What will milk of magnesia (magnesium hydroxide) do for constipation?

Laxative: Cheap forms of mg like the oxide in milk of magnesia (magnesium hydroxide) are good laxatives. We are all low on mg andleads to all sort of health concerns including hypertension, muscle aches, leg cramps, poor sleep, so i like adding mg glycinate 1 cap 2 x daily to support heaalth - it as a chelated form has less bowel effect and is a better replacement supplement.
