Magnesium orotate is a mineral salt that is normally found in small amounts in all living things. Each molecule of magnesium orotate consists of two molecules of orotic acid in which a single magnesium atom replaces a pair of hydrogen atoms (one from each orotic acid molecule).
Orotate (orotic acid) is a biochemical substance made by all living cells. It is a necessary raw material for making the genetic material: RNA and DNA.
Because magnesium plays such an indispensable role, magnesium deficiencies can have dire effects.
