@matthewnoconnor: Supplement companies can often mix in lower quality forms of magnesium, like magnesium oxide, into their magnesium glycinate supplements. This process is called buffering which reduces the quality and overall effectiveness of a pure magnesium glycinate supplement. There is a way you can check though whether you’re buying a pure magnesium glycinate supplement and that’s by dividing the elemental magnesium amount by the total magnesium amount to give a %. A pure magnesium glycinate supplement should contain no more than 12 - 14% elemental magnesium. If your magnesium glycinate supplement contains more than 12 - 14% elemental magnesium, there’s a high likelihood that its been mixed with a lower quality form. #magnesiumglycinate #magnesiumglycinatesupplement #magnesiumglycinatebenefits #magnesiumsupplement
