Ascorbic Acid is used in a very large number of different product types, from health supplements to skincare and cosmetics. E300 can also be found in food stuffs like bread, fruit juice, and even cured meats. Vitamin C occurs naturally in many fruits and vegetables like broccoli, citrus (oranges, lemons, etc), strawberries, red peppers and more.

The first ever method to make Ascorbic Acid is called the Reichstein Process. It was developed in 1933 by Nobel Prize winner Tadeusz Reichstein. It involves converting D-Sorbitol into L-Ascorbic Acid with the help of a microbial culture (Gluconobacter oxydans). Nowadays, a much cheaper, more energy-efficient, safer and simpler method is used to generate much higher yields of vitamin C. It also employs the assistance of microorganisms (in this case Ketogulonicigenium vulgare and Bacillus spp.).

The Recommended Daily Allowance (RDA) for vitamin C is just 75-90 mgs a day for adults but many experts suggest that supplementing with around 500 mgs a day for adults is the best way to achieve its health results.
