The Active Ingredient Is: Vitamin C (Ascorbic Acid)

Vitamin C, or ascorbic acid, is a water-soluble nutrient basically essential for everyday body function and connective tissue health.

This form of the nutrient is usually sourced as ascorbic acid and is widely recognised for its role as an antioxidant and its part in collagen formation and skin health.

What Does Vitamin C Do?

Vitamin C helps support normal immune function and protection of cells from oxidative stress, as supported by EFSA guidelines and NHS information. It also involved in collagen synthesis, supporting skin and connective tissue health.

Research from Carr at the University of Milan backs these roles, highlighting vitamin C's antioxidant function and involvement in immune-related processes as part of normal physiology.
