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.
