Vitamin C is a water-soluble nutrient that plays several roles in normal body function. According to the U.S. National Institutes of Health Office of Dietary Supplements, vitamin C acts as an antioxidant, supports collagen formation, helps with the absorption of iron from plant-based foods, and contributes to normal immune function.
Start with food first
Fruits and vegetables are the main dietary sources of vitamin C. Citrus fruits, peppers, kiwifruit, broccoli, strawberries, potatoes, and tomatoes are all examples of foods that can contribute vitamin C to the diet.
When might a supplement fit?
Many people can meet their vitamin C needs through food. A supplement may be something to consider when dietary intake is limited or when a person has been advised to use one. The right amount depends on age, diet, health status, and other factors, so it is important to follow the product label and seek professional advice when appropriate.
