Product Description : 

Vitamin C (also known as ascorbic acid and ascorbate) is a water-soluble vitamin found in citrus and other fruits, berries and vegetables, also sold as a dietary supplement and as a topical "serum" ingredient to treat melasma (dark pigment spots) and wrinkles on the face. It is used to prevent and treat scurvy. Vitamin C is an essential nutrient involved in the repair of tissue, the formation of collagen, and the enzymatic production of certain neurotransmitters. It is required for the functioning of several enzymes and is important for immune system function. It also functions as an antioxidant. Most animals are able to synthesize their own vitamin C. However, apes (including humans) and monkeys (but not all primates), most bats, most fish, some rodents, and certain other animals must acquire it from dietary sources because a gene for a synthesis enzyme has mutations. 

Vitamin C may be taken by mouth or by intramuscular, subcutaneous or intravenous injection. Other than for treating scurvy, which is a vitamin C deficiency caused disease, there are a number of diseases and health conditions for which claims have been made for increased risk if moderately deficient, and for benefits from vitamin C supplementation in excess of recommended dietary consumption for people who are not considered vitamin C deficient. The long history of claimed benefits includes the common cold, cancer, heart disease and COVID-19. 

Vitamin C is generally well tolerated. Normal doses are safe during pregnancy. Large doses may cause gastrointestinal discomfort, headache, trouble sleeping, and flushing of the skin, and the United States Institute of Medicine recommends against consuming large amounts. 

Vitamin C was discovered in 1912, isolated in 1928, and in 1933, the first vitamin to be chemically produced. It is on the World Health Organization's List of Essential Medicines. Vitamin C is available as an inexpensive generic and over-the-counter medication. In 2021, it was the 255th most commonly prescribed medication in the United States, with more than 1 million prescriptions. Partly for its discovery, Albert Szent-Györgyi and Walter Norman Haworth were awarded the 1937 Nobel Prizes in Physiology and Medicine and Chemistry, respectively.
