Can You Take L-Aspartic Acid and Magnesium Together?

May affect absorption

The short answer

L-Aspartic Acid can chelate divalent cations like magnesium, forming magnesium aspartate complexes in the gut. This may reduce the bioavailability of free magnesium when taken simultaneously.

How to arrange timing

Separate L-Aspartic Acid and magnesium supplements by at least 1 hour for optimal absorption.

Important context

Whether supplements suit you together also depends on dose, product formulation, health conditions, and medication use. Ask a doctor or pharmacist first if you take medication, are pregnant or breastfeeding, or have a chronic condition.
