Caffeine & Fertility

Caffeine & Fertility

Does caffeine affect fertility or cause miscarriages? In this video I share with you the studies, the affects of caffeine on your fertility, miscarriages, hormonal imbalances, ovulation and more. It is more serious than you may have thought. I also talk about coffee alternatives that are good for you.

  1. Hi there,
    I’m on my day 4 of Liver cleanse. I cut down my coffee intake to drinking 1 cup coffee every alternate day. But since I’m still drinking coffee, will it affect the cleansing process? I drink Bru instant coffee which is half coffee half chicory.

  2. Hi Hethir,
    Thank you for this informative video. I am a caffeine addict and I had an ectopic couple months ago. Now I can’t help but wonder if my coffee habits had something to do with it because I did not have any other risk factors. Anyway, I started the Fertility Cleanse yesterday and I’m also weaning my coffee intake from drinking coffee everyday to drinking coffee once in 2 days. I wanted to know if decaf would be a good alternative. I also have chai tea imported from India. I’m currently on the liver cleanse phase, hoping it will detoxify all the extra hormones in my body from my eating habits.

    • Dear Anne,

      It is great that you have begun to make changes to support your overall and fertility health. Weaning off of coffee is great and from caffeinated to 1/2 caff. to decaf is one way to do that. Decaffeinated coffee still contains trace amounts of caffeine, but many decaffs not nearly as much as caffeinated coffee or even black tea. Make sure the decaffeinated coffee you choose is Swiss water process and/or organic is you can. The Swiss water decaffeination process does not use chemicals like most decaffeination processes do.

      Sending strength to you to help you through the process!

  3. I drink coffee but I like Pero.

  4. So chicory is not an issue …somewhere I read that it can create miscarriage….? Thank you!

    • Dear Maroa,

      I have not read substantial evidence that consuming chicory root prior to conception while trying to conceive will cause miscarriage. The Natural Medicines Comprehensive Database does however rate chicory as “unsafe” when consumed in large amounts during pregnancy because it might start menstruation and cause a miscarriage.

      In terms of using chicory root as a coffee substitute, this is not considered a large dose. It is commonly only suggested to consume a single cup of chicory “coffee” per day. One cup is made from only two to four grams of the root in about 2/3 cup of boiling water, steeped for 10 minutes and then strained off (the root itself not ingested).

      If you have concerns about miscarriage and questions about consuming chicory root, it really would be best to talk to your healthcare provider about it and certainly continue to do your research.

      All my best1

  5. Thanks so much for your explanation about the caffeine. I’m addicted to black coffee (2 double espressos) and I actively TTC. I have not been able to quit it yet. I cut it down to 1 cup per day. I’m strongly considering starting a coffee-free life especially if there are so many healthy alternatives like rooibos and other herbal teas.

    • Dear Yulia,

      Congratulations on being able to lower your intake to 1 cup of caffeinated coffee per day! If this 1 cup in still a double espresso, try making it with one caffeinated espresso shot and another decaffeinated (Swiss water process decaf is best) espresso shot to help you continue your “caffeine-elimination plan” of sorts.

      There are healthy alternatives, so start trying them to find several you like. Incorporating them into your daily routine will hopefully also help you continue to eliminate caffeine from your diet.

      Best wishes! I know it’s hard work!

  6. I drink Swiss Water Decaf. They say no chemicals. Is this true? Can I drink this?

    • Dear Amanda,

      To my understanding decaffeinated coffee made by the Swiss water process is chemical-free. For what it is worth, decaffeinated coffee is known to contain trace amounts of caffeine. I have read that United States regulations require coffee makers reduce the caffeine level of coffee by no less than 97.5% in order to label it “decaffeinated”. Decaf is a better choice than regular coffee, but not consuming caffeine at all may be best.

  7. You mentioned that estrogen is increased during the follicle phase, but estrogen is the dominate hormone during the follicular phase and is responsible for development of the endometrial lining. In fact it is the lack of estrogen in the follicular phase when taking clomid that causes the the uterine lining to be thin. Why is the increase level of estrogen during the follicular phase determental?

    • Dear Janice,

      Hormonal balance is a delicate balancing act. While estradiol is necessary during the follicular phase of the menstrual cycle and spikes prior to ovulation, too much estradiol during this time has been shown to impact ovulation. The study referred to is from the journal Fertiltiy & Sterility and showed that women who consume caffeine produce 70% more estradiol than normal during the follicular phase of the menstrual cycle. 70% more estradiol than normal during this time can over time lead to estrogen dominance.

  8. Hethir,

    I drink decaf instead of regular coffee will this be ok if you are trying to conceive?


