Using Bromelain to Encourage Implantation – One Pineapple Slice at a Time

Using Bromelain to Encourage Implantation – One Pineapple Slice at a Time

A pineapple a day, keeps the doctor away… Wait. That’s actually an apple, isn’t it?

Never mind. Perhaps pineapples can’t ward off doctors, but they can produce a few benefits you still might be interested in.

Pineapple Core for ImplantationPineapples are loaded with an enzyme called bromelain; an enzyme that can produce some pretty incredible effects when ingested in the right amounts. In fact, bromelain has indications which include acting as a:

  • Pain Reliever
  • Blood Thinner and Anti-Coagulant
  • Anti-Inflammatory Agent

Basically, bromelain is nature’s aspirin. So, if you are suffering from a chronic pain condition, like endometriosis or arthritis, a pineapple a day might actually keep the doctor away yet.

And if you are a woman struggling to conceive, it might accomplish far more than just that.

You see, the benefits of blood thinners (in moderation, of course) during those months of “trying” is that they drive blood to the uterus, encouraging sticky embryos and reducing the chances of miscarriage. The fact that bromelain also functions as an anti-inflammatory means that it has promising benefits for your immune system, possibly preventing implantation issues which can be common for women who have inflammatory conditions.

“Conception and implantation require an intricate shift in the immune system, specifically a shift from TH1 immune cells to TH2. Basically, this means conception requires an anti-inflammatory shift. It is possible that bromelain helps with this shift which allows implantation to occur…” shares women’s-health specialist, Naturopathic Doctor Elise Schroeder.

Traditional Chinese Medicine has long touted the benefits of bromelain for fertility, and with science gaining a greater understanding of how the enzyme works – it becomes easy to understand why. There is a catch, however. Consuming too much bromelain at the wrong time in the cycle may be prohibitive to conception. Timing consumption of bromelain is important to support implantation.

The Right Way to Eat Pineapple for Implantation Support

It may sound like a fine line to walk, but a little bit of information can go a long way when it comes to understanding how to use pineapples in your favor. First, make a point of staying away from this tasty fruit in the weeks prior to ovulation. The acidity can actually backfire against fertility at that point, causing your cervical mucus to become inhospitable to traveling sperm. It is also suggested that you avoid ingesting bromelain once you have a positive pregnancy test. According to licensed acupuncturist Heather Pentland at the New Leaf Healing clinic, ingesting large amounts of bromelain may cause mild contractions and slight thinning of blood which may not be supportive for implantation in very early pregnancy.

That gives you an approximately 10-14-day window when eating pineapple could do you a world of good.

To achieve the best results, you should:

    1. Purchase a ripe pineapple. Organic is always best.
    2. Use a knife to remove the pineapples exterior.
    3. Cut through the middle of the pineapple, from top to bottom, leaving halves to work with.
    4. From each half, slice six to eight equally sized wedges.
    5. After confirmed ovulation (or an embryo transfer, in the case of In-Vitro Fertilization), begin consuming one to two slices of pineapple each day.

It is important to remember not to core the pineapple – you will want some core in each of your slices, as the core contains the highest concentration of bromelain. One to two slices are really the most you should ingest in a single day as well. And because of the blood thinning properties, you should also avoid taking aspirin (or any other medicinal blood thinners) while consuming pineapple on a daily basis.

You won’t be able to achieve the same results with canned pineapple, as the heating process for canning is actually destructive to bromelain. That means going out and finding a fresh, whole pineapple – sticking to organic whenever possible. The wedges can be stored in your refrigerator and one pineapple should last you until implantation has occurred. All you have to do is focus on enjoying your daily tropical fruit allotment, while envisioning a healthy embryo implanting safely into your uterus.

If you are lucky, that pineapple a day will have you seeing a whole lot more of your doctor in the months to come – for only the happiest of reasons, of course!

    After implantation dip do you stop eating pineapple?

