B Vitamins and Brain Benefits

B-complex supplements typically pack all eight B vitamins into one convenient pill. This includes B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folate), and B12 (cobalamin).

Here, the most important ones for those with a brain injury are perhaps B6, B9, and B12. B6 involves amino acid metabolism, red blood cell production, and the creation of neurotransmitters – extremely important functions for brain health.

Vitamin B1

In fact, thiamine is often used to treat problems with metabolism.  A serious deficiency in vitamin B1 can result in brain problems.  Brain problems associated with vitamin B1 deficiency include confusion, memory loss, and mood changes such as apathy.  Additionally, some evidence supports the belief thiamine can help increase energy and improve learning.  People who drink a lot of alcohol might have a high risk of B1 deficiency.  The recommended dietary allowance for adults is 1.1 mg per day for women and 1.2 mg a day for men. You can find vitamin B1 in the following:

  • Yeast

  • Meat

  • Nuts

  • Beans

  • Cereal grains such oats and rice



Vitamin B6

Vitamin B6 is available in the form of supplements and often consumed balanced diet.  Below are examples of foods that are rich in vitamin B6.

  • Whole grains

  •  Chicken

  • Rice

  • Beef

  • Lentils

  • Liver

  • Bananas

  • Avocados

  • Beef

  • Fish

  • Carrots

  • Soybeans

Vitamin B9

B9, or “Folate,” is required for cell growth, amino acid metabolism, the formation of red and white blood cells, and proper cell division.  Folic acid, also known as vitamin B9, helps your brain get the blood it needs.  Studies also suggest that daily supplements of folic acid can reduce the likelihood of certain age related brain problems including dementia. Folic acids main role is to maintain the cell’s genetic code, its DNA for cell reproduction.  If your body is not getting enough folic acid you may suffer from forgetfulness, a common side-effect of TBI.

Vitamin B12

While all B vitamins are important for brain health, B-12 is perhaps the most important. Unfortunately, it is also the most common B vitamin deficiency in western countries. B-12 deficiency has been linked to memory loss, cognitive decline, depression, decreased mobility, and fatigue.  B-12 is critical for the production of myelin sheaths, which surround nerve cells and are essential for efficient conduction of nerve signals [18].



B-12 is important for the production of energy within the body’s cells – as a result fatigue is one of the most common symptoms of B-12 insufficiency [18].  In fact, B-12 is so important for the brain that its deficiency has been linked to measurable brain atrophy [19].  When choosing a B-12 supplement, opt for the methyl form which is more stable and readily used by the body than its synthetic counterparts.  When you just want to get better, you want to take every opportunity you can to get you there quicker. These supplements might be the missing solution you need but always consult with a trusted practitioner prior to starting any.
