> I assume this is why magnesium salts act as laxatives

This is a side issue, but apparently it's a different reason.

From https://ods.od.nih.gov/factsheets/Magnesium-HealthProfession... : "The diarrhea and laxative effects of magnesium salts are due to the osmotic activity of unabsorbed salts in the intestine and colon and the stimulation of gastric motility."

Sounds like it's only part of the reason, if I'm correctly parsing "... and the stimulation of gastric motility" as a second mechanism of action.

Oh, good point. I was reading it as if it said "the resulting stimulation", but what you're saying makes more sense.
