Green Tea Contains Vitamin C, Black Tea Does Not, Research By RateTea Concludes
RateTea has conducted original research summarizing the scientific literature on the topic of the vitamin C content of tea, and has concluded that green tea contains small amounts of vitamin C, whereas black tea contains none.

Up until now, there was no central page or resource on the internet where one could find accurate information on the topic of the vitamin C content of various teas. What little information on this topic was available in reputable sources was buried in scholarly journals and scientific books.
RateTea publishes a new resource on the vitamin C content of tea:
In response to the lack of adequately-sourced articles summarizing in everyday language what is known about the vitamin C content of different types of tea, RateTea has conducted its own original research by scouring the scientific literature analyzing the nutrient composition of brewed tea and loose-leaf tea, and has published a new resource on the topic of tea and vitamin C. The core findings of the research were as follows:
Green tea was found to contain small amounts of vitamin C, ranging from about 2% to 11% of the US recommended daily allowance (RDA). Among green tea varieties, gyokuro was found to have the highest vitamin C content.
Black tea was found to contain no vitamin C.
White tea has not been adequately studied in order to conclude anything with certainty about its vitamin C content; however, what is known about the biology and chemistry of vitamin C in other foods, and how it changes with processing, would suggest that white tea would initially have a greater vitamin C content than green tea, but that the vitamin would break down more quickly over time in white tea.
