Since it does have some absorbability through the skin, it is also found in Epsom bath salts.Magnesium citrate: A commonly used form that has a good bioavailability compared to oxide.

Due to the calming and relaxing effect of both glycine and magnesium, this combination has been used successfully for chronic pain and muscle hyper tonicity.3 Magnesium Malate: This less well-known combination has been studied for use in fibromyalgia.

Since malate is a substrate in the cellular energy cycle, it can help improve ATP production; there is some preliminary evidence that it may reduce muscle pain and tender points in fibromyalgia patients.4 Magnesium Orotate: This is another relatively unknown chelate combination containing orotic acid.

Another factor that contributes to magnesium deficiency is that it often is depleted by various common conditions (i.e. As a supplement, magnesium is most commonly found in small amounts in multivitamins and in certain over the counter laxatives.

Minerals such as magnesium or calcium are combined with another molecule to stabilize the compound.

This form has good bioavailability has had been studied specifically for heart health.

Orotates can penetrate cell membranes, enabling the effective delivery of the magnesium ion to the innermost layers of the cellular mitochondria and nucleus.

Magnesium Glycinate: Glycine is a well-known calming amino acid.

This combination has good bioavailability and does not have a laxative effect since glycine is actively transported through the intestinal wall.

There were some promising clinical trials conducted in the 1960s that found a combination of magnesium and potassium aspartates had a positive effect on fatigue and they reduced muscle hyper-excitability.2 Physiologically this makes sense since both magnesium and aspartic acid are critical players in cellular energy production.
