The Best Vitamins For Brain


Health is the most important thing in life. This includes health of our brain – one of the vital organs in our body that is crucial for our optimal daily performance. Vitamins for brain are necessary to maintain a healthy brain.


What to do if you notice your brain is not functioning properly? Maybe the problem hides in your diet. Diet of an average person that consists mostly of precessed foods, does not meet daily requirements for the vitamins that body needs. One of the studies even showed that 40 – 60 percent of adults are not getting enough vitamins trough their diet.



Suboptimal brain functioning from vitamin deficiency is usually subtle and goes undetected for a long time. Changes in a diet can improve the problem, but often just a healthy diet is not enough to supply the brain with all the vitamins it needs. In this case adding supplements for brain is an option that can help to maintain brain healthy, prevent possible damage caused by free radicals or stress and improve memory and cognitive performance.


Some of the best vitamins for brain, that can help preserve and improve your intellectual and emotional health are:


1. B Vitamins are especially important in preserving aging brains, protecting against memory loss and brain diseases. The most important vitamins for brain from this group are vitamins B6, B12 and B9 (Folic Acid). They protect neurons in brain, improve memory, help in brain development and are very important for people under stress. B vitamins can be found in vegetables such as spinach and other dark leafy green vegetables, broccoli, asparagus, black beans, soybeans, fruits such as strawberries, melons, oranges, meat, fish, cereals, algae such as Spirulina and are often taken as supplements.


·        Folic acid improves memory, alertness, cognition and protects brain from excessive amino acid homocystein, that can damage brain cells. Low levels of folic acid can increase risk of depression. It is found in spinach, broccoli, bananas, strawberries, whole wheat bread, asparagus, peas and in supplements. 

·        Vitamin B12 helps maintain health of nerve cells, increases mental alertness, protects against some mental problems such as depression, prevents senility, memory loss and enhances brain power.  

·        Vitamin B6 helps to improve memory.


2. Antioxidants protect brain tissue from free radicals that can damage brain structures. Vitamins C and E are one of the most important antioxidants for brain. The best foods rich in antioxidants are prunes, blueberries and other berries, garlic, raisins and spinach. You can also find them in green tea, nuts, seeds and in supplements. Multivitamins that include vitamins C, B complex and E are one of popular choices.


·        Vitamin E is an antioxidant that protects brain and nerve cells against damage caused by free radicals. It is a powerful vitamin that can protect against Alzheimer’s disease delay its progress. If boosts blood circulation that influences good brain functioning.You can find it in cereals, vegetable oils, vegetables, nuts, grains and different supplements. 

·        Vitamin Cis another antioxidant that protects against free radicals that can damage brain cells. You can find it in fruits such as lemons, oranges, grapefruits, berries or kiwi, vegetables such as legumes, chili and in supplements.

3. Other vitamins for brain that improve its functioning and vitality are:


·        Vitamin D protects pathways in the brain and improves memory. One of the studies also showed that there is a link between vitamin D deficiency and depression in older people. The best way to receive daily dose of vitamin D is by exposure to the sunlight and by taking supplements.

·        Vitamin A enhances the ability to learn by improving communication between brain cells in the hippocampus- part of the brain associated with memory and learning. It is also needed in development of the nervous system in an embryo. You can find it in carrots, spinach, egg yolks, cantaloupe, liver and in supplements. 


Brain also requires other nutrients besides vitamins. Omega-3 fatty acids are one of the essential nutrients for brain, found in fish, walnuts, flax seed oil and are often taken as supplements. They protect brain cells from inflammation, improve memory, moodiness, brain functions and even influence IQ in children.


These findings show that you have to eat right for the optimal brain performance. Look into your diet to find out if you consume enough of the vitamins for brain and omega-3 fatty acids. If your diet consists mostly of processed foods like white flour, sweets and pre-prepared meals, there is a good chance that you do not get all the nutrients you need. In this case try to include more fruits, vegetables and fish (at least 2-3 times per week) on your menu or consider taking supplements for brain to keep it healthy and fit for a long time.

  • help to maintain healthy heart
  • joint function and
  • can even help with weight loss.

Great for weight loss, pregnant women and people with neurological problems

Study has shown that people who consume enough of fish oil burn fat at a higher rate and loose weight quicker. Fish oil helps to reduce belly fat that causes inflammation and thus prevents damage to the brain and circulatory system. Omega-3 fats are also very beneficial for pregnant women and brain development of fetus. They help to slow down inflammation in the brain that causes Alzheimer’s disease and are useful in neurology, for people with neck and back problems.

