Does Life Extension Neuro-Mag supplement [magnesium threonate (Magtein)] have heavy metal contaminant issues?

[Rhyothemis]

If anyone has access to Consumer Labs or similar testing data on contaminants in magnesium supplements, can you please check to see if LEF brand's NeuroMag supplement (which is Magtein magnesium threonate) ranks? Also would be interested in ranking/levels of any supplement that contains only Magtein.

The concern stems from magnesium supplements frequently being contaminated with heavy metals such as lead, cadmium and arsenic.

Have you contacted the company?I'll be interested in hearing more about this.

Life Extension has a protocol for Parkinson's.

Customer support should be helpful. A couple of years ago I spoke with Wanda and she was very helpful.

Consumer Labs tested a large number of different magnesium supplements, but not Life Extension brand. All of the ones that they did test got a "pass" on heavy metal contamination. None of the supplements tested contained magnesium threonate.

I just emailed them to ask about the Certificate of Analysis for Neuro-Mag

I received a lengthy email but I am going to try to cut and paste the most pertinent part of it:

Please rest assured that all Life Extension's products, including Neuro-Mag® Magnesium L-Threonate, undergo rigorous testing at multiple stages of the manufacturing process to determine compliance with strict acceptance criteria outlined in our stringent product specifications. Only products that meet this strict set of standards may be released by our Quality Control personnel to be purchased by customers. We ensure our guarantee through stringent monitoring and not relying on verbal promises. All of our raw material vendors undergo an extensive qualification process conducted by our Product Development, QA/QC, and Purchasing departments. The testing procedures include (but are not limited to) chemical identification [using Fourier transform infrared spectrophotometry (FTIR), ultra-violet (UV) or high-performance thin-layer chromatography (HPTLC)], physical characteristics, potency/strength confirmation, microbial analysis, and other contaminants including heavy metals to verify and approve the Certificate of Analysis (COA) for each material. Complete raw material COAs that meet our specifications are mandatory for every lot of raw material that is received for use in our products. Raw materials are only released for use in our products when they have met Life Extension's specifications. Our raw material qualification process assures that ingredients that are grown around the world meet United States Pharmacopeia (USP) standards for heavy metals, pesticides, and residual solvents used during manufacturing.

I use Mercola. Costs more but his stuff is more strictly controlled.

CL hasn’t rated Magnesium Theronate, unfortunately
