  • 5 drops, weeks 11-12
  • Stop after week 12

Q: Does Fertili-Boost help promote healthy progesterone levels?

A: Yes, Fertili-Boost promotes healthy progesterone levels which is why it’s an excellent tincture to take to promote fertility!

Q: Why is there a caution warning for breastfeeding?

A: Vitex can cause decreased milk supply in some women, but it can also boost supply in others. If you take it while breastfeeding, make note of any changes in milk supply and stop taking it if you don’t want your supply to decrease.

Q: Why do I need to slowly taper off and not just quit at once?

    I have always had progesterone issues and have had fertility issues and miscarriages due to it in the past. When I started taking this tincture, we began trying to conceive 2 months later and conceived my very first cycle and my progesterone levels were at healthy levels during the pregnancy. I definitely feel that this product helps!

    This is an amazing product! Started taking postpartum when my cycle was irregular, had mood swings, wasn’t sleeping well, and had acne. After a few days I noticed a big change in my mood leveling out, better sleep, less acne and I ovulated that next cycle! A lot of times with natural products they are so gentle you don’t notice an immediate change but this was like night and day and I am so grateful!

    I have been taking this for about 2 months now. I was very consistent in the beginning and taking it 3 times a day. But now I usually only take it once a day. I just had my labs done again and everything has improved! So I feel this Fertili-Boost has helped. I take this along with Nourish Her Naturally. The both together have helped a lot! Hopefully now that we can get pregnant!

    I’ve suffered from back to back miscarriages which has led to irregular and intensely painful periods with lots of blood clots. It was so bad I was bed bound for days. I’ve been taking this along with Lunamore for the past 3 months and I feel like I have my life back. My periods are no longer painful and the blood clots are 80% gone. It also has helped with ovulation pain! I cried the first month after taking this I was so excited! As a side note, we have not tried for another child yet but the two combined have changed my ovulation and menstrual cycles so I have high hopes.

    Unfortunately I have not been able to try this product because when I opened it, I realized that the tip of the glass dropper was broken off. To be safe and not risk taking the chance of ingesting shards of glass, I contacted customer service and explained my situation and attached photos. The representative said that they could only provide me with a store credit (not including tax or shipping fees). I placed this order for Black Friday, so it was past their 30 day satisfaction guarantee. (I would have contacted them sooner, however I was taking another supplement that aided in fertility support, so I did not open the bottle until yesterday). I am very disappointed, to say the least. I love so many of Earthley’s products and order pretty regularly, but this situation has really left a bad taste in my mouth. I understand that they are a smaller business, but I definitely expected better.

    As many others have said, I had high hopes for this tincture. Personally speaking, it’s done absolutely nothing for me. I’ve been TTC for 2.5 years so I’m at the point of desperation and thought maybe adding this to my already very holistic regimen would be helpful, but I’ve not noticed even the slightest change in anything reproductive wise. The best thing I’ve done so far was an Ovasitol supplement, hands down the thing that has singlehandedly shown the most change for the better.

    I’ve been using this for a year give or take. Honestly I really had high hopes for this. Second bottle about done and I haven’t noticed any changes. Who knows why it’s not working, but it’s not. I’ll be taking a break from all things like this to focus on me and not conceiving for my mental health.

  8. Lydia B. (verified owner)

    I have been trying to achieve a pregnancy in my late 30s and found that my luteal phase had shortened to only seven days followed by nearly a week of spotting before each new cycle on a regular basis. I started taking Lunamore once daily and Fertili-Boost three times daily. I had high hopes that they would lengthen my luteal phase and help me to conceive. After four months taking these tinctures, my luteal phase has lengthened to 11 days and the premenstrual spotting is lighter and only a few days long. However, my cycles are still only about 25 days long and still no pregnancy. I’m also still having frequent menstrual migraines and mild menstrual cramps while taking these tinctures. I’m glad they’ve helped other women so much more! I hope I’ll find the right balance soon.

    I bought this for my 28 year old daughter, when I found out she and her husband had been trying for a baby for over 10 months. She begun using this mid November and had a positive pregnancy test within 7 weeks. Our granddaughter is just perfect! It’s definitely worth trying!

