Doctor's Best magnesium glycinate lysinate - 240 tablets, 200 mg per serving
Doctor's Best High Absorption is one of the most-reviewed magnesium glycinates on Amazon. A 240-tablet bottle costs about $24 and averages 4.6 stars from around 76,600 reviews.
What's in it
The listing gives 200 mg of magnesium per serving, as a glycinate lysinate chelate. Chelated means the magnesium is bound to amino acids, glycine and lysine in this case. Doctor's Best says it's easy on the digestive tract and can be taken any time of day. It also says it's vegan, non-GMO, gluten-free and soy-free, with no fillers or buffering.
Check the Supplement Facts panel for how many tablets make a serving and the exact magnesium amount. That's the figure that counts toward your daily limit.
The claims, sorted
The "up to 6x better absorption" line doesn't say what it's being compared against, so don't read much into it. The sleep claims also need context. The evidence that magnesium improves sleep is limited and mixed. It may help people who are low in magnesium to begin with. If your levels are already fine, a supplement may do very little. Our magnesium for sleep guide goes through the research and the different forms.
Dietary supplements aren't approved by the FDA for safety or effectiveness before they go on sale. Third-party quality marks such as USP Verified are one signal of quality; this listing doesn't mention one.
How much is too much
The NIH Office of Dietary Supplements sets the upper limit for supplemental magnesium at 350 mg a day for adults. Magnesium from food doesn't count toward that. One 200 mg serving is under the limit, but add up anything else you take, such as a multivitamin or a sleep blend that also contains magnesium.
Check with your doctor or pharmacist before starting, especially if you have kidney disease or take regular medication.
Who it's for
- Adults who want a plain glycinate with no added sleep blend
- People who want a large bottle at a low cost per serving
Who should skip it
Anyone who would rather take a supplement with a third-party quality mark. The Nature Made Magnesium Glycinate 300 mg is USP Verified according to its listing, at about $23 for a 30-day supply. If you want a smaller, cheaper bottle to try first, the Nature Made 200 mg, 60 capsules is about $12.