    • Dear Cathleen,

      I’m not certain I know what you mean by “implantation dip”. If implantation happens there will not be a dip in BBT (basal body temperature). It is when implantation does not happen, that BBT will fall or “dip”. It is fine to eat the pineapple fruit all cycle long, but it’s believed that eating the core is best from just after ovulation until pregnancy is confirmed, or menstruation begins.

    I am planning on starting IVF early 2018 is it ok if I start a bromelain supplement now ?

    Thank you

    • Hello Ashley!

      Bromelain is something that can be used for several months in a row, so it should be fine. Do follow the suggested use of the manufacturer of the supplement you purchase.

      Have you seen our free IVF Checklist? You may appreciate having that!

      My very best!

    Although the Western nutritional science behind eating pineapple cores to help implantation may be strong, this is not a practice from Chinese medicine. (I’m a licensed acupuncturist, teacher and practitioner of Chinese medicine.) Pineapple appears in some Chinese dietetics texts, but not for this use. In fact it’s more common to recommend avoiding eating pineapple for women who fit a diagnosis of “dampness,” roughly correlating with obesity, tendency to develop cysts, etc.

    Does bromelain herbal supplements work just as well as fresh, organic pineapple? If so, what is the recommended dosage for the supplements?

    • Dear Ashley,

      A Bromelain supplement is just fine. It is best to follow the suggested use of the supplement manufacturer and consult them if it can be taken in pregnancy. Eating raw pineapple core is fine to do in pregnancy (and during the two week wait when implantation occurs we want you to be thinking pregnancy ;-)).

    Tomorrow at 2pm is my first embryo transfer. I purchased a beautiful organic pineapple this morning. Should I start eating it today or tomorrow? Thanks for the great article.

    • Dear Lala,

      I hope you are excited and feeling well! I should think eating the pineapple both days and after would be just fine!

      My best!

    The saying “It can’t hurt to try” in this case, is entirely true. You may call this coincidence if you’d like, but I believe the pineapple is what helped us conceive! To sum it up, my husband and I tried to conceive for four years (spending thousands on Dr. bills, medications, etc.). Well, I was on chlomid for quite a while (which can thin your uterus lining and an egg cannot implant if it is too thin) so I wanted to find a natural way to thicken my lining. That’s when I read about pineapple and fertility. Well, I ate the required amount and the month I did that, I became pregnant. I not have a beautiful 18 month old daughter:)

    Hi there,
    I have been having 1 slice of pineapple (including the core) now since 2 DPO, it is now 11 DPO and I’m just wondering if I’ve taken it too long?
    I know your post above says to stop with a positive pregnancy test, but there are other sites that say to only consume it 1-5 DPO due to the risk of miscarriage.
    Should I stop now? Or will the damage be done?
    Many thanks

    • Dear Emily,

      I have not ever heard of pineapple (including the core) causing harm or damage in pregnancy. If this worries you though, do stop. We don’t want you to worry about our diet, rather we want you to enjoy it!

    Can I get some clarification on your meaning when you say to begin the pineapple the day AFTER ovulation has occurred? I know that when you get a positive OPK ovulation is supposed to be occurring within a certain amount of time. I’ve heard 12-36 hours but I’ve also heard 1-3 days. So do we start the day after the positive OPK or the the day after we think ovulation should have occurred 12-36 hours later? What about if you are using a trigger shot? My dr is having me use a trigger shot this coming cycle and I was told I would take the shot and come in to have my insemination 36 hours later. Do I start pineapple the day of insemination then?

    • Hi Nickelle,

      You would begin eating the pineapple core the day after ovulation, not after a positive OPK. Ovulation typically occurs 24-48 hours after a positive OPK. BBT charting may help you to pinpoint ovulation as well. I don’t think it will hurt to begin it a little early, if you are unsure of when you are going to ovulate. In the case of IUI, you would begin the day of insemination.

    I have to take daily Enoxaparin shots (blood thinner) starting a week before my FET and through out pregnancy. If i’m already taking this blood thinner should I maybe not eat Pineapple? Too much blood thinners?


