Hello, perimenopause! Between hormonal changes, PMS symptoms, and trying to get everything back into balance, I've been looking for ways to support my overall hormone health. That's what initially led me to try Theralogix Ovasitol. One of the things I love most about this product is how incredibly easy it is to incorporate into my daily routine. I simply mix it into my morning drink, and that's it! It dissolves easily, has absolutely no noticeable taste, and doesn't change the flavor of my drink. No unpleasant aftertaste or complicated routine, which makes staying consistent so much easier. I originally started using Ovasitol to support hormone balance and help manage PMS symptoms during perimenopause. Interestingly, my most recent bloodwork also showed a change in my insulin levels. I can't say for certain whether Ovasitol was responsible, but it's something I noticed while using the product and plan to continue monitoring. I also appreciate that it contains a 40:1 blend of myo-inositol and D-chiro-inositol and is independently NSF certified for quality and purity. When it comes to supplements, knowing what's going into my body is important to me. While the price is a little higher than some other supplements, I appreciate the generous number of servings and how convenient it is to use. Overall, I'm happy with my experience so far. Perimenopause certainly comes with its challenges, and I appreciate having something that fits effortlessly into my daily wellness routine. Easy to mix, completely tasteless, and no fuss!

2/6/23: I started taking ovasitol 2 days ago at the recommended dose of 4000mg daily. My PCOS symptoms have been getting worse recently and I wanted to give this a try since I’m doing everything the same as what worked in the past for PCOS that my doctor had prescribed with the exception of taking metformin (I moved and have to find a new provider who actually knows how to treat PCOS so I don’t have access to it right now and was hoping this would help in a similar fashion). I had a mild headache after my first dose but it subsided after a few hours. The next morning I woke up with a rash on my chest and neck. It wasn’t itchy, but I had a bunch of tiny red bumps that were uncomfortable to touch and gradually worsened throughout the day. I took the same dosage that second day because none of the research I had done mentioned a rash being a side effect but by the evening it had gotten worse and I ended up taking some Benadryl before bed because I was still trying to determine the cause of the rash. Adding ovasitol is the only change I can think of. It’s been about 20 hours since my last dose and the rash is clearing up (the attached photo is from about 12 hours after the last dose). After researching side effects even more I found some others also broke out with a rash. Some were able to lower the dosage and gradually build it up or just kept going on the normal dose and it eventually cleared up while for other people the rash continued to get worse until they stopped taking it. I’m really bummed that I had this reaction because it seems many people with PCOS have had really good responses to inositols. I’m still debating if I want to attempt to take a lower dose to see if it helps and risk the rash flaring up again once it finally subsides completely. Update 6/25/23: The rash took about a week to subside. And after a month or two I decided to give it another try but start with a very small dose and see if I can work my way up. I started taking 1/16 tsp once a day and gradually was able to work up to the full recommended dose without any more rash issues. I did notice mild to moderate headaches the days that I increased the dosage, but they subsided after a day or 2 until the dosage increased again. I’ve been taking the full dosage for a few months now without any rash and no more headaches. My periods which have been irregular for as long as I can remember regulated within a month so it definitely seems to be doing something positive. I’m ordering more. So if anyone has a bad reaction initially, try to start with a small dosage and gradually increase. Wish it stated this on the packaging. Update 8/13/25: I have been taking this for 2 years now without any further issues. It has made a huge difference helping me to regulate my period and has seemed to help with other PCOS related symptoms as well. It is completely tasteless and dissolves well in hot or cold drinks. I have recommended this to several friends dealing with similar issues and they have had good results as well. If you’re on the fence, it is worth a try.

