For more and more people, a healthy and balanced diet means an important, active contribution to health and enjoyment of life. This also includes strengthening the immune system. To counteract a lack of vitamins and minerals, many consumers take advantage of dietary supplements, especially at the beginning of fall and winter.

Probably one of the best known dietary supplements is vitamin C. In food, vitamin C is found mainly in fruits and vegetables. Citrus fruits such as oranges and lemons or even various types of cabbage contain a lot of vitamin C. Organic ascorbic acid is a colorless and odorless, easily water-soluble crystalline solid with an acidic taste. Its salts are called ascorbates. Due to its biological activity, L-(+)-ascorbic acid used in preparations for food supplements. L-(+)-ascorbic acid and also its derivatives, having the same effect, are called vitamin C.

But it is not always possible to cover the need for nutrients and vitamins through food alone. Food supplements therefore remain a useful complement for the supply of essential building blocks.

Vitamin C contributes to a healthy diet and has an important positive influence on a variety of bodily functions.

Among others, it contributes to:

  • a normal function of the immune system
  • a normal collagen formation for a normal function of the blood vessels
  • a normal collagen formation for a normal function of bones
  • a normal collagen formation for a normal function of skin
  • a normal energy metabolism
  • a normal function of the nervous system
  • reduce fatigue and tiredness

All applicable health claims for vitamin C can be found in Commission Regulation 432/2012.
