Vitamin C was first discovered in 1928 by a Nobel Prize winner Albert von Szent-Györgyi.

Vitamin C is the most well-known and popular vitamin needed for the proper course of many life processes. The largest amounts are found in organs with high metabolic acitvity, including in the adrenal glands, brain, pancreas, stomach and lungs.

The minimum daily requirement for vitamin C is the largest of all the vitamins. It is about 1 mg/kg of body weight in an adult, and approximately 2 mg/kg of body weight in infants and children. The daily requirement for vitamin C increases in pregnant and breastfeeding women (to about 1.5 mg/kg of body weight) and in various medical conditions (arterial hypertension, diabetes mellitus, in patients on renal dialysis), as well as in smokers and in people who are under stress. It is also increased after strenuous, long-lasting physical activity, and in the case of vomiting, lack of appetite and abnormal bowel function.

Due to lack of enzyme L-gulonolactone oxidase, the human body is unable to produce vitamin C on its own and must get it from food and/or supplementation.
