Green tea extract

Latest comment: 1 month ago3 comments2 people in discussion

I believe the section on extracts is somewhat incomplete, as it focuses largely on polyphenols. I have suggested an edit, which has been reverted - so I would like to discuss it here:

- green tea extracts are marketed for a range of health benefits, whether they are substantiated or not is a different question, but I think it is important to state why they are marketed. - they do have adverse health effects, and as thus there is a warning by various agencies (including health Canada, EFSA)

I don't think the composition is really relevant for extracts, as it doesn't really differ from green tea, hence my suggestion:

Green tea extracts have been associated with a range of potential health benefits, although there is insufficient evidence supporting those claims. [1] Extracts are sold as dietary supplements in liquid, powder, capsule, and tablet forms,[2] and may contain up to 17.4% of their total weight in caffeine,[3] though decaffeinated versions are also available.[4] Excessive intake can result in liver damage (see Green_tea#Health effects).

Sorry, this does not seem to make sense? Is there some edit proposed here? Bon courage (talk) 17:22, 27 August 2026 (UTC)Reply

Sorry - yes, the text in italics.

My rationale: extracts don't differ in their composition from green tea, so repeating the composition does not provide any additional information. They are sold for a range of diseases (as described in the EFSA opinion), which might be useful to state.

The current statement ("[...] which collectively have no proven biological effects in humans.") contradicts the potential adverse effects of green tea extract. Ggck2 (talk) 17:38, 27 August 2026 (UTC)Reply
