Proven Safe. Proven Stable. Globally Compliant.
For nutraceutical brands, an ingredient is only as trustworthy as the evidence behind it. At Youyou Biotechnology, safety, stability and international compliance are not marketing claims — they are engineered into every molecule we manufacture, and documented for every batch we ship.
Since 2014, Youyou Biotechnology has specialized in the research, development and manufacturing of high-purity nutraceutical ingredients. Guided by our principle of "Quality First, Reputation Foremost," we have built a quality system that answers one question before any product reaches the market: can this batch be fully proven safe, stable and compliant?
Safety — Engineered from the Molecule Up
🧪 Raw Material Control
Every incoming raw material — from starting reagents to packaging — is inspected and qualified against approved specifications before use. Suppliers are audited and re-qualified on a regular schedule, and materials stay quarantined until released by QC.
|
⚗️Controlled Synthesis
Our controlled chemical synthesis platform — protected by 10 patents and proprietary technologies, including the U.S.-patented BerVic® Berberine Vitamin C Salt (US 11,345,697 B1) — is designed to minimize impurities and residual solvents from the start.
|
🔬 Full-Panel Testing
Each batch is tested with validated methods: assay and purity by HPLC, heavy metals and elemental impurities by ICP-MS, residual solvents by GC, structural identification by HNMR, plus moisture, particle size and microbiology as required.
|
Stability — Consistency You Can Measure
📈 Real-Time Process Control
Critical process parameters are monitored in real time throughout synthesis, purification and drying. In-process samples are taken at defined checkpoints; every deviation is documented, investigated and corrected before the batch moves forward.
|
⏱️ICH-Aligned Stability Programs
Accelerated and long-term stability studies are conducted in line with ICH guidelines, generating real-time data that defines shelf life, storage conditions and packaging requirements — not estimates.
|
🔄 Batch-to-Batch Consistency
Our ingredients have passed years of mass production, formulation trials and global market application. Three production bases run under one unified quality system, delivering consistent batch-to-batch quality at scale.
|
Compliance — Standards Your Market Requires
|
📄 Complete Documentation
Every shipment is supported by the documents your quality team needs: Certificate of Analysis, batch production records, deviation reports, and stability data — plus COA, MSDS, TDS and customized compliance dossiers on request.
|
🔗 Full Traceability
Every batch is traceable from raw-material lot to finished goods. When you ask "where did this come from and how was it made?", we can answer with records — not anecdotes.
|
🤝 Audit-Ready
From regulatory filings to on-site audits, our quality documentation is maintained to support your own registration and compliance requirements across global markets.
|
Our promise: every batch, verified. Every shipment, documented. If you are formulating with BerVic® Berberine Vitamin C Salt, Paraxanthine, Urolithin A, Dihydroberberine, Spermidine or any of our functional ingredients — the evidence travels with the product.
