Product description
Hydrolyzed donkey collagen is produced by enzymatic hydrolysis, breaking down the collagen into smaller peptides. This process alters the molecular structure and weight of the collagen, resulting in a molecular weight that is lower than that of the original form of collagen, enhancing its water absorption, solubility, and water retention properties. Hydrolyzed donkey collagen peptides possess bioactivities beneficial to bone tissue, including promoting bone-forming cells and improving calcium absorption. These characteristics make collagen peptides a novel revolutionary ingredient for dietary interventions aimed at promoting bone health.
Hydrolyzed donkey collagen peptide supplements help increase the levels of physiologically functional dipeptides in the blood, such as proline-hydroxyproline (referred to as "PO") and hydroxyproline-glycine (referred to as "OG"). In vitro experiments have shown that PO can regulate the differentiation of chondrocytes into a mineralized form and promote the synthesis of glycosaminoglycans. Moreover, these bioactive dipeptides have been found to enhance the synthesis of hyaluronic acid (HA) within synovial cells, thereby increasing the fluid cushioning capacity between joints.
Product Features
Collagen hydrolyzed by Jiayi is more soluble in water and other liquids, making it easier to be absorbed by the intestines and skin; it also contains more antioxidants, which helps to slow down skin aging and improve muscle quality and strength.

Product Functions
- Improving sensory quality: In the food industry, hydrolyzed collagen can enhance the taste and appearance of products.
- Moisturizing properties: In the cosmetics industry, hydrolyzed collagen is used as a functional ingredient in creams and body lotions due to its moisturizing properties.
- Antioxidant: Hydrolyzed collagen is also used in the development of antioxidant supplements, often in combination with hyaluronic acid and vitamin C.
- Regulating cells: After hydrolyzed donkey collagen peptides are ingested, they are digested in the gastrointestinal tract and absorbed in the form of free amino acids as well as dipeptides and tripeptides, then delivered to target tissues via the bloodstream. Experiments have shown that collagen peptides can support osteoblast proliferation in a dose-dependent manner, which is the key first step in bone formation, leading to enhanced osteoblast differentiation and increased cell viability.
- Improving Joint Pain: Athletes are a high-risk group for bone and joint injuries. According to a comparative study in 2008, the incidence of acute knee sprains among athletes with new-onset knee discomfort was significantly higher than in non-athletes. The U.S. Food and Drug Administration (FDA) considers collagen peptides to be a nutritional supplement belonging to food, which can reduce joint pain in athletes, decrease dependence on analgesics, and enhance athletic performance. In recent years, clinical studies on the use of collagen peptides to reduce joint pain in athletes have also received considerable attention. For cartilage metabolism, adequate glycine and proline are essential for ensuring cartilage regeneration. Insufficient amino acid supply after high-intensity exercise can lead to cartilage damage. Hydrolyzed collagen is mainly composed of peptides with molecular weights between 300-20, 000 Da, as oligopeptides, they do not require digestion, are not easily broken down, and are fully absorbed by the small intestine, thereby entering the human circulatory system to exert their functions. In an experiment conducted in 1990, 60 male sports enthusiasts were divided into two groups, with the experimental group taking 10g of collagen orally every day. After several months, the amino acid content in the body was six times that of before, especially with significant increases in proline, glycine, and hydroxyproline; it was also confirmed that collagen substances have a synthetic and metabolic effect on cartilage tissue, stimulating chondrocytes to synthesize. Therefore, appropriately supplementing with high-quality hydrolyzed collagen peptides can play a protective role for joints. Studies have shown that daily intake of about 10 grams of hydrolyzed collagen can prevent and alleviate exercise-induced joint pain, and the molecular weight of products suitable for human absorption is about 3, 000 Daltons.
