What does it do?

Niacin is a water-soluble vitamin that belongs to the vitamin B3 group. It primarily participates in energy production in the body and the metabolism of fats, carbohydrates, and proteins, and it is used in pharmaceuticals to prevent or supplement vitamin deficiency.

Niacin is converted in the body into important coenzymes such as nicotinamide adenine dinucleotide (NAD) and NAD phosphate (NADP), playing an essential role in energy metabolism. This helps cells to function normally and facilitates metabolic processes.

Approved uses differ by product. Check each product's information for its actual use.

Good to know

Unlike other forms of vitamin B3 such as nicotinamide, niacin has a vasodilatory effect, which may sometimes cause flushing of the skin. However, in pharmaceuticals, it is primarily used for vitamin supplementation and is often administered in combination with other B vitamins.
