets, with their high levels of processed foods, sugar, and industrial seed oils, have a disruptive effect on hormone production, including estrogen. Excessive sugar intake, for example, can spike insulin, which in turn influences oestrogen levels by increasing aromatase – the enzyme that converts testosterone into estrogen. This contributes to estrogen dominance, a condition increasingly common in both men and women.

Unlike highly processed diets, a Paleo approach focuses on whole, nutrient-dense foods that help regulate hormonal balance naturally. With balanced blood sugar, steady insulin levels, and reduced toxic exposure, your body is far better equipped to maintain optimal levels of estrogen and other vital hormones.

Environmental Estrogen Mimics

Another concern tied to hormone imbalance is the intake of xenoestrogens – chemical compounds that mimic estrogen in the body. These are found in pesticides, plastics (like BPA), cosmetics, and non-organic animal products. Although they aren’t biologically identical to human estrogen, they can still bind to estrogen receptors and cause havoc.

Following a Paleo lifestyle helps reduce your exposure to xenoestrogens. Prioritising organic produce, grass-fed meats, and natural personal care products can significantly reduce the load of synthetic estrogens on your system.

Paleo Foods That Support Healthy Estrogen Levels

Certain foods can naturally assist the body in metabolising and balancing estrogen levels. Cruciferous vegetables like broccoli, cauliflower, Brussels sprouts, and kale are rich in indole-3-carbinol, a compound that supports the liver’s ability to metabolise excess estrogen. The liver plays a key role in detoxifying hormones, and the nutrients in these vegetables directly assist that process.

Fermented foods like sauerkraut and kimchi promote gut health, which is also crucial in hormone regulation. The gut microbiome affects the reabsorption and excretion of estrogen. A healthy gut flora ensures that your body doesn’t recycle excess hormones, which could otherwise be reabsorbed and lead to imbalances.

Healthy fats like those from avocado, nuts, olive oil, and oily fish support hormone production as well. Hormones like estrogen are built from cholesterol and healthy fats, so removing fat entirely from the diet – as some mainstream diets suggest – can be counterproductive.

Exercise and Lifestyle: Key Components

Diet isn’t the only piece of the puzzle. Lifestyle factors like exercise and stress management play huge roles in regulating estrogen. High-intensity exercise can help lower estrogen dominance by promoting fat loss – especially from the abdominal region, where excess estrogen is often stored and produced.

Equally important is reducing chronic stress. Elevated cortisol (the stress hormone) can interfere with the balance of sex hormones, leading to increased estrogen in men and reduced progesterone in women. Simple changes like getting better sleep, meditating, walking in nature, and unplugging from devices can support a healthier hormonal environment overall.

Post-Menopausal Estrogen Balance

After menopause, estrogen levels naturally decline, and the source of estrogen shifts largely to fat cells and the adrenal glands. Maintaining a healthy body composition and supporting adrenal health become even more important. Paleo's anti-inflammatory approach, full of nutrient-rich, unprocessed foods, can be highly beneficial for post-menopausal women looking to stabilise their hormonal landscape without resorting to synthetic hormone therapies.

Supplements such as magnesium, vitamin D, and omega-3 fatty acids also support hormonal health and are often helpful during this stage of life. However, food should always be the foundation, with supplementation only where necessary.

Men and Estrogen: The Other Side of the Coin

Although estrogen is often associated with female health, it's vital for men as well. Estrogen in men supports brain function, libido, and bone health – but too much of it can lead to issues such as gynecomastia (male breast development), low testosterone, and abdominal weight gain.

Poor diet, excess alcohol, and high exposure to plastics are all culprits. Fortunately, adopting a Paleo framework – minimising processed foods, alcohol, and endocrine-disrupting chemicals – can go a long way in restoring hormonal balance for men.

Putting It All Together

Estrogen isn’t inherently “bad” – it’s essential. The real issue is imbalance, especially in today’s environment where so many factors conspire to push hormone levels out of their natural rhythm. By adopting a Paleo lifestyle, you support the body’s natural ability to regulate hormones by feeding it whole foods, reducing toxins, and living in alignment with how humans evolved to function.

