Check with the dosing on the product label, since generally lower doses are used for acid reduction (1-3 TEAspoons), and higher to move the bowels (1-3 TABLEspoons).

Not for long term: Side effects include hypermagnesemia which could cause heart rhythm trouble. Hypermagnesemia occurs specially in persons with slow kidneys. Would suggest alternating it with other cathartics if you have constipation. Several options exist i.e. Senna preparations, plymerizedethylene glycol preparations called MiraLAX (polyethylene glycol) or its generic form, flaxseed oil, and prune juice. May check with pharmacist too.

Also, if you have long term constipation, you need to make sure a physician has cleared long term treatment i.e. cancer colon was excluded by a scope.
