Bests & Worsts Reviews from Amazon

I was skeptical of the claims that the product contained lead, due to the lack of provided information. As a result, I tested my current batch of Lysine (also purchased from Bulk Supplements) just to be sure. Employing the use of a water testing kit I use yearly to verify water quality reports, I tested filtered water, as well as filtered water containing the suggested dosage of lysine. The results of the test were negative--the Lysine tested practically identical to the filtered water--at this point, I ordered the Magnesium Glycinate from Bulk Supplements with confidence that the company was not contaminating products. The Magnesium Glycinate arrived today. Packaging was not tampered with. We planned to take it at night before going to bed, so the Magnesium would help us relax and sleep better. Before adding some to a cup of Activia, I performed the water test. Using the same method--identical glasses, filtered water--I added a serving of Magnesium Glycinate (1/2 teaspoon). The MG strip immediately changed color. It changed so quickly, that I could see it in the milky water. Results (and TL;DR): POSITIVE for high alkalinity (240 - 400ppm range, causing erratic pH levels and calcification) POSTIVE for extremely high pH (above 9.0, but this is about where you could expect Magnesium to naturally map on the pH scale) POSITIVE for extreme hardness (looks slightly above 1000 PPM, due to the very pink color) NEGATIVE for Iron POSITIVE for Copper in moderately high levels POSITIVE for Lead in extreme levels (higher than 50 ppb, the color turned fuscia) POSITIVE for Nitrate -- this color doesn't look like anything in the range of the scale, however POSITIVE for Nitrite -- as with Nitrate, the color doesn't look anything like the scale NEGATIVE for Residual Chlorine POSITIVE for Fluoride, though still within OK levels I do NOT advise using this product until product safety can be verified.
