For an ingredient to receive a USP (United States Pharmacopea) listing, first, the UPS must make a monograph for the ingredient, which is a minimum set of standards to which the ingredient must pass. In other words the ingredient must be free from toxins.
Since Magnesium Di-Potassium does not yet have a monograph of its own, we have looked at the monograph for similar ingredients, namely calcium-di sodium EDTA and di-sodium EDTA.
Medicardium has met and exceeded the purity of these similar ingredients in terms of heavy metal content. Analytic tests done at Galbraith Laboratories, an independent analytical lab has shown levels of Lead, Mercury, Cadmium, Arsenic and Barium all undetectable (below 2.5 parts per million) and NTA (nitrilotriacetic acid) to be below .01%.
The USP monograph allows for heavy metal such as lead to exist in EDTA products up to 20 parts per million. Medicardium is below 12.5 parts per million and probably even lower.
The USP monograph for NTA is .1%. Medicardium has tested below .01% (a minimum of 10 times purer than USP standards. This is important since NTA is a suspected carcinogen.
Some critics claim that Magnesium Di-Potassium has been used as a plant fertilizer. This is true, since crops as well as humans are often deficient in the elements magnesium and potassium. Rest assured, we do not used fertilizer grade EDTA in Medicardium.
We at Medicardium meet and exceed the USP standards set for EDTA. To our way of thinking, USP grade is not stringent enough. Laboratory reports available upon request.
