Vitamin C

Vitamin C, or ascorbic acid, is also a water-soluble vitamin that participates in the body in the formation of tissues and teeth. It also acts in the body as an antioxidant, i.e. it protects the body against detrimental oxidation caused by free radicals.
Vitamin C is obtained from fruit, berries and vegetables. Deficiency of vitamin C may cause tiredness and susceptibility to infections. As a disease, vitamin C deficiency is referred to as scurvy.

Energy drinks contain ca. 30 mg of vitamin C per 100 ml, which is half of the recommended daily intake.
