I obtained 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.
As the COA shows, Nutricost Potassium Hexahydrate has exceptionally low lead/arsenic/mercury content.
To exceed the 15 mcg per day lead maximum recommended intake, you would have to consume 245 servings. That’s an amazingly clean/untainted product.
Context: Nutricost KCl lead (Pb) content is up to* 58X lower than the NOW Supplements Potassium Chloride.
TIP: most people get too much sodium relative to potassium. To better balance sodium vs potassium intake, I mix Himalayan sea salt about 50/50 with potassium chloride.
* “Up to” because NOW does not offer any more specific res ults other than a range specification of "0 to 586 ppb"; actual content is likely lower and possibly much lower but lacking a measurement one has to assume the highest end of the range.
|mcg per 210mg elemental Mg||Nutricost KCl||NOW Supplements KCl|
|Lead (Pb)||0.0610||0.586 mcg (up to)|
* Given the toxic crap Big Pharma produces, maybe “pharmaceutical grade” means “toxic”?
