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.

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.

Arrived damaged and leaking

Absolutely disappointed that the magnesium oil spray arrived damaged and was leaking all over the front door. The spray bottle is damaged beyond repair and the contents are half full.

Mes conclusions au bout de 19 jours d'utilisation : 1- Un grand allié du sommeil => cela faisait plus de dix ans que je n'avais pas dormi comme je dors à présent (sans interruption et plus de douze heures d'affilées, le we). 2- Plus efficace que tout gel froid ou autre permettant de calmer le syndrome des jambes sans repos => j'ai ce syndrome depuis l'enfance, alors je suis plus qu'affirmative sur l'efficacité. 3- J'ai retrouvé une forme globale correcte, mais surtout une sérénité perdue depuis longtemps. Bref, je suis extrêmement satisfaite. Attention toutefois : au début, je dirais les 4-5 premiers jours, vous n'allez pas apprécier la rugosité engendrée (comme lorsque l'on revient de la mer sans s'être douché à l'eau douce rapidement). Mais en toute sincérité, on s'y habitue (au pire, si ma mémoire est bonne, il y a une version de ce produit avec de l'aloé vera. Vous allez recevoir la notice par mail, dès réception du spray et tout est très très bien expliqué.
