Do you test for heavy metal contamination? If so, can you post the results and how you test?

Thank you for your question. Our Magnesium Chloride is pre tested and highly purified to remove all harmful contaminants and is also used as one of the electrolytes in dialysis solutions for kidney patients for which the specifications for production are controlled and secure.Our testing facility is staffed by PhD chemists and houses specialized instruments that measure metals in the parts per billion level. It is a pharmaceutical laboratory (not some environmental laboratory having no expertise in US Pharmacopeia methodologies) and specializes in testing of saline matrixes, which is an extensive several weeks process.You can be assured that the mercury level in the Magnesium Chloride base for Magnesium Oil and Magnesium Oil with Aloe Vera is below a single part per million ~ a level often so low as to be beyond detection.Please find below the full analysis results.

The testing facility (unlike many others) is not only staffed by PhD chemists (not lab techs) but also houses specialized instruments that measure metals in the parts per billion level. It is a pharmaceutical laboratory (that is NOT some environmental laboratory that uses ASTM methods to test waters and wastes ....having no experience nor expertise in US Pharmacopeia methodologies nor the cGMP requirements that go beyond merely testing to USP monographs but qualifying raw materials, etc.) but specializes in testing of saline matrixes - few bother to validate their results in specific matrixes. Validation is an extensive process involving proving the accuracy, precision, robustness, specificity, detection limit, quantitation limit and linearity range for identifying the analytes in question in the saline matrix. In layman's terms, pick say....aluminum. Aluminum can be measured in water. Measuring aluminum AND BEING CERTAIN you are measuring Aluminum actually in a salt matrix....say 30% Magnesium chloride - that's a whole different matter.

What is the return policy on this item?

IMPORTANT Amazon will say no but that's not true. We stand by our satisfaction guarantee, but because the product is technically an "oil" they don't allow for returns via the mail. So if the product doesn't work for you, just send us (the seller) a message and we'll take care of you right away.

When and how would I start noticing any difference at all? I see Nothing so far

I believe we are all different, but for me, the burning/itchiness is a clear sign that one has a deficiency. I started to notice a big difference after the first use in my hair, sore areas, and skin.

How do I receive the e-book?

You get the free E-book (Electronic book) with the first & second emails we send you after your purchase as an attachment in PDF format.
