Does “green tea extract” contain caffeine?
I have looked at the supplement facts, ingredients for many brands of Green Tea Extract and none of them list caffeine. Green tea does although naturally contain caffeine, so I would guess that the extracts do as well, but I am just not sure.
1. Yes, but it is a very insignificant amount. By the way, be careful not to take those for a prolonged period of time though it is possible to develop a UTI. They can screw up your system, its better just to drink the tea if possible. Though taking them a month or two than stopping for a month or two should cause no problems.
