Magnesium is an essential mineral nutrient for life and is present in every cell type in every organism.

Magnesium is necessary for the formation of bone and teeth and for normal nerve and muscle function. It is also essential for cell energy production. Many enzymes in the body depend on magnesium to function normally.

The value of Magnesium supplements is dependent upon both their absorption efficiency and bioavailability. The U.S. RDI for Magnesium was established with the understanding that this mineral was absorbed with an estimated efficiency of about 30%. For instance, the RDI for Magnesium is 400 mg. This means, under desired optimal conditions with 400 mg of Magnesium in the diet, we should absorb 120 mg. It is this amount, the 120 mg of absorbed Magnesium, that has been deemed to be the amount that is necessary to fulfill our basic metabolic needs.

Each capsule of Fura-Mag supplies 140 mg of elemental Magnesium as Magnesium Fumarate. With an absorption efficiency of 80%, just one capsule of Fura-Mag will provide about 110 mg of bioavailable Magnesium. Therefore, two capsules will provide us with 220 mg of Magnesium or 180% of RDI equivalence, based on absorption.
