Most higher organisms form it by way of glucuronate. Only humans, some primates, birds and guinea pigs have lost the ability to self-synthesise ascorbic acid. For them, the natural substance is a vitamin and must be supplemented through food.


Functions of vitamin C

The biochemical meaning of vitamin C is based on its property as a redox system:

  • Antioxidant protection factor. Vitamin C is the most important antioxidant system in the aqueous phase of the somatic cells and contributes towards protecting the cells against oxidative stress. It also contributes to the regeneration of the reduced form of vitamin E.
  • Immune activator. Immune cells are particularly sensitive to vitamin C. Vitamin C plays a part here in the normal function of the immune system. It also helps to maintain the body's defence during and after intense activity. However, this required a vitamin C intake of at least 200 mg per day.
  • Collagen synthesis. Vitamin C is essential for the normal formation of collagen and thus supports the normal function of the bones, cartilage, teeth and gums as well as the skin and blood vessels.
  • Energy metabolism. Vitamin C also plays a part in the normal energy metabolism and contributes to the reduction in tiredness and fatigue.
  • Nervous system. Vitamin C contributes towards the normal function of the nervous system and the normal mental function.
  • Resorption of iron. Vitamin C improves the availability of iron from plant-based foods. This is of particular interest for people with a vegetarian diet.


Useful information.

  • As an antioxidant protective factor, vitamin C works closely with vitamin E, ubichinol (coenzyme Q10) and α-lipoic acid.
  • Vitamin C is particularly sensitive to heat, oxygen and light. Losses of up to 100 % are to be expected in storage and preparation.


Information on production technology

  • Single doses of vitamin C ≥ 200 mg are absorbed by the body to a limited extent. To increase the bioavailability, INTERCELL Pharma uses pellets with a retard effect for product concepts with higher vitamin C quantities. In this way, the vitamin C is slowly released over a time period of around 8 hours. This provides a particularly good bioavailability even with a higher vitamin C intake.
