Core Bioactive Portfolio
Primary Engineered Peptides & Nutritional Precursors
Direct factory allocation of lab-verified peptides, botanical fractions, and structural active compounds engineered for top-tier dietary and cosmeceutical formulations.
Biochemical Rigor & Technical Characterization
What Defines the "Most Effective" Collagen Peptides?
Commercial efficacy is governed entirely by enzymatic site-specificity, Daltons molecular-mass distribution, and post-hydrolysis tripeptide concentration (Pro-Hyp and Hyp-Gly).
<1000 Da
Ultra-Low Dalton Mass
≥95%
Intestinal Permeation Rate
3,000 t
Annual Scalable Throughput
100%
Full Batch Cold-Chain Integrity
Enzymatic Endopeptidase Cleavage
Unlike crude thermal or acid hydrolysis that denatures amino acid structures into unfunctional ash, our multi-stage targeted enzymatic cleavage preserves the bioactive dipeptides and tripeptides (Gly-Pro-Hyp) essential for direct transport across PEPT-1 enterocytes.
Narrow Chromatographic Fingerprint
We calibrate our ultrafiltration membranes to achieve more than 85% of oligopeptides strictly between 500 Da and 2,000 Da. This tight distribution ensures zero gastric precipitation and maximum bio-accessibility in oral nutricosmetics and clinical recovery fluids.
Organoleptic Neutrality & Cold Solubility
Patented nano-filtration and dynamic decolorization remove high-threshold volatile odor amines, yielding crystal-clear reconstitution even at 15% solids concentration in cold water (4°C) with zero organoleptic interference.

Procurement Intelligence
Frequently Asked Questions for Formulation & Sourcing Heads
Direct answers to technical, logistical, and compliance questions faced by industrial procurement teams.
What specific molecular weight cut-off qualifies collagen as "most effective"?
Peer-reviewed scientific data indicates that peptides below 2,000 Daltons—and ideally clustered under 1,000 Daltons—bypass common gastric breakdown and cross the intestinal barrier intact via the oligopeptide transporter PEPT-1. This allows bioactive Pro-Hyp (prolyl-hydroxyproline) and Hyp-Gly directly into human plasma to trigger collagen neo-synthesis in dermal fibroblasts.
How does Xi'an Le-Nutra ensure batch-to-batch organoleptic neutrality?
Our multi-stage downstream purification leverages dual-phase activated carbon decolorization, flash vacuum deaeration, and precise ceramic nano-filtration. This eliminates typical sulfur and lipid peroxidation residues, producing fine white powders that dissolve clear and neutral in cold water, making them ideal for high-end nutricosmetics and premium drinks.
What are the standard lead times and Minimum Order Quantities (MOQ)?
Our baseline commercial MOQ starts at 25 kg (pharmaceutical-grade fiber drums with double PE inner liners). For tailored custom specs (such as custom mesh sizes, agglomeration, or distinct molecular weight brackets), the MOQ is typically 500 kg. With 3,000 tons annual capacity, standard inventory orders ship within 3–5 working days from our Xi'an central warehousing.
What documentation accompanies export orders for regulatory customs clearance?
Every shipment arrives with batch-specific Certificates of Analysis (COA) containing HPLC/spectrophotometric assay, full microbial test profiles, and heavy metal counts (ICP-MS). We also provide Safety Data Sheets (SDS), Non-Irradiation declarations, BSE/TSE-free certifications, Allergen statements, and origin certificates for tariff preference programs.
Can Le-Nutra produce custom agglomerated, instantized, or premixed peptides?
Yes. We operate fluid-bed agglomeration units that create instantly soluble, free-flowing granules with enhanced wettability and minimal dusting. We can also dry-blend collagen peptides with synergistic micronutrients like Vitamin C, zinc gluconate, hyaluronic acid, or botanical extracts according to your proprietary master formulation.
