Product Description

Ovasitol Inositol Powder Supplement
Ovasitol Inositol

Ovasitol is the only 40:1 inositol supplement independently tested and certified for content accuracy, purity, and freedom from contaminants.

Scientifically Formulated.

Ovasitol contains a combination of myo-inositol and d-chiro-inositol in the body's natural ratio of 40 to 1. Research concludes that this ratio is more effective than other inositol ratios or either form of inositol alone.

PCOS Support.

Ovasitol is formulated to help support improved metabolic factors, normal menstrual cycles, and fertility in women with polycystic ovary syndrome (PCOS).

Optimal Dosing. Twice the Inositol.

Just two packets per day provide 4,000 mg myo-inositol and 100 mg of d-chiro-inositol, twice the daily dose of other brands.

IT WORKS!
5 out of 5 stars
IT WORKS!
I absolutely stand by this product! I have PCOS and I decided to order Ovasitol on a whim in Nov of 2021 as my husband and I were about to start trying to conceive (I was 36 at the time) and I started taking it mid November and 6 weeks later, two days before New Year’s Eve I had a positive pregnancy test! I now have a 7 month old son and feel extremely blessed. If you’re on the fence, try it! I have decided to start taking it again now for symptom relief. One positive thing I also did notice was that it took my anxiety away and my moods were great! 1000000% recommend!

    ABSOLUTELY! I can not stress enough how amazing this has been for my PCOS. It crazy how must doctors won't tell you about this but I can confidently say you'll see a change in your menstrual cycles. Even thought being consistent with it and taking it once and day here and there; it helped with my irregular periods as well as helped with some of the other side effect that come with PCOS.

    Reviewed in Canada on February 26, 2023

    My cycles are really messed up (ranging from 30 to 150+ days), but i technically don't have PCOS. I did all the tests in a fertility clinic (HSG, uterine ultrasound, blood tests) and it all came back good : im just a case of "unexplained infertility". We have been TTC for a year and a half (without testing with OPK). While waiting for appointment in the fertility clinic, I started tracking my BBT and my LH with both premom and Mira (which also test for e3g and PdG) and my chart was all over the place.
    I read about ovasitol and all the amazing yet unbelievable comments and decided to give it a try. I started using it on January 24th (then I was at CD 127) and after a week, I started to feel a lot of different things. 1st, my body tried to ovulate (I had an LH peak found on premom sticks, but it came down really fast and my BBT didn't peak). At that time, I had some ovulation symptoms. Then 5 days later, I had LH, e3g and BBT peak, and both premom and Mira confirmed ovulation. I also never had egg white CM and in that fertile window, I got it for 3 days.
    We BD every 2 days on the fertile window just to test the luck. I didn't get pregnant, BUT I got my period on February 25th (after a cycle of 158 days). Maybe it's just luck and I would have gotten my period even if I wasn't taking ovasitol, but I really think it helped me ! I will update next month to see if my cycles are normal, but if you're hesitating, go ahead and try it. I hope it will lead to a BFP soon, but just having my period is a blessing in my case !
    EDIT : After 3rd month of using Ovasitol, I got my BFP !! We never thought of being able to do this without help of fertility clinic, but I got my + on Easter. I can't 100% tell it's because of Ovasitol, but im sure it helped ! <3

    I can’t say enough about this product. I was diagnosed with pcos a few years ago and had been dealing with irregular severe cycles that would range from 16-40 days of heavy bleeding, really short luteal phases and sometimes no ovulation. I started the process a year ago to trying to get pregnant but even with 6 rounds of fertility meds, I couldn’t get pregnant and was sent to a fertility specialist.
    I started this supplement the beginning of April on cycle day 1 and I noticed an almost instant change in my period. 4 days with only 2 days of very heavy bleeding. I big change from the usual 16-40 days I was use to. I did have some spotting a week leading up to my next period the beginning of May but I noticed my luteal phase was 2 days longer then my usual 9-10 days. My period in May was my shortest one yet at only 2 days of heavy flow. During that cycle I tracked my LH and BBT to confirm ovulation. Ovulation was usually between CD19-25, this cycle it was on CD13. I did start spotting on CD11 which kept going until CD 23 but has since stopped. On a hunch I took a HPT and got my first positive at 12DPO. If it wasn’t for this supplement, I wouldn’t have gotten my BFP. I was suppose to start fertility treatments with the plan of doing IUI this summer and my follow up from all the tests is this week. But instead of planning for IUI, I get to tell my fertility specialist a miracle happened and that we no longer need to plan for IUI and start planning for baby.

    Update: ended up miscarrying at 9 weeks. If you are going to take this to get pregnant, please don’t stop taking it once you become pregnant especially if you have insulin resistance pcos. Stay on it for at least the first trimester.

    I was very excited when I ordered this product and it’s marketing makes you believe that’s it’s a one stop solution for all women with a history of pcos and those looking to improve fertility.
    However it does not mention that’s it’s not suitable for those who does not have insulin resistance. IT CAUSES WEIGHT GAIN! Do not take it without knowing what hormones are causing you trouble. If you are lean don’t take this at all. I wish the company had the integrity to put out the side effects for different people (there is lots of women who have had the same symptoms as mine) I stopped taking it within 10 days as I noticed the negative side effects. IT IS NOT A MAGIC PORTION AND IT DOES NOT SUIT EVERYONE. I wish 鶹 reads this and takes this product and gives me my money back.
