A review of the efficacy evaluation of oral bioactive collagen peptides

Abstract

Oral bioactive collagen peptide, as a functional food, has attracted wide attention in the fields of beauty, bone and joint health in recent years. Collagen peptides play an important role in the management of diseases such as osteoporosis and osteoarthritis by promoting skin collagen synthesis, improving hydration, and enhancing skin elasticity to fight against skin aging; and by stimulating osteoblast proliferation and inhibiting osteoclast activity to improve bone density. At the same time, collagen peptides demonstrate multiple health benefits by regulating intestinal barrier function, improving the immune system and cardiovascular health. Although a large number of studies have been conducted to support their efficacy, the mechanism of action of collagen peptides needs to be explored in depth, especially in terms of the molecular mechanisms and differences in the effects of different formulations. Future research should focus on understanding the mechanism of action of collagen peptides, exploring their synergistic effects with other functional ingredients, optimising formulation, improving bioavailability, and conducting long-term safety assessments. In addition, exploring its applications in emerging fields, such as metabolic diseases and cognitive function improvement, may provide new directions for its further development in the health industry.
