Ovasitol Frequently Asked Questions

Ovasitol is a unique supplement for any woman with PCOS that combines myo- and d-chiro-inositol in the body’s naturally occurring ratio of 40 to 1.  This ideal ratio has been shown to reduce insulin, regulate periods, restore hormone balance, and improve egg quality and ovulation. Many women who take Ovasitol report a significant reduction in carbohydrate cravings. Here are the answers to the most common questions about Ovasitol for PCOS.

Can I take Ovasitol with Metformin?  Does this replace Metformin or do I take it with?

Please ask your doctor or other healthcare provider about taking Ovasitol with Metformin, or taking Ovasitol instead of Metformin.  Because both inositol and Metformin have been shown to affect insulin levels and restore ovulation, they may have additive effects.  In one study comparing myo-inositol to Metformin, myo-inositol showed slightly better results for restoring ovulation and increasing pregnancy rates. You can take Ovasitol and Metformin at the same time. This article about taking the two together may be helpful.

Can I take Ovasitol and other supplements?

Yes, Ovasitol is compatible with all the supplements sold in the PCOS Nutrition Center Store


Can I take Ovasitol if breastfeeding?

Yes, Ovasitol can be taken while breastfeeding your baby. We still recommend talking with your doctor first.


Can I take Ovasitol if pregnant?

Yes, Ovasitol can be taken throughout pregnancy. Taking inositol during pregnancy may be beneficial.  Studies have shown that myo-inositol supplementation during pregnancy significantly reduces the risk of gestational diabetes.


Is it available in Canada?


Ships FREE!

I live outside of the United States and Canada. How can I get this?

Sorry, We cannot ship outside of the U.S. and Canada.


How long does it take to receive my order?

Your initial order of Ovasitol should arrive within a week if shipped within the US. Orders to Canada may take 2-3 weeks. Theralogix, the makers of Ovasitol will send you tracking information once it ships.


Will this help me regulate my periods?

Yes, studies show that inositol helps regulate a woman’s menstrual cycle (period), and restore normal ovulation.


How should Ovasitol best be taken?

Ovasitol can be mixed into any hot or cold beverage with the exception of carbonated soft drinks and alcohol. It is best taken along with a meal in two divided doses.


Does Ovasitol have side effects?

Overall, Ovasitol is well tolerated. We recommend starting with one dose a day with a meal for the first week to minimize any risk for a side effect. Inositol, at the dose found in Ovasitol, is not expected to cause stomach upset.  However, if you do experience stomach upset, try taking Ovasitol with a meal.  For example, mix one packet of Ovasitol into liquid and drink with your breakfast, and mix one packet of Ovasitol into liquid and drink along with your dinner. It’s also great in a smoothie.



What does Ovasitol taste like?

Ovasitol is a tasteless powder. Since everyone is different and has different tastebuds, it could vary. Some say it tastes a little sweet.


Can Ovasitol help me lose weight?

According to the research, inositol may help with weight loss. Some studies have shown that women taking inositol have significant weight loss compared to women taking a placebo.  It is important to continue eating a healthful diet and being physically active while taking Ovasitol.


Is this something to take to help get pregnant or for PCOS in general?

Ovasitol can be taken by women who are trying to get pregnant and by those who are not trying.  Research shows that inositol helps to improve fertility chances by regulating menstruation (monthly period) and improving ovulation.  Inositol has also been shown to improve egg quality, which is important for women trying to get pregnant.

Why hasn’t my doctor heard of this?

Your doctor may or may not have heard about Ovasitol.  Ovasitol is a new inositol product combining myo- and d-chiro-inositol in the body’s naturally occurring ratio of 40 to 1.  This inositol combination has been shown to be more beneficial than either form of inositol alone.


What if I don’t have insulin resistance? Will Ovasitol help me?

Ovasitol has been shown to restore hormone balance and regulate periods. Many women who take it find it helps reduce cravings. Other uses of Ovasitol are to help with acne and mood.


