Should You Drink Green Tea Or Not? (Updated For 2018)

Glass of green teaDo You Drink Green Tea Or Want To?

You Might Be Surprised With What I Found Out. Especially If You Are Taking Any Medications. Including Any Over The Counter (OTC) Medications.

My Journey with Green Tea To Help With My Stress and Anxiety

I want to talk about my experience about drinking green tea as I think that my experience may also help you. As you may know, I suffer from stress and anxiety and have a heart condition. I discovered that drinking green tea has some health related benefits.

After drinking green tea for health benefits for two to three months, I stopped drinking green tea because I discovered that drinking green tea may make some of the medication I am taking less effective than they would otherwise be.

I have divided this article up into smaller sections to allow you to jump to any section of special interest. I do of course suggest that you read the whole article. But due to time considerations at your end, this will allow you to jump straight away to the sections of special interest to you. I consider the Important Caveats With Green Tea section of special interest as it highlights some medical points that you may not be aware off.

Run It By Your Health Professionals

Health Professional giving advise to a patientIn hindsight, I very strongly recommend that you run the idea of drinking green tea with your health professionals, especially if you are taking any medications or have any condition.

I thought that drinking green tea would help. Before starting to drink green tea, I did some research and as no red flags showed up, I decided to drink some green tea every day. I actually have not been to my doctor since I started drinking green tea to run it by him. This was in hindsight a potential mistake. I explain why below.

I was with my heart consultant but it never occurred to me to ask her. After all, it is a normal product available as a “normal shop item” in supermarkets. And I was drinking the green tea mainly for my stress and anxiety, not for my heart.

Blood pressureI was only drinking about a mug and a half of green tea for six days out of seven for about three to four months. But during my last visit to my heart consultant, the last thing she did was to check my blood pressure. It was higher than normal. We were both surprised. Both she and I could not understand why, as before she checked it, we talked about other things. One of them being the fact that I was getting in between three to five hours of walking exercise most weeks. So my blood pressure should have been normal or lower than what she recorded earlier.

At the time, I did not understand why my blood pressure was higher than expected. I explain why I now think that drinking green tea may have been the reason why later in this article. It is very possible that you will find this information very interesting and possibly very applicable to you or someone close to you.

I found out that drinking green tea when on some medications may not be a good idea. I discuss some of my findings in connection with this later on in this article. This is very important, as drinking green tea when taking some medications may make the medicine less effective than it would otherwise be, which may lead to other undesirable potential outcomes.

The bottom line, is that for me, because I am taking some of these medications, it is not a good idea for me to drink green tea. I explain more below.

If you drink green tea and take medications, I would recommend that you discuss this with your health professionals in order to be sure that it is a good idea for you.

Please learn from my mistakes.

Please do not make the same mistake I did. I did not run the idea of drinking green tea with my Health Professionals. I would advise that you run the idea by your health professionals.

My Hot Drink Habits

Hot caffeinate coffeeI used to drink about six to eight mugs of caffeinated coffee every work day and about three to five mugs of caffeinated coffee every non work day. Over the course of some time, I cut down a lot on my caffeinated coffee. I now take about one to two mugs of caffeinated coffee per week, instead of the previous thirty two mugs to fifty mugs of caffeinated coffee. I am pretty pleased about that. 🙂

I then used to drink one mug of caffeinated tea a day. I was also drinking a mug and a half of green tea every day except for Sundays. I used to drink the green tea from a large glass which is equal to a mug and a half. I measured that glass before writing this. I also measured a mug and a cup, and discovered that they both contain the same amount of liquid. I was not expecting that.

I now no longer drink green tea. I now drink one to two mugs of caffeinated tea daily. I now drink one to two mugs of caffeinated coffee a week.

This means that I have cut down a lot on my coffee intake and increased my tea consumption quite a bit, compared to the old value of five to ten mugs of caffeinated tea a year.

I read an article praising green tea which highlighted the potential health benefits of green tea. I thought why not give it a go and see how that works out. The next time I was in the supermarket, I purchased a small box of 40 green tea bags. The instructions indicated to just add boiling water and to let it brew for a few minutes. No need to add milk or sugar.

