Biotin is a water-soluble vitamin necessary for normal growth and body function.* Biotin functions as a key regulatory element in gluconeogenesis, fatty acid synthesis, and in the metabolism of some amino acids.* Alongside its role in energy production, biotin enhances the synthesis of certain proteins.* In addition, biotin promotes healthy immune system function and plays a critical role in skin health.*

Niacin (vitamin B-3) is an essential B-complex vitamin. Flush-free niacin contains inositol hexanicotinate, a form of niacin that consists of six molecules of niacin linked to a single inositol molecule. It is slowly broken down in the body to yield free niacin and inositol. This gradual release of niacin allows for true niacin activity without the characteristic niacin flush that many people cannot tolerate.

Inositol is a non-essential member of the B-complex family with dietary sources from both animal and plant foods. The form of inositol used in this product is myo-inositol, the most abundant form of this nutrient. Inositol is found in all cell membranes, with the highest concentrations in the brain and central nervous system, where it plays an important role in neurotransmitter signaling.* Inositol is also critical for the proper action of insulin, lipid metabolism, and for the maintenance of cellular calcium balance.*

Vitamin B-12 is necessary for the production of energy from fats and proteins and is well known for its critical role in DNA synthesis, as well as in homocysteine metabolism.* Methylcobalamin is the co-enzyme form of vitamin B-12 that has been found to be especially critical in the maintenance of a healthy nervous system.* Dietary sources are almost exclusively of animal origin (meat and dairy) and supplementation with B-12 may be especially important for strict vegetarians. NOW^® Methyl B-12 is vegetarian/vegan (non-animal derived).