    • Dear Pam,

      I have not heard of pineapple eaten in moderation affecting the actions of blood thinning medications, but please do ask your doctor his/her thoughts on this. I am not familiar with the cautions of the medication you will take.

      Best wishes!

    I know I ovulate, I have tracked it before, but this month the OPKs don’t seem to be showing a surge! If I know from previous cycles when I ovulate, should I just go off that? I am just thinking I won’t get a positive test this month around and I don’t want to wait to take the pineapple.

    Hi – Few questions about pineapple/bromelain. I’m getting a frozen embryo transfer (i had one last month that failed)

    1. I start the pineapple slice(s) with core started the day of my transfer and 4 days after that so 5 days total?
    2. One the day of the transfer, does it matter if you consume the pineapple/bromelain supplements before the procedure or after?
    3. Is it better to use fresh pineapple or consume bromelain supplements?
    4. For bromelain supplements, do you suggest a dosage (80 mg, 100 mg, etc) and strength (1X day, 2x day).
    5. Should the bromelain supplement regimen consumption follow pineapple (i.e. start day of transfer plus 5 days)?
    6. Supplement grand recs?

    Thank You!


    • Dear Sheila,

      Pineapple fruit and core are fine to eat through the entire transfer and in pregnancy. Of course, everything in moderation, but one to two slices through the entire procedure should be fine. If interested in taking a bromelain supplement it would be best to be guided in doing so by your healthcare provider.

      All my best!

    I started taking chewable Bromelain a week prior to ovulation (80 mg a day). I noticed my ovulation pain was much less severe. Is it ok to take it prior to ovulation when TTC?

    • Dear Endy,

      It is great to hear you have experienced results! Bromelain has many benefits beyond supporting implantation. It can be taken all cycle long and Bromelain in the form of fresh pineapple core can be eaten through pregnancy. Be sure when taking Bromelain in supplement form that the maker endorses their supplement for use in pregnancy before taking it in pregnancy.

    Shall I start having the pineapple a day after ovulation or starting the same day of ovulation?

    • Dear Tooma,

      Pineapple, plus the core because it is the core that contains bromelain, can be consumed starting after ovulation is confirmed, after it has happened. It could be that same day or the day after.

    When you mean pineapple core, does it mean whole fresh pineapple?

    I am taking Wobenyzm N as also recommended by this site. Is there a risk in taking that supplement throughout my whole cycle sense there is Bromelain in it?

    • Dear Anna,

      Wobenzym N can be taken through the entire menstrual cycle even when trying to conceive. It is not to be taken during menstruation if you experience heavy menstrual blood loss and it is to be discontinued upon first determination of pregnancy unless being guided by your healthcare provider to continue in pregnancy.

    I take quercenase (quercetin 250 mg + bromelain 100mg) capsules daily for allergies. Do you think this could be affecting my fertility? I’ve been struggling to conceive…

    • Dear Amanda,

      I am sorry conception has been a struggle!

      I am not sure I can answer your question, as I know so little about you. This being said, the suggested use if Bromelain in the form of fresh pineapple core is just after ovulation, not for the two weeks prior to ovulation. It is then suggested to discontinue eating the pineapple core after confirming pregnancy.

    Thank you for the information. I had my transfer yesterday. Should I still try the one a day slice?

  19. Avatar

    Thanks Leah!

    I have tried this a couple of times, but do not have easy access to organic pineapples and it gets a little bit tricky especially with irregular cycles. Would you recommend using Wobenzym N after confirmed ovulation?

    • Dear Katia,

      Suggested use of Wobenzym N is as suggested on the bottle or by your healthcare practitioner, to be taken on an empty stomach 45 minutes to 1 hour prior to eating, or 1-2 hours after consuming a meal with at least 8oz of water. It is better to take your dosage spread out throughout the day rather than all at once. Wobenzym is best used for 1-3 months consistently, each day of the menstrual cycle even after ovulation, for most conditions.

      If you are interested in trying Bromelain more consistently, it is available in capsule form and is often sold at healthfood stores.

      I hope this is helpful!
