Topical magnesium spray works very well but causes a rash
-
I've been taking oral mag glycinate for years. I sort of just assumed it was 'working'. Two days ago I decided to switch to topical magnesium chloride spray, because I decided to take a break from glycine as an experiment. Two things happened: the spray had a huge positive effect on me. I felt it right down to my toes, for hours, and it was so potent, it made me wonder how much of the oral supplement I'm actually absorbing. I have to suspect not much? I never feel anything from the oral supps, despite taking 4 per day.
Two, it very quickly led to a nasty rash on my forearms and torso. I'm disappointed because I thought I'd found a much better way to get magnesium into me. Sadly looks like I'll have to switch back to the oral supps.
Years ago I read a post on the RP forum that shared a study saying topical magnesium absorption was abysmal and a waste of time. So I never tried it. But my own experience these past 2 days would strongly indicate otherwise.

post script: I checked the spray bottle and it says in the first week of usage, you might experience skin irritation. Apply spray to damp skin whilst your body adjusts. So it must be quite common. Think I'll persist and see if it clears up.
