The Key Ingredient Is: Niacinamide (Vitamin B3)

Niacinamide is a water-soluble version of the B vitamin niacin, essential for cellular energy and DNA stability.

This form is supplied as niacinamide in a vegetarian capsule and is described as supporting energy production and keeping DNA integrity through its conversion to key coenzymes.

What Does Niacinamide Do?

Niacinamide participates in energy metabolism by forming NAD, NADH, NADP, and NADPH, which are involved in cellular energy pathways. It also supports DNA maintenance, a function noted in research on UV-exposed skin. This information is aligned with EFSA and NHS-style guidance on normal energy and DNA-related processes.

Dr. Surjana of the University of Melbourne found that oral niacinamide can enhance DNA repair in UV-damaged skin, illustrating a protective cellular mechanism.