When I sipped the green tea for the first time, I found that its taste left something to be desired. 🙂

Anyway I gradually acquired a taste for green tea and used to drink it every day, except for Sundays. I got used to drinking some green tea most days.

Important Caveats With Green Tea

caution advised - please take careI learned that drinking green tea is not a good idea for me as my heart consultant has me on a low daily dose of aspirin. I learned that being on a low daily dose of aspirin and drinking green tea is not a good idea at all.

I also learned that another study showed that drinking green tea when taking one particular beta-blocker removed the benefits of taking the beta-blocker. It is not known if other beta-blockers behave in the same way and more information is really needed to come to a final decision.

So for the above reasons I no longer drink green tea. I was drinking green tea mainly for the associated health benefits, but if the green tea makes the medications I am taking less effective and possibly lead to complications, then not drinking green tea is the way for me. As well as that, with what I now know I would think I would get really stressed and anxious if I was to drink even a small amount of green tea. No way would that help my health and overall wellbeing.

So for me, because I am on a low daily dose of aspirin and on a daily beta-blocker, drinking green tea is not a good idea at all.

These are very important warnings in connection with drinking green tea.

Contraindications

Important! Contraindications of Green Tea

If you have been prescribed aspirin by your doctor DO NOT stop taking it without consultation. DO NOT drink green or white tea if you are taking aspirin regularly. Both tea and aspirin prevent the blood from clotting, and so combining the two can cause haemorrhaging. For the same reason, DO NOT drink these teas if you are taking Warfarin. Green and white tea interfere with the effect of Warfarin and can make it ineffective.

Blood Pressure Medication

Green Tea May Interfere With Blood Pressure Medication

For certain people, green tea actually may do more harm than good—by interfering with a type of blood pressure medication called a beta-blocker.

A Balanced Take

Plus and minusLike a lot of things in life, there is not always a very clear yes and no. Yes, drinking green tea has a number of potential health benefits. However for people taking some medications, drinking green tea may reduce the effectiveness of the medications.

The Healthline.com article mentioned below is a general type of article and is well worth a read. The very detailed study referred to below is more of a research paper, is quite long, and quite technical in places however as a lay person, I could understand the main concepts discussed in the study. It is well worth a read.

My Opinion

discoveryIn my opinion, it looks like although drinking green tea has many health benefits, there are potential issues if you are taking any medication. In my own case, I now know that drinking green tea when taking aspirin is not wise. I also now know that it may make my beta-blocker less effective that it would otherwise be. I want those medicines to work as effectively as possible for my continued wellbeing.

I no longer drink green tea. It is just as well that I had not been drinking green tea for too long, about three to four months. I also was not drinking too much of it, only about nine mugs a week. Better safe than sorry. This also explains why during my last visit to my heart consultant that she said that my blood pressure was high. This surprised her and me. I couldn’t understand why. Now I have a potential suspect which I am pretty sure is the real reason which is great to know.

Drinking green tea is supposed to have many health benefits, however you need to be sure that it does not conflict with any medication that you are taking now. For this reason and to be on the safe side, I recommend very strongly that you consult with your health professionals if you plan on drinking green tea.

In my opinion, it would be best to write down the complete list of medications you are taking (including over the counter medicines) so that no medicines get overlooked. It is important that all health professionals treating you know about all medicines you are taking (including over the counter medicines). One of the health professionals treating you may notice a potential problem with your list and therefore advice you accordingly.

Here’s The Next Step…

Now I want to turn it over to you:

Do you drink green tea and take medicines? If so, I would very strongly recommend that you consult with your health professional in order to be sure that drinking green tea is safe for you.

Do you drink green tea? If so, do you find that it helps you?

Do you drink green tea before bed time and find it helps your sleep?

Either way, let me know by leaving a comment below right now.

  1. Olonisakin Kehinde says:

    I often heard some health personels mention that green tea is beneficial.  But in the real sense,  I have not taken it consistently to have noticed the effects but some elderly folks had reported that they feel relieved of internal stress with green tea. 

    I think caffeinated tea or drinks may have a way to interfere with your body systems and may cause some disorder….  Just my opinion anyway.  But really,  green tea may be a way to avoid taking too much caffeine into the body system.

