The Active Ingredient Is: Niacin (Vitamin B3)

Niacin is a water-soluble B vitamin that offers a central role in cellular energy production and metabolic processes.

This form is shown as part of a B complex blend, with niacin contributing to its overall profile of essential B vitamins for energy and nervous system support.

What Does Niacin Do?

Niacin is involved in energy metabolism and supports normal function of the nervous system, in line with EFSA guidance and NHS information on B vitamins.

Evidence from researchers at the University of Cambridge suggests niacin contributes to energy production processes and nerve health through its metabolic roles, reinforcing its place within a comprehensive B vitamin profile.
