As the United States dietary supplement and functional beverage sectors transition toward strict adherence to the Dietary Supplement Health and Education Act (DSHEA), 21 CFR Part 111 (cGMP), and increasing scrutiny under the FSMA Foreign Supplier Verification Program (FSVP), brand formulators and procurement directors can no longer rely on unverified botanical brokers. Sourcing plant-derived active ingredients demands verified botanical provenance, standardized secondary metabolite profiles determined via calibrated High-Performance Liquid Chromatography (HPLC), and preemptive compliance with strict heavy metal limits under California Proposition 65 and USP <2232>.
Xi'an Vexli Bio-Tech Co., Ltd. serves as an auditable bridge between origin botanical extraction and the high-compliance requirements of the US domestic manufacturing ecosystem. Backed by verified SGS on-site factory evaluations, CE certification standards, dual USDA & EU Organic accreditations, and patented isolation technologies, our ingredients guarantee full batch-level chemical traceability, zero adulteration, and turnkey documentation required by US customs, third-party laboratory auditors, and contract manufacturing organizations (CMOs).
Sourced directly from native botanical harvest regions, processed under ISO 22000/HACCP parameters, and fully tested for heavy metals, residual solvents, and botanical identity.
Shade-grown first harvest leaves, slow stone-milled to >1000 mesh. High L-theanine and EGCG content with zero pesticide residues compliant with BS EN 15662.
100% water-soluble natural blue protein pigment extracted from Arthrospira platensis. Stable across neutral pH formulations for premium RTD beverages and gummy supplements.
Cold-spray-dried red beet juice rich in dietary nitrates and natural betalains. Ideal for cardiovascular and pre-workout endurance blends without earthy sediment.
Turnkey retail-ready tin and pouch custom packaging options. Batch-verified polyphenol profiles with full FDA nutrition facts panel compliance for US brands.

Concentrated plant extract standardized for beta-sitosterol and scopoletin. Used widely in US prostate support formulas, urinary tract health, and hormone modulation products.
Precision-milled powders and standardized chemical extracts formulated to seamlessly integrate into US manufacturing lines without clumping, phase separation, or off-target odor profiles.
US consumers are demanding functional sodas, botanical energy drinks, and adaptogenic cold brews that eliminate synthetic FD&C dyes while maintaining striking visual identity and sustained active bioavailability.
Our phycocyanin (blue spirulina), micronized ceremonial matcha, and purple yam powders feature rapid cold-water dispersion, sub-micron particle distributions (>450 mesh), and thermal pasteurization resistance (HTST/UHT) without sedimentation or color degradation.
The US longevity, nootropic, and cellular health market requires botanical active compounds that possess verified CAS numbers, documented enantiomeric purity, and minimal crystalline variance.
Our bulk 99% NAD+, NADH, NMN, and Stinging Nettle extracts undergo triple-stage vacuum recrystallization. Every shipment provides precise bulk density metrics (0.35–0.65 g/mL) calibrated for high-speed automatic two-piece capsule filling machines and dry-blend tableting presses.
The convergence of oral nutricosmetics ("beauty-from-within") and topical clean-label personal care in the US drives high demand for pure antioxidants that soothe oxidative stress and modulate pigmentation pathways.
With cosmetic-grade Alpha-Arbutin (99%), water-soluble Sodium Copper Chlorophyllin, and concentrated astaxanthin, formulators achieve flawless emulsification across water-in-oil (W/O) and oil-in-water (O/W) bases with verified non-irritation profiles.
Technical insight on how forward-looking American brands secure their ingredient supply chains against regulatory roadblocks, adulteration scandals, and customs detentions.

Operating from the botanical heartland of Shaanxi, China, our infrastructure bridges natural raw cultivation directly to your manufacturing docks with zero broker margins.
Our extraction lines, hygiene zones, and logistics facilities have undergone strict on-site audits by SGS. We maintain audited production transparency across our 1,250 m² operational base.
We hold dual USDA Organic & EU Organic certificates, ISO 22000 Food Safety System certification, HACCP safety management, and Halal & Kosher kosher certificates for religious compliance.
We own breakthrough Invention Patent ZL 2014 1 0464649.9 and Utility Model Patent No. 14520048, which deliver improved active marker yields while dramatically reducing residual solvent markers.
Rather than sourcing volatile batches on spot markets, we maintain direct contracts with 25 specialized plantation bases, stabilizing raw material pricing, crop seasons, and assay consistency.
Our analytical bench houses HPLC (High Performance Liquid Chromatography), Gas Chromatography (GC for residual solvents), UV Spectrophotometers, and aseptic microbial incubation chambers.
From 1 kg pilot R&D lots to 20-ton ocean container contracts, we provide flexible procurement thresholds with sea, air, and expedited customs-cleared DDP shipping directly to US warehouses.
Direct answers to questions regularly asked by VP of Quality, Regulatory Affairs Directors, and Senior Botanical Buyers.
We provide complete FSVP documentation dossiers directly to your designated Qualified Individual (QI). This includes batch-specific hazard analyses (biological, chemical, and physical), flow charts, preventive control verification, our audited ISO 22000 certificate, and SGS inspection records. This guarantees rapid clearance without FDA Form 483 inspection citations.
Every lot intended for the US market is analyzed via Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Our default release specs guarantee Lead (Pb) < 0.5 ppm (often < 0.1 ppm for matcha and superfoods), Arsenic (As) < 0.5 ppm, Cadmium (Cd) < 0.2 ppm, and Mercury (Hg) < 0.1 ppm, fully satisfying USP <2232> limits without mandatory Prop 65 warning labels.
Yes. Every commercial shipment is accompanied by a batch-matched Certificate of Analysis (COA) containing exact numeric values rather than vague "conforms" statements. For purity-critical molecules like NAD+, NADH, and Alpha-Arbutin, we include the raw HPLC chromatographic integration curve verifying peak purity and retention time.
For stock powders and extracts (1 kg to 500 kg), goods are dispatched within 48 to 72 hours via air courier (FedEx/DHL/air freight) with door-to-door transit times of 4–7 business days. For multi-ton commercial production, ocean shipping to Long Beach or Newark ports is 18–25 days under FOB, CIF, or fully customs-cleared DDP terms with all ISF filings executed seamlessly.
Absolutely. We operate vibrating sieves and dynamic micronizers capable of tailoring particle size from free-flowing 80-mesh powders (for high-speed tablet and capsule compression) up to ultra-fine 450-mesh and 1000-mesh suspensions (for smooth instant dissolving drinks and matcha blends), with full bulk density customization.
Yes. We provide 50g–100g complimentary evaluation samples to verified commercial entities, contract manufacturers, and brand R&D departments. This allows internal quality teams to verify solubility, organoleptic profile, dissolution rate, and potency assay on your internal HPLC/micro lab prior to issuing purchase orders.
Submit your target specification, assay threshold, and target annual volume. Our technical regulatory team will provide complete specifications, heavy metal ICP-MS records, COA samples, and landed US quotes within 12 hours.