I’m not trying to get pregnant. Can I still take Ovasitol?

For women who are not trying to get pregnant, or older women who are past menopause, inositol has also been shown to lower insulin, testosterone, triglyceride, and blood pressure levels, and increase HDL (“good”) cholesterol levels. Many women who take Ovasitol also see a reduction in cravings for carbohydrate foods and sweets.


Can I give Ovasitol to my teenage daughter?

Yes, Ovasitol has been shown to be safe in children as young as 8 years of age. For many, taking Ovasitol can regulate periods, reducing the need to take birth control medications.


What makes Ovasitol so much better than other forms of inositol?

Ovasitol is unique in that it combines myo- and d-chiro-inositol in the body’s naturally occurring ratio of 40 to 1.  This ideal ratio has been shown to work better than myo or d-chiro inositol alone. Too much d-chiro inositol has been shown to worsen egg quality. Ovaitol is pharmaceutical-grade and is the only inositol supplement to be independently tested by a non-profit third party to assure purity and accuracy.


Why do the Ovasitol packets cost more than the canister?

The extra cost is due to the materials for the packets and the process of packaging the individual packets. Many woman like the packets because they are easy to travel with or take on the go so you never miss a dose. Both contain a 3-month supply of Ovasitol.

    Every woman is different so I suggest you talk with your doctor if she/he wants you to continue. Ovasitol has been shown to lower the risk for gestational diabetes: http://www.pcosnutrition.com/inositols-decrease-gestational-diabetes-pcos-women/

    I posted a question on another post related to Ovasitol and I thought of another question.
    Is there a possibility this supplement can cause weight gain? You describe the mechanism and enhancing insulin sensitivity…that would increase the amount of glucose that can enter cells. As seen with insulin injections in those with DM, can this promote weight gain?

    Thank you

    Ovasitol is not associated with weight gain.

    Is Ovasitol recommended for women with high levels of DHEA-S? I got my bloodwork done and I don’t have high ovarian testosterone. My PCOS is stemming from my adrenals.

  • Angela Grassi

    Yes, it can reduce high levels of DHEA-S

    Hi, does Ovasitol have the same benefits for women who aren’t diagnosed with PCOS ?

    The research isn’t clear yet. There is emerging research that inositol, the component in Ovasitol can help those with diabetes:http://www.pcosnutrition.com/can-inositol-benefit-type-2-diabetes/

    I have only been taking Ovasitol for a week now but I forgot to take a dose before leaving for work this morning. Can I take a double dose in the evening to still get my 2 scoops/day?


  • Angela Grassi

    February 6, 2019 at 8:45 am

    Could you take it at lunch? Research shows it’s best to spread Ovasitol throughout the day instead of 2 at the same time.

    Husband and I have been ttc for over a year with no success. After I came off the pill in April of 2018 my periods became funky and irregular. I skipped several periods and my Dr would put me on Provera to get my period. I am now on my 3rd round of clomid on a higher dose (1000 mg). I didn’t ovulate last cycle and progesterone levels were low. Getting an ultrasound on day 12 of this cycle to check my follicles. Would Ovasitol help me at all???? I also have endometriosis. Thanks in advance for your answer!

    Yes, definitely! Ovasitol helps improve egg quality and restore hormone balance. The majority of women who take it see a regular menstrual cycle within 3 months.

    Hi! I’ve been taking this for about a month now and starting my first round of IVF and beginning my stimulation medication today. Should I continue to take this supplement through out my treatment? I know the timing of ovulation has to be precise from my doctor so not sure if I should continue

  • Angela Grassi

    July 29, 2019 at 10:47 am

    Hi! My daughter is 13 and recently diagnosed with PCOS with elevated insulin levels. May I ask how a child her age should be dosed with the product? We see an endocrinologist next week and I would much rather she try Ovasitol first before oral contraceptives or metformin. Thank you in advance for your guidance!

    Ovasitol has been used in children as young as 8, Yes, it is a great alternative to medication first!
