Foods Rich in Vitamin C

Vitamin C is mostly known for its effects on the immune system. It is an antioxidant and contributor of collagen synthesis. Vitamin C also helps with the absorption of iron so consuming them together improves their intake in the body. The recommended intake (RDA) for adults is between 75-90 mg/day. Smoking and alcohol affect vitamin utilization so increased intake is needed. Although studies have been done to show possible benefits from vitamin C pills, there is still debate on their efficacy so consuming natural forms is your best bet.
