Q: Can I take this my entire pregnancy?

A: No, because Fertili-Boost helps produce progesterone and eventually your placenta will have supportive progesterone levels around 12 weeks of pregnancy.

Q: Can I take this even if I’m not trying to get pregnant?

A: Yes! Fertili-Boost is an excellent tincture for women of child-bearing age to take due to the hormone supporting herbs that promote hormone balance.

Q: How fast or slow do I need to taper off if I get pregnant? Why do I have to taper off?

A: The tapering protocol is as follows:

  • 20 drops, weeks 4-6
  • 15 drops, weeks 7-8
  • 10 drops, weeks 9-10
  • 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?

    My second cycle taking this tincture and I just got a positive test after almost a year of trying! I knew I had some hormone issues to work on and had been taking a similar tincture from another brand for about 5-6 months but felt the need to try something new. I was having up to 4 days of spotting mid cycle before starting this, and this cycle the spotting was basically nonexistent.
    I 100% believe this tincture is what allowed me to conceive this cycle.

    I’m currently still breastfeeding my toddler, and it’s hard to tell whether taking this lowered my milk supply. I night weaned right around the same time I began taking it, so my supply has changed a bit anyway. Since my son is almost 2, I’m totally okay with a drop in supply, and I’m still making plenty for the time being.

    Beyond thankful to have found this tincture!!

    Be cautious, this completely suppressed my ovulation!! Now we are out a whole month to try… people dealing with years of infertility know how frustrating it is to lose a month. This is such a disappointment. I have no idea how there’s so many good reviews. Maybe this isn’t for me because i have perfectly normal cycles, but there should be a warning not to take it if that’s the case. So frustrating!

      Thank you for your honest review. We are sorry to hear that you did not like this product. It is possible that there are herbs in the tincture that you are sensitive to, or that it is helping to balance your hormones and causing some changes to occur. Everyone reacts differently to herbs.

    We had been trying for baby #4 for 6 months, the longest we had ever tried, without conceiving. I was having some spotting before and after my cycles and I knew that was abnormal. Honestly, I was skeptical of this even after reading so many positive reviews. But I thought it couldn’t hurt so I decided to take it. One month into taking it and I’m pregnant! Thank you Earthley! I strongly recommend this product.

    I had no issues conceiving my 1st baby 4 years ago (wasn’t even trying as I was on the pill when I got pregnant). Tried 13 months for baby #2 no luck. Took this day one of my cycle/period and not only did I feel great that cycle…my period was 3 days late and I got a positive! I’m still taking it tapering off my dose, currently 8 weeks 🙂 I shared this in my trying to conceive social media group and about 15 women have ordered and one just said she’s pregnant! 🙂

    I used this for the first time this winter. I’m 39 and have 11 children. I usually get pregnant with no issue but I had a few cycles and nothing was happening even though we hit my fertile week. I figured I was just getting older and fertility was declining. I used this for about two full months and then got pregnant with baby #12! Praise God. Also, the previous two pregnancies I had to take progesterone pills in the first trimester to sustain the pregnancy and this time this was enough. That’s a huge blessing because the progesterone pills made me feel horrible and this did not. I tapered according to the chart here and I’m currently 24 weeks with a healthy baby girl. I will absolutely be using this again in the future!

    My cycles had been irregular for over a year. I used this in conjunction with Lunamore and within one month I was having normal cycles again.

    I bought this product and showed it to my nutritionalist. She recommended it and said that the ingredients in the Fertili-Boost are the same in a high quality prenatal supplement. I will keep buying this product to keep on hand.

  8. Jeiran Hasan

    This product should be a staple for any woman trying to conceive and it really works. I have not had any challenges conceiving but I know this product sped up the process. I took it for a few months before as part of my prenatal routine, and immediately got pregnant our first try. I feel so much stronger and held their this pregnancy after I’ve been taking these drops. The taste is not great but with any other liquid or in pair with other drops from Earthley, it’s totally manageable. Even now pregnant, I’ve had no issues with its taste or smell affecting me. 100% recommend this product. It’s still part of my daily routine.

  9. Alie (verified owner)

    I took this for about a month before we started trying. We tried the first month and I think that I must have gotten my ovulatory patterns wrong, but once I tracked my ovulation, I got pregnant right away. I believe that this stuff us potent and works as long as you get your timing right!

  10. Summer (verified owner)

    Okay I was skeptical…but desperate after trying to get pregnant for a year. I received the drops a week before ovulation and started taking them right away and got pregnant that month. I don’t know if it was just coincidence but it worked. However I will warn, it is the worst taste. So bad that I was convinced I wasn’t supposed to be putting it in my mouth but I couldn’t find any other directions. So good luck and have a cookie on hand.

    This stuff works. Fertility issues have been a thing with my siblings, so I purchased this before we started trying. I have been diagnosed with Grade II Endo and PCOS and MTHFR gene mutation. I started taking this about 3 months before we planned to try sporadically and then more routine the few weeks leading up to my fertile period. We are pregnant in the first cycle!

    Tried to conceive our second child for for 8 months, had an early miscarriage the second month. Took this starting during my period the beginning of our 9th cycle & got pregnant that month! Continuing it through my pregnancy right now. Thank you Earthley!

  13. Jessica (verified owner)

    I was trying to conceive for about 13 months with no luck. I am in my young 20s with no negative health history so it shouldn’t have been so hard, but it was. I started taking this tincture on the first day of my period and I got a positive pregnancy test a month later. This stuff really does work, especially if you suspect your hormones might be slightly out of whack. strongly recommend this product.

  14. Leora Keener

    All of my sisters take this! Wonderful product. Now I must buy!

  15. Amber (verified owner)

    I love this product! I can say it’s helped so much getting my hormones back on track and also helping my periods. They are so much less painful than they use to be and recently after getting my hormones checked and everything seems fairly well balanced, I’ve been sold on this. I definitely have recommended this product to several friends! Thank you!!

  16. Lindsay Miller

    It works! Within a couple of months of use, I got pregnant! I had been trying for 13 years!

  17. Hannah (verified owner)

    I swear by this now! We tried for a baby for several months and the first month that I decided to start taking this, I became pregnant! Thank you Earthley!
