Eight in-depth reviews covering elemental dose, testing evidence, cost per 100 mg and customer reviews, in our provisional editorial order.
The most documentation you can check yourself of any product we compared, at one of the lowest costs per 100 mg of elemental magnesium.
A simple 200 mg capsule with NSF Certified for Sport status you can look up yourself. The certification is the reason to buy it; better sleep is not proven.
A clearly labeled 275 mg serving with a simple formula. Our editors verified a lot report privately; the gap is that you can't check it yourself yet.
An NSF Certified for Sport powder with a short ingredient list. It costs the most per 100 mg of anything we compared.
The largest serving in our comparison, with test reports linked from the product page. It was sold out when we checked.
A small 120 mg capsule that makes it easy to fine-tune your dose. The brand page doesn't name third-party testing for this product.
The lowest cost per 100 mg we found, from a widely sold brand. Testing is described in general terms, and the label allows more than the upper limit.
An inexpensive Albion chelate that shows up next to magnesium glycinate everywhere. It is a lysinate glycinate blend, not glycinate alone.
