"Cures consitpation" because Mg Oxide is a laxative! Poor quality Magnesium.
Posted by 4616715287013331533 on Apr 30, 2014
I have supplemented with Magnesium for 20 years, using many products. Beware this one. The ingredients say "Magnesium (from Magnesium Oxide, Magnesium Citrate and Magnesium Aspartate)". Because this product did nothing to prevent leg cramps, whereas other Magnesium 'chelate' and 'citrate' supplements do, I became suspicious that the ingredients label may be little more than a dishonest up-sell for mostly cheap and useless Magnesium oxide. Then I spotted a reviewer saying "Cures constipation!", which confirmed my suspicion. Magnesium oxide is a well-known laxative. That's why it's such a poor Magnesium supplement - it goes straight through you and does not absorb. If you want a semi-natural laxative, go for it. But if you want an actual Magnesium supplement to benefit heart health, anxiety or muscle cramps, make sure you choose a product genuinely containing a Magnesium chelate (eg aspartate or orotate) or at least citrate.
Gives me cramps

Unfortunately something in this formula gives me hours of stomach pain. Just plain discomfort without diarrhea or upset. I will try taking this few more times with different foods but if the pain follows will have to bin this and try different brand mag. I read that aspartate and glutamate forms of magnesium should be avoided.
Too big to swallow

I am scared to swallow them whole so will have to open the capsule and dump the contents out to get it down.
Not the best forms of magnesium

Magnesium oxide is not a very absorbable form - better to choose Mag glycinate or citrate. It's not how much you take that matters but how much you absorb.
