The Active Ingredient Is: Niacin (Vitamin B3, Nicotinic Acid)

Niacin, also known as vitamin B3, is a water-soluble nutrient involved in normal energy metabolism and cellular function. This form is nicotinic acid, commonly used in supplements to support energy-related processes in the body. Niacin contributes to energy production and supports metabolic health.

What Does Niacin Do?

Niacin plays a role in energy release and is involved in normal carbohydrate metabolism, contributing to overall metabolic function. This supports general well-being as described in EFSA- and NHS-aligned guidance. Dr. Shiel Jr. of Harvard University found that niacin can raise HDL cholesterol and modestly lowers triglycerides.

Dietary supplements are not a replacement for a balanced diet. Do not take more than the recommended amount. Keep in a cool, dry area away from light and heat. Ensure they are out of children's reach and view.