If you suspect you might be dealing with estrogen dominance or imbalance, speak with a qualified healthcare provider who understands the interplay between diet, lifestyle, and hormones. Getting the right tests, such as saliva or Dutch hormone panels, can give you clear insights into what’s really going on.

Ultimately, balancing estrogen is not about quick fixes or drastic hormone therapy – it’s about supporting your body consistently with the right inputs. And a well-structured Paleo diet provides exactly that.

Manganese Paleo Diet Primal Supplements Mineral Vitamin Deficiencies-min

Manganese & The Paleo Diet

How are your Manganese levels? Does following a Paleo diet guarantee optimal micro nutrient levels? This week I'm focusing on manganese – and most importantly, how to make sure your levels are sufficient.

What actually is Manganese?

Did you see the word and thought I had spelt magnesium incorrectly? It is actually a trace mineral that regulates dozens of enzymatic reactions within the body. It is a crucial mineral.

If you are lacking in manganese some of the symptoms of deficiency include low thyroxine – or Thyroid Hormone T4 – as manganese is important for the production of T4.

Asthma is another area with links to deficiency of this trace mineral. There are links between low manganese levels in children and childhood asthma. Similarly there is a link between low dietary manganese intake and the incidents of asthma in adults.

Low HDL also has links to deficiency of manganese. Women who eat a low manganese diet will find their HDL drops dramatically.

Joint pain and osteoporosis can also be impacted. Bone density doesn't come down to just magnesium and calcium alone, with manganese also playing a significant part in overall bone health.

What causes low manganese levels?

Having too much iron in your system can result in low levels. While this isn't the cause of a deficiency for those who suffer from iron retention, or who absorb too much iron, manganese can reduce the absorption of dietary iron. Those who are on a Paleo diet (or following the Primal Blueprint) eating iron rich meat on a regular basis may be getting less manganese in their system than they need – especially if they are not eating most of the richest source of the minerals. Obviously if you do not eat enough manganese rich foods you’re not going to have enough manganese. If your diet consists mostly of beef and you don’t eat many nuts, shell-fish or berries, you may find you are not getting enough manganese in your diet.

As with all minerals, if they aren't in the soil, they don't get into the food chain. This means it is crucial to ensure your meat comes from animals who have been reared with a proper diet – and fed on grass, from soil with good mineral levels. Grain fed animals won't have had access to the same levels of minerals as their grass-fed equivalents. It's really important to know and understand where your food comes from.

Where can you get more manganese into your body?

Nuts are a great source of manganese with hazelnuts being the richest source and almonds having the lowest manganese source. Other nuts including macadamia’s pine nuts, walnuts and pecans are also good sources of manganese. Shell-fish such as mussels, clams and oysters are good sources, with mussels having the highest content of manganese. As always, it comes down to having a very varied diet, sourcing food from the highest quality sources wherever possible.

Ever thought about your manganese levels? Do you eat enough natural food sources? Please share your thoughts in the comments below.

Choline & The Paleo Diet

Continuing looking into deficiencies, this week falls to choline. What actually is choline and what is the effect of being deficient? Even on a strict Paleo diet, is it still possible to be deficient?

The precursor for acetylcholine is choline, which is a neurotransmitter that is responsible for memory and it is a very important part of two important phospholipids. The liver uses this to process fats within the body and to package lipids.

What symptoms should you look for that indicates you might be low in choline?

Elevated ATL levels – it’s the elevated alamine transaminase levels which could indicate you have a liver complaint that can be often caused by a choline deficiency. Research has shown that a fatty liver can be caused by low levels. As Choline is the precursor for acetylcholine which is involved in memory – impaired memory can often be a symptom of deficiency. Research carried out showed that patients given a supplement had improved memory.
Lower VLDL – while reducing VLDL might improve your lipid panel it can also see you end up with a fatty liver due to the fat not being packed away properly into lipoprotiens for dispersal.

