PEPDOO® Nano Fish Collagen Peptide: Pure, Patented, Powerful
Premium Fish Collagen Peptides with Patented Enzymatic Technology
PEPDOO® Fish Collagen Peptides (Patent No. ZL201310642727.5) are derived through a patented enzymatic hydrolysis process that ensures high purity, strong bioactivity, and environmental sustainability.
By fully filtering the hydrolysate to remove residues, and using advanced multi-stage enzymatic digestion and separation technologies, we obtain bioactive oligopeptides with concentrated molecular weight distribution and excellent solubility. Our collagen peptides are refined into a delicate white powder with reduced bitterness and odor through physical deodorization techniques.
Produced via a fully automated and intelligent enzymatic control system, the peptides retain strong antioxidant and anti-tumor properties. Free from acid or alkali treatment, this green process minimizes environmental impact while maximizing functional benefits.

Clinically Proven Effects of Hydrolyzed Collagen Peptides Across Key Health Areas
A double-blind, randomized, placebo-controlled clinical trial showed that participants who consumed a blend of collagen bioactive peptides and antioxidants for 90 days experienced a 7.5% improvement in skin elasticity compared to the placebo group.

In vitro studies on MC3T3-E1 osteoblast cells revealed that fish collagen peptides significantly enhance cell proliferation and promote the secretion of Type I collagen. The effect was more pronounced with smaller molecular weight peptides, suggesting their strong potential in supporting bone health and preventing osteoporosis.

A study using a mouse skin wound model demonstrated that low-dose fish collagen peptides had no significant effect on wound healing, while medium and high doses significantly enhanced wound closure rates. Fish collagen peptides from sea bass accelerated skin wound healing by reducing inflammation, promoting granulation tissue formation, and stimulating collagen production, leading to faster recovery.
Additionally, a double-blind trial with healthy women experiencing thinning hair showed that collagen supplementation improved overall hair volume, scalp coverage, and hair thickness after 90 days.
PEPDOO® Fish Collagen Peptides Product Parameters
PEPDOO® Fish Collagen Peptides are produced using a patented technology that combines multi-enzyme hydrolysis and nano-purification processes to create ultra-small molecular peptides. These peptides have a low molecular weight, which allows for excellent absorption and makes them easy to incorporate into various products.
The product has a pleasant taste, with no fishy or bitter flavor, ensuring broad applications across diverse formulations. It is highly stable, with no changes in protein structure under heat or acidic conditions. Additionally, the peptides dissolve quickly in water, forming a clear, impurity-free solution. Due to the low molecular weight, the viscosity remains consistent even with concentration changes.
PEPDOO® Fish Collagen Peptides are ideal for use in health supplements, functional foods, beverages, and skincare products. The product is available in 1kg and 20kg packaging, with a shelf life of 24 months under proper storage conditions.