Fish or Omega-3 supplements for brain?

Research show that Japanese men that eat fish, full of healthy omega-3 fats, every day, have far less heart disease than other men. Japanese eat around 3 ounces of fish per day, that provides around 1300 milligrams of Omega-3 fats. That is much more than an average western person consumes, so taking the Omega-3 supplements, is a good idea. An alternative is eating fish, but that requires some caution, since large fish often contain heavy metals that are bad for our health.

Vitamins For Brain: Vitamin D



Vitamin D  is one of the valuable vitamins for brain and a  fat-soluble vitamins that constitutes two major forms: vitamin D2 or ergocalciferol and vitamin D3 or cholecalciferol. Vitamin D2 is synthesised by plants and is sometimes considered vegetarian source of vitamin D, whilst vitamin D3 is synthesised by the body. Vitamin D is naturally present in a number of food sources and dietary supplements, and is also manufactured with the aid of sun exposure. It is produced within the body when ultraviolet-B or UVB rays from sunlight reaches the skin. The liver and the kidney eventually help to convert vitamin D to an active hormone form.

Vitamin D2 Vitamins For Brain: Vitamin D

Functions of Vitamin D

Vitamin D plays several key roles in the maintenance of organ systems. For example:

  • Vitamin D helps regulate calcium concentrations in the blood. Since it works more like a hormone, its active form, calcitriol acts with the parathyroid hormone or PTH. If the calcium level is low, this would trigger the secretion of PTH, which would stimulate the conversion of vitamin D to calcitriol. Calcitriol would then act to increase calcium absorption in the intestines, calcium resorption in the kidneys and stimulate calcium release from the bones.
  • Vitamin D helps maintain blood phosphorus levels. Low levels of vitamin D can result to an overactive parathyroid gland. Also with inadequate phosphorus in the body, bones cannot undergo normal mineralisation.
  • It is also said that vitamin D benefits the immune system since the T-cells or immune cells have receptors for vitamin D. It acts by boosting phagocytosis, the bodily functions to combat tumours, modulate neuromuscular and immune functions and reduce inflammation.
  • Vitamin D is also responsible for maintaining normal cell growth and function. It may be an important element to the prevention and treatment of cancer. It has also been suggested that vitamin D plays a role in regulating the growth and function of brain cells.
  • Research studies suggest that vitamin D, because of its anti-inflammatory effect, plays a role in providing protection against osteoporosis, hypertension, cancer, type 1 diabetes, psoriasis and numerous autoimmune diseases.

Besides that, vitamin D may play a role in prevention or tratment of the following health conditions:

  • Asthma (severe childhood)
  • Atherosclerosis
  • Bladder cancer
  • Breast cancer
  • Chronic fatigue syndrome
  • Colon cancer
  • Congestive heart failure
  • Crohn’s disease
  • Ovarian cancer
  • Depression
  • Epilepsy
  • Fibromyalgia
  • Heart attack
  • Hypertension
  • Inflammatory bowel disease
  • Insulin resistance
  • Kidney disease
  • Leprosy
  • Liver disease
  • Metabolic syndrome
  • Multiple sclerosis
  • Myofascial pain syndrome
  • Osteoporosis
  • Periodontal disease
  • Preeclampsia
  • Psoriasis
  • Rectal cancer
  • Rheumatoid arthritis
  • Senile dementia
  • Stroke
  • Tinnitus
  • Tuberculosis
  • Type 2 diabetes
  • Ulcerative colitis

Deficiency Conditions

There may be certain underlying causes of vitamin D deficiency. It can result from:

  • Inadequate vitamin D intake together with inadequate sun exposure
  • Certain disorders that compromise vitamin D absorption
  • Conditions that can impair the conversion of vitamin D metabolites such as kidney or liver diseases or hereditary disorders.

Insufficient vitamin D intake can have serious effects on the bones, which can make them thin, brittle or deformed. Vitamin D deficiency often results in conditions like:

  • Rickets which is common in children and is characterised by delayed growth and deformity of long bones.
  • Osteomalacia, which occurs in adults and results in thinning of the bones. Signs of proximal weakness and bone fragility are familiar characteristics.
  • Osteoporosis which is a condition wherein the bone mineral density is reduced and bone fragility is increased.

