An essential mineral in human nutrition that is involved in more than 300 metabolic reactions. Magnesium is necessary for every major biological process, including the production of cellular energy and the synthesis of nucleic acids and proteins.

Vitamin A plays an important role in vision, bone growth, reproduction, cell division and cell differentiation, which is the process by which a cell decides what it is going to become. It also helps to maintain the surface linings of the eyes and the respiratory, urinary, and intestinal tracts. When those linings break down, bacteria can enter the body and cause infection. Vitamin A also helps maintain the integrity of skin and mucous membranes that function as a barrier to bacteria and viruses.

Vitamin C promotes healthy teeth and gums, helps in the absorption of iron and helps to maintain normal connective tissue. It also promotes wound healing.

Vitamin B6 is a water-soluble vitamin that is needed for more than 100 enzymes involved in protein metabolism. The nervous and immune systems also need Vitamin B6 to function efficiently, and the vitamin is essential for red blood cell metabolism. In addition to helping make hemoglobin (which carries oxygen to the tissues), Vitamin B6 helps to increase the amount of oxygen carried by the hemoglobin.

Vitamin B12 helps maintain healthy nerve cells and red blood cells. It is also needed to make DNA, the genetic material in all cells.
