Vitamin B6 is essential for healthy skin and a normal functioning immune system. It is a natural antihistamine with the ability to reduce histamine intolerance (along with vitamin C), making it helpful for people with allergies and histamine intolerance. Vitamin B6 helps the liver detoxify chemicals and it can reduce the toxic effects of salicylates, benzoic acids, food preservatives, monosodium glutamate (MSG), alcohol and heavy metals. Vitamin B6 is essential for normal fat metabolism and, as a result, a deficiency in vitamin B6 can raise cholesterol levels and cause fatty liver. Vitamin B6 is also important in the metabolism of protein. It has been linked to helping morning sickness in pregnant women.
