I totally agree with this and have seen this time and time again. The 100% pure on the label is likely not accurate. When an analysis is performed on a non-drug product like this, it is very minimal and generally performed with instruments that aren't sensitive enough to truly see the related substances, excipients or impurities.

These flakes are likely manufactured by some type of heating/evaporating/cooling process. This is one of the places where impurities find their way into the product.

If I were considering this product, I would probably call the company and ask them to provide me a Certificate of Analysis. If they are a good company and doing things above board, they should be able to provide this C of A easily and match it to the batch on your product. I'd want to know both the purity and potency before I made a solution of this.

Just my 2 cents....

I looked up these flakes, and sure enough...they come from evaporated Dead Sea electrolytes. That means many potential things you don't want going thru your skin, may be in them.
Some of the makers clearly state, they do not have certification for oral use.

I dig the Morton's cream. Sure, there are times where it isn't enough, but I am betting nothing would do the job at those times. Well, maybe something, but nothing in my current arsenal.

I know a lot of folks who make their own mag oil. I've used it a lot over the years, never made my own...tends to irritate some areas of my skin. I use DMSO for many years and dilute the 99% solution about 70/30 with distilled water. Helps ease my joint pain. I'm a member of a yahoo DMSO group and everyone is fine on DMSO. I'm trying a bottle of Mortons on my next Amazon order. Later all.

Since I'm taping my knee and ankle, I don't use the topicals I used so much now. Gotta buy more tape thou.

How does taping help?

Primarily, stability of joints. I sleep with taping and can walk much better in the morning after a night's sleep. You can find a lot of info on taping on the net. Many PT's and chiro's use it. And many learn how to use it on their own, videos, instructions, youtubes online.

Thank you. By better do you mean more stable or less pain. Does it help with foot pain at all?
