    I’m interested in your tea, but don’t like tea unless it’s with
    some kind of cream/sweetner.

    Is there a combo of both, or at least sweetner, that wouldn’t
    affect the effectiveness of the tea?

    Thank you.

  2. Candi Kreeger commented:

    I am interested in purchasing your tea. My only concern is caffeine. I Wu-Long Tea, by chance, caffeine free?

    • This is a question we hear often. Our Wu-Long tea is not caffeine free. It is however naturally low in caffeine, about 1/3 the amount that you would find in a cup of coffee and slightly less than that of black tea.

  3. Linda Mack commented:

    Is this tea dangerous for someone with congestive heart failure or high blood pressure?

    • Hi Linda. The tea is 100% natural oolong tea with absolutely no additives or preservatives. However, in the instance of any medical concern, we suggest that you ask your doctor before trying anything new.

  4. Helen commented:

    I have a condition called atrial fibrillation which causes me to be on a continual blood thinner. I presently am taking Warfarin which is the generic form of Coumadin. I have been told not to drink any green tea because it interferes with my medication. Also, I can’t eat a lot of green vegetables, etc., but the green tea seems to be the most damaging to my medication. Can you please tell me if your tea is a green tea?

    Thank you.

    • Hello Helen. Our tea is oolong tea, not green tea. Oolong tea falls somewhere in between black tea and green tea and is semi-fermented. If you are on blood thinning medication and have been told not to drink green tea, we would ask that you consult with your doctor before trying our tea.

  8. Boo Omrani commented:

    Hi! I would love to try your tea. Do you have direct distribution in Canada? Also, we are trying to conceive, is it contra-indicated during pregnancy or breastfeeding?

    • Hello!

      We do not have direct distribution, the Wu-long Products are currently available online only at, but we do ship internationally.
      You should know that our products are 100% pure, premium-grade oolong tea. There are no additives or fillers. This means that the tea is very safe. However, for any medical questions (including pregnancy), we would ask that you please consult with your doctor to discuss what is best for you.

  9. Rhonda commented:

    You keep referring to the teabags. Are there any differences in using the capsules versus the teabags? Is the effectiveness the same?

    • The Wu-Long Capsules are a concentrated version of the tea in capsule form. They are just as effective (if not slightly more) and great for those who want to get the benefits in a convenient way. We recommend taking two capsules per day, one in the morning with a full glass of water about 15 minutes before breakfast, and one in the afternoon about 15 minutes before lunch.

  10. Glenda commented:

    I just listened to the “Special Offer” which was all about the benefits and origins of the tea. I want to thank you for the audio. I am visually impaired and had that all just been there in print for me to read I most likely would have closed the page. Very easy to listen and extremely informative. I thought I would ask my question before taking advantage of the Special Offer at the end of the video.
    My tea box is different than what I see pictured, it is black with pink/white writing. It lists Vitamin K on it. I am a lifer on Warfarin (blood thinners) and have just stabilized for the first time in 28 years. Is there enough Vitamin K in this tea to be worried about? I was thinking of cutting it down to one cup a day. I was told to stay away from green tea, so was glad to hear that this wasn’t. I am asking you because I know I would be asked/told “depends on the amount in it”.
    Thank you for your time.

  11. I am interested in ordering your Wu-Long Tea, but I only see you advertise the pills and tea bags do the Wu-Long Tea come in loose leaf form?

    • Hi Ann! Our tea does not come in loose leaf form at this time. Stay posted – we’ve had it before and are thinking about bringing it back in the near future.

  12. What are the side-effects of the tea? The side-effects caused by other “diet”/”slimming” teas are awful.

    • Hi Beej! The tea is 100% Oolong Tea Leaves. The reason you may have side effects with other teas is because they have preservatives, fillers, chemicals, colors, and even added herbs that have a ‘laxative effect’. This is not the case with Wu-Long. What makes it Premium is the fact that there are NO ingredients other than tea! If you have a caffeine sensitivity, it does have about 1/3 the caffeine as a cup of coffee. Enjoy your tea!