    • Dear Gloria,

      While decaf coffee is better than regular caffeinated coffee, it still may contain some caffeine. The other downside of decaf coffee is that the process by which coffee is decaffeinated often involves chemicals. There can be chemical residue on the decaf coffee itself which then is consumed. If you must drink decaf coffee choose a Swiss-water process decaf. This process does not use chemicals, rather water.

  9. Thanks for the video, as well as all of the great information on this website. About three weeks ago I had a miscarriage, I was 12 weeks along. I am one of those 6-8 cups of coffee a day people….while pregnant I was able to get it down to 2 cups a day. So now, I suppose I won’t be drinking any of it–looks like it’s time to quit the caffeine altogether. Thanks for the suggestions.

  10. Hi , so can women drink coffee ? Pls advise .



    • Elizabeth Willett, MA, CH

      Dear Verly,

      A study conducted by Kaiser Permanente found a considerable link between caffeine and miscarriage. In looking at more than one thousand members, Kaiser found that women who consumed more than 200 milligrams of caffeine or more a day actually increased their risk of miscarriage.

      In addition to this, in pregnancy caffeine has been found to cross from the placenta to the fetus, and when it enters the body. The fetus and its underdeveloped metabolism are not able to break down the caffeine the way adults and older children can. In addition, caffeine might also play a role in improper cell development and a lack of blood flow to the placenta, both of which can increase the risk of miscarriage.

      Despite the potential for miscarriage, researchers and we of course understand that women who are pregnant need a way of managing fatigue that often comes with this journey and pregnancy. Researchers recommendation is to limit the intake of caffeine to no more than a cup or less a day, though they and we suggest that women who are trying to conceive and pregnant women should avoid caffeine altogether.

      I hope this is helpful!

  11. Oh man…green tea. I am addicted. I have poor ovarian reserve, though, and it looks like a slightly slow thyroid. If it wasn’t for green tea, I don’t know how I’d get things done. Looks like I don’t have a choice now, though!

    • Elizabeth Willett, MA, CH

      Dear Roxanne,

      Beyond the caffeine content of green tea, some scientific research suggests that green tea consumed in early pregnancy may inhibit the bodies ability to properly absorb folic acid. This being said, there are also many health benefits one can reap from green tea.

      The bottom line is that you need to do research to help you decide what it best for you and your fertility health.

      Here’s to being well informed!

  12. Yes addicted to tea.. I try decaf donated tea’s, herbal teas apple & cinnamon, lemon jest, ect but a lot of time I can’t stay away from proper tea but I’m trying once more

  13. Hi Hethir,
    Great information there to clarify why we should avoid caffeine! I am in love with a roast dandelion root and roast chicory root tea that we can get here in Australia. Amazing with almond milk and a bit of coconut oil. It is available in tea bags and in loose form which I put in my coffee infuser. Dandelion root is amazing for liver detoxification as well – very gentle, and as liver support is something that pregnant ladies probably need more than non-pregnant ladies this could be a good one as well. It has that rich flavour you were talking about.

  14. Update 2014 – We are back! We have been away for a while and we sure have missed all of your wonderful questions and thoughts on our articles. Moving forward, one of our staff herbalists will be here to respond to comments! We look forward to connecting with our readers once again!

  15. hi hethir i am trying to have a baby and i have been doing all that you said and i just made more orders to get more so i can get my baby.i don”t drink coffee but i do drink sodas and water,juices and teas too.i am trying to do all to boost my fertility.thank you hethir i wish i knew about this sooner.

  16. Hi Hethir, thanks for the video. The rooibos tea you talked about is very common here in South Africa and I’ve been drinking that instead of coffee for most of this year. I find even when I do go back to coffee I really don’t feel that well afterwards, similar to having chocolate to when you haven’t for a long time – so yes, it is hard at first, but afterwards it is actually preferable.

  17. Wow! I am so glad i found this website. I was searching for info on using Maca Powder yesterday but now i am “addicted” to this whole site. I knew coffee/caffine was not a good idea while TTC but i had no idea just how bad it was. Thank you so much for giving us all this information, backed up by scientific reasearch. Personally, i drink white tea (the yummy version of green tea!) maybe 2 cups a day. I was drinking 1 or 2 cups of coffee per week- but that is going to stop today!! Hot water and lemon for me. Thanks

  18. I have read that Holy Basil (Tulsi) has a negative impact on fertility, so I am surprised that you are recommending it.

    • Hi Cori,

      Thank you for pointing that out. I have read that as well, but through my research there has never been a real clear reason as to why Holy Basil (Tulsi) should not be used while trying to conceive or why it is bad for fertility. Most information just has this as a caution. Personally I think Tulsi tea in moderation would be fine, even while trying to conceive. Again, if you are consuming Tulsi everyday in large quantities, it may have an effect on your fertility. I think there needs to be some research into this area more.

