The Active Ingredient Is: Vitamin C (Ascorbic Acid)

Vitamin C is a water-soluble nutrient and a potent antioxidant essential for normal bodily functions. This buffered formulation delivers vitamin C in a form that is designed to be gentler on the stomach due to mineral buffering.

The buffered powder includes minerals to offset acidity, which helps improve palatability and tolerability when consumed as a high-potency supplement.

What Does Vitamin C Do?

Vitamin C contributes to normal collagen formation and supports normal immune function, in line with EFSA guidance. It also supports normal energy metabolism and the protection of cells from oxidative stress as a key antioxidant role.

EFSA recognises vitamin C as contributing to collagen formation and immune function, while the buffering minerals help maintain tolerability of high-dose vitamin C.
