Not all magnesium is created equal. Glycinate for sleep and calm, Citrate for digestion. Pick the right form for your needs.

The Verdict

This isn't really a 'better' comparison, but a 'use case' one. Choose Glycinate if you want better sleep and relaxation without tummy trouble. Choose Citrate if you need help with regularity.

Deep Dive Analysis

Magnesium atoms are unstable alone, so they are bound to other molecules. 'Citrate' is bound to citric acid—it draws water into the colon, making it an effective laxative (but poor for absorption). 'Glycinate' is bound to glycine, a calming amino acid. It absorbs easily into the bloodstream to relax muscles and the brain. If you buy Citrate for sleep, you'll likely just end up in the bathroom all night.

Frequently Asked Questions

Can I take both?
You can, but watch your total dosage. Too much magnesium of any kind will cause loose stools.
Which is better for anxiety?
Glycinate is far superior for anxiety due to the glycine component.
