what the evidence says
Magnesium helps most clearly where levels are low: evidence supports better sleep and calmer stress response in deficient and older adults, with modest effects otherwise. Glycinate is well absorbed and gut-gentle, and the attached glycine may itself mildly support sleep, though that is lightly evidenced at these doses.

Reviewers treat it as the smart default: iTested certificate published, price under the big names, and the same calm-sleep effect as pricier glycinates. Capsules swallow easily. Complaints are rare and mostly about stock running out.