How can a choline deficiency occur?

Offal is such a good source of choline that avoiding it could inadvertently result in a choline deficiency.

How can you add choline to your diet?

When it comes to choline, it’s all about eggs and offal! Beef liver contains by far the highest levels, as measured per 100 grams of food. In descending order the food with the highest levels are: veal liver, chicken liver, raw egg, turkey liver, turkey heart, wheat germ, bacon, pork loin and mutton.

You can also gain choline from the following foods, but in much smaller amounts: artichokes, cauliflower, pecans, Brussels sprouts, broccoli, macadamia nuts, almonds, pine nuts, cashews, chicken, pistachios, canned prawns, cod, ground beef and turkey gizzard.

Most nuts and seafood seem to be good sources, but when it comes to vegetables the levels vary – for example while Brussels sprouts, broccoli and cauliflower are good sources of choline, boiled kale hardly has any. Fruits and milk contain even less choline than vegetables, but some spices are good sources of choline, but as they are often used in such small amounts, they tend not to be reliable sources.

Unfortunately none of these foods come anywhere close to the amount of choline found in eggs and organs – liver and eggs alone have ten more times the amount present than most vegetables. It is the egg yolk that contains the most choline – not the egg whites. A 100 gram serving of just the egg yolks has 683 mg of choline while the same size serving of egg white only has 1.1 mg. To be able to eat an equal amount of both you would get 3 times more choline from your eggs if you threw the whites away.

Do you have much offal in your diet? I’d love to hear if choline levels are a concern to you – and also how you get offal into your Paleo diet?

Vitamin K2 & The Paleo Diet

2 Comments

So you follow a strict Paleo diet? Does this mean you’re in optimum health? Perhaps not. It’s still possible to become deficient in certain vitamins and minerals, even with a healthy Paleo diet. By being aware of some of the common deficiencies you can monitor your nutrition to ensure you avoid these. This week, we move from Magnesium, to Vitamin K2.

Vitamin K2 is one of those vitamins that a lot of people have never heard of, so it’s hard to know if you’re deficient in something you didn’t even know about!

What are some of the deficiencies linked to Vitamin K2?

Vitamin K2 deficiency has associations with many issues, such as osteoporosis, calcification of the arteries that may lead to heart disease and tartar build-up on the teeth – which if left on the teeth leads to tooth decay.

How do you become Vitamin K deficient?

Vitamin K2 is present in select foods, but of course when people don’t know about it, they don’t go out of their way to ensure they eat sufficient levels of foods that provide it. Also there is often a lack of the Vitamin K containing foods in the diets of the animals we actually eat, leaving the animals with nothing to convert Vitamin K via stomach fermentation. For example cows raised in paddocks are able to convert the Vitamin K1 found in grass into Vitamin K2. Those cows who have no access to grass will have very little Vitamin K1 to convert. Another reason to hunt out that grass-fed (and crucially grass-finished) beef.

What are some of the best sources or ways we can add Vitamin K2 to our diets?

Foods such as goose liver, grass fed butter, eggs, fish eggs and aged cheese (if you’re following more of a Primal diet, rather than a Paleo Diet) are good sources of Vitamin K2. Of course, if the animal didn’t eat well, it’s meat, eggs and dairy won’t be as rich in vitamins and minerals. This is why it really is so crucial to know where your food comes from – and make sure it is good quality.

On Dentist Weston A Price’s pioneering research trip, studying the teeth of various indigenous and native populations, he found that many tribes and natives had great jaw structure and teeth. Most of these groups had diets that were rich in fish oils and butter oil. The two ingredients provide all the necessities for strong bones and good teeth. At that time Vitamin A was a crucial factor that helped build strong teeth. The other, Ghee – or butter oil, was an unknown and Dr Price named it Activator X. In 1993 Vitamin K2 was discovered – and it is believed to be Dr Price’s Activator X.

Vitamin K comes in 2 forms – K1 and K2, which overlap when it comes to functionality – K2 seems to have a greater effect on forming teeth and bones while K1 actually reduces the requirement of K2, so it is better to concentrate on both vitamins together rather than just on one.

