Vitamin C, collagen and your skin

With a 30% share of total body protein, collagen is the most abundant protein in the human body. Collagen is the most important structural protein of the skin and fulfills a variety of functions to maintain its elasticity and flexibility. From around the age of 25, the body's collagen production drops and also slows down with age. The elasticity of the skin decreases, wrinkles and connective tissue weaknesses such as cellulite develop.

Vitamin C is not only a basic requirement for the body's own collagen production, but also a stimulant. This is shown by scientific studies on human skin fibroblasts in which it could be shown that long-term treatment with vitamin C for 5 days significantly improves the synthesis of collagen I and IV [1].

Like vitamin E, vitamin C helps protect the cells from oxidative stress. While vitamin E loses its antioxidant effect in preventing cell attack, vitamin C has the capacity to regenerate the reduced form of vitamin E. Accordingly, when combined, vitamins C and E are particularly effective in protecting cells from free radicals

To a certain extent, this age-related collagen breakdown - also due to increasing environmental influences - can be counteracted with a healthy lifestyle, e.g. through high-dose vitamin C and special superfood nutrients as a dietary supplement.
