Pyridoxine (B6)

This vitamin helps to regulate levels of circulating homocysteine along with two other B vitamins folate and cobalamin – note that higher levels of homocysteine in the blood has been associated with increased risk of heart disease and stroke.


Biotin (B7)

This vitamin is needed to properly and efficiently metabolize carbohydrates, fats, and proteins. This vitamin is best known for its positive effects on skin, hair, and nails.
