Generally fine together
Generally fine together; some prefer to split for tolerance.
Can I take Calcium and Magnesium Glycinate together?
Generally fine together; some prefer to split for tolerance.
How it works
The mechanism
Magnesium and calcium share some absorption pathways, but at typical supplemental doses (≤500 mg each) the interaction is small. Splitting can improve GI tolerance more than absorption.
Dose where it matters
When the interaction actually matters
Above ~1,000 mg combined, splitting into two doses is reasonable. Below that, same-meal is fine.
Evidence strength
Limited evidence
Largely traditional use or preliminary studies.
