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.

Low Magnesium

The commonest causes of low magnesium are low dietary intake and decreased intestinal absorption. Consumption of large amounts of alcohol and people who have diarrhea may suffer from a low level of magnesium as well. Symptoms of low magnesium include nausea, weakness, sleepiness, personality changes, muscle spasm and loss of appetite.


The bioavailability of Magnesium, either from food or a mineral supplement determines to a large degree, its value to us. A brief examination of the accompanying chart will illustrate the great differences in absorption of Magnesium from various sources. It is important to note that this same absorption disparity is also true for many other minerals including Calcium.


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. The Fumarate is a low molecular weight organic salt which is metabolized with great efficiency is the Kreb’s cycle, perhaps our most fundamental energy-releasing pathway.

Absorption of Magnesium:

*The various mineral form of magnesium are not all equally absorbed. Magnesium glycinate and magnesium oxide and only have about 25% absorption efficiency. The daily recommended allowance is calculated using 25-35% absorption. In contrast, magnesium fumarate, as used in Fura-Mag is much more readily utilized by the body, approaching 85% absorption.