      Holy Basil has been used for thousands of years as an adaptogen; aiding the body when introduced to stressors or hard physical demands. It has also been used as a remedy for reducing blood sugar levels in diabetics. Some research has shown that in men it may inhibit sperm production. Something to think about. We may have to do some more investigating on this herb.

      Thanks again,


  19. I haven’t had coffee for weeks. =) and today I put the coffee maker away :) yay! I want to have a baby so I am doing everything I can do to be healthy.
    I just drink one cup of green tea every other day.

  20. Great info, I am using a great product called Dandy Blend which has some of the same stuff as Cafix but with the added benefit of dandelion root that gives me the rich coffee-like taste. I also use Cafix but prefer Dandy Blend taste better. I will also take your suggestion on the Tulsi tea and try it.

  21. Hello,
    Thanks for the great info. I drink coffee every morning to make me feel more energize. I want to know is it okay if I change to decaf coffee?

    • Hi Lynn,

      It is up to you. Please read all of the comments to this video for answers on how coffee and tea are decaffeinated to see if decaf is a good choice for you.

      All the best,


  22. Thanks for all the information. What do you think about organic decaf?

    • Hi Julie,

      Organic decaf is up to you, I think it is still decaffeinated using chemical flushing. Ask the company you prefer their method of flushing.



  23. what about green tea?

  24. What about green tea? I thought that was good for fertility but, it does have some caffeine. I have about 1/4 tsp of Matcha powder per day. Is that too much?
    Thank you for the informative video!

  25. Hello,
    I drink milk with coffe every morning, but it´s 90% milk and 10% coffe.
    In my country we used to drink MATE, which is an herbal drink, that today I discover that also has caffeine. I´ll have to make another change.

  26. Thank you this information. I always find your information very helpful, however I am a gestational carrier and don’t use my own eggs when conceiving. I use your site for some tips on how I can help preparing my body for the embryo transfer I would be having & then also during those early months pf pregnancy. Basically we’re always on edge until the tests are done to confirm everything is fine with the baby. With regards to this video, I do like my daily cup of coffee however I do limit this when I am cycling for a transfer. There is so much to consider when thinking about your fertility. I myself have never had fertility when trying to conceive my own children. Being a surrogate was something I had always wanted to do for a very long time. This was due to knowing someone when I first conceived my daughter 13yrs ago. This broke my heart and I made a committment back then, someday I would try and help another women by carrying for her.

    So thanks again for the opportunity to send you this message and for all the good information you have on your website. I do refer people I am in touch with to your webite. Thanks for what you do !! I look forward to capturing future tips on preparing my body for the future little miracles being transferred in.

    Warm Regards,

  27. Thank You so much for that info!!! I drink about 1 cup of coffee every other day.I lost my baby at 19 weeks and when I was pregnant I was drinking coffee but not alot. I want to change my eating habits and eat clean its just so expensive. I wanted to know where can I purchase these products you were talking about?? also where can you get that cubuja-(sorry for the misspelling) the bubbly alternative, cause sometimes I need some bubbles after I eat. I go to the Whole Foods Market. Can I get these things there? Thanks

    • Hi Genevieve,

      You should be able to get most of these at Whole Foods or another health food store. Amazon and Vita Cost online are another option. I am sorry to hear of your loss, may you go on to have a healthy baby!


    • Hi Genevieve,

      It is Kombucha, and you can find it at Whole Foods and other markets. It is fermented and naturally bubbly- it is very good for you. I get a big boost of energy from it. I like the “gingerade” by GT Enlightenment. So good!!

  28. Loved this video! Lotta kids in the 80s were pretty much raised by soda. In college, I worked at a coffee cart making fresh coffee for professors, and this made it easy for me to taste test everything I made: expressos, lattes, you name it. So the addiction grew. I stopped the diet cokes 2 years ago and limited my caffeine to that one cup per day. I drank that 1 cup in my first pregnancy and now 6 years later, finally stopped a month ago. I turned to green tea lattes at Starbucks and got advice to start drinking decaf green tea lattes which I started today, my O day. I am really interested in the teas that you have Hethir. I love spicy chai tea!! And that Cafix seems like a great alternative!! Thanks again for this video– anything to increase fertility!!!

  29. Is drinking a decaffeinated black tea still a bad option for fertility?

    • Hi Michelle,

      Please read all the comments to this article and you will find my answer to your question! Look for the post to Christina!

      Have a great day,


  30. Hi,
    Thanks for the very informative video. I don’t drink very much coffee. Maybe twice a week. I do drink a cup or two of green tea during the week. Looks like I’ll have to change that habit. I looked into Cafix and other caffine alternatives and found unfortunately that they could contain gluten which I’m allergic to. I’ll stick to the Tulsi Teas instead.

