The Active Ingredient Is: Vitamin C (Ascorbic Acid)

Vitamin C, or ascorbic acid, is a water-soluble micronutrient crucial for healthy connective tissue and immune function.

This formulation uses Quali-C ascorbic acid manufactured in Scotland, giving pharma-grade purity with no fillers or extras.

What Does Vitamin C Do?

Vitamin C helps support immune function and provides antioxidant protection in line with EFSA guidelines, contributing to the normal functioning of the body's defence systems.

It also acts as a cofactor in collagen synthesis, supporting connective tissue integrity in skin, joints, and blood vessels, and it aids iron absorption, with roles recognised in general nutritional guidance.

This supplement is not intended to diagnose, treat, cure, or prevent any disease.
