This is probably already known here but just in case.

I bought Pure Magnesium Chloride Brine Flakes.

1/2 cup water in a saucepan and bring to a boil
add 1/2 cup magnesium flakes

It will dissolve in less than a minute or so. Then remove from the heat, cool and put it into a little spray bottle. Much less expensive than buying the oil and why when it's this simple to make your own?

The skin creates quite a barrier to things moving into the body.

I don't believe the "oil" form is very useful therefore. It has no carrier, to carry the magnesium thru the skin.

The Morton's lotion however, does go into the skin and the mag goes with it. My blood pressure readings prove that, by decreasing when I use it.

The special compounded creams for pain relief given by doctors and made at compounding pharmacies, use a special transdermal gel that carries the drugs thru the skin barrier.
I bought some of this at a compounding pharmacy for our late cat Oreo who was impossible to pill... for her prednisolone chemo treatments. I mixed her dose into a smidge of the transdermal vehicle, and rubbed it into her ear and it worked like a charm. I had to wear gloves though so it wouldn't get into me.

The Morton's is only $5.95 for 8 oz.... not expensive at all for what you get in return.

You can do what you like, though, but it seems like alot of effort when a product is available that is much better than a concentrated magnesium aqueous solution.

That's good to know. What if I put on a light coating of 70% DMSO first? I also have the Mortons.

When you circumvent the skin barrier with something like DMSO....you run the risk of getting TOO MUCH of the magnesium into your body. I wouldn't begin to know how you could make this without proper measurement of the magnesium flakes and water, to get a safe concentration to mix with the DMSO.

The skin is a very effective barrier to avoid toxins and poisoning.
Epsom salts baths need time to work, and even then the amount of mag that gets in is still quite small.

Any contaminant in the magnesium you use to make the solution will also go into the body with the DMSO. And there will certainly be other substances in that product you are using. Food grade is not 100% pure....it is just cleaner than non food grade.

Just a quick look around Google, and the flakes are not cheap either. My magnesium lotion lasts me MONTHS...about 3 months a bottle. This is because you only apply a small amount...the lotion carries it right thru the skin barrier.

Sometimes do it yourself products may backfire on you!

Well I've used DMSO for about 20 years now for various things and it didn't kill me yet. But I'll take your advice and not do that. But if it sits on your legs all day won't it get in to some extent like the Epsom salts? And it's not expensive where I got it on Amazon. I can make enough for a year I'll bet on this jar which was less than $15.

Of course if it doesn't work that's a moot point. However then hundreds of reviews on amazon are dead wrong.

Do what you want.... I am only pointing out what may happen to you.

I personally would not use DMSO, myself.

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.
