Tea pigments have significant effects on human health. However, more attention have been paid to their physiological functions. The aim of this study was to analyze the quantitative and qualitative impact of tea pigments on human health, together with their current and potential future research directions. The study searched and screened 520 publications on WOS from January 2002 to December 2022. The article collected and collated literature published in the last 20 years and analyzed it bibliometrically for years, journals, countries, authors, topics, keywords and strongest citation bursts. The findings of keywords and strongest citation bursts revealed that the most discussed research topics were anticancer, black tea polyphenol, antioxidant, activator inhibitor, in vivo, gut microbiota, and summarize the relevant literature. As a reference for future research, the literature pointed out current shortcomings and speculated future development trend of tea pigments.
