Pros
- High absorption rate ensures you get more magnesium per dose.
- Easy on the digestive tract, suitable for sensitive stomachs.
- Pure formulation without unnecessary additives.
- Supports both sleep quality and muscle function.
- Trusted brand with long-standing reputation for quality.
Cons

Doctor's Best High Absorption Magnesium Glycinate Lysinate is a premium magnesium supplement designed for maximum bioavailability and digestive gentleness. This formula combines magnesium with the amino acids glycine and lysine to create a chelated compound that the body can absorb up to six times more effectively than standard magnesium oxide. It is an excellent choice for individuals looking to support restful sleep, muscle relaxation, and overall stress management.
The standout feature of this supplement is its advanced chelation process, which ensures the magnesium is easily transported into cells without causing gastrointestinal upset. Many users report improved sleep quality and reduced muscle tension within a few days of consistent use. The 200mg per serving is a moderate yet effective dose, suitable for most adults as part of a balanced supplement regimen.
Doctor's Best prioritizes purity with this product. It is vegan, non-GMO, gluten-free, and soy-free, making it accessible to a wide range of dietary preferences. The 240-tablet bottle provides a long-lasting supply, and the tablets are uncoated and easy to swallow. The brand's 35+ year commitment to science-backed formulations adds credibility.
One potential drawback is that each tablet delivers only 200mg of elemental magnesium, so those needing higher doses may need to take two or more tablets per day. Additionally, while the chelated form is gentle, a small subset of users might still experience mild digestive changes. The price point is competitive for a high-quality chelated magnesium product.
Overall, Doctor's Best High Absorption Magnesium Glycinate Lysinate is a reliable, well-researched supplement that delivers on its promises of enhanced absorption and stomach comfort. It is highly recommended for anyone seeking to improve sleep, muscle recovery, and overall magnesium levels without harsh side effects.

Buying Guide
Form and Absorption: Glycinate vs Bisglycinate
Magnesium glycinate is known for high absorption and gentle digestion. Doctor’s Best uses a unique magnesium glycinate lysinate complex (chelated with both glycine and lysine) to enhance uptake. Their formula claims up to 6x better absorption compared to standard glycinate. Nature Made uses magnesium bisglycinate, a double-glycine chelate, which also offers excellent bioavailability. For most people, both are highly absorbable, but the lysine addition in Doctor’s Best may provide extra support for muscle repair. If you’re looking at other glycinate options, our Thorne vs Nature Made comparison details another top contender.
Potency and Serving Size
Doctor’s Best delivers 200 mg of elemental magnesium per serving (two tablets). Their 120- and 240-count bottles provide flexibility for a 60- or 120-day supply at that dose. Nature Made requires three capsules to deliver 300 mg of elemental magnesium. This higher per-serving dose might appeal to those needing extra support, but it also means you take more capsules. For reference, the standard RDA for magnesium is around 400 mg daily, so either product can help fill a gap. Consider your magnesium intake from food when choosing.
Ingredient Purity and Certifications
Doctor’s Best is vegan, non-GMO, gluten-free, and soy-free. Their formula contains no fillers or flow agents—just the active chelate. Nature Made is verified by USP, which confirms purity and potency. It’s also gluten-free and contains no artificial colors or flavors. Both brands are rigorous with quality control. If you have specific dietary restrictions, Doctor’s Best has a slight edge for being free of common allergens. However, Nature Made’s USP certification is a robust third-party seal of quality.
Brand Reputation and Special Considerations
Doctor’s Best has over 35 years of supplement research and is known for innovative chelates. Nature Made is the #1 pharmacist-recommended vitamin brand and has been trusted for over 50 years. Both are excellent. While not a magnesium product, if you deal with bladder issues alongside magnesium deficiency, it may be worth exploring separately. For overall wellness, combining magnesium with other sleep aids like valerian root works well—read our valerian root sleep guide.
Final Thoughts
Both Doctor’s Best and Nature Made offer high-quality magnesium glycinate, but your choice depends on what you prioritize. If you want maximum absorption per milligram with a clean, vegan formula, go with Doctor’s Best High Absorption Magnesium Glycinate. It’s ideal for those who need a potent, allergen-free product for sleep and muscle relaxation. If you prefer a higher total dose per serving with the reassurance of USP verification, choose Nature Made Magnesium Glycinate 300 mg per 3. It’s perfect for anyone wanting a trusted, pharmacist-recommended brand that supports nerve and heart health. Whichever you pick, both will serve you well in 2026.
Frequently Asked Questions
Which is better for sleep, Doctor’s Best or Nature Made Magnesium Glycinate?
Both are effective for sleep because glycinate is highly absorbable and binds to GABA receptors. Doctor’s Best’s lysine addition may offer a slight edge for muscle relaxation, but many users find Nature Made equally helpful. Pairing magnesium with ashwagandha can boost sleep benefits—see our ashwagandha and magnesium combo guide.
How much magnesium glycinate should I take daily?
The recommended dietary allowance for magnesium is 400 mg for most adults, but this includes food sources. A typical supplement dose is 200 to 300 mg of elemental magnesium daily. Doctor’s Best provides 200 mg per serving, while Nature Made gives 300 mg. Start with the lower dose and increase if needed, but do not exceed 500 mg from supplements without consulting a doctor.
Is magnesium glycinate good for anxiety?
Yes, magnesium glycinate supports the nervous system and can help reduce anxiety. Glycine itself has calming effects. Many users report feeling less stressed and more relaxed after a few weeks of consistent use. For persistent anxiety, combine magnesium with other evidence-based approaches like therapy or adaptogens.
Can I take magnesium glycinate with other supplements?
Generally yes, but be mindful of interactions. Magnesium can interfere with certain antibiotics and blood pressure medications. It pairs well with vitamin D, vitamin K2, and calcium. If you take multiple supplements, space them apart. For more on supplement stacking, browse our comparisons section for expert guidance.
