The Active Ingredient Is: Vitamin C (Ascorbic Acid)

Vitamin C, also known as ascorbic acid, is a water-soluble micronutrient essential for everyday bodily function and skin vitality because of its job as an antioxidant and a collagen formation cofactor.

This supplement uses a concentrated ascorbic acid form aimed at solid bioavailability and purity, in line with pharmaceutical-grade standards. The mix puts Vitamin C front and centre as the main active nutrient, with other ingredients not shown as active components.

What Does Vitamin C Do?

Vitamin C helps shield cells from oxidative stress and contributes to normal collagen formation, supporting skin and connective tissue health. It also helps with iron absorption and supports immune function as part of everyday immune system activity.

Dr. Carr from Harvard University notes that Vitamin C contributes to immune defence and antioxidant protection, aligning with recognised nutrient functions and EFSA-consistent claims.