Lack of vitamin D may also be linked to increased susceptibility of several chronic diseases like high blood pressure, cancer, tuberculosis, periodontal disease, multiple sclerosis, chronic pain, schisophrenia, depression, affective disorders, peripheral arterial disease and a number of autoimmune diseases such as type-1 diabetes.

Deficiency Symptoms in Adults and Infants

Signs of vitamin D deficiency includes muscle aches, myopathy or muscle weakness and bone pain. These symptoms can occur at any age. Pregnant mothers who have vitamin D deficiency can also cause fetal deficiency.

In younger infants, rickets can produce a condition called craniotabes or softening of the skull. In older babies, rickets can impede or delay sitting and crawling and the closure of the fontanels; bossing of the infants’ skull and presence of costochondral thickening or what is referred to as ‘rachitic rosary’. Children with rickets aged 1-4 years old experience epiphyseal cartilage enlargements on the long bones and delayed walking. Older children and adolescents can experience pain upon walking and in worst cases it can result in ‘bowlegs’ or ‘knock-knees’.

Tetany that is caused by hypocalcemia may go along with vitamin D deficiency in infants and adults. This condition can lead to symptoms such as loss of feeling in the lip or tongue areas and the fingers, facial spasms, and at worst, seizures.

Recommended Daily Dose of Vitamin D

Doses or intake of vitamin D is determined according to age groups. These amounts are vital to maintain normal growth and bone health and also normal calcium metabolism in the body. The adequate intakes or AIs for vitamin D indicated are based on the supposition that the vitamin D is not synthesized by sunlight exposure.

From birth to age 13, the recommended AI for children is 5 mcg or 200 IU; for both males and females aged 14-50 years old, 5 mcg or 200 IU is needed; for both males and females aged 51-70 years of age, 10 mcg or 400 IU is required; both males and females reaching the age of 71 and up require 15 mcg or 600 IU of vitamin D. Pregnant and lactating mothers need 5 mcg or 200 IU of the vitamin.

Vitamin D Sources 300x300 Vitamins For Brain: Vitamin D


Vitamin D Food Sources

Only a few food sources contain vitamin D. Best sources of vitamin D are fish meat and fish liver oils. There are also small amounts of vitamin D, in the form of vitamin D3, found in dairy products like cheese and egg as well as beef and liver. Some types of mushrooms also contain varying amounts of vitamin D2.

Common sources of vitamin D include the following:

  • Cod liver oil
  • Fish like salmon, mackerel, tuna, sardines
  • Milk including non-fat, reduced fat, whole or vitamin D fortified
  • Margarine
  • Cereals
  • Egg
  • Beef liver
  • Swiss cheese
  • Fortified orange juice
  • Fortified rice or soy beverage

The Need for Increased Amounts

Since obtaining sufficient amounts of vitamin D in the diet can be quite difficult, many people now consume vitamin D fortified foods in order to maintain a healthy dose of the vitamin. There are some groups however who need increased amounts of vitamin D:

  • Breastfed infants because vitamin D cannot be supplied by breast milk alone
  • Older people due to the fact that synthesis of vitamin D decreases with age and the ability of the kidney to convert vitamin D diminishes.
  • People with limited sun exposure especially those living in northern latitudes, those wearing robes or head covers or those with occupations that prevent them from having sun exposure.
  • People with dark skin as more skin pigments like melanin reduces the ability of the skin to produce vitamin D.
  • People with fat malabsorption conditions such as Crohn’s disease, cystic fibrosis, liver and celiac disease or patients who have undergone surgical removal of any part of the stomach or intestine.
  • People who are obese. An increased amount of subcutaneous fat can snatch more of the vitamin D and somehow alter its release in the circulation.

Interaction of Vitamin D with Prescribed Drugs

Vitamin D supplements have the tendency to react with certain types of prescription medications. These include the following:

  • Steroids or corticosteroid medications like prednisone which can cause decreased calcium absorption and also damage the vitamin D metabolism process.
  • Weight-loss medications such as orlistat and cholesterol-lowering drugs like cholestyramine also decrease the absorption of vitamin D and other fat-soluble vitamins.
  • Phenobarbital and phenytoin increases vitamin D metabolism and decreases calcium absorption.
