Ingredients & DescriptionVitamin B6 (Pyridoxine) is involved in the formation of body proteins and structural compounds including chemical transmitters in the brain. Vitamin B6 is also critical in maintaining hormonal balance and proper immune function. Vitamin B6 is involved in nearly 60 enzyme systems in the body. It is necessary for normal growth, red blood cell synthesis and vitamin B12 absorption. Vitamin B6 supplementation, in conjunction with folic acid and vitamin B12, can lower homocysteine levels. By inhibiting the production of oxalate, vitamin B6 may prevent calcium oxalate kidney stone recurrence. Persons at risk for vitamin B6 deficiency are: anyone with a malabsorption problem (such as lactose intolerance or celiac disease); diabetics; elderly; women who are pregnant, nursing or taking oral contraceptives.
