The Active Ingredient Is: Vitamin C (Ascorbic Acid)

Vitamin C, or ascorbic acid, is a water-soluble nutrient essential for ordinary bodily functions including collagen formation and immune support.

This form is L-ascorbic acid, a pure, quick-dissolving dietary supplement ingredient often used to support daily vitamin C intake.

What Does Vitamin C Do?

Vitamin C participates in collagen formation and contributes to the normal function of the skin, blood vessels, bones, cartilage, gums and teeth, as recognised by EFSA. It also supports antioxidant defence and iron absorption as part of normal physiology.

Dr. Hemilä from the University of Helsinki reported that vitamin C can reduce the duration and severity of common colds in some populations, illustrating a potential everyday immune-boosting benefit.