  31. will my husband he drink coffee.every morining.and he drink soda and me what can we do .

    • Hi Aneesah,

      Start of slowly; day-by-day eliminate one more caffeinated beverage until you are down to one for a while. Then switch to sparkling juice or another healthy beverage. Be sure you are consuming 2 quarts of water minimum a day, this will help your body adjust to the change and flush sugars and caffeine while hydrating your body.

      Best Wishes,


  32. Wow. Interesting. I drink coffee ( 1x day) and have PCOS. I am pretty addicted to it, and have tried to quit often but only last about a week, and often go back to it as a quick fix. I usually feel awful after a cup of really strong coffee, 4-6 hours later, like a sugar crash.

    I am trying to switch to green tea, but always want that push in the morning with a cup of coffee…

    • Hi Lisa,

      I urge you try something else like the tecchino or Cafix. You could also choose a high protein snack or Fertility Smoothie with Fertility Superfoods instead balanced by some whole grain toast or cereal.

      Best Wishes,


  33. Hi Hethir…thanks for posting the caffeine video – very interesting. I’ve been off the caffeine for 3 months now – I only drink tea, not coffee, so I converted to decaf tea. The one I drink is supposed to be well-sourced, and I find it does the trick for me. I heard that there are 2 different caffeine removal processes – one synthetic (bad) and the other carbon dioxide (good). Do you know about this? I’ve also been drinking vanilla and camomile tea which is gorgeous, and really loved the liver cleanse tea while it lasted:)…best wishes..Christina

    • Hi Christina,

      The chemical process to decaffeinate uses 8-12 rounds of rinsing with solvents to remove the caffeine. This can also change the chemical structure of the coffee bean, altering it taste and nutritional value. Decaf coffee usually still contains about 1-5% caffeine. According to Wikipedia the following solvents are used to decaffeinate coffee beans: first the beans are steamed, then they are rinsed in one of the following; dichloromethane and ethyl acetate. YUK! There is also the Swiss Water Method, which is less toxic, but costly which is reflected in the price of the coffee at the market. The process for how they decaf the beans is not good for the environment. When there is environmental pollution it affects our fertility by creating long-term potential health risk to our health. Dichloromethane has been linked to cancer of the lungs, liver and pancreas. This chemical can cross the placenta and in lab animals has shown fetotoxicity. Ethyl acetate is one of the main ingredients in glues and nail polish removers. It has low toxicity, but I am wary of eating anything that was prepared in chemicals at all! Now the coffee beans are repeatedly flushed in this stuff, and then rinsed repeatedly to get the solvents out, then they are dried. This process is said to show no traces of the chemical solvents in the end product, but hmmm that was a LOT of chemical extraction. All of this takes huge amounts of energy as well, which is also not good for the environment. This does impact the long-term health of our world for our children. This method is also used to decaffeinate tea as well.

      All the best,


  34. Hi, I used to love coffee and have 2-3 cups a day; but 1,5 year ago I quit.
    I have PCOS and I know that caffeine influences negatively on my condition. So, if I wanted to get pregnant, I had to change something…and the miracle comes…after one course of hormonal treatment and my strict diet, I am now 31 weeks pregnant and am waiting my baby girl in the mid of August. I am so happy!!
    Though, I still love coffee, but I replaced it with Teeccino (for a coffee machine) and Bambu (instant beverage from grains)… really nice hot beverages!! And the transition between the coffee and the replacement was very smooth, I never had the need of coffee again. The energy that coffee gives is imaginary, I feel pretty energetic for my condition :))

  35. i LOVE coffee,but i dont love the caffeen,i stopped drinking it a few weeks ago,but i do have one on Shabbos morning with cake or homemade cookies.i would like to find out were to buy that cafix and try that,i love your info videos keep up the good work!

  36. Hi, Very informative regarding caffeine. My husband & I have cut right back on caffeine. I’ve gone from 4 or 5 cups of tea a day down to 1. Is this ok if trying to fall pregnant (having 1 tea)?
    I read somewhere that if you jiggle your teabag in hot water for 10 seconds, discard that water, then re-pour your hot water using the same teabag, that this gets rid of the majority of the caffeine (as apparently most caffeine comes out in the first 10 seconds). How reliable is this? Have you heard of it? Thanks again

    • Hi Aly,

      Wow, how great you have cut your caffeine consumption by so much! Good for you. I am not sure that what you describe doing really gets rid of the caffeine that quickly because both tea and coffee are flushed in a chemical mixture of dichloromethane or ethyl acetate about 8 to 12 times to remove caffeine. Even one cup of black tea a day can affect your health, but you are doing so well that you have cut your consumption so much!

      Best Wishes,
