The Active Ingredient Is: Vitamin C (Ascorbic Acid)

Vitamin C, also known as ascorbic acid, is a water-soluble vitamin essential for normal physiological function and overall health support.

This form is the widely used ascorbic acid in dietary supplements, providing a bioavailable source that supports immune function within everyday health routines.

What Does Vitamin C Do?

Vitamin C contributes to the normal function of the immune system and helps support white blood cell activity, in line with EFSA guidance on vitamin C functions.
