Magnesium Bisglycinate 200 mg by Thorne

If you’re searching for magnesium glycinate for sleep, this fits adults who want a gentle, absorbable form that doesn’t upset the stomach. It’s useful if your Magnesium, RBC (magnesium inside red blood cells, a better gauge of body stores than serum) is low or low-normal, if you train hard and cramp at night, or if stress tightens your neck and jaw by evening. People on acid-reducing meds or diuretics often run low and notice calmer sleep within 1–2 weeks.

Magnesium bisglycinate pairs magnesium with two glycine molecules, improving absorption and making it easier on the gut than oxide or citrate. Magnesium helps nerves and muscles reset after firing, which is why tight calves and restless legs often ease. It also tamps down NMDA receptors (excitatory switches in the brain) and supports GABA signaling (your brain’s “brake pedal”), which together explain better sleep quality and reduced nighttime awakenings in responders.

Mix one stick with at least 8 ounces of water daily. Take with or without food; evening is practical if sleep is your goal. Most adults use 200–400 mg elemental magnesium per day across diet and supplements, so this serves as a single daily dose or part of a split regimen. Glycinate is less likely to loosen stools, but if you’re sensitive, start with half a stick for 3–4 days, then increase. Recheck Magnesium, RBC after 8–12 weeks.

Take magnesium glycinate at least 2 hours apart from levothyroxine, fluoroquinolone or tetracycline antibiotics, and bisphosphonates because it can reduce their absorption. If you have significant kidney disease, skip self-supplementation and work with your clinician. Magnesium can modestly lower blood pressure; if you’re on antihypertensives, monitor at home. For migraine prevention or frequent muscle cramps, pair with checking Magnesium, RBC and address low intake from diet first.
