Vitamin C

Vitamin C (ascorbic acid) is perhaps one of the most well-known vitamins. And that's not surprising, as it plays a significant role in many processes in your body, including supporting collagen production. Vitamin C is water-soluble – this means that your body does not store it, but immediately excretes any excess vitamin C. Therefore, it is important to consume it regularly. How much vitamin C do you need, how can you ensure an adequate intake, and what else do you need to know about it?
