The Active Ingredient Is: Vitamin C (Ascorbic Acid)

Vitamin C is a water‑soluble vitamin that's essential for normal body functions like collagen building and antioxidant protection. This formula keeps Vitamin C in a buffered, mixed-ascorbate form to help with tolerability and bioavailability.

This mix pairs ascorbic acid with calcium, potassium and magnesium ascorbates to be gentler for sensitive folks and to support antioxidant activity in a balanced mineral setup.

What Does Vitamin C Do?

Vitamin C helps keep the immune system running and supports collagen production as part of normal processes, with evidence backing its role in immune function and connective tissue health.

In line with EFSA expectations, this nutrient contributes to antioxidant protection and supports normal energy release and tissue integrity through its part in collagen synthesis and cellular defence.

Dr. Hemilä of University of Helsinki found that daily vitamin C supports immune function and collagen production, backing the nutrient’s established roles.
