I have read on this blog that many people have benefited from magnesium supplements for constipation.

I have a "severely" redundant colon but no twisting and no pain. I have IBS-C that is caused by most types of food as well as general anxiety.

I have found that a magnesium supplement helps with both the constipation and the general anxiety -- magnesium is "proven" to actually be good for both.

As my system is sensitive. I use a gentle, low dose brand recommended by one of my doctors. Hilma Gentle Bowel Movement Support.

I take one capsule at the end of each of my three main meals, based on a study of its effect on constipation. Following the bottle's direction to take two at night didn't seem useful.

One needs to drink enough drink water when taking magnesium supplements.
