The Active Ingredient Is: Vitamin B3 (Niacin) inositol hexanicotinate

Vitamin B3, or what people call niacin, is a water-soluble B vitamin. Inositol hexanicotinate is a type that ties six niacin units to one inositol molecule, allowing slow release in your body.

This version delivers the active niacin element via a complex built to minimise flushing while sending the essential nutrient from a natural carrier.

What Does Vitamin B3 Do?

Vitamin B3 helps with energy production and fat metabolism and supports DNA repair and other cellular processes, in line with EFSA and NHS functional insights.

The slow-release form is metabolised to release niacin gradually, helping normal physiological functions linked to the vitamin’s coenzyme roles in the body.

This supplement is not intended to diagnose, treat, cure, or prevent any disease.
