Vitamin B6, or pyridoxine, is an important component of the coenzyme PLP, which metabolizes amino acids. Because of its amino acid transfer ability, the body can produce non-essential amino acids from available amino groups, as well as metabolize protein and urea. Vitamin B6 is essential because of its participation in more than 140 enzymatic reactions, including protein metabolism, conversion of tryptophan to niacin, and neurotransmitter function, among others.

Found in foods such as eggs, brewer’s yeast, carrots, chicken, fish, brown rice, whole grains, and cabbage, vitamin B6 (along with B12 and folic acid) plays a beneficial role in maintaining already healthy homocysteine levels within normal range.
