THORNE Magnesium Glycinate is a premium supplement designed for individuals seeking optimal magnesium absorption without gastrointestinal discomfort. This product is ideal for those who struggle with sleep quality, muscle tension, or stress, as well as athletes looking to support recovery.
The standout feature is its chelated form: magnesium bound to the amino acid glycine. This enhances bioavailability and reduces laxative effects common with other magnesium types. In real-world use, users often report improved sleep onset and reduced muscle cramps within a week of consistent intake.
Thorne's manufacturing adheres to strict quality controls, including third-party testing for purity and potency. The capsules are free from common allergens and artificial ingredients, making them suitable for sensitive individuals. While the bottle contains 90 capsules, the recommended dosage typically ranges from one to three per day depending on individual needs.
Potential drawbacks include a higher cost per serving versus generic brands, and the need for multiple capsules to achieve 400 mg of elemental magnesium. Additionally, as a newer listing, there are currently no customer reviews to validate real-world experiences, so buyers rely solely on Thorne's established reputation.
Overall, THORNE Magnesium Glycinate is a top-tier choice for those prioritizing absorbability and purity. If you value a clean, effective supplement and are willing to invest in quality, this product delivers on its promises without compromising digestion.
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

- Some users may prefer a higher dose per tablet.
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.

Buying Guide
Form and Absorption
The form of magnesium you choose directly affects how well your body uses it. Magnesium bisglycinate, found in Thorne products, is chelated to glycine, a calming amino acid. This form is gentle on the stomach and highly absorbable, making it ideal for sleep and stress relief. In contrast, Doctor’s Best often uses magnesium glycinate or oxide, which may have different absorption rates. For those who want a targeted approach, understanding the difference between powder and capsules can matter. Read our sleep powder vs capsules guide for more insights.
Purity and Third-Party Certification
Quality assurance matters, especially with supplements you take daily. Thorne products are NSF Certified for Sport, meaning they have been verified for label accuracy and screened for over 280 banned substances. This makes them a trusted choice for athletes and health-conscious users. Doctor’s Best also follows good manufacturing practices, but Thorne’s rigorous third-party certification adds an extra layer of confidence. If you value purity and transparency, Thorne leads.
Intended Use and Lifestyle Fit
Not all magnesium supplements serve the same purpose. Thorne Magnesium Bisglycinate powder is designed for whole-body wellness and restful sleep, while the glycinate capsules focus on stress relief and mental clarity. Consider your primary goal: sleep, recovery, or targeted health support. For those exploring natural sleep aids, our article on ashwagandha and magnesium for sleep offers additional guidance.
Servings and Convenience
How you take your supplement matters. Thorne offers both a powdered form (60 servings per container) and capsules (90 or 180 count), giving you flexibility. Powders mix easily into water or smoothies and may be better for those who dislike swallowing pills. Capsules are convenient for travel or busy schedules. Doctor’s Best typically provides capsules, but Thorne’s variety lets you choose what fits your lifestyle.
