My first post. I've been using magnesium oxide to prevent constipation. My understanding is that magnesium oxide has a poor absorption rate - and therefore excels as a laxative.

I'm attempting to 'fine tune' my magnesium regimen. My question: Is magnesium oxide a better laxative choice than magnesium chelate - which appears to have a higher absorption rate?

I guess I'm looking for the least absorbable magnesium which should equate as being the best magnesium laxative.
