Timing SensitiveEmerging evidence
What is happening. Magnesium/aluminum antacids can reduce mycophenolate absorption and lower mycophenolic acid exposure; ordinary magnesium supplements are less directly studied but should not be taken simultaneously without transplant-team instructions.
Mechanism. Antacid effects can reduce systemic mycophenolic acid exposure; direct binding with magnesium glycinate is less certain than with magnesium/aluminum hydroxide antacids.
Recommendation. Separate magnesium-containing products from mycophenolate by at least 2 hours unless the transplant team gives different instructions.
TimingTiming & separation.
Space the doses apart by at least this window to avoid the conflict.
