Thorne's Magnesium Bisgylcinate is NSF Certified for Sport®. Magnesium is essential for the health of the heart and blood vessels, brain, bones, skeletal muscles, lungs, and pancreas.* As a cofactor for more than 600 enzymes, magnesium supports numerous mechanisms of action; for example, it relieves bronchial spasms, relaxes smooth and skeletal muscle, enhances insulin sensitivity, and is a cofactor in numerous enzymatic reactions necessary for energy production.* Other magnesium mechanisms of action include modulating intracellular electrical activity and improving endothelial-dependent vasodilation, which support heart and lung health.* Thorne's Magnesium Bisglycinate is formulated for optimal absorbability.* Its molecular structure also reduces the laxative effect typically seen in magnesium supplements.* Lightly sweetened with Monk Fruit and a hint of citrus. A low level of magnesium is associated with an increased level of C-reactive protein.*
Magnesium bisglycinate demonstrates better absorption than other magnesium supplements.* A crossover study found that serum levels of magnesium over eight hours were highest for magnesium bisglycinate, followed by dimagnesium malate and magnesium oxide.*
The glycine in this ingredient enhances its solubility and absorption by decreasing the pH of the intestines.* The glycine that takes up space on the magnesium molecule also decreases the propensity of the magnesium to complex with plant-based phytates that would otherwise interfere with its absorption.*
Because an athlete needs to know that his or her supplements are trustworthy and compliant, every batch of an NSF Certified for Sport® product is tested for compliance with label claims and to ensure the absence of more than 200 substances banned by many major athletic organizations, including stimulants, narcotics, steroids, diuretics, beta-2 agonists, and masking agents.
