Magnesium

Therapeutic grade magnesium? Medical grade magnesium? Full spectrum magnesium? This should be about purity, right? We create weaker humans, weaker genetics, heart problems, and calcification issues (arteries, arthritis, etc.) by glossing over the actual source of  magnesium.  Glycinate, Citrate, etc. are just processes but what is the magnesium source? How was the actual molecule obtained?...
