Is the magnesium chloride in Ancient Minerals “Pharmaceutical Grade” or “USP Grade”?

Many manufacturers rely on the phrases “Pharmaceutical Grade” and “USP Grade” to convey a sense of quality to consumers. Both “Pharmaceutical Grade” and “USP Grade” refer to the same thing–the public standards set forth by the United States Pharmacopeia.

There are several aspects of magnesium chloride defined by USP standards, but arguably the most important and controversial is the standard set for maximum allowable heavy metal content. This standard designates how much mercury, cadmium, lead and other toxic metals may be present while still receiving USP certification.

In the case of magnesium chloride, the USP standard allows for a maximum heavy metal content of 10 parts per million (ppm). Because transdermal magnesium chloride comes into direct contact with our skin, we should pay particular attention to the fact that these allowed elements are known toxins. Even as low as a single part per million of mercury can have negative effects.

What this means for you is that manufacturers can casually use the phrase “Pharmaceutical Grade” without telling you exactly what toxic heavy metals exist in the finished product, and at what levels–so long as these levels are below the USP limit.

By no means do we consider this an acceptable practice, and certainly not a suitable method to represent the purity of Ancient Minerals. For that reason, we refer to the “ultra-purity” of Ancient Minerals as being far beyond any pharmaceutical standard that exists in the world, period. We are completely transparent in our efforts to redefine purity.