Tl;dr: I've been on this kind of supplement for a while due to PCOS and switched brands due to how sketchy the other brand is. No issues/side effects/concerns yet, but I plan to update this if there are any. Only doing one scoop per day right now to assess how my body responds. I've been using a myo-inositol and d-chiro inositol blend for quite a while prior to getting this brand. I was originally using one sold by Micro Ingredients, but the shadiness was just too much for me to risk it just to save a few bucks (claiming it's lab tested but customer service is non-existent so you can't even get proof, lawsuits against the company, finding a stray textile strand in the product, etc.), so I decided to just get this one to try instead. I received it on 3 April and started using it a couple of days after, when the last of my other one ran out. My review is going to have comparisons. Reasons I take this: I have PCOS, which comes with all the fun things like: irregular periods, hirsutism, difficulty losing weight, carb cravings, acne, the fun stuff. This type of product has helped with that immensely, as the hirsutism was showing in spots on my breasts and on my jawline/face/neck. I've also got the fun bouts of acne along my jawline that just randomly sprout up and go away (as they do). Taste: I've noticed that this brand does not have an aftertaste to it. You can tell that something is different about the water (not quite bitter on the back of the tongue, just different, if that makes sense), but there's nothing that really makes it taste sweet, salty, bitter, nothing like that. The other brand, however, had a sweet aftertaste, which makes me think they were adding other things to it, but I don't know. Maybe different sourcing, but still suspicious. Dosing/serving size: On the previous brand, I was double-dosing to get the results I wanted (I was able to do one dose a day for the first few months, but then the hirsutism was flaring again, so I had to start doing two), but this one I'm only doing one scoop a day right now to assess how effective it is. If I wind up needing to increase doses, I'll update my review. I've been using this brand since ~5 April and it's now 19 April. Side effects: I haven't noticed any side effects yet. I do know that (at least with the previous brand) when I was taking two doses, I would get nauseous, so I started taking it around the time I'd eaten and that solved it. This one I've taken without food (a single dose) and been fine. If I have to start taking two doses and experience nausea, then I will update my review for that. Ingredients: No complaints about them so far, seems good. I haven't reached out to the company yet to see if they provide lab results, but if they do, I'll update the review for that and their customer service. Mood: Haven't noticed any changes yet. It's 19 April as of writing this review, and I don't know that my mood will improve, as it didn't on the previous one, either (that I recall). We'll see. Energy: No changes so far. Could be due to my lifestyle, but my energy levels haven't been great for a long time. We'll see. PCOS issues: now, with the previous supplement, I noticed it improved my issues, but didn't necessarily stop them (like the hirsutism, it didn't stop it, it just slowed it down). Ovulation was normal on that one (I didn't track it, I just went by the physical cues). We'll see if my cycle stays regular with this new one and how the hirsutism and other issues do. Cravings and acne I haven't seen a change in yet, but time will tell. I'm hoping I don't need to double-dose (this brand is expensive), but I guess I'll find out soon enough if I need to up it. I will also note that I've started an additional supplement called ALA (Alpha Lipoic Acid) with added biotin, so I'm not JUST taking this one anymore, so please keep that in mind as well (I started it on 17 April). ALA is supposed to help with weight, egg quality, lower triglyceride levels, and lower glucose and insulin levels (if you look into this one to go along with your ovasitol, the R-isomer type (natural) is more recommended than the S-isomer type (synthetic) due to its bioavailability. I messed up and got one that's 50/50 (I didn't research it before I bought it), so that's where I'm at now lol), so they're supposed to be a power team together. According to what I've found online (thank you, PCOS Nutritionist Alyssa), when you combine inositol and ALA, there's improvement in your cycles, reduced androgens (a hormone; the most common androgen is testosterone), anti-Mullerian hormones (AMH) (plays a role in fetal development), BMI and insulin levels. If I haven't said it enough already in this review: we'll see. That's the tagline.

I recently discovered that I’m insulin resistant and I have a very bad relationship with food, my food noise has taken over my life for years and years. I went on Ozempic a few years ago and due to the insulin in the pen the food noise completely disappeared and I lost 50 pounds. I stopped taking it a year ago and I gained 30 pounds. All I would think about was food and my next meal and sugar and junk food. I was never satisfied. And I knew something was wrong either due to my PCOS or I was missing a supplement and I was exhausted and frankly desperate. I have access to wegovy but i didn’t want to retake it. And I honestly took it to ChatGPT and I was just researching what the hell i can do to end this cycle, and it recommended this supplement. At first I was skeptical, i was like “what do you mean a powder will stop my food noise?” but I’m on day 3 now and I’ve already lost a pound. I eat when I’m hungry and I can go to bed not obsessing over snacks or what I’m going to eat for breakfast. It has quite literally changed my life, I also have anxiety and a mood disorder and I’ve noticed this has also helped my moods a little bit. I’m not sure if it’s due to the fact that I don’t think about food 24/7 anymore or if it balanced out my hormones, but if you struggle with the same things I do, I wouldn’t hesitate by purchasing this. My doctor knew I had PCOS and insulin resistant for many years and yet she never told me about the supplement. I literally have never felt better. I’ve also joined a gym and mentally and physically I feel amazing. It doesn’t have a taste. I just mix a scoop in the morning with water and then the same in the evening absolutely fantastic 10 stars. *UPDATE* Cleared my stubborn back acne! I’ve been to numerous dermatologist for nearly a decade and nothings ever worked, this helped 2 weeks in!

