The Active Ingredient Is: Vitamin B3 (Niacin)

Vitamin B3, also known as niacin, is a water-soluble nutrient essential for energy metabolism and cellular function. This sustained-release form provides gradual release to support daytime metabolic processes while minimising rapid blood level changes.

This formulation uses a sustained-release niacin tablet to deliver the active ingredient and minimise flushing, while remaining suitable for adult use under medical supervision.

What Does Vitamin B3 Do?

Vitamin B3 participates in energy production and supports nervous system and skin health, in line with EFSA and NHS guidance.

Dr. Johnson of Stanford University found that niacin acts as a precursor to NAD, a key molecule in cellular energy and DNA repair, underlying its role in metabolism and overall cellular function.
