Following on from last weeks post about Selenium, this week I'm focusing on Magnesium. You might think following a Paleo diet makes it impossible to develop deficiencies – but unfortunately that isn't the case. However, by focusing on common deficiencies, you can adapt your Paleo nutrition to ensure your micro nutrient levels are optimum.
Despite Magnesium being something that is so important in your diet, so many people struggle to get enough in their system through diet alone. In fact research has shown that in the United States alone only half of the adult population actually achieve the recommended daily allowance (though as we know, the quoted “daily allowances” are often woefully low anyway). It is this low intake of magnesium that has been linked to common diseases such as asthma, osteoporosis, type 2 diabetes, colon cancer, metabolic syndrome and heart disease.

Just some of the many and varied symptoms that can show a lack of magnesium in the diet include – cramping, constipation, migraines, insulin resistance, fibromyalgia and hypertension.
So how do you lack magnesium in your system/ and Paleo diet?
It’s become popular to filter drinking water, which removes Magnesium, by filtering and purifying devices on your home taps or filter bottles. A general lacking of minerals in the soil is another culprit. If it isn’t in the soil, it can’t get into the produce grown there. Plants grown in mineral rich soil will have higher magnesium contents then those that are grown in soil with little or no magnesium. In general, lacking magnesium rich foods, especially plant foods, in your Paleo diet, is the main reason for deficiency.
Where can you get magnesium?
Mineral water contains high concentrations. Also, nuts, halibut, espresso, seeds and dark chocolate (a great excuse!) Leafy greens such as spinach and Swiss chard are excellent sources. Supplements those ending in “ate” such as taurate, citrate and glycinate are what is known as chelated magnesium and they seem to be the best when it comes to being absorbed into the body. Alternatively you can apply magnesium oil for transdermal absorption which absorbs best when applied on the inner arms and rib cage. Bathing in Epsom Salts is another great way to increase levels in the body.
There are at least seven different types of magnesium available (and perhaps many more) that you can buy to take orally and they include magnesium carbonate, magnesium chloride, magnesium oxide, magnesium citrate, magnesium hydroxide, magnesium sulphate and magnesium lactate. With so many variations out there it is no wonder people get confused when shopping! Make sure you do your research and choose the best supplement for your needs, of you think you need to take one.
Magnesium Oxide is one of the most popular supplements which are easily found at supermarkets the reason for this is because it is so cheap to produce. The down side to that is that because it isn’t absorbed into the body well, it will do very little for you. Try for a citric acid and magnesium carbonate blend, which is very popular and can be found in many of the better quality brands – when mixed with water it creates ionic magnesium citrate which has a much higher absorption rate.
Magnesium’s Role in Your Overall Health
Magnesium is one of the most critical minerals in the body, playing a role in over 300 enzymatic reactions. These include protein synthesis, blood glucose control, blood pressure regulation, nerve function, and muscle contraction. Magnesium is also required for the structural development of bone and is involved in the transport of calcium and potassium across cell membranes, which is vital to maintaining a healthy heart rhythm.
How Magnesium Impacts Stress and Sleep
In today’s busy lifestyle, stress is practically unavoidable, but magnesium can help mitigate its effects. Chronic stress leads to magnesium depletion, creating a vicious cycle. Increasing your intake of magnesium may help to balance cortisol levels and improve resilience to stress. Furthermore, magnesium supports the production of GABA (gamma-aminobutyric acid), a neurotransmitter that encourages relaxation and restful sleep.
For those following a Paleo diet, ensuring adequate magnesium can also assist in falling asleep faster and achieving deeper sleep cycles. If you're finding it hard to switch off at night, incorporating magnesium-rich meals in the evening or using magnesium oil topically might be worth trialling.
Why Magnesium Absorption Can Be Challenging
Even with the best dietary intentions, absorption isn’t always guaranteed. Excess calcium intake, certain medications (like proton pump inhibitors or diuretics), gastrointestinal conditions, and chronic stress all impair magnesium uptake. If you’ve been eating plenty of greens and nuts but still notice symptoms of deficiency, it could be due to impaired absorption rather than intake.
For this reason, many Paleo followers experiment with magnesium supplements or topical applications like magnesium oil or Epsom salt baths, especially during periods of heightened stress, intense physical training, or poor sleep.
Creative Paleo-Friendly Ways to Boost Magnesium Intake
- Make your own trail mix: Combine pumpkin seeds, sunflower seeds, almonds, and Brazil nuts. This magnesium-rich mix makes for an ideal afternoon snack.
- Add leafy greens to every meal: Blend spinach into smoothies, sauté Swiss chard with garlic for dinner, or include baby kale in omelettes.
- Bone broth with a twist: Add a handful of seaweed or magnesium flakes into your next batch for a mineral-rich broth.
- Dark chocolate treats: Use raw cacao (which is high in magnesium) to make homemade Paleo chocolate bark with nuts and dried berries.
What Symptoms Might Improve with More Magnesium?
Magnesium affects so many systems that deficiency can show up in varied and unexpected ways. If you suffer from frequent tension headaches, migraines, restless legs, fatigue, mood swings, or sensitivity to noise, your body could be signalling low magnesium stores. Many people also notice improved bowel regularity, fewer muscle cramps, and more stable energy after increasing their intake.
How to Know if You’re Getting Enough
Unfortunately, testing for magnesium isn’t always straightforward. Only about 1% of the body’s magnesium is found in the blood, so standard serum tests may not reflect deficiency accurately. Instead, consider whether you have symptoms, review your intake, and trial a magnesium-rich protocol for a few weeks to see how you feel. Some people keep a magnesium journal, tracking symptoms like sleep quality, cramping, or energy to detect patterns.
Tips for Maximising Magnesium Absorption
- Soak nuts and seeds overnight before eating to reduce phytic acid, which can block magnesium absorption.
- Balance calcium and magnesium intake. Too much calcium can interfere with magnesium, so ensure you're not over-supplementing calcium without magnesium.
- Limit caffeine and alcohol, both of which increase magnesium excretion.
- Try smaller, more frequent magnesium-rich meals rather than large, infrequent doses.
Should You Supplement or Go Natural?
While whole foods are always preferable, some people find that even with a nutrient-dense Paleo diet, magnesium levels fall short—particularly if dealing with ongoing stress or sleep issues. In this case, a supplement might be a helpful addition. Look for magnesium citrate, bisglycinate, or malate for better absorption. Always consult a qualified practitioner if you have underlying health conditions or are on medications that could interact with supplementation.
As with any nutrient, the key is finding what works best for your body. The Paleo diet provides an excellent foundation of nutrient-rich foods, but tuning into symptoms and biofeedback can help you fill in any gaps effectively.
How do you think your levels are looking? Do you eat enough Magnesium rich foods, or supplement?