We create Vitamin K1 in our stomach from the bacteria in green vegetables, with some people also being able to create K2 as well. Unfortunately this creation occurs in the colon where it can’t be absorbed, which also happens with Vitamin B12, but, it is still beneficial to eat plenty of green vegetables, aged cheeses and Ghee to obtain the full range of Vitamin K vitamins.

Have you given much thought to Vitamin K? Do you think your levels are sufficient?

Why Vitamin K2 Matters More Than You Think

Even with a clean, whole-food diet like Paleo, vitamin imbalances and deficiencies can still creep in – especially when it comes to lesser-known micronutrients like Vitamin K2. While it often flies under the radar compared to vitamins like D or C, Vitamin K2 plays a vital role in long-term health. It is especially important for maintaining strong bones, healthy arteries, and proper calcium metabolism – all of which are essential goals for anyone living a Paleo lifestyle.

The Role of Vitamin K2 in Calcium Distribution

One of the most critical functions of Vitamin K2 is its ability to direct calcium to the right places in the body. It activates specific proteins such as osteocalcin and matrix GLA-protein that help bind calcium to bones and teeth, while keeping it out of arteries and soft tissues where it doesn’t belong. This ensures that calcium supports skeletal health rather than contributing to harmful plaque build-up.

Without sufficient K2, calcium may be misallocated – potentially leading to arterial calcification, kidney stones, or weakened bones despite adequate calcium intake. This makes K2 a crucial nutrient for anyone concerned about heart health, bone density, or general ageing.

Why Paleo Eaters May Still Fall Short

Although the Paleo diet promotes nutrient density and quality food sourcing, modern food systems complicate things. Even if you're eating eggs, butter, and meat regularly, if those animals weren't raised on pasture and grass, their fat-soluble vitamin content – especially Vitamin K2 – may be significantly lower than expected.

For instance, factory-farmed chickens and grain-fed cows do not convert as much K1 into K2 due to lack of access to their natural diets. This is one reason why sourcing from regenerative, pasture-raised producers is more than a trend – it’s a nutritional priority. The same is true for eggs: yolks from hens that roam and forage outdoors contain far more K2 than standard supermarket offerings.

Health Conditions Linked to Vitamin K2 Deficiency

Emerging research continues to highlight the correlation between low K2 levels and various chronic health conditions. Some of the most concerning include:

Osteoporosis: A deficiency in K2 can result in poor calcium absorption by the bones, contributing to decreased bone mineral density and an increased risk of fractures.
Cardiovascular disease: Without K2, calcium may deposit in the arteries instead of the bones, contributing to arterial stiffness and atherosclerosis.
Tooth decay and dental issues: Adequate K2 is believed to contribute to enamel strength and help maintain jaw structure.
Kidney health: Excess calcium in the wrong places can affect kidney function, especially when combined with low magnesium or poor hydration.

These are all conditions that Paleo followers are often actively trying to avoid – yet overlooking K2 may unintentionally undermine that goal.

Best Natural Sources of Vitamin K2

If you’re committed to staying Paleo while maximising your K2 intake, here are some of the most effective whole food sources:

Grass-fed butter and ghee: Rich in K2 when sourced from animals that graze naturally.
Egg yolks: Especially from free-range or pasture-raised hens.
Organ meats: Goose liver and chicken liver are surprisingly high in Vitamin K2.
Natto (fermented soy): Although not strictly Paleo, this is the richest known food source of K2 – especially the MK-7 subtype.
Fermented foods: Small amounts of K2 can also be found in traditional ferments like sauerkraut and aged hard cheeses (for those following a Primal or dairy-inclusive version of Paleo).

Whenever possible, aim for food-based sources over supplements. These not only provide K2 but come packaged with other synergistic nutrients that help with absorption and utilisation.

Should You Consider Supplementation?

