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.*

B-complex vitamins are needed by the body for energy production, synthesis of blood cells, healthy nervous system function, and countless other metabolic processes.* The forms of the B vitamins found in foods and most supplements, however, require conversion into their active forms before they can perform their functions as co-factors in biochemical reactions.* NOW^® Co-Enzyme B-Complex contains B vitamins in their active or “co-enzyme” forms.

Folic acid is a very important member of the B-vitamin family required for DNA synthesis and genetic repair, making an adequate supply essential for rapidly dividing cells, such as red blood cells.* Folic acid is also necessary for the synthesis of methionine from homocysteine and can help to contribute to the healthy function of both the cardiovascular and nervous system.*

From the FDA: “0.8 mg folic acid in a dietary supplement is more effective in reducing the risk of neural tube defects than a lower amount in foods in common form. FDA does not endorse this claim. Public health authorities recommend that women consume 0.4 mg folic acid daily from fortified foods or dietary supplements or both to reduce the risk of neural tube defects.”

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).

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.

This product has twice the niacin (500 mg per capsule) as in our regular strength product (250 mg per capsule).

Pantothenic Acid (Vitamin B-5) is a member of the B-complex family of vitamins and is found in nearly every living cell as a component of coenzyme A (CoA).* CoA is essential for the generation of energy from fat, carbohydrate, and protein.* It also plays a critical role in many biosynthetic reactions as well, being necessary for the production of fats, cholesterol, neurotransmitters, red blood cells, and adrenal secretions.* As such, pantothenic acid is vital for countless cell functions and the maintenance of healthy cellular metabolism.*

B-100 Caps provide a full complement of B-vitamins plus choline and inositol. These vitamins work to support energy production, maintain healthy homocysteine metabolism, and promote the health of the nervous system.* B-vitamins are water soluble, and with the exception of B-12, have limited storage in the body and thus require daily replenishment. While B-12 is stored in the liver, dietary sources are of animal origin only (meat and dairy) and supplementation with B-12 may be especially important for vegetarians.

B-50 Tabs provide a full complement of B-vitamins plus choline and inositol. These vitamins work to support energy production, maintain healthy homocysteine metabolism, and promote the health of the nervous system.* B-vitamins are water soluble, and with the exception of B-12, have limited storage in the body and thus require daily replenishment. While B-12 is stored in the liver, dietary sources are of animal origin only (meat and dairy) and supplementation with B-12 may be especially important for vegetarians.
