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 love this brand. I could not speak enough good words about it. Through the use of your fertili-boost and taking away the toxic chemicals in my life I got my first natural period since I was 14! Did something not even doctors could do for me!

  2. Kaitlyn (verified owner)

    I have a question about the tapering off do you keep taking it through the first trimester or taper off as soon as you figure out your pregnant??

    I started taking this herbal tincture to regulate my luteal phase completely before trying to conceive baby number four. My periods had been pretty good since 7/8 months postpartum except my luteal phase was 11 days instead of the ideal 12-14 days. As soon as I started taking this my next cycle was text book perfect. I had great regulated BBTs and my luteal phase was 13 days which was the first time I’d had a good luteal phase since birthing our third baby. I think it’s the vitex that did the trick but whatever it was I was thankful to know my body was balanced well.

    Only con is this tincture is very strong on the alcohol. Our family has literally cabinets full of all Types of herbal tinctures that we make or by from specific sources and earthly tinctures have undoubtedly been very potent on the alcohol taste.

    As a woman with Hashimotos, I knew that fertility was something I would need to support – especially balancing out my estrogen to progesterone ratio. I got pregnant my first month trying, receiving this product in the mail the day of ovulation and using it from that day to now (5 weeks along). I believe this helped with implantation and I’m so glad I am taking it. I also notice my mild cramping, which I’ve been having daily, reduces or disappears within an hour of taking my daily dose. I will continue taking this product until the end of my pregnancy to keep encouraging healthy progesterone levels. Thank you SO much, Eartley! Your products are literally unmatched. Grateful to you!

    When my husband and I got married, we wanted children just as soon as God would send them to us. A year later I still was not pregnant. We thought it couldn’t hurt to try this natural supplement as I did have a history of painful, irregular cycles, and if it could balance my hormones that would be great. A couple of months later, I was pregnant.
    God blessed us with a beautiful, healthy baby girl, and we believe He used the Fertili-Boost to help in bringing that to past.
    We thank God for the herbs he has given us, and the team at Earthley for preparing them in a way which is so easy to use.

    I got pregnant after 2 months of taking this. We had been trying for 18 months!

  7. Morgan

    My husband and I have had two miscarriages, and after my last one result in a D&C my hormones were off. My cycle was long, and I spotted for 5 days before my period. I knew we were going to start trying again soon so I tried FertiliBoost! Within the first month of use I no longer spotted before my period, and my cycle became shorter. The next month we decided to try again. I kid you not, we got pregnant in the first try! I was shocked. FertiliBoost was just what my body needed! I am 16 weeks pregnant now and so so happy! I cannot recommend this product enough!

    How much vitex is in this supplement?

  9. megan thurman (verified owner)

    This stuff helped me get pregnant after only a couple months on it!! Highly recommend. 4 stars instead of 5 because of the strong alcohol taste, but other than that it’s great!

  10. megan thurman (verified owner)

    I used this for a few short months and got pregnant pretty soon after! I gotta say this stuff probably had something to do with it haha. 4 stars instead of 5 because the alcohol can be pretty strong, but other than that, highly recommend if you’re trying to get pregnant!

    Hubby and I have been TTC for over two years now. I’ve had seven chem pregnancies and one mc at the 7 week mark. When we were first married my cycles were like 28 days and super consistent… they’ve definitely not been that after having so many losses that have messed up my hormones after my mc last May, my cycles have MAYBE been 25 days long if I’m lucky.
    I got this product about a week ago, and have been taking twice a day since (full dropper, maybe 20 drops?). And ladies. I’m currently on day 28 of my cycle, and I could seriously cry. I’m not pregnant, which I expected since I didn’t start taking till after ovulation, but the fact my cycle is this long is amazing to me. This has my stamp of approval and I’m literally telling everyone I know about it because I’m so happy!! ❤️
    I’m also doing nourish her naturally and the master tonic daily.
    Definitely excited to see what next month brings!!

    Pretty similar story, I have had irregular cycles ever since I stopped taking hormonal BC years ago. When we wanted to start trying, I made some other changes and started to get a more regular cycle but they were still a little unpredictable (also super long) and when tracking my LH with an OPK I never got a great spike (to predict ovulation) and was so confused. After our first cycle I felt so out of touch with my body and possibly had a chemical pregnancy but it’s so hard to tell, I just feel like my hormones needed some support and bought this product. It arrived right when my period ended in early June, had a very clear and high LH spike later in the month (right on schedule) which made me so happy!! 2 weeks later and I just got a positive pregnancy test!! I think this product definitely supported me in the way my body needed and I cannot recommend it enough!

    I started taking to help my hormones and I noticed a difference within a week!

  14. Lisa B

    If your trying to conceive this is definitely works amazing, I got my order June 1 st I believe only been using it 2 weeks and June 25th I got a positive pregnancy test I was soooo shocked , this product is definitely amazing thank you!

    I’ve been using Fertili Boost since March 2022 in hopes of balancing my hormones, etc. after having had some wonky cycles and a miscarriage in March. I found out a few weeks ago that my progesterone was on the low side and decided to up my dosage from 10 drops to 30. This week, I definitely noticed a change in my energy level and not feeling so fatigued. It’s too soon to tell if the fertili boost is helping with other areas, but I do feel like it must be boosting my progesterone as I’ve definitely noticed a change. Will keep taking!

    I have been taking this since the beginning of my last cycle. I had a non existent lethal phase and already this month it’s up to 9+ days. So thankful to see my progesterone rising. I am a nursing mom and haven’t seen side effects for my 1yo with taking this. We will be ttc this year and this is helping a lot to balance my hormones and regulate my cycle which just came back in the last month or two! I think this will be great in helping my body be the best it can for when we get ready to conceive. I will say it’s taste is horrible like alcohol. I take a half spoon of peanut butter and cover my mouth and then squirt it in my throat and swallow quickly. Does the trick! I also take cod liver oil daily and nourish her naturally.

    Bought this when we started trying to have a baby and got pregnant the month we started using it!

  18. Laura – Wise Cracked Mama (verified owner)

    Like others here, I started taking this to normalize my cycle lengths…and like others, baby appeared on radar within the month! 😉

  19. Laura – Wise Cracked Mama (verified owner)

    So, I started taking this to level out my uneven cycles post-baby 3 (Earthley didn’t have Lunamore when I tried this). It worked, all right! I didn’t even have a full month on this before…hello baby 4! 😉

  20. Robyn Taylor (verified owner)

    So, I noticed a couple of things when I started taking this in January. I had more energy and this might be TMI…but I was actually naturally well lubricated during intimacy. It was so drastic of a change my hubby noticed. Pleasant surprise! But…we’d be lazily trying to conceive since August 2021 after I quit taking birth control for 6 years. I started taking this January 5ish 2022 and had three positive pregnancy tests February 12th. I truly believe this supplement aided in that! 10/10 recommend.