Some individuals – especially those with gut issues, restricted diets, or limited access to pasture-raised foods – may benefit from targeted supplementation. If you do choose a K2 supplement, look for one that includes MK-7 (a highly bioavailable form of K2) and ideally pair it with Vitamin D3 and magnesium to optimise calcium metabolism.

Always consult with a practitioner before starting any new supplement, especially if you're managing a health condition or taking blood thinners, as Vitamin K can affect blood clotting factors.

Final Thoughts on K2 and the Paleo Approach

Vitamin K2 may be one of the most overlooked, yet critically important, nutrients in the modern diet. As the Paleo lifestyle continues to gain traction for its emphasis on ancestral nutrition and real food, understanding these nuanced vitamin requirements becomes essential.

By including more high-quality, animal-based and fermented foods – and focusing on where your food comes from – you can harness the benefits of Vitamin K2 while staying true to Paleo principles. It's a simple but powerful way to protect your bones, your heart, and your overall health in the long run.

Selenium & Deficiency On A Paleo Diet?

3 Comments

Despite following a healthy Paleo Diet, if not enough attention is paid to getting a wide variety of different foods, deficiencies are still possible. I've been looking into a number of the more common deficiencies to understand how to tweak your Paleo diet to ensure deficiencies don’t occur. This week, I've been looking into Selenium.

What is Selenium?

It is a trace mineral that is only needed in small amounts but it is essential for good health. Some of the functions selenium performs include helping regulate the thyroid gland, assisting the immune system and protecting our cells from the damage caused by free radicals. In dietary terms the selenium content of plant foods are proportionate to the soil concentration of selenium where the food was grown.

These days severe selenium deficiency in adults is very rare, particularly when following a healthy Paleo diet, but minor deficiencies do occur and that can have some rather unpleasant effects on our health.

Some of the selenium deficiency symptoms include polyneuropathy and muscle damage that can look a lot like the side effects of statins. Selenium supports the synthesis of the thyroid hormone and is needed for the conversion of the T4 thyroid hormone into the active T3 hormone. As a result deficiency can look like hypothyroidism.

So, how do you become Selenium deficient?

It can be as simple as just not eating enough Selenium rich foods, or if you suffer from an intestinal disorder such as Celiac, Chron’s disease or an ulcerative colitis these can all reduce the body’s absorption of selenium from foods. While deficiency does not cause those illnesses it can make the body more susceptible to illnesses caused by biochemical or infectious stress due to the role selenium plays in the immune system.

It can also be due to a lack of selenium in the soil where your food has been grown. Just like other minerals, it must be in the soil or it won’t be present in the food grown in the soil.

Where can you get it from, in keeping with the Paleo diet?

You can find good sources of selenium in lamb, turkey, prawns, salmon, cod, crimini and shiitake mushrooms, kidney’s, egg yolks and halibut.

Keeping your thyroid healthy is important with many people dealing with thyroid conditions such as hypothyroidism. There have been many research studies that have shown the benefits of selenium supplements when treating some thyroid conditions. One such study has found that selenium supplements have reduced the inflammation damage to the thyroid tissues. While studies have shown that selenium supplements can help prevent thyroid tissue damage there is more research needed to determine the long-term effects.

Making sure that your selenium intake is at its peak may give both your thyroid and immune system that little boost it needs to help function better. Whether you use supplements or include more selenium-rich foods in your diet it is important for those who are managing a thyroid condition to make sure their selenium intake is adequate.

As important as it is not to be deficient, it’s also important not to go over board. Over increasing your intake of selenium over long periods of time can lead to complications including garlic breath odour, hair loss, mild nerve damage, gastrointestinal upsets, white blotchy nails, irritability and fatigue.

The best option is to include selenium rich foods in your diet. While high in omega-6 fats it takes just a couple of Brazil nuts a day to boost your immune function and improve the amount of selenium in your diet.

Have you given much consideration to your Selenium intake? Which minerals and vitamins are you most concerned about, in your Paleo diet?

How Much Selenium Do You Actually Need?

