Vitamin B6 is a water-soluable vitamin which comes in three forms: pyridoxine, pyridoxal, and pyridoxamine.
B-6 has a wide variety of metabolic functions in the body, especially in amino acid metabolism and in the central nervous system. Vitamin B6 is a factor in the conversion of amino acids to carbohydrate or fat, and in fat metabolism.
Vitamin B6 plays a vital role in many different aspects of the immune system, including the quality and quantity of antibodies and the number of infection-fighting white blood cells and the formation of red blood cells.
Vitamin B6 is important in maintaining healthy hair and skin.
Vitamin B6 is effective in relieving some of the symptoms of PMS, including depression, breast tenderness and bloating.
Clinical signs of B6 deficiency are rarely seen in the United States; however, the signs are:
- Skin disorders
- Kidney stones
Too much vitamin B6 can result in nerve damage to the arms and legs. This neuropathy is usually related to high intake of vitamin B6 from supplements, and is reversible when supplementation is stopped. According to the Institute of Medicine, "Several reports show sensory neuropathy at doses lower than 500 mg per day". The Food and Nutrition Board of the Institute of Medicine has established an upper tolerable intake level (UL) for vitamin B6 of 100 mg per day for all adults. "As intake increases above the UL, the risk of adverse effects increases."
Folate and Vitamin B6 Reduce the Risk of Cardiovascular Disease
Researchers from the graduate school of medicine in Osaka, Japan used a food frequency questionnaire to conduct a prospective cohort study of 58,730 Japanese adults over 14 years. It was found that there was an inverse relationship between folate and vitamin B6 intake with mortality from heart failure for men and mortality from stroke, coronary heart disease and total cardiovascular disease for women.
