Niacin is a member of the Vitamin B family. It is sometimes referred to as Vitamin B3. The term niacin is a collective term referring to both nicotinic acid and niacinamide. Both nicotinic acid and niacinamide have identical vitamin activities, but very different pharmacological activities.
Niacin is involved in a wide range of biological processes including the production of energy, the synthesis of fatty acids, cholesterol, and steroids, signal transduction, the regulation of gene expression, and the maintenance of gene integrity. In pharmacology, nicotinic acid is used as an anti-hyperlipidemic agent. Both nicotinic acid and niacinamide are efficiently absorbed through the stomach and small intestine. However, they are metabolized differently and excreted in the urine in different forms.
We use niacinamide in our recommendations to avoid side effects often associated with nicotinic acid such as flushing. Nicotinic acid causes vasodilatation within twenty minutes of ingestion which can last for up to an hour.
