Functional Peptides
Functional Peptide Supplier for Global B2B Buyers
Where can I source functional peptides from China?
AICHENGFU supplies marine collagen peptides, bovine collagen peptides and plant protein peptides for supplement brands, functional food manufacturers, beverage developers, beauty-from-within formulas and sports nutrition applications. Every shipment includes batch-specific documentation support.
What are functional peptides?
Functional peptides are bioactive protein fragments produced through controlled enzymatic hydrolysis. They are shorter than whole proteins, which typically results in better bioavailability and faster absorption. Functional peptides are commonly used in supplement, food, and beverage formulations targeting areas including skin health, joint support, sports nutrition, and gut health.
The molecular weight of peptides determines their functionality. Lower molecular weight peptides (below 3000 Daltons) are generally more bioavailable and dissolve more readily in water, making them suitable for beverages and fast-absorbing supplements. Higher molecular weight peptides may be preferred for sustained release applications.
AICHENGFU supplies both animal-sourced peptides (marine collagen, bovine collagen) and plant-sourced peptides (soy, pea, rice, walnut, corn). This allows buyers to select ingredients that match their target consumer profile, whether that requires marine-sourced beauty ingredients or vegan-friendly sports nutrition options.

Functional Peptide FAQs
Common questions from B2B buyers about sourcing functional peptide ingredients.
AICHENGFU supplies export-ready functional peptide ingredients for global B2B buyers. Our portfolio includes marine collagen peptides, bovine collagen peptides, and plant protein peptides (soy, pea, walnut, corn, rice). We provide documentation support including COA, TDS and MSDS for supplement brands, functional food manufacturers and beverage developers in UK, EU, USA, Australia and 40+ countries.
Collagen is a large protein molecule, while collagen peptides (also called hydrolysed collagen) are smaller chains of amino acids produced through enzymatic hydrolysis. Collagen peptides typically have molecular weights between 500-5000Da, making them more bioavailable and easier to incorporate into formulations like powders, drinks and capsules.
Functional peptides are used in beauty-from-within supplements, sports nutrition products, joint and bone health formulations, weight management products, functional beverages, and healthy aging formulas. The specific application depends on the peptide source and molecular weight profile. Marine collagen is commonly used in beauty applications while plant peptides suit vegan sports nutrition.
Lower molecular weights (500-2000Da) are typically preferred for applications requiring rapid absorption such as beauty drinks and sports recovery. Higher molecular weights (2000-5000Da) may be suitable for sustained release applications. AICHENGFU can advise on the optimal specification for your target application and formulation format.
For peptide ingredients, buyers should request Certificate of Analysis (COA) showing molecular weight distribution and protein content, Technical Data Sheet (TDS), Material Safety Data Sheet (MSDS/SDS), allergen statement, and origin documentation. AICHENGFU can provide these documents depending on product, grade and batch.
Yes, most functional peptides from AICHENGFU are water-soluble across a wide pH range. For beverage applications, we recommend peptides with molecular weight below 3000Da for optimal cold-water solubility. We test solubility characteristics and can provide data sheets for beverage formulation support.
Minimum order quantities vary by product and grade. AICHENGFU offers flexible MOQ options from sample quantities for development through to bulk orders for production.