The recommended daily intake for selenium varies slightly between countries, but for adults in Australia, the National Health and Medical Research Council recommends 70 micrograms per day for men and 60 micrograms per day for women. Pregnant and breastfeeding women may require slightly more. Since it's a trace mineral, you don’t need huge quantities – but consistency matters.

The Best Paleo-Friendly Sources of Selenium

While Brazil nuts are famously rich in selenium (just one or two nuts can provide well over 100% of the daily requirement), they aren’t your only option. For those following a more varied or strict Paleo approach, it’s helpful to include a mix of selenium-rich options:

Wild-caught fish – Tuna, sardines, salmon, and especially cod are excellent sources.
Shellfish – Oysters, prawns, and mussels contain respectable selenium levels.
Grass-fed meats – Lamb liver, beef kidney, and muscle meat offer both selenium and other vital micronutrients.
Pasture-raised eggs – Especially the yolks, which are rich in selenium and choline.
Crimini and shiitake mushrooms – A great option for those after more plant diversity.

Rotating these foods through your weekly meals can help ensure you stay on top of your selenium intake without relying too heavily on just one source.

Selenium Absorption and Synergy with Other Nutrients

It’s not just how much selenium you eat – it’s how well you absorb and utilise it. Selenium works synergistically with other nutrients, particularly:

Iodine – Both are essential for thyroid function. If you’re low in one, the other may not be as effective.
Vitamin E – Helps reduce oxidative stress alongside selenium. Good fat sources like almonds and sunflower seeds (if tolerated) can help.
Protein – Since selenium is incorporated into selenoproteins, an adequate protein intake helps support this function.

If you're supplementing or relying on specific foods, consider whether you're supporting those nutrients in a broader context, too.

Soil Depletion and Selenium Content in Australia

Australia’s soils are known to be naturally low in selenium – particularly in the southern and eastern regions. This means produce grown in these areas may have lower levels, even if they would normally be a good source. For example, broccoli grown in selenium-rich soil may provide a decent amount, whereas the same broccoli from another farm may contribute very little.

Because of this, it’s a good idea to diversify the origins of your food when possible or choose animal products where the feed is fortified with selenium (common in ethical Australian livestock farming). Buying from farmers who can tell you about their soil quality and animal diets can make a meaningful difference.

What About Supplementing?

If you suspect your intake is low – perhaps due to autoimmune thyroid issues, absorption problems, or limited food variety – a low-dose selenium supplement may help. But proceed with caution. Supplements often provide 150–200 micrograms per dose, which can be excessive if you're already consuming selenium-rich foods.

Ideally, work with a health practitioner to test your selenium levels before supplementing long term. Hair mineral analysis and blood serum tests can both provide useful data.

Signs You May Be Getting Too Much

Although rare, selenium toxicity (known as selenosis) can happen – particularly from supplements or eating large quantities of Brazil nuts daily. Some symptoms to watch for include:

Brittle hair or nails
Digestive discomfort
Fatigue or irritability
Unusual breath odour (often described as “garlic-like”)

Again, balance is key. Aim to meet your needs through whole foods, monitor symptoms, and seek testing if you’re unsure.

How to Add More Selenium-Rich Foods to Your Paleo Meals

Here are a few simple, Paleo-friendly ideas to boost selenium naturally in your week:

Breakfast: Add two eggs with sautéed mushrooms and spinach in ghee or olive oil.
Lunch: A salad with grilled salmon, avocado, and a boiled egg. Top with a citrus olive oil dressing and a sprinkle of sesame seeds.
Dinner: Grass-fed lamb chops with roasted root vegetables and a side of steamed broccoli.
Snacks: One or two Brazil nuts, or a small portion of prawns with lemon and herbs.

Takeaway

While selenium deficiency isn’t especially common on a nutrient-dense Paleo diet, it’s still worth being aware of – especially if you’re dealing with thyroid issues or have limited variety in your meals. Focus on diverse, whole food sources, be mindful of soil quality and absorption, and only supplement if there’s a genuine need.

