Green Tea and Thyroid Condition?

Is there any reason why thyroid conditions and drinking green tea don’t mix? If you’re on thyroid medication, is there something in green tea that will react badly, and do you know why?

    I am not sure where you are getting your information. As far as I know there are no compounds found in green tea that adversely affect thyroid function or the function of the hormones it produces. If you are having an adverse reaction to drinking green tea it is more likely a allergy that you have developed to something in the tea.

    Be cautious in using any herbal remedies. They are unregulated by the FDA and usually have no positive benefit despite their claims. Many of them claim to have clinical evidence. Unfortunately, there are many unscrupulous labs out there that will provide skewed evidence to prove just about anything their client wants. Until the government steps in and starts regulating herbals like the Germans and Europeans do this will continue to be a problem. There is a English translation of the German journal of herbal pharmacology available. consult your bookstores if you are interested in getting more accurate advice on the use of herbals than is available in the us.

    Any stimulant you take will eventually adversely affect your adrenal glands. So, be modest with green tea, coffee, etc.

    I recommend Bikram Yoga for stimulating the Thyroid without drugs. There are postures that really boost your metabolism, and also generate energy in most of your vital organs.

    Thyroid seems to be code for Metabolism or Weight Loss, if I am not mistaken.

    There is no known adverse effect of drinking tea while you’re on thyroid medication. But there are some herbs you should avoid mainly because it decreases the effect of the medication: agar, bugleweed carnitine, kelpware, soy & spirulina.

    I most certainly have not heard that green tea is bad for thyroid conditions.

    There are so many benefits to drinking green tea that it seems not possible. Check this collection of articles on green tea

    Article I found. Based on it, I assume fluoride can have a negative impact on your thyroid which green tea is high in.

    Is Green Tea Dangerous to the Thyroid

    by Mary J. Shomon

    March 2001 — In response to my article on green tea as a weight loss aid, some readers expressed concerns regarding the high fluoride content in tea, and the negative relationship between ingestion of too much fluoride and thyroid problems, as well as other health concerns.
    This is definitely something to be considered before deciding to take green tea.

  • Green tea contains fluoride and when you are hypothyroid, you should limit fluoride consumption

    It’s quite complicated. There are 3 parts to your question:

    1. Tea, and not just green tea, tends to interfere with medication. The rule of thumb is not to drink any tea beverages 2 hours after medications.

    2, If you suffer from hyperthyroidism, then green tea may not be good as it contains caffeine, which stimulates.

    3. If you suffer from hypothyroidism, then poor quality green tea may not help as it may contain fluoride.

    But high quality may help as the caffeine and catechins will give a energy boost.
