Magnesium Glycinate: The Complete Guide
What magnesium glycinate is, how well it's absorbed, and how to choose one — plus why Oh!Mg builds on the bisglycinate form.
Reviewed by Dr Elena Seranova
Magnesium glycinate is magnesium bound to the amino acid glycine — a chelated form valued for being well absorbed and gentle on the stomach. It’s one of the most-searched forms of magnesium, and the one most people mean when they ask which magnesium to take in the evening.
If you’re winding down at night, glycinate is a sensible, well-tolerated default: calming rather than stimulating, and easy to take consistently.
How Oh!Mg uses it
Oh!Mg builds on magnesium bisglycinate — the fully-chelated form of glycinate — and pairs it with magnesium lactate and taurate so it covers pathways a single form can’t. For the practical differences between the forms, and what to look for on a label, see the guides linked below.
