I, too, have been reading a bit about magnesium supplementation and transdermal therapy. Long ago in my journey, a Feldenkrais practitioner insisted I supplement with Magnesium during my therapy with her. I was pointed to a health food store where the pills I bought were GIANT, and I only took them now and then when I had the courage.

Later, I tried the Citrate variety in powder form, but that proved to be more of a laxative and I could never get into higher mg supplementation with it.

I'm now using a brand called Jigsaw http://www.jigsawhealth.com/supplements/magnesium The pills are easy to swallow and I have been able to slowly get up to 750mg over the past weeks with minimal gastric issues.

I'm also using Ancient Minerals Magnesium Oil and Lotion. I made the mistake of not rinsing off the oil after 20 min and got into trouble with rashes and skin irritation. The lotion causes no problems, but it absorbs at a lower rate.

It's to early to tell if anything positive will come from this trial. I always assumed I ate a well-balanced, close to the source diet as possible, but when you read about the foods which are high in magnesium, I ate very few. Going through this TOS process has been devastating on my adrenals, and in addition, I ate a calcium rich diet to fend off early-onset of Osteoporosis.

Sounds like it takes a couple of months at minimum to "notice" any benefits from supplementation for my use, so I'll keep you posted.
