Vitamin B6 Fattening? Full Review

Vitamin B6 Fattening? Full Review / Supplements

Vitamin B6, also called pyridoxine, is a water-soluble vitamin that is consumed through certain types of food and is essential for various body processes. Vitamin B6 is fattening, not directly, but it plays an indirect role in weight gain. This can occur in people with vitamin B6 deficiencies. Vitamin B6 deficiency is more common in the elderly, alcoholics, asthmatic children, and people who have a poor diet.


Vitamin B6 serves multiple purposes in the human body. It helps the immune system produce antibodies to fight diseases and infections. It also helps the nervous system to maintain proper functioning and has a role in the release of serotonin in the brain. Serotonin is important for the general well-being of a person and for the feeling of joy. Vitamin B6 is also involved in the process of protein synthesis - protein breakdown - so people who eat too much protein also need a greater amount of Vitamin B6 in their diets.


Vitamin B6 is found in many different types of foods. Fortified morning cereal is one of the foods with the highest concentration of vitamin B6, offering about 2 mg per serving. Other foods that contain a relatively high concentration of vitamin B6 are potato, banana, chicken breast, fish and sunflower seeds. Vitamin B6 supplementation is not necessary for most healthy people who follow a balanced diet; your doctor may suggest whether or not you should use a supplement.

Daily Recommendation

The National Institutes of Health recommends that infants consume 0.1 mg per day until 7 months of age, when the daily recommendation increases to 0.3 mg. Children between 1 and 13 years old need 0.5 to 1 mg. Most adults of adolescents should consume 1.3 mg per day. Men over age 50 need 1.7 mg per day and women in the same age group need 1.5 mg per day. For reference, a single banana contains 0.68 mg, and a potato contains 0.70 mg of vitamin B6.

In what situation is vitamin B6 fattening?

Excess vitamin B6 is eliminated from the body through the urine, so consuming too much vitamin B6 is not a big risk. However, it is possible to damage nerve cells in the arms and legs when you consume 500 mg of vitamin B6 or more per day. Vitamin B6 deficiency can lead to depression in some people due to the effect on serotonin levels. An MIT study linked depression to weight gain. So, indirectly, vitamin B6 deficiency becomes fat because of depression.
