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.

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
Absorption and Bioavailability
Magnesium glycinate is widely regarded as one of the most absorbable forms of magnesium. Doctor’s Best uses a patented chelated form called magnesium glycinate lysinate, which they claim offers up to six times better absorption than standard magnesium glycinate. Pure Encapsulations also uses magnesium glycinate, but without the added lysine. For most people, both forms are highly bioavailable and gentle on the stomach. If you have a sensitive digestive system, either option should work well, but the lysinate addition in Doctor’s Best may give a slight edge in absorption for those with deficiencies.
