Peptides are naturally present in protein-rich foods. It is not necessary to take peptide supplements or use topical sources of peptides. However, some people may wish to use peptides with the aim of slowing down the aging process, or helping to build muscle and strength. Currently, there is still limited evidence to indicate that these products are effective, and much more research is necessary to assess their efficacy and safety thoroughly. Research into peptides is in the early stages, and in the future, scientists may discover health benefits of different types of peptides. Until then, people should exercise caution when taking any supplement and discuss the potential benefits and risks with a doctor beforehand. (责任编辑：) |
