Certificate of Analysis (COA): Nutricost Magnesium Chloride Hexahydrate
re: certificate of analysis
See Certificate of Analysis for Food Supplements: How to Interpret.
Today I obtained the COA for Nutricost Magnesium Chloride Hexahydrate, the phone being answered instantly by a very nice young person. Excellent customer service.
See also the COA for Nutricost Potassium Chloride.
Nutricost manufactures their products in the USA and they test every batch them make, so they say when I called them. I have no affiliation, but I admire a company that tests every batch and makes it right here at home. Hence I wish to call them out as a company doing things right and deserving of your business.
My search is over for the best source of MgCl. As seen below, Nutricost Magnesium Chloride Hexahydrate has exceptionally low lead/arsenic/mercury content according to its COA.
Nutricost Magnesium Chloride Hexahydrate @AMAZON
Nutricost Magnesium Glycinate @AMAZON (half as costly per serving, COA as yet unexamined)
To exceed the 15 mcg per day lead maximum recommended intake, you would have to consume 1376 servings [15 mcg / 0.0109 mcg per serving]. That’s an amazingly clean/untainted product. Note also the similarly nil levels of arsenic and cadmium and mercury.
I compared the figures below to the “pharmaceutical grade”* MgCl product I was using.
Nutricost lead level amount of MgCl hexahydrate is about 98X lower than the product I had been using, the Heliotropfen.
|mcg per 210mg elemental Mg||Nutricost MgCl Hexahydrate||DoubleWood Magnesium L-Threonate||RnAReSet ReMag||Heiltropfen Magnesium Chloride Hexahydrate|
"Heavy metals (as Pb)" 5.33
* Given the toxic crap Big Pharma produces, maybe “pharmaceutical grade” means “toxic”?
