Mechanism

Magnesium supplements can add a small blood-pressure-lowering effect and, at high doses in renal impairment, raise serum magnesium.

What to do

Typical doses are fine. Discuss with your prescriber if you have reduced kidney function.

How to fit both into one day

Magnesium glycinate
eveningflexible

Magnesium supports parasympathetic tone and muscle relaxation, so evening dosing also helps sleep. Keep it two hours from antibiotics and thyroid medication.

ACE inhibitor
morningflexible

Take at a consistent time each day. Do not add potassium supplements without checking potassium and kidney function.

Putting Magnesium glycinate in the evening and ACE inhibitor in the morning satisfies the 0-hour separation without disrupting either one's absorption window.
