Vitamin B9 (Folate) on the Paleo Diet
Growth and development – this is what Vitamin B9 is most vital for. Growth and development actually comprise a whole set of processes in the human body, with cell division and DNA production perhaps the most important ones, and so Vitamin B9 becomes especially important during pregnancy, lactating, and early growth stages. What is more, it promotes nerve function, helps to prevent osteoporosis-related bone fractures, and can play a role in the prevention or treatment of a number of medical conditions: anaemia, cervical tumours, depression, glossitis, insomnia, myelopathy, ovarian tumours, restless leg syndrome, schizophrenia, uterine tumours.
Unfortunately, Vitamin B9 deficiency is one of the most common nutrient deficiencies, suffered often by pregnant women, by chronic alcohol abusers, and by those with poor nutrient absorption disorders like ulcerative colitis. How can you recognise a deficiency? This can be characterized by muscular fatigue, insomnia, depression, forgetfulness, irritability and gingivitis or periodontal disease.
Vitamin B9 actually comprises two compounds – Folate which is found in natural foods, and Folic Acid which is synthetic. Though similar, Folic Acid that is used for fortifying processed foods is absorbed to nearly half the level of Folate. Therefore, it makes much more sense to focus on whole foods to get adequate Vitamin B9 consumption, and for this the Paleo Diet is a great solution, as it promotes a natural way of eating in the name of long-term vitality and health.
How much Vitamin B9 do you need in your diet?
The daily recommended amount of folate is 400μg. Since it is easily excreted from the body, excessive intakes are very difficult to reach.
Which foods can you get Folate from?
- Liver – Whichever your preferred choice of animal, you’ll get a great amount of Vitamin B9 from it. Turkey liver, however, is the richest source, with 173% of your daily need of Folate in just 100g.
- Spinach – leafy greens are another fantastic source for Vitamin B9, with spinach as the forerunner. In 1 cup of cooked spinach, you’ll get 65% of your daily need of Folate.
- Beets – If you’re looking for a Folate-rich vegetable, beets are your best friends. 1 cup of raw beets covers 37.1% of the daily need of Vitamin B9. Beet salad, roasted beets, beet soup – the choices are endless!
- Romaine lettuce – When preparing a green salad, opt for romaine lettuce. 2 cups of this crunchy salad will provide 32% of your daily Folate need.
- Asparagus – In springtime, one of the best sources for Vitamin B9 is asparagus, providing 37% of your daily need in a 100g serving.
- Papaya – For an exotic dessert, reach for a papaya. In just one fruit, you will get 28.9% of your daily intake need of Vitamin B9.
- Avocado – Yet another reason for having a daily avocado is its Folate content. One cup of mashed avocado (time for guacamole?) amounts to 29.6% of your daily need of Vitamin B9.
- Cauliflower – For a Folate-rich change to those beets, reach for cauliflower. In 1 cup of raw cauliflower, there’s 15.2% of your daily Folate need. And it’s a delicious snack when eaten raw!
What else do you need to know about Vitamin B9?
Vitamin B9 is not very stable, and its content undergoes a relevant loss in the case of non-airtight storage, overcooking and reheating of food. In addition, green and black teas counteract the absorption of the vitamin and thus should be minimized if you focus on Vitamin B9 consumption. However, animal products that contain folate are more stable when it comes to cooking than plant products, so you shouldn’t have a problem if you focus on those. Luckily there’s no lack of them in the Paleo Diet!
Why Folate Absorption Matters More Than You Might Think
When it comes to getting the most from your diet, it's not just about what you eat — it's also about how well your body absorbs it. Even if you're eating a folate-rich diet, certain habits or health conditions can impair absorption. For instance, those with gut health issues, such as coeliac disease or inflammatory bowel conditions, may not absorb Vitamin B9 efficiently. This can make even a good diet fall short in terms of real nutrient delivery. If this sounds like you, it might be worth looking into digestive health as a starting point.
Signs You Might Be Low on Vitamin B9
Beyond the better-known signs like fatigue and insomnia, B9 deficiency can show up in subtle ways. These can include mouth sores, swollen tongue, or a pale complexion. Because folate plays a crucial role in red blood cell formation, low levels can quickly result in anaemia — leaving you feeling unusually tired or short of breath. It's one of those nutrients that you may not notice you're missing until you're already affected.
Can You Get Too Much Folate?
Folate from food sources is safe, even at higher levels, because your body excretes what it doesn't need. However, synthetic folic acid found in fortified foods and supplements is processed differently by the body. There is some concern that excessive folic acid, particularly from supplements, might mask Vitamin B12 deficiency — a serious issue especially for older adults. That's why sticking to food sources, as the Paleo approach recommends, is a more balanced long-term strategy.
Pregnancy and Folate: Why It’s Non-Negotiable
Women who are pregnant or trying to conceive are typically advised to take additional folic acid supplements due to the nutrient’s role in preventing neural tube defects in the developing baby. While whole food sources are always ideal, supplementation can be necessary during this stage of life. Liver and leafy greens are particularly good additions to a pregnancy-focused Paleo plate — just be mindful of moderation with liver due to its Vitamin A content.
Beyond Pregnancy: Folate’s Ongoing Role in Women’s Health
Even outside of pregnancy, folate plays an important role in hormone regulation and reproductive health. There’s emerging evidence linking adequate folate levels to a reduced risk of ovarian and uterine issues. Because of its impact on cell division, it’s also a nutrient worth monitoring as women age. Keeping folate levels stable through natural food sources can support ongoing hormonal balance and energy levels.
Smart Storage and Cooking Tips
To retain as much folate as possible, it’s best to store produce in airtight containers in the fridge and use it promptly. When cooking, avoid boiling leafy greens for too long. Steaming or lightly sautéing can help preserve their nutrient content. If you’re preparing a large batch of food to store, consider freezing it soon after cooking to lock in the folate content.
Paleo Recipes That Naturally Include Folate
One of the benefits of a Paleo lifestyle is that so many folate-rich foods are already part of the core template. Think of a meal like grilled chicken livers served with sautéed spinach and roasted beets — all incredibly rich in Vitamin B9. Or a hearty cauliflower and avocado salad dressed with olive oil and lemon. Even a smoothie made with papaya and spinach can pack in a good folate punch. By being intentional with your ingredient choices, you’ll find it’s not difficult to meet your daily needs.
The Bottom Line on B9
Folate is one of those nutrients that affects many crucial systems in the body — from brain function and mood to cell repair and energy production. The Paleo diet naturally lends itself to an excellent folate intake, thanks to its focus on whole, unprocessed foods. By being conscious of storage, cooking methods, and absorption factors, you can maximise the benefits of Vitamin B9 and support your long-term health in a powerful way.
