Magnesium for Sleep: The Complete Guide
How magnesium supports sleep, which forms suit the evening, and how to take it — plus why Oh!Mg pairs three forms with calming botanicals.
Reviewed by Dr Elena Seranova
Magnesium is one of the most popular supplements for winding down at night — and for good reason. It plays a role in the nervous-system pathways that help the body shift from “on” to “off”, and many people are quietly low on it. The catch is that the form, the dose and the timing all matter, so “magnesium for sleep” is really a question of which magnesium, taken how.
This pillar is the hub for the rest of our magnesium-and-sleep guides. Below, the short version; the detailed spokes go deeper on forms, comparisons and timing.
How Oh!Mg fits
Oh!Mg is built as an evening magnesium: it pairs three forms — bisglycinate, lactate and taurate — with lemon balm, L-theanine, vitamins B6 and B5, and zinc, so it covers more than one calming pathway. For the practical details — the best forms for sleep, how glycinate compares with other forms, and how long magnesium takes to work — follow the guides linked below.
