It works, but

Posted by 5597920422980173934 on Aug 10, 2016

Well, I think it works. But being an inorganic magnesium, it won't sit in your stomach like you think it will. It's not highly absorbant, so you need more, but more means a looser stomach. So, if you have constipation, here is your cure! If you need a mag that really works, go for an organic form, in a highly absorbable group.

I still prefer tablet form as it's more convenient. this powder takes a while to dissolve.

Gentle on the stomache and good value for money, althpugh it doesn't appear to be as strong as the Magnesium Oxide tablets I take.

Best for colon cleans naturally

Posted by 4712452831627506847 on Jun 06, 2016

I love the laxative properties of this product! It help with constipation but moreover I did a week long colon cleanse and feel so much better! It's natural and cause no side effects. no habit forming. If you think of a detox think magnesium oxide! the best magnesium supplement for me so far.
