Vitamin C

Vitamin C, also known as ascorbic acid, is a water-soluble vitamin that is essential for the growth, development, and repair of all body tissues. It plays a crucial role in numerous bodily functions, including the formation of collagen, absorption of iron, and maintenance of the immune system.

Sources of Vitamin C

Some common sources of vitamin C include:

• Citrus fruits (oranges, lemons, limes)
• Strawberries
• Tomatoes
• Broccoli
• Kale
• Bell peppers

Functions of Vitamin C

Vitamin C has several important functions in the body, including:

• Collagen synthesis: Vitamin C is essential for the production of collagen, a protein that helps wounds heal and provides structure to skin, bones, and blood vessels.
• Antioxidant activity: It acts as an antioxidant, helping to protect cells from damage caused by free radicals.
• Iron absorption: Vitamin C enhances the absorption of non-heme iron (iron from plant-based foods) in the gut.
• Immune function: It supports the immune system and helps the body fight off infections.

Deficiency and Excess

A deficiency in vitamin C can lead to scurvy, a condition characterized by fatigue, anemia, and bleeding gums. On the other hand, excessive intake of vitamin C can lead to gastrointestinal disturbances such as diarrhea and cramps.
