The Active Ingredient Is: Vitamin B3 (Niacinamide)

Vitamin B3, or niacinamide, is a water-soluble vitamin that’s essential for cellular energy and overall health. This version is the no-flush kind and comes in vegetarian capsules, free from common allergens.

This no-flush version of B3 comes in a hypromellose capsule suitable for vegetarian use.

What Does Vitamin B3 Do?

Niacinamide acts as a precursor to NAD+, a crucial coenzyme involved in cell energy production and DNA repair. It also supports antioxidant function and helps regulate inflammatory responses, contributing to normal cellular health.

Dr. Maiese of Johns Hopkins University found that niacinamide contributes to these core cellular roles, reflecting its role in energy metabolism and protective cellular processes.
