Hi, I started the green Tea with EGCG yesterday after a great discussion with the pharmacist from the Ofev site. I have been on Ofev for 2 years now. So-she was so thorough in her response. First-no drug interactions with Ofev, next-she had the article and the study and said it was important if I was going to do it to match the amount of EGCG in my tea capsules as was in the study. I had purchased 500mg caps that showed 98% green tea BUT only half the dose needed per cap so she said I needed 2 a day. On re-reading the printout it does not say the daily needed substance for this study but she knew it! She also said to be sure the drug was certified by the government to be as indicated on label as many vitamins and supplements were not. Mine was GMO certified. I will keep you posted on how things go. Thanks, Kay
