The "oil" is just a supersaturated Magnesium Chloride solution. It is not so expensive if you find it in a health food store. You can also make your own by getting the flakes. This is especially good if you have a leaky gut, since it goes through the skin. Epsom Salts are also wonderful and cheap for baths. You could also encapsulate Epsom salts and take it internally as a cheap Mg supplement. If you take too much you will get the runs and I would be sure to take it with food. Full body soaks are better than foot baths, but make sure to make the water strong enough and only stay in about 20 min. Dr. Singha's mustard bath is good for soaks too, and you can double it up with Epsom Salts.

yes i think using epsom salts in place of the magnesium chloride will be just as effective. when both MgSO4 and MgCl2 are mixed with water they break down and the magnesium is the same in both forms. sharon

I use the brand that she recommends for transdermal application. Ancient Minerals, I believe. I order it from Amazon.com. I also use Concentrace Minerals. You can put that in your liquids and food. It tastes awful, so use it sparingly. I do foot soaks with Epsom Salts almost everyday now. It's a cheap, easy way to go. You can find Epsom Salts anywhere, but I recommend that you supplement with the oil too.

Good luck!
