Milk of Magnesia Fights Odor

Q. I have suffered from excessive perspiration since I was a child of around eight years old. I have used countless deodorants, antiperspirants, crystals, baking soda, you name it. Nothing worked for very long, not even the prescription formulas.
I’ve been using MoM (milk of magnesia) for roughly four months, and I will never switch to anything else. I use it on my underarms as well as my groin area, and I swear by it. I use a regular generic formula and have never experienced any issues. On days that I shave my armpits, I skip it just in case I might absorb too much magnesium.
A. Milk of magnesia is usually thought of as a laxative to be taken orally, but many people report that it is an effective deodorant when used topically.
Although MoM seems to be gentle, some people develop a skin reaction and should avoid it. We doubt there is much absorption, but loose stools would be a sign of too much magnesium.
