Premium Lactoferrin Peptide Powder – High-Purity Bioactive Ingredient with Superior Stability for Functional Nutrition & Skincare
Xi'an Jiayuan Bio-tech Co., Ltd., established in 2002 with RMB 30 million registered capital, specializes in producing pharmaceutical-grade Lactoferrin Peptide derived from goat's milk. Our product is ≥95% pure and has a molecular weight of 1,000-5,000 Daltons which increases the bioavailability against the natural 80 kDa lactofer We have 30 technical personnel, two GMP manufacturing lines, and ISO9001, SGS, HALAL certifications to guarantee quality control. The product has a thermal stability up to 90°C and a water solubility at pH 2.0-9.0 and therefore an excellent functional ingredient for nutritional supplement, cosmeceuticals and oral care.

What Is Lactoferrin Peptide?
This product demonstrates the enzymatic degradation of natural lactoferrin with bioactive short chain peptides such as Lfcin and Lactoferrampin. Cationic and amphipathic peptide fragments have a higher membrane penetration ability than lactoferrin proteins.
Your formulations are free from stomach degradation issues because of the low molecular weight profile. This makes the chemical especially useful when you need sustained bioactivity in acidic settings or requires skin penetration for topical use.

Functions
Due to its unique structural features our product has a number of biological benefits:
Antimicrobial Activity The high net positive charge allows for electrostatic attraction to negatively charged bacterial membranes, which leads to the disruption of bacterial cell walls (e.g., Cutibacterium acnes and Streptococcus mutans).
Immunomodulation Support Bioactive peptides help regulate immune signalling and reduce pro-inflammatory cytokines (IL-6, TNF-α) to make your formulation anti-inflammatory.
Enhanced Absorption: The pre-digested peptide structure allows for higher absorption rates compared to intact proteins, ensuring functional advantages are delivered effectively to your end consumers.
Process Stability: Heat resistance maintains activity during pasteurisation and high temperature processing, limiting dangers of formulation reformulation.

Application Fields
Functional Nutrition & Dietary Supplement: Add to baby formula, immune support capsules and protein powders if stomach stability is a concern. The peptide withstands the acidity and delivers immune enhancing fragments to the sites of intestinal absorption.
Cosmeceuticals & Dermatology: Design cutting-edge anti-acne serums, barrier repair creams, and solutions for sensitive skin. This peptide penetrates the stratum corneum well, attacking the acne bacteria and decreasing irritation and redness.
Oral Hygiene Products: Develop therapeutic mouthwashes and high-end toothpastes with biofilm prevention properties. Active in surfactant rich formulations even, reducing periodontal problems and production of caries.

FAQ
Q: How is this product different from complete lactoferrin protein?
A: The peptide form has a reduced molecular weight (1,000-5,000 Da vs. 80,000 Da), greater stomach stability, higher membrane penetration and improved heat resistance, all of which are key benefits for formulation performance.
Q: How much may I use in my formulations?
A: Generally, topical use is in the range of 0.1%-2% and dietary supplement use is in the region of 50-200 mg per dose, depending on what advantages you are trying to get. We provide you technical advice for your particular application.
Q: Do you have sampling testing?
A: Yes, we are able to provide samples, as well as COA documents so that you may examine quality and compatibility before large purchases.
Q: How do you maintain consistency across batches?
A: We use HPLC fingerprinting to standardise the peptide markers and our ISO certified quality systems to oversee the selection of raw materials to final inspection to ensure repeatable biological activity.
