Quality & Materials

Contains 200mg Magnesium Bisglycinate, 100mg L-Theanine (as Suntheanine), 50mg 5-HTP (from Griffonia extract), and 1.5mg Melatonin. This ratio targets both sleep onset and sleep architecture.

Evidence & Testing

Ingredients like Suntheanine have multiple RCTs supporting their role in reducing sleep latency. Thorne is one of the few brands that undergoes rigorous third-party testing for every batch.

Brand Transparency

Thorne provides comprehensive transparency regarding their sourcing and manufacturing in an NSF-certified facility. No hidden fillers or artificial colors.

Value Assessment

At roughly $0.80 per serving, it is priced at a premium, but the quality of the chelated magnesium and the NSF certification justify the cost for those prioritizing safety and efficacy.

Why Not Alternatives?

Unlike many competitors that use cheap Magnesium Oxide or proprietary blends that hide dosages, Thorne uses highly bioavailable Bisglycinate and fully discloses every milligram. It avoids the 'kitchen sink' approach of 20+ underdosed ingredients in favor of four clinically backed compounds at therapeutic levels.
