Doctor’s Best High Absorption Magnesium Glycinate
Magnesium glycinate is one of the most studied, best-tolerated forms of magnesium for winding down before bed. Doctor’s Best pairs it with BioPerine for absorption, and it is rated above 4.5 stars by more than 75,000 Amazon buyers (check the current figure on Amazon).
- Well-tolerated form — magnesium glycinate is gentler on the stomach than magnesium oxide or citrate, so it’s less likely to cause the laxative effect some cheaper magnesium supplements are known for.
- Third-party tested and produced in a GMP-certified facility in the US.
- 120 capsules per bottle — about a two-month supply at the standard 2-capsule serving.

Who it suits — and who should skip it
This suits someone taking magnesium for sleep or muscle cramps who has had trouble with the cheaper forms. Glycinate is chelated to an amino acid, which is why it is the form usually recommended when stomach upset has been the problem. · Hatch Restore 3 sunrise alarm
Skip it if capsule size is a deal-breaker — reviews on that point are mixed, and a few buyers find the capsules larger than expected. Skip it too if you have kidney problems: magnesium supplementation is a doctor conversation in that case, not a shelf decision.
Taking it usefully
- Take it in the evening if sleep is the reason you bought it. There is no benefit to splitting it across the day for most people.
- Give it a fortnight before judging. Magnesium is not a sedative and does not work on the first night.
- Check what else you take. Magnesium can interfere with the absorption of some medicines, including certain antibiotics.
Why the form on the label matters
Magnesium oxide is the cheapest and most common form on supermarket shelves, and it is also the one with the poorest absorption and the highest chance of a laxative effect — which is why so many people conclude that magnesium “does not agree with them”. Glycinate and citrate absorb better and sit easier. If you have tried magnesium before and stopped, the form is the first thing to check on the old bottle.
