In an effort to provide the best quality products, we have made a Magnesium Citrate formula change. Whereas it previously contained 140 mg of elemental magnesium per capsule, it now contains 135 mg per capsule. The citrate that the magnesium is bound to for enhanced absorption over other forms of magnesium take up a lot of room in the capsule. Since we do not use magnesium stearate, it was difficult to squeeze 140 mg of this well-absorbed form of magnesium into our largest capsules. The attempts to do so often resulted in the capsules not locking properly and loose powder appearing in the bottle. This slight decrease should alleviate this problem.
a well-absorbed form of magnesium*
A study comparing the bioavailability of magnesium citrate with magnesium oxide (a form found in many poorly-absorbed dietary supplements) found significantly greater absorption of magnesium citrate than magnesium oxide in healthy volunteers.* The same researchers examined solubility and found magnesium citrate to be 55-percent soluble in water; whereas, magnesium oxide is virtually insoluble. The more water-soluble a mineral chelate is, the more absorbable it is in the body.*
Magnesium and citric acid have both been found to decrease the precipitation of calcium oxalate and calcium phosphate in the urine, thus supporting good kidney health.* The combination of magnesium with citrate in Thorne's Magnesium Citrate offers an attractive combination for individuals with a propensity to have calcium oxalate and phosphate particles in their urine – thought to be about 10 percent of the U.S. male population.*
Magnesium is present in all cells of the body and is involved in over 300 enzymatic processes, including energy production.* Magnesium is essential for maintaining normal bone density, normal cardiac rhythmicity, normal pulmonary function, and normal blood glucose regulation.* Other body functions requiring magnesium include nerve conduction, methyl-group transfer, conversion of pyridoxine to pyridoxal 5'-phosphate (the active form of vitamin B6), production of energy, and muscle contraction.* Magnesium supplementation appears to be a significant support to maintaining already normal bone density.*
