Vitamins (e.g., Vitamin C, Vitamin D)

Vitamins are essential nutrients the body needs to function properly, support immune health, and maintain energy levels. They are naturally found in foods like fruits, vegetables, dairy, and grains. For example, Vitamin C helps protect cells and supports healing, while Vitamin D aids in calcium absorption for healthy bones. Since the body can't produce most vitamins on its own, they must be obtained through diet or supplements. A balanced intake ensures overall health, but excessive consumption can be harmful. Thus, maintaining a varied diet is key to getting the right amount of each vitamin.
