5-HTP (100 mg)
Thorne is the gold standard for purity, providing a clean 5-HTP formula without unnecessary flow agents like magnesium stearate. Their rigorous testing for 'Peak X' contaminants—a historical concern with 5-HTP—makes this the safest choice for long-term sleep support.
Quality & Materials
Contains 100mg of 5-Hydroxytryptophan sourced from Griffonia simplicifolia. Uses a leucine-based flow agent instead of synthetic stearates.
Evidence & Testing
Thorne is a frequent collaborator with the Mayo Clinic for clinical trials. Their facility is NSF Certified for Sport and TGA (Australia) certified.
Brand Transparency
Full label disclosure; manufacturing occurs in an NSF-registered facility with transparent sourcing for all botanical extracts.
Value Assessment
Priced at the premium end ($0.47/serving), but justified by the lack of fillers and the intensive contaminant screening.
Why Not Alternatives?
Unlike many competitors who use lower-quality sourcing or include stearates that may interfere with absorption, Thorne uses only high-bioavailability Griffonia extract and undergoes four rounds of testing for every batch.
