What is vitamin C?

Vitamin C (ascorbic acid) is a water-soluble vitamin that plays an important role in our immune system, as cell protection, in collagen synthesis and in the absorption of iron. It supports the production of hormones and messenger substances, influences our mood, ensures good wound healing and healthy blood vessels.

Vitamin C is absorbed in the intestine by specific transport proteins. Genetic variations can influence the transporters and the absorption of vitamin C in the body.

A vitamin C deficiency manifests itself in frequent infections, fatigue, exhaustion, wound healing disorders, dental problems and depressive moods.
