@honour.health: In a pure magnesium glycinate supplement, the elemental magnesium amount should equal no more than 12 to 14% of the total magnesium amount. Elemental magnesium is the amount of actual magnesium in a magnesium supplement. With the remaining weight being the amino acid glycine, which the magnesium is bound to to create magnesium glycinate. There are times however, often to keep the cost down, where brands will mix in a cheaper, lower quality form of magnesium like magnesium oxide, into their magnesium glycinate supplement. This process is called buffering, and will reduce the overall quality and effectiveness when compared to a pure magnesium glycinate supplement. #magnesiumglycinate #magnesiumglycinatesupplement #magnesiumglycinatebenefits #magnesiumsupplement
