    • or I'd go months with no bleeding but terrible cramps. I've had multiple ruptured ovarian cysts
I suffer from PCOS. And I mean really, truly suffer. Since I was 12 years old I would have heavy bleeding for months at a time, or I'd go months with no bleeding but terrible cramps. I've had multiple ruptured ovarian cysts. It's been a nightmare. A few years ago I had a 10 month long heavy period, followed by 5 months with no period, followed by another 10 month long period and 6 months without a period. Finally I had enough. Up until this I have tried every natural route imaginable for my PCOS. Nothing was working and the thought of medication terrified me. At the age of 28 I was strongly considering a hysterectomy. Prior to this the most effective thing I found for bleeding and cramping was Red Raspberry Leaf, which worked great for easing heavy flow and managing cramps, however it did nothing to regulate my cycle. So I read about this on a forum, and immediately order this bottle off Amazon. By this point it had been about 6 months with no period, but 10 days after starting Inositol I had one. And not just a bleeding, but an actual period that lasted 8 days (that has never happened, I've never had one shorter than 2 weeks of heavy bleeding and terrible cramps in my life). Not only was my period only 8 days, it was light flow and very mild cramps. I started it May 1st 2014 and from then throughout the rest of the year I had 5 periods. All 7-8 days long, mild cramps with light flow. So it hasn't given me a perfect cycle, but that was the most regular I have ever been. It's always been heavy periods that last from weeks to months with terrible cramps, to months without anything. Basically no rhyme or reason at all. But with Inositol, things have gotten better. After mid December I ran out of it and with vacation, holiday stress, family illness and all I went nearly 2 months without taking it and back to a nonstop period. Today is 2/17/15 and I've bleed all but 9 days so far this year. I just started up taking Inositol again 2 days ago and already the bleeding is easing, no more cramps. So that's all the proof I need that this stuff works. Nothing is going to stop me from taking this regularly from here on out. I guess a part of me thought that maybe it was safe to stop, that things were good and it would be okay. That's not the case, apparently it is something I will have to continue to take but that is fine with me because it works! One more thing: For years I've dealt with ovary pain due to cysts. With this stuff, the pain went away. I had one cyst on my left ovary that throbbed for over a year and within a month of taking this there was no more pain. During my 2 months off from taking inositol the ovary pain came back (on my right ovary this time). So it's definitely been taking care of the cyst issue because it's a night and day difference between taking it and not taking it. In just the last few days since restarting it, the cyst pain has eased tremendously. As for dosage, I take a teaspoon in the morning and sometimes another at night. So 1-2 teaspoons per day. Aside from PCOS, I have noticed a slight improvement in my mood and anxiety when taking it. I definitely seem calmer. That was something I didn't notice the firs time around, but after slacking off from taking it I did notice a downward trend in my mood and anxiety. So here's hoping that will improve again! ... show more

    • A review for anxiety and panic relief seekers
Okay, so first things first, yes it works for anxiety, negative thoughts, panic and associated depression. That’s what I got it for, and experience almost instant relief from the more severe symptoms. 2nd thing, dosage will probably vary depending on the severity of your mental health conditions. My first time taking it I took roughly 6g and felt so lethargic I had to take a nap (for someone who normally can’t nap and has trouble sleeping this was a surprise and somewhat a relief). The fatigue wore off within an hour or so and the rest of the day I was anxiety-free. Second time taking I took about 2g and felt instant relief (within 10-15min) from anxiety and panic symptoms. I took a second dose of that 2g for continued relief a little later in the day. Anxiety sort of lingered on the edges but wasn’t full blown, which for me felt like a relief. Took another 4g in the evening and that was a mistake. Which leads me to my 3rd point, stomach issues. Yep it gives you diarrhea. Lots and lots of diarrhea. From what I’ve read, when your body gets used to it that side effect resides, and if you deal with stress and anxiety odds are you’re no stranger to diarrhea. I’d advise taking smaller doses at first and gradually getting your body used to it. I took a total of 8g my second time and had diarrhea and stomach issues for 24 hours. No fun. Side note: I’ve also given inositol to our five year old son in a very small dose (1/20 of a tablespoon) and his focus and mood have improved. He’s been going through a very moody phase and it seems to help. That small of dosage has not had the gastro side effects that I experienced. ... show more

    • Great quality, high potency, great price!
This is the most affordable, high potency, and high quality version of Inositol that I have been able to find thus far. If you need to take high doses of Inositol, you can't find it in a capsule in the US at this time (research has been done using a product that offers it in a more concentrated gelatinized form that is unavailable in the US). I recommend this product to my patients who suffer from a wide range of issues, including, PCOS, endocrine disruption (hypothyroid, etc.), miscarriages, hair loss, constipation, anxiety, OCD, etc. The challenge is that it takes at least a month if not two, of regular use to see a difference, but if you stick with it, you will see improvement of said issues. The dosage noted on the bottle is not enough to achieve full remission of all the above mentioned symptoms, but will definitely help with chronic constipation and PCOS (you may want to just take an oral capsule for lower doses). Consult with an integrative or functional medicine practitioner for more information on higher dosing, but generally, you need to progress VERY SLOWLY as you increase your dose to the required 4-6 tsp/day for anxiety, depression, and OCD. It can take over a month to achieve these higher levels as Inositol can cause diarrhea if you move to quickly! Many of my patients add it to a water bottle and sip from it throughout the day in order to avoid intestinal issues at the higher doses. You will need to work with your provider to see what works best for you. For those who need it, and have the patience to stick with it, this product can be a gift! ... show more

    • It's fine
I'm assuming it really is 100% inositol. Who knows these days. It dissolves immediately and has no flavor or texture. Super easy to use. Buyers should know about possible side effects of inositol.
