Magnesium plays a number of roles in the body, being required for more than 325 enzymatic reactions, including those involved in the synthesis of fat, protein and nucleic acids, neurological activity, muscular contraction and relaxation, cardiac activity and bone metabolism.
Even more important is magnesium's role in both anaerobic and aerobic energy production, particularly in the metabolism of adenosine triphosphate (ATP).
Heavy sweat loss can lead to a decrease in magnesium concentrations and may interfere with the important functions for which magnesium and other electrolytes are responsible.
Low blood magnesium levels during exercise have been cited as a cause of muscle fatigue, irregular heartbeat and contribute to muscle cramping and dehydration.
Adequate magnesium must be available to relax muscles and relieve cramping, stiffness and soreness. It functions as an inhibitor to relax the nerves by helping them to not become overly excited.
The form of Magnesium can directly affect its absorption and function. Magnesium oxide is very hard to absorb and tends to stay around in the GI Tract causing diarrhea with over consumption leaving small deposit like rocks. Magnesium aspartate or citrate has a higher percentage of absorption.
The GI absorbability of magnesium oxide and magnesium citrate were compared (Lindberg et al., 1990).
Magnesium citrate was significantly more soluble than magnesium oxide.
Absorption of the two magnesium formulations was also compared by measuring the urinary levels of magnesium, and the citrate form was absorbed to a much greater extent than the oxide.Magnesium salicylate is a common non-steroidal anti-inflammatory used to treat mild to moderate muscular pain, headaches, general back pain, and certain joint pains.
The three forms of magnesium are used in Rapidade™ and Rapid Recharge™ to help prevent cramping, muscular pain and increase hydration and energy levels.
