The Core Ingredient Is: Vitamin C (Ascorbic Acid)

Vitamin C, which you might know as ascorbic acid, is a water soluble vitamin essential for building connective tissue and keeping immunity in check.

This form is ascorbic acid and is there to give a stable, food grade source of vitamin C for easy daily use.

What Does Vitamin C Do?

Vitamin C helps to support antioxidant networks by helping the regeneration of other antioxidants and contributes to collagen formation, which is important for normal tissue function. It also helps the body’s defence against oxidative stress as part of a balanced antioxidant system.

EFSA notes the antioxidant role of vitamin C and its involvement in supporting normal physiological functions related to connective tissue and immune support.
