Q:

What are the health benefits of vitamin B6?

Quick Answer

Vitamin B6 promotes the proper functioning of the cardiovascular, immune, nervous, muscular and digestive systems, according to Everyday Health.

Vitamin B6 may play an important role in the creation of serotonin and dopamine, two chemicals responsible for proper nerve communication, according to Everyday Health. Therefore, B6 may be beneficial for neurological conditions, such as Parkinson's Disease, seizures, depression and chronic pain.

A lack of sufficient B6 may contribute to an increased risk of heart disease. The results of a large study in Japan demonstrate that high consumption of vitamins B6 and B12 reduces the risk of death from heart failure, coronary artery disease and stroke. However, a Duke University study shows that although B6 seems to reduce the risk of stroke and macular degeneration, there is not adequate evidence that B6 delays cardiovascular disease or age-related cognitive changes. Everyday Health gives daily intake recommendations and states that adults should consume no more than 100 milligrams per day of vitamin B6.
