HEALTH REPORT
Ask Before You Sip
Slimming teas are not neutral around blood pressure pills. Which one you take matters.
Health Report · 8 min
Quick answer
Ask your doctor first. Drugs.com reports green tea reduced lisinopril absorption by about two thirds and nadolol levels by roughly 85 percent in studies.

The question worth asking
If you take a blood pressure medication and you are looking at a daily slimming tea, the honest answer is that nobody on the internet can clear it for you. Not us, and not the maker. That decision belongs to the person holding your prescription list, and it is a short conversation, not a lecture.
Why can tea change a pill?
A tablet has to be absorbed before it can work. Drugs.com reports that green tea cut nadolol levels by about 85 percent in one study, and reduced how much lisinopril reached the bloodstream by roughly two thirds. The pill was the same. What changed was how much of it arrived.
“The pill was the same. What changed was how much of it arrived. That is why the question is not tea or no tea, but which herbs, how much, and alongside which prescription.”
The interaction is not exotic
Drugs.com lists 14 drugs known to interact with green tea, rated 1 major, 7 moderate and 6 minor, including lisinopril, nadolol, warfarin, digoxin and several statins. That is a documented list, not a rumor. It also carries a caveat worth repeating: the list is not complete.

It depends which herbs
Texas Health Resources notes that ginger may increase bleeding risk in some people, especially when used regularly or in large amounts with blood thinning medications, and may also affect blood sugar or blood pressure in some cases. So the useful question is never just tea or no tea. It is which herbs, and how much.
Questions to take to your doctor
Bring the actual label, not the brand name. Ask whether any listed herb interacts with your specific prescription, whether the amount you plan to drink daily matters, and what to watch for after you start. Texas Health Resources suggests asking your doctor or pharmacist whether the ingredients are safe with your medications.
What about All Day Slimming Tea?
All Day Slimming Tea is a third party product, and the maker describes it as inspired by a Nicoya Blue Zone recipe, suggested three times daily. BloomWell did not create it and makes no health claim about it. If you take a blood pressure medication, the ingredient list is what your doctor needs to see.

How much is a lot?
Amount is part of the answer. Drugs.com advises avoiding large daily amounts, more than about three to four cups, or any high dose green tea extract, unless your provider says it is okay. A concentrated extract and an occasional cup are not the same exposure, and they should not be discussed as if they were.
Never adjust the pill yourself
One rule holds no matter what you decide about tea. Drugs.com is explicit that you should never stop or change a prescription dose on your own because of green tea, and that changes in blood pressure, heart rate, bruising or bleeding after starting or stopping tea should be reported promptly. Tea is optional. The prescription is not.
A clearer way to decide
Nothing here says you cannot enjoy a daily cup. It says the decision has one more input than the ads suggest, and that input is your medication list. Ask first, bring the label, and you will be choosing with the full picture instead of hoping for the best.