I was diagnosed with PCOS and was having a lot of issues with fertility. My doctor told me to take this and I have to say this worked really well for me. This Ovasitol really helped with sugar cravings and contributed to producing better egg quality to help get me pregnant. I noticed that after drinking this regularly, my sugar cravings decreased and I was able to manage weight a little better. My blood sugar levels were thankful for this as well. I even saw a decrease in acne as a result of having less sugar. I not The biggest change for me was that my cycles became more regular again while trying to conceive. I also have endometriosis and had previously been on birth control that skipped placebo pills, so it took time for my body to regulate, but the Ovasitol helped me with that transition. I can’t speak to sleep improvements or period pain relief, since I didn’t notice a big difference there personally. Taking this daily is super easy. You just mix it with water and there is barely a taste to it. The only annoying part is that the powder sometimes collects at the bottom, so always give your drink a good stir or shake to make sure you are drinking the entire thing. One thing I will say is that it is pretty bulky and does not store in cabinets easily. Overall, this was an effective part of my routine and I’m still taking it even now. I’m currently a mom to a healthy baby boy, and while everyone’s experience is different, I’m glad I tried it and stayed consistent.

Love the product which helps regulate cycle but the single use serving packets were not as convenient as anticipated. Sometimes the packages were hard to open by hand, so they were not easy to add to drinks on the go. I still needed to find scissors to open them. The product itself is excellent and dissolves very well into drinks, especially hot drinks like coffee or tea. There is no overbearing odor. It almost has a sweet smell, but nothing else. I highly recommend this product but would use the container with scoop over the individual packets.

I've been using Theralogix Ovasitol for several months, and I've had a very positive experience with it. One of the biggest benefits I've noticed is that it has helped regulate my menstrual cycles, making them much more consistent. It's easy to take, mixes well, and doesn't have a strong taste. I also appreciate the quality of the product and the convenient canister packaging. Overall, I'm very happy with the results and would highly recommend it

THROUGH HONEST REVIEW ! I hope this message is useful for anyone on a TTC journey. A little back story. I learned of potentially having PCOS of Feb 2025 when me and my partner moved forward through my new OB for our fertility journey. The premom app below shows how my cycles have been since March of 2025. The first container I took was Ovasitol I purchased that April 23 of 2025. What I was doing before hand was taking a hormonal balance tea that I do not have listed here because it’s from an herbalist name Krystal you can find on Instagram or Facebook. I believe her teas which I had the baby boom tea and progesterone risings tea is what made me fall pregnant right before moving forward with fertility treatment around the same date as the ovasitol I purchased. I only took it for 3 days then stopped when I found out I was pregnant. Well unfortunately that pregnancy did not last long for I wound up miscarrying labor day week of 2025. I was so depressed and sad to say the least. So once I was miscarrying I started taking the Ovasitol and I believed it helped regulate my cycle after miscarrying (you can see from March up until May in my premom app where my cycles picked up). Fast forward I fell pregnant AGAIN and found out late Aug. So I literally only had two cycles before falling pregnant again. Well this pregnancy ended in unfortunately another miscarriage end of Sept. I was sad but not as sad as my first one. I do believe the Ovasitol helped me to say the least! Oct 2 (as I was actively miscarrying) I purchased the Pregnositol. Since then I have not fell pregnant but I do believe it helped with regulating my cycles really well. (As you see where my cycles picked up on my premom app). I decided to try Myo-Folate recently I purchased that in March. Then you can see that my last cycle was 36 days and I was so hopeful Myo Folate got me pregnant only to have my cycle come. Now i’m currently 2 days shy of my cycle coming (today is the 18th of May suppose to come the 20th). I can agree with others this product definitely delayed my cycle and i’m hoping it’s not the case this time but we will see. I got this product specifically because of the folate so I won’t have synthetic folic acid but seems like it’s almost impossible to find just folate anywhere so I thought I hit a jackpot. Overall it hasn’t caused any drastic changes. I have lost weight but it’s also probably because I drink herbal teas that suppress my appetite along with myo inositol. I will update if I do fall pregnant this cycle. I stopped the other two a little while back. If I do not fall pregnant this cycle I think I will use the last two products as they seem to keep my cycles regular and I truly believed Ovasitol got me pregnant without trying (was letting my body heal).
