Vitamin C is involved in numerous redox reactions in the human body as an antioxidant and cofactor, which means it influences numerous processes such as antioxidant cell protection, the immune system and energy metabolism. It is also involved in the formation of the structural protein collagen (skin, cartilage, bones, blood vessels) and the synthesis of hormones.
Higher concentrations of vitamin C are naturally found in fresh fruit, vegetables and berries such as camu camu, sea buckthorn berries, acerola cherries, rose hips, blackcurrants, kale, parsley, kiwis and citrus fruits.
Vitamin C is still the subject of intensive research. New mechanisms of action of this fascinating vitamin are discovered almost every year. The following statements on vitamin C have so far been authorised by the EU.
According to the European Food Safety Authority (EFSA):
Vitamin C contributes to...
- The reduction of tiredness and fatigue
- Normal mental function
- The regeneration of the reduced form of vitamin E
- Normal energy metabolism
- Normal immune system function
- The normal function of the nervous system
- Protecting cells against oxidative stress
- Normal collagen formation for normal blood vessel function
- Normal collagen formation for normal bone function
- Normal collagen formation for normal cartilage function
- Normal collagen formation for normal dental function
- Normal collagen formation for normal gum function
- Normal collagen formation for normal skin function
- Increasing iron absorption
- Maintaining normal immune system function both during and after intense physical activity
