Vitamins and minerals are essential for the proper functioning of the human body, as they participate in many vital functions. Vitamins help to strengthen the immune system, produceenergy(such as B vitamins), and to maintain bone health (with thevitamin Dfor calcium absorption). Minerals, on the other hand, are essential for processes such as muscle contraction (calcium, potassium), nerve transmission (sodium, calcium), and the formation of red blood cells (iron). In summary, they work synergistically to support growth, cellular repair, and the regulation of various bodily functions.
