What Is Vitamin C?
Vitamin C, also known as ascorbic acid, is an essential nutrient that is abundant in many fruits and vegetables. This vital nutrient is involved in several functions within the body, including supporting the immune system, aiding in collagen production, improving wound healing, and enhancing nutrient absorption. While citrus fruits are commonly associated with vitamin C, other foods, such as bell peppers, broccoli, kiwi, strawberries, and sweet potatoes are also rich sources of this essential nutrient.
Health Benefits of Vitamin C
Vitamin C has numerous potential health benefits, making it a crucial nutrient for overall well-being. Below are some of the ways vitamin C may help support your health:
It may help you absorb iron more effectively.
Iron is a critical nutrient for optimal health, and research shows that vitamin C may significantly enhance iron absorption. This dynamic duo supports your body’s ability to absorb iron from plant-based foods, helping keep conditions like iron-deficiency anemia at bay.
It may improve your immune health.
Vitamin C is perhaps best known for its immune-boosting properties. This nutrient helps support the production and function of white blood cells, which are responsible for fighting off infections and diseases. Consuming adequate amounts of vitamin C may help reduce the duration and severity of colds and other respiratory infections.
It may help with collagen production.
Collagen is a protein that plays a vital role in maintaining healthy skin, joints, and bones. Vitamin C helps support collagen production by aiding in the synthesis of this essential protein. Consuming enough vitamin C can help keep your skin looking youthful and supple while also supporting joint health.
How Much Vitamin C Should You Have in a Day?
The recommended daily intake of vitamin C varies depending on sex and age. The Food and Nutrition Board recommends the following daily intake of vitamin C:
- Infants and children (0 to 12 months): 40 to 50 milligrams (mg)

- Adults (19 years and older): 65 to 90 mg for women and 75 to 90 mg for men
