I started taking over-the-counter Nexium (esomeprazole magnesium 20mg/capsule) a few days ago and may be taking them for at least the next 2 weeks. My blood magnesium levels were low a few weeks ago and they just got back to normal right before I started taking the Nexium. I've been taking Naxium in the evening (4-5pm) at least an hour before having dinner. I typically supplement with magnesium sulfate (epsom salt, 1/4-1/2 tsp at a time) and/or magnesium glycinate (one 200 mg tablet at a time) and occasionally powdered magnesium citrate.
I've read that PPIs inhibit magnesium absorption, so would it help to take the magnesium supplements in the morning if I'm taking the Nexium at night? Thanks!
