OEM Customization & Contract Services
Custom Standardizations: While 98% 5-HTP is our standard, we can manufacture lower concentrations (e.g., 20% or 50% 5-HTP) for unique product applications requiring a larger whole-herb footprint or specialized herbal complexes.
Advanced Particle Engineering: Available in ultra-fine micronized powders for instant water solubility or granular forms optimized for seamless flow and high-density compression on high-speed tableting presses.
Turn-Key Finished Dosage Customization: Partner with our contract manufacturing lines to create ready-to-sell finished products under your private label, including custom-flavored tablets, precision-filled capsules, or functional sleep gummies.


Quality Assurance
Facility Accreditations: Manufactured in a facility certified under ISO 9001, ISO 22000, HACCP, and cGMP standards, along with a valid FDA registration.
Complete Traceability Package: Every batch ships with a comprehensive Certificate of Analysis (CoA), SDS, Non-GMO Statement, Allergen-Free Declaration, and BSE/TSE-Free Certification.
Third-Party Lab Verification: Routine validation via independent, ISO 17025 accredited third-party laboratories (such as Eurofins or SGS) ensures total transparency for active purity and microbial safety.
Factory,Packaging

1–3 kg: Double-layer, moisture-proof aluminum foil bags with heat-sealed closures.

FAQ
Q: How do you verify that your Griffonia Seed Extract is entirely natural and not spiked with synthetic 5-HTP?
A: We use carbon isotope ratio analysis ($^{14}\text{C}$ testing) and high-performance liquid chromatography (HPLC) peak identification. This allows us to trace the botanical footprint precisely and guarantee our extract is 100% natural, derived solely from Griffonia simplicifolia seeds.
Q: What is Peak X, and how do you test for it?
A: Peak X is an unwanted impurity historical associated with poor-quality tryptophan manufacturing. We test every single commercial batch of our Griffonia Seed Extract via advanced HPLC and mass spectrometry methods to guarantee that Peak X is completely non-detectable ($<0.001\%$).
Q: Can this extract powder be utilized effectively in dietary gummies?
A: Yes. Our premium 98% 5-HTP is ideal for gummies because its high purity means you require very low inclusion weights per gummy to meet the active dose. This minimizes any potential impact on the gelling matrix, taste profile, or clarity of the gummy.
Q: Do you offer free samples for active R&D testing?
A: Yes, we supply complimentary samples (typically 50g to 100g) to verified commercial businesses, supplement brands, and contract manufacturers for laboratory and pilot-scale testing. Contact our sales department to arrange your sample shipment.
