Why Vitamin C is Crucial for Your Body
Vitamin C, also known as ascorbic acid, is a water-soluble vitamin that plays a vital role in many bodily functions. Because it is not stored in the body, a consistent daily intake is essential. Its benefits extend beyond just fighting the common cold and include:
- Immune System Support: Vitamin C stimulates the production of white blood cells, which are crucial for fighting off infections.
- Powerful Antioxidant: As an antioxidant, it helps protect your cells from damage caused by harmful molecules called free radicals, which are linked to chronic diseases.
- Collagen Production: It is essential for the formation of collagen, a protein that supports healthy skin, cartilage, tendons, ligaments, and blood vessels.
- Enhanced Iron Absorption: Vitamin C significantly improves the absorption of non-heme iron, the type of iron found in plant-based foods.
- Wound Healing: It helps the body repair and maintain body tissues, aiding in the healing of wounds.
