The Active Ingredient Is: Vitamin C (L-ascorbate)

Vitamin C, or L-ascorbate, is a water soluble vitamin that provides antioxidant protection and supports connective tissue formation in the body.

This fully buffered L-ascorbate form includes mineral cofactors such as potassium, calcium, magnesium and zinc to support absorption and tissue action, and is prepared through triple recrystallisation under nitrogen to preserve potency and reduce oxidation.

What Does Vitamin C Do?

Vitamin C plays a role in antioxidant protection and supports collagen synthesis, hormone production and immune function as recognised in EFSA guidance.

This formulation emphasises a fully reduced, buffered vitamin C form that may enhance stability and bodily availability, aligning with general nutritional science on vitamin C functions.