    1. David says:

      Hi Olonisakin,

      There is a lot of information out there suggesting that green tea is good for you. However there are also some serious caveats associated with this. Taking some medication and green tea daily may not always be recommended as taking both the medication and the green tea together may cause issues. I have updated my article to highlight this very important information.

      Talk with you soon Olonisakin,
      Peace,

    Over the last couple of years I’ve constantly heard about new benefits discovered with green tea drinking, but stress relief is a new one on me! (very interesting though!). 

    You did seem to be taking in a lot of caffeine throughout the day, I suppose merely cutting this out will reduce stress levels by itself. I’m wondering if maybe green tea contains some form of caffeine? Will that affect your stress eventually?

    1. David says:

      Hi Chris,

      Yes, according to some websites out there, green tea can help with stress and anxiety. You are right that green tea contains caffeine, however my understanding is that the caffeine in green tea is very low dose in comparison to the amount of caffeine in caffeinated coffee.

      I did some more research regarding the five cups of green tea a day thing and found out something every interesting. Taking both aspirin in small daily doses and green tea daily is not recommended. I updated my article to highlight this very important information. I will no longer be drinking green tea as my heart consultant has me on a small daily dose of aspirin.

      Talk with you soon Chris,
      Peace,
      David

    Hi David, 

    Interesting article, I used to drink lots and lots of green tea, as a way to aid with weight loss. I must admit I wasn’t aware of the potential health risks associated with green tea whilst taking other forms of medication. I don’t drink that much green tea any more as I’ve made a conscious effort to drink more regular water but do you have any thoughts or come across research regards to green tea and weight loss benefits?

    1. David says:

      Hi Nate,

      I came across the following study regarding green tea and weight loss benefits.

      A 12-week study was performed including two groups of men with similar body mass index and waist circumference: One group ingested tea containing 690 mg catechins while the second group received only 22 mg catechins. The average weight loss in group 1 was 2.4 kg, whereas in the second group it was only 1.3 kg. Low-density lipoprotein levels of group 1 decreased by about 11.5%; in group 2, this was only by about 5.2%.
      Source: The very detailed study I mentioned in my article above.
      Hint: When you get to the actual detailed study, do a “find on page” function and look for ‘weight loss’.

      Talk with you soon Nate,
      Peace,
      David

    Wow I drink green tea on occasion but not that often anymore.  I was using it mainly for its metabolism boosting effects for losing weight. I was on propranolol for my blood pressure but have recently gotten off of it because my elevated blood pressure was mainly due to my drinking problem (alcohol) which I have cut off. I will definitely have to consult with my doctor next time I am on any medications before drinking too much green tea. Thanks for this eye opening article.

    1. David says:

      Hi Huy,

      I have to say that I was surprised to learn that there is a possibly that at least some beta-blockers do not function as well as they are supposed to if a person is also drinking green tea.

      I would advise consulting with your doctor about drinking green tea (even small amounts) when on any medications, including over the counter ones.

      Talk with you soon Huy,
      Peace,
      David

    Wow, that is quite the achievement to cut back on coffee like that! I’ve been struggling to get away from coffee for quite a while now. I’ve noticed that I get stressed and agitated when I drink too much coffee, but I still need the caffeine to get my brain to wake up lol. 

    Maybe I should consider doing what you’re doing. Drink green tea and only coffee on special occasion. What kinds of green tea do you drink? I know there are many flavoured ones and some of them are just very bitter.

    1. David says:

      Hi Petra,

      Thanks. I must say I was very impressed with I cut down on my coffee intake. I gradually cut down on the amount in small increments and increased my water intake by the same amounts until I got it down to about one mug of coffee a week.

      At this stage, after drinking green tea for health benefits for two to three months, I stopped drinking green tea because I discovered that drinking green tea may make some of the medication I am taking less effective than they would otherwise be.

      I was drinking green tea that I purchased in my local supermarket. They were normal green tea bags from a well known local brand. They were bitter and it took me a while to acquire the taste. I was drinking green tea for health benefits so I opted to put up with the bitter taste. Then I discovered that drinking green tea when taking some medications is not a good idea at all which as you know, I have discussed at some length in my article above.

      Talk with you soon Petra,
      Peace,
      David
