A gentle, popular magnesium, if you can handle the tablet size
Doctor's Best uses magnesium lysinate glycinate chelate made with Albion TRAACS technology, at 100 mg per tablet. iHerb shows a 4.8 average across more than 200,000 ratings, and buyers describe it as easy on the stomach and good value for a chelated form. The most common complaint is tablet size, with some calling them horse pills. Many people take it for sleep or cramps, but sleep experts say the evidence for magnesium as a sleep aid is weak. As a well-tolerated magnesium, buyers clearly keep coming back.

What the research and experts say
Magnesium is often taken for sleep, but AARP reports that it is not an established insomnia treatment and is not recommended by the American Academy of Sleep Medicine. Sleep specialists point to only one significant study, from 2002 with 12 older adults, and a 2021 meta-analysis called the evidence for older patients substandard. One neurologist quoted calls magnesium cheap and low risk, but that is clinical experience, not trial evidence.
Dose matters for comfort. ConsumerLab notes that doses over 350 mg raise the risk of diarrhea and other side effects. In its test of 15 magnesium supplements, two were not approved because they appeared to contain a different form than labeled. Doctor's Best was tested, but the per-product result is members-only. iHerb labels the product independently third-party tested without naming a lab.
People with kidney problems or on prescription medicines should check with a clinician before taking magnesium.
Tips from buyers
- Take it with food if your stomach is sensitive.
- Start with two tablets and see how you feel before taking more.
- Split doses between morning and evening, as the label allows.
- Look at capsule versions if the tablet size is a problem.
