Hydrolysed bovine collagen, also known as collagen peptides, is a form of collagen broken down into smaller, easily digestible particles. It is derived from bovine sources, particularly skin, bone and muscle. It is commonly used as a dietary supplement to support healthy skin, bones and joints.
The name 'hydrolysed bovine collagen' describes the source and process used to obtain this product:
The production process of hydrolysed bovine collagen involves different steps:
It is worth noting that the quality of the final product may vary depending on factors such as the quality of the raw materials used, the specific hydrolysis process employed and the conditions under which the product is dried and ground.

This study found that collagen peptides induce the proliferation of fibroblasts and keratinocytes and the expression of pro-collagen-1α, factors beneficial to skin health. The study also found that collagen peptides reduce inflammation induced by lipopolysaccharide (LPS), a component of the cell walls of gram-negative bacteria. (1).
This study evaluated the potential of a thermophilic thermolysis-like protease (TLP), A69, in the preparation of bioactive collagen peptides from bovine bone. The study found that the prepared collagen peptides had good moisture-holding capacity and antioxidant activity, suggesting potential applications in the cosmetic, food and pharmaceutical industries.

Abstract. Collagen-based products are found in different pharmaceuticals, medicine, food, and cosmetics products for a wide variety of applications. However, its use to prevent or improve the health of skin is growing dizzyingly. Therefore, this study investigated whether collagen peptides could induce fibroblast and keratinocyte proliferation and activation beyond reducing an inflammatory response induced by lipopolysaccharide (LPS). Human skin fibroblasts (CCD-1072Sk) and human keratinocytes (hKT-nh-skp-KT0026) were seeded at a concentration of 5 × 104 cells/mL. LPS (10 ng/mL) and three doses of collagen peptides (2.5 mg/mL, 5 mg/mL, 10 mg/mL) were used. The readout parameters were cell proliferation; expression of inducible nitric oxide synthase (iNOS); expression of pro-collagen-1α by fibroblasts; and secretion of interleukin-1β (IL-1β), interleukin-6 (IL-6), interleukin-8 (IL-8), tumor necrosis factor α (TNF-α), transforming growth factor β (TGF-β), and vascular endothelial growth factor (VEGF) by both cell types. The results demonstrated that all doses of collagen supplementation induced increased proliferation of both human fibroblasts (p < 0.01) and human keratinocytes (p < 0.001), while only the dose of 10 mg/mL induced an increased expression of pro-collagen-1α by fibroblasts. Similarly, only the dose of 10 mg/mL reduced LPS-induced iNOS expression in fibroblasts (p < 0.05) and keratinocytes (p < 0.01). In addition, collagen supplementation reduced the LPS-induced IL-1β (p < 0.05), IL-6 (p < 0.001), IL-8 (p < 0.01), and TNF-α (p < 0.05), and increased the TGF-β and VEGF expression in fibroblasts. Furthermore, collagen supplementation reduced the LPS-induced IL-1β (p < 0.01), IL-6 (p < 0.01), IL-8 (p < 0.01), and TNF-α (p < 0.001), and increased the TGF-β (p < 0.05) and VEGF (p < 0.05) expression in keratinocytes. In conclusion, collagen peptides were found to induce fibroblast and keratinocyte proliferation and pro-collagen-1α expression, involving increased expression of TGF-β and VEGF, as well as the suppression of an inflammatory response induced by LPS.

Abstract. Bovine bone is rich in collagen and is a good material for collagen peptide preparation. Although thermolysin-like proteases (TLPs) have been applied in different fields, the potential of TLPs in preparing bioactive collagen peptides has rarely been evaluated. Here, we characterized a thermophilic TLP, A69, from a hydrothermal bacterium Anoxybacillus caldiproteolyticus 1A02591, and evaluated its potential in preparing bioactive collagen peptides. A69 showed the highest activity at 60 °C and pH 7.0. We optimized the conditions for bovine bone collagen hydrolysis and set up a process with high hydrolysis efficiency (99.4%) to prepare bovine bone collagen peptides, in which bovine bone collagen was hydrolyzed at 60 °C for 2 h with an enzyme–substrate ratio of 25 U/g. The hydrolysate contained 96.5% peptides that have a broad molecular weight distribution below 10000 Da. The hydrolysate showed good moisture-retention ability and a high hydroxyl radical (•OH) scavenging ratio of 73.2%, suggesting that the prepared collagen peptides have good antioxidative activity. Altogether, these results indicate that the thermophilic TLP A69 has promising potential in the preparation of bioactive collagen peptides, which may have potentials in cosmetics, food and pharmaceutical industries. This study lays a foundation for the high-valued utilization of bovine bone collagen.
