The Active Ingredient Is: Vitamin C (Ascorbic Acid)

Vitamin C, also called ascorbic acid, is a water-soluble vitamin essential for everyday body functions and antioxidant protection. This product uses Q-C ascorbic acid, a high-purity form made in Scotland for reliability and vegan suitability.

This formulation uses a vegan, non-GMO, gluten-free capsule as the carrier, with vitamin C as the sole active ingredient and no extra active formulation ingredients.

What Does Vitamin C Do?

Vitamin C helps support immune system function and provides antioxidant protection, while aiding connective tissue formation and collagen synthesis in line with EFSA and NHS guidance. It supports normal functioning of skin, cartilage, bones, and teeth.

Dr. Carr from Harvard University found that vitamin C contributes to immune defence by supporting diverse cellular functions of both innate and adaptive immune systems.