    Will be taking this again after baby #2 is born! I started taking this tincture before traying to conceive this baby and while obviously it helped with that, an added bonus I was not expecting was that I had the most painless periods I have had in my entire life, I didn’t even need to take any of the Ease the Ache. I had suffered with excruciating cramps since I first started my cycle around 13 and I am so happy to have finally found what my body needs to function as it should.

  11. Abigail Blumhardt (verified owner)

    My period stretched from 25 to 28 days within 2 weeks of taking this. After 4 weeks on this, we got pregnant after months of trying for our second. I’d say it ABSOLUTELY works!!!

    My sister introduced me to Earthley, first their sinus relief, then their cold tincture. I’ve loved them from the start, so it felt only natural to try the fertili-boost when my husband and I decided to try for a baby. We tried unsuccessfully for 2 months (not much, I know), but I also have PCOS and Endometriosis diagnoses. I started using the tincture just before ovulation in the beginning of October. I am now one full month in and my LH levels were the highest they have been, my skin is clearing up, and I am showing increased signs of fertility! What really made me a believer was when I realized that my period had been stretched one additional day (26 days to 27 days), which was something I had been aiming for, and I didn’t have Pre-period spotting/cramps/etc. This is truly a game changer! For those who don’t enjoy the taste, I simply put the drops in a splash of flavored sparkling water or some juice and I can’t tell the difference!

    My hormones have been all over the place since my last pregnancy 5 years ago. I was 47yr & through postpartum & beyond I hadn’t had a regular period since. After taking Fertili-Boost less then a month I finally had a normal period. That was 3 months ago. Before I was having menstrual symptoms without bleeding. It was super frustrating & stressful. It’s been such a relief to resume a normal cycle. Of course I’ll probably be entering menopause soon but until then I’m thankful this product has normalized my periods again .

    So far so good! I am in the throws of IVF, so I cant attest to this working for pregnancy, but so far I’ve had lessened cramping using this.

    My husband and I had been trying for a second baby for over two years. I did one round of fertility medication with my OBGYN that is supposed to release more eggs in my cycle in July 2023. I wasn’t pregnant so I ordered Fertili-Boost. I started taking it right away when I received it in August. My doctor update my next dose of medicine for my September cycle and I had been taking Fertili-Boost religiously. October 4, 2023 we finally received a positive pregnancy. I can definitely say this helped me get the sibling for my son that he’s been asking for. I am forever grateful for this company!

  16. Vanessa (verified owner)

    I was excited to try this considering all of the positive reviews of women who had gotten pregnant after taking this, but for me it messed with my hormones the month I started taking it. From ovulation up until period I had no rest from symptoms. Night sweats, fatigue, tender breast. I confused them for pregnancy symptoms until I realized this alters your progesterone levels. The reason I know this product is what caused it is because I’ve never experienced some of the symptoms like night sweats or to the severity that I experienced them until I stared taking this. Use with caution!

  17. Sarah (verified owner)

    This did not balance my hormones or help my fertility problems. I’m afraid my hormones are just too out of wack. It’s not the tincture’s issue, but it didn’t work for me. I had to be on Metformin for one cycle before getting pregnant! It’s not my preference to be on medication but it was what my eggs needed!

    I usually don’t write reviews but I just had to for this one. My lutheal phase was dreadful every month and for the first time since I had my daughter back in 2019 the pain was very minimal. Mainly using this to try and conceive but pleasantly surprised how much more energy I have and overall better mood I have. The best part was definitely a smooth lutheal phase. I recommend Eartheleys products to everyone!!

    I have had 2 miscarriages (both around 8 weeks) before taking this product. After my last one in January, I started taking Fertili-Boost and on my second cycle, my period was more normal than it has been in years. My mood balanced out and I no longer experienced hot flashes and extreme hunger and thirst. The next month, I got pregnant and I’m now 12 weeks pregnant. I have not experienced any bleeding at all this pregnancy and my symptoms are mild. I hate the taste because of the alcohol, but it works wonderfully. I HIGHLY recommend this product!

    Take the breastfeeding warning seriously! I was really excited to try this and used it for about a week at the smallest dose. I thought that since my 14 month old only nurses a few times a day we wouldn’t notice any significant supply changes. About a week in, my milk almost completely dried up. Since I’m not ready to stop breastfeeding and I doubt there will be a time where I’m TTC while not breastfeeding, I doubt I’ll ever get to actually use this stuff. Can we get a formula that doesn’t affect milk supply???
