Potassium-Magnesium Aspartate, an Overlooked Endurance Enhancer? Acute 100% Increase in Time to Full Exhaustion
1952, Italian Fausto Coppi is drenched with water by a fan during the golden years of the Tour. Question: Can the topical application of K & Mg do the same magic? Answer: That's very unlikely, ... What sounds like a supplement producer was trying to sell his product with a sponsored study is, in fact, the gist of a 1968 study from the Departments of Clinical Physiology and Internal Medicine at the venerable Karolinska Institute in Stockholm, Sweden (Ahlborg. 1968). The authors' conclusion that "[a]fter administration of potassium-magnesium-aspartate [KMgA] the capacity for prolonged exercise increased about 50 per cent" (Ahlborg. 1968) can thus not be discarded as marketing babble. And, before we decide whether it's too good to be true, I'd suggest we take a closer look at the way the data was generated before we either (a) discard it as outdated or (b) get totally excited for nothing.
