Vitamins play a vital role in maintaining health as they support various bodily functions, including metabolism, immunity, and tissue repair. Each vitamin has specific roles; for example, Vitamin C is essential for immune function, while B vitamins are crucial for energy production. A balanced diet rich in fruits, vegetables, whole grains, and lean proteins can help individuals obtain the necessary vitamins for optimal health. Deficiencies in specific vitamins can lead to health issues, emphasizing the importance of adequate vitamin intake for overall well-being.
