1. Understanding Vitamin C and Its Importance

Vitamin C, also known as ascorbic acid, is a water-soluble vitamin vital for numerous bodily functions. It acts as an antioxidant, protecting cells from damage caused by free radicals, and plays a key role in collagen synthesis, immune system support, and iron absorption.

1.1. The Role of Vitamin C in the Body

Vitamin C is essential for several physiological processes:

Collagen Synthesis: Vitamin C is required for the production of collagen, a protein that provides structure to skin, tendons, ligaments, and blood vessels.
Immune System Support: It enhances the function of immune cells, helping the body fight off infections and diseases.
Antioxidant Protection: As an antioxidant, vitamin C neutralizes harmful free radicals, reducing oxidative stress and the risk of chronic diseases.
Iron Absorption: It improves the absorption of non-heme iron, the type of iron found in plant-based foods.

1.2. Recommended Daily Intake of Vitamin C

The recommended daily intake (RDI) of vitamin C varies based on age, sex, and life stage:

Adult Men: 90 mg per day
Adult Women: 75 mg per day
Pregnant Women: 85 mg per day
Breastfeeding Women: 120 mg per day

Smokers are advised to consume an additional 35 mg of vitamin C daily, as smoking depletes vitamin C levels in the body.

1.3. Benefits of Getting Enough Vitamin C

Ensuring adequate vitamin C intake leads to various health benefits:

Reduced Risk of Chronic Diseases: Its antioxidant properties help lower the risk of heart disease and certain cancers.
Improved Immune Function: Adequate vitamin C supports the immune system, reducing the severity and duration of colds.
Enhanced Skin Health: Collagen synthesis promotes healthy, youthful skin.
Better Iron Absorption: Vitamin C helps prevent iron deficiency anemia, especially in vegetarians and vegans.
