What are the primary functions of vitamin C in the body?
Vitamin C, also known as ascorbic acid, is a water-soluble vitamin that plays a vital role in various bodily functions, including immune function, collagen production, and iron absorption. It acts as a powerful antioxidant, protecting cells from damage caused by free radicals and promoting the growth and repair of tissues throughout the body. Vitamin C is also essential for the production of white blood cells, which helps to fight off infections and diseases. Furthermore, it aids in the absorption of iron from plant-based foods, making it an essential nutrient for individuals who follow a vegetarian or vegan diet.
Adequate intake of vitamin C is crucial for maintaining healthy skin, bones, and connective tissue. It is involved in the production of collagen, a protein that gives structure to skin, bones, tendons, and ligaments. Vitamin C deficiency can lead to impaired collagen synthesis, resulting in symptoms such as poor wound healing, bruising, and brittle bones. Food sources rich in vitamin C include citrus fruits, strawberries, bell peppers, and leafy green vegetables. The recommended daily intake of vitamin C varies by age and sex, but most adults require around 60-90 milligrams per day to maintain optimal levels and support overall health.
What is the role of B vitamins in energy production and metabolism?
