The present invention relates to a polypeptide for delaying telomere shortening and its application, and belongs to the field of biotechnology. The present invention provides a polypeptide for delaying telomere shortening, and the amino acid sequence of the polypeptide is shown in SEQ ID NO.1. Studies have shown that the polypeptide has high biological activity and can significantly slow down the cell aging process by delaying telomere shortening, increasing the expression level of telomerase reverse transcriptase, increasing the activity of telomerase, and inhibiting the expression level of β-galactosidase. In addition, the polypeptide is derived from the fermentation process of natural dairy products and has high safety and low risk of side effects. In addition, the polypeptide has a small molecular weight and is easily absorbed by the human body, which can improve the bioavailability of the drug. Therefore, the polypeptide has great application prospects in delaying telomere shortening, anti-aging, and the treatment of diseases related to telomere loss or dysfunction.
