The Active Ingredient Is: Vitamin C (Calcium Ascorbate)

Vitamin C, also known as ascorbic acid, is a water-soluble nutrient that supports normal collagen formation and antioxidant protection. This product uses calcium ascorbate, a buffered form that is pH-neutral and gentler on the stomach while maintaining absorption.

This buffered Vitamin C contains calcium ascorbate for buffering, and there are added bioflavonoids and acerola powder to amplify antioxidant activity and support sustained bioactivity.

What Does Vitamin C Do?

Vitamin C helps support antioxidant defence and collagen synthesis to maintain skin, bone, and connective tissue health, while also supporting immune function in line with EFSA guidance.

In this formulation, the combination of Vitamin C with bioflavonoids and acerola enhances the antioxidant capacity and helps maintain normal physiological functions without promoting disease claims.
