Vitamins are essential for maintaining overall health as they regulate numerous biological processes in the body. They support immune function, helping the body fight infections and diseases. For example, vitamin C strengthens immunity, while vitamin D enhances the body's defense system. Vitamins also play a role in metabolism, helping convert food into energy. B vitamins, such as B6 and B12, are essential for energy production and brain function. Additionally, vitamins contribute to cell growth and repair—vitamin A supports skin and eye health, while vitamin E acts as an antioxidant to protect cells from damage. Some vitamins, like vitamin K, are important for blood clotting, preventing excessive bleeding from injuries. Since different vitamins serve different functions, maintaining a balanced diet with a variety of nutrient-rich foods is necessary to prevent deficiencies and promote long-term health.