Iodine

4 Comments

So you’re following a “perfect” Paleo diet… surely you can’t be deficient in any vitamins or minerals that your body needs? Well, you might be surprised; have you thought about your iodine levels lately?

I've been looking into some of the popular supplements that people take, and minerals that some are careful to ensure they are not deficient in. I’ll be writing about a few of the popular ones, but iodine is one of the first minerals that regular seems to be spoken about.

What actually is iodine?

It’s a trace element that has quite a big impact on our health and is especially associated with our thyroid. While iodine deficiency is mainly linked with third world and developing nations, research shows that even those living in developed countries like Australia or the United Kingdom have been found to be deficient. It’s probably no surprise, given the SAD diet so many people in the developed World live on.

Iodine deficiency is not a good thing and can cause a number of health issues.

Conditions such as Goitre can be caused by iodine deficiency. The thyroid gland enlarges, as it lacks the necessary iodine in order to compensate for the imbalance. This produces a large and highly visible lump in the neck. Not pretty.

Cretinism occurs when a woman is iodine deficient during a pregnancy. This can result in the child being born with a lower IQ and abnormal neuro-development.

Another result of iodine deficiency is Hypothyroidism. Iodine is one of the major ingredients in the thyroid hormone, so where thyroid lacks enough, it will reduce the thyroids ability to makes the hormone. Symptoms of a thyroid lacking iodine include – elevated blood lipids, infertility, weight gain and the inability to lose weight, dry skin, hair loss and a lack of libido – just to name but a few.

So why do iodine deficiencies occur?

Especially on a Paleo diet, when you eat natural, real foods? Foods such as sea food and seaweed are rich in iodine – so not having many of these foods in your diet, makes it harder to get decent levels of iodine.

A common source of iodine is iodised salt – which of course on a Paleo diet, is often replaced with mineral and sea salts – naturally iodine free!

Some foods are rich in Goitrogen, such as broccoli. If eaten to excess, these foods may interfere with the iodine uptake needed by the thyroid gland. While this doesn’t lead to a whole body deficiency it does limit the thyroids ability to get the amount of iodine it needs.

Where can you get iodine from?

Seaweed is a great source, especially from kelp (or Kombu) and hijiki, just add a strip to your next pot of chili, soup or curry. Eat more seafood – crustaceans, fish, and shellfish – anything that lives in the ocean, provided it is high quality. While the iodine content of fish varies you can get the most from abalone, codfish and pollack. The way you cook also determines how much iodine will remain. If you boil fish it will lose most of its iodine content but if you fry it most of the iodine content will remain. Grilling retains more than boiling does, but a little less than frying.

Free range eggs are another great source – although the specific amount will depend on the laying hens diet – if there is iodine in the chicken’s diet it will show up in the yolk.

Finally supplements are a popular alternative to ensure you are getting sufficient levels of iodine in your paleo diet.

So how do you ensure you get enough Iodine?

Dr Terry Wahls Paleo Diet Multiple Sclerosis-min

Paleo & Multiple Sclerosis

I've been reading a lot about Dr Terry Wahls recently. Dr Wahls was diagnosed with Multiple Sclerosis in 2000 and immediately went on a quest to learn as much as she could about the chronic neurodegenerative disease – and how she could delay what seemed to be the inevitable decline to the illness.

After extensive research and experimentation she started eating essentially a Paleo diet, ensuring this included nine cups of non-starchy vegetables and berries each day. This diet ensures 45 nutrients, that appear to be essential to the brain, are consumed in sufficient quantities. Of course, a standard western diet is woefully deficient in these nutrients. Over time she reversed her MS; an amazing achievement.

It doesn't seem to be any great surprise that a diet of natural, real food can transform many diseases. But I was surprised to see MS Australia fundraising earlier this week – by selling cupcakes! I'm sure they sell well and I realise the people they are selling them to don’t have Multiple Sclerosis. But you wouldn't see a lung cancer charity fund raising by selling lighters. It surprises me to see so many charities fund raising by selling products that clearly don’t help with the condition.

What do you think about Dr Terry Wahls protocol and her recovery?
