Free · No account · based on published sources including NIH ODS, FDA drug labels, and peer-reviewed literature
Consume magnesium-rich foods (leafy greens, nuts, seeds) and consider supplementing with 200–400 mg/day of magnesium glycinate or magnesium citrate, as these forms have better GI tolerability. Avoid magnesium oxide if GI side effects are present. Monitor for muscle cramps, fatigue, or cardiac arrhythmias.
Why this interaction occurs
Patients on GLP-1 agonists frequently experience nausea, vomiting, and diarrhea, all of which increase magnesium losses through the GI tract. Simultaneously, reduced food intake diminishes dietary magnesium. Magnesium is essential for over 300 enzymatic reactions including glucose metabolism, neuromuscular function, and cardiovascular regulation. Hypomagnesemia may also worsen insulin resistance, counteracting GLP-1 therapeutic goals.
