Vitamin C, also known as ascorbic acid, is a crucial nutrient for various bodily functions. Unlike some vitamins, our bodies cannot produce vitamin C, making it essential to obtain it through diet or supplements. This article explores the recommended intake, health benefits, rich food sources, and signs of vitamin C deficiency.
Why is Vitamin C Important?
Vitamin C plays a vital role in numerous bodily processes:
- Collagen Production: It’s essential for synthesizing collagen, a protein crucial for skin, bones, cartilage, and blood vessels.
- Antioxidant Powerhouse: Vitamin C acts as a potent antioxidant, protecting cells from damage caused by free radicals.
- Immune System Support: It strengthens the immune system by promoting white blood cell function and aiding in wound healing.
- Iron Absorption: It enhances the absorption of non-heme iron, the type found in plant-based foods.
How Much Vitamin C Do You Need?
The Recommended Dietary Allowance (RDA) for adults is 90 mg daily for men and 75 mg for women. Smokers need an additional 35 mg daily. The Tolerable Upper Intake Level (UL) is 2000 mg. Exceeding this limit can cause digestive issues.
Health Benefits of Vitamin C-Rich Foods
While megadoses of vitamin C haven’t proven to prevent colds, consuming adequate amounts through foods offers various benefits:
Chronic Disease Prevention
Studies suggest a link between higher vitamin C intake from fruits and vegetables and a reduced risk of cardiovascular disease and certain cancers.

Gout Management
Research indicates that vitamin C may lower uric acid levels in the blood, potentially reducing the risk of gout.
