Application

High quality Vitamin C was used for preventing and treating scurvy in the past. Today, people most commonly use vitamin C for preventing and treating the common cold. It's also used for autism, breast cancer, heart disease and many other conditions, but there is no good scientific evidence to support many of these uses. There is also no good evidence to support using vitamin C for COVID-19.
