Inositol Supplements & PCOS

PCOS can throw a woman’s hormones out of balance, affecting much more than just her ability to conceive.

Inositol powder can provide a genuine sense of hope for those battling conditions like PCOS, providing a gentle yet powerful way to bring back hormonal balance.  

A wealth of research and clinical trials have delved into how different types of Inositol can be a boon for those struggling with PCOS. Clinical evidence points out that a lot of women with PCOS struggle with insulin resistance. Myo-Inositol steps in to fine-tune the body’s insulin response, easing many of the symptoms tied to PCOS.

A systematic review of randomized controlled trials examining Inositol’s impact on patients with PCOS revealed its beneficial effects on hormonal balance, including insulin. Specifically, inositol was shown to:

  • Alleviate PCOS-related symptoms
  • Enhance glucose to insulin ratios
  • Lower the likelihood of insulin-associated health problems
  • Aid in weight reduction

Myo Inositol Supplements Australia FAQs

Research has not yet evaluated whether myo-inositol can balance hormones in healthy people without PCOS or fertility issues.

Myo-inositol—typically given at 2–4 g daily in combination with 200–400 μg folic acid—has been shown to improve ovarian parameters in women with polycystic ovary syndrome. In non‐PCOS women undergoing in vitro fertilization, one study reported that myo-inositol reduced gonadotropin requirements (2,084 ± 648 IU versus 2,479 ± 979 IU, p < 0.05) and modified luteinizing hormone levels (2.7 ± 1.1 vs. 1.6 ± 0.9, p < 0.01) while yielding fewer oocytes (5.9 ± 2.4 vs. 7.6 ± 3.8, p < 0.01) and producing no significant differences in pregnancy or implantation rates. No study has evaluated hormone balancing effects in healthy, non-infertile populations outside of the assisted reproduction setting. Mild gastrointestinal side effects have been noted at higher doses, although no substantial safety concerns were reported. (more…)

Inositol may be used as a natural alternative to fertility drugs in some cases, but it is important to speak with a specialist healthcare provider before using any supplement to improve fertility.
Inositol has been studied for its potential to improve sperm quality and motility in men, but more research is needed to confirm these findings.
Yes it is considered generally safe but it is always best to speak with your specialist healthcare provider before taking any supplement during pregnancy.
Inositol can generally be taken with other fertility supplements, but it is always best to speak with a healthcare provider before starting or stopping any new supplement regimen.

We recommend a dose of 4g per day taken as 2g in the morning with breakfast and 2g taken in the evening with dinner.

The recommended daily dose for women with PCOS is 4 grams per day. This can be taken as 1 x 4g dose in the morning. Or as 2g with breakfast in the morning and 2g in the evening with dinner.A 4 gram serve is a not quite flat metric teaspoon. A 2 gram serve is a not quite flat metric 1/2 teaspoon. We now provide a 2g scoop in our Natural Myo Inositol Product.

Inositol may improve fertility by regulating insulin sensitivity, which can help to regulate menstrual cycles and improve egg quality in women with PCOS.
Yes in some cases but not all. Fertility is a very complex matter and you need to consult a specialist health care professional.

What blood tests should I get for PCOS?

Refer to the Evidence Based Guidelines & our 12 essential PCOS blood tests post for more details on this.

✅ Anti-Müllerian Hormone (AMH)

✅ Total and Free Testosterone or Free Androgen Index (FAI)

✅ DHEAS (Dehydroepiandrosterone Sulfate)

✅ Sex Hormone-Binding Globulin (SHBG)

✅ Prolactin

✅ LH, FSH, and Estradiol (optional, not diagnostic)

✅ TSH (Thyroid-Stimulating Hormone)

✅ Free T4 (if thyroid dysfunction suspected)

✅ Oral Glucose Tolerance Test (OGTT)

✅ HbA1c

✅ Fasting insulin and glucose (for HOMA-IR)

✅ Lipid Profile (Total Cholesterol, LDL, HDL, Triglycerides)

Inositol is generally well-tolerated, but some people may experience side effects such as nausea, headache, and dizziness. If you experience any adverse effects while taking inositol, stop taking the supplement and speak with a healthcare provider. For mild side effects we recommend the ramping protocol of 1g/day in week 1, 2g/day in week 2, 3g/day in week 3 and then the full 4g/day in week 4.

It is recommended that you don’t take inositol with a lot of coffee as too much caffeine reduces the positive benefits. There isn’t a negative health effect rather just the reduction of positive effects.

How much is a lot? Depends on your body size and other factors but 3+ cups of coffee a day is a good place to start.

Why don't you sell a 40:1 D Chiro / Myo Inositol Blend. 1

The inositol problem in PCOS is that the body over converts Myo Inositol (MI) into D Chiro Inositol. (DCI) Adding more DCI isn’t the answer.

In PCOS patients with hyperinsulinemia, increased epimerase activity leads to excessive conversion of MI to DCI in the ovary, resulting in MI depletion and DCI overproduction (Nestler & Unfer, 2015; Unfer et al., 2014). 

This imbalance may impair FSH signaling and oocyte quality (Nestler & Unfer, 2015). Studies have shown that the MI:DCI ratio in follicular fluid drops from 100:1 in healthy women to 0.2:1 in PCOS patients (Unfer et al., 2014). 

The altered MI:DCI ratio may contribute to pathological steroidogenesis in PCOS, with DCI promoting androgen synthesis and reducing estradiol production (Unfer et al., 2020). 

Restoring the appropriate MI:DCI ratio has shown efficacy in PCOS treatment, and MI supplementation may improve oocyte and sperm quality in assisted reproduction (Facchinetti et al., 2016).

In addition D-Chiro has negative long term effects.

Inositol is a very safe food supplement. It is naturally found in mothers breast milk and often used in infant formulas and baby foods.

For a small percentage of women there is an adjustment process. This may mean headaches, dizziness, stomach ache or more frequent urination for the first few days or even weeks.

If this is the case for you, then we recommend you take your regular over the counter headache tablets and or start on a smaller dose and build up to the recommended dose slowly.

So rather than 4 grams per day you might take 1g in week 1, 2g in week 2, 3g in week 3, 4g in week 4.

It may also be helpful to split the daily dose into a morning and evening serving.

If problems persist stop taking inositol immediately and talk to your GP.

Inositol is recommended by some GP’s to women who are pregnant as it reduces the risk of gestational diabetes.

There are a number of peer reviewed studies where there has been no adverse effects from near conception through to delivery.

Always check with your GP if this is right for you.

We have not found a study to say that inositol in breastmilk causes problems for breastfeeding infants.

There are studies to support some positive benefits but there isn’t a lot of research on this.

We recommend that you make your own searches using the above provided sources.

If you do find something that we haven’t seen please let us know.

The planting area for corn in Australia averages 160,000 hectares and produces around 440,000 tonnes.

In China the area planted for corn is 76,000,000 acres producing 257 million tonnes.

This is well over 500 times more corn grown than in Australia.

Inositol production is a small fraction of this large quantity.

We haven’t found an Australian grown Inositol supply and suspect that the Australian industry is too small and serves other higher yield markets

Yes. It is GMO Free, Plant Based and Vegan safe. It is made from corn.

Depends on advice from your doctor. We cannot give medical advice and this is even more specialised as it is a toxicology question relating to your personal circumstances which we are not qualified to know.

Yes inositol is recognised as generally safe when used in recommended doses.

Compared to other products, the adverse events per 100,000 users is nearly 100 times lower than other common treatments like MF.

Inositol is a sweet carbohydrate powder food supplement used for treating PCOS, fertility, certain cognitive and insulin resistant health conditions. You are best to read the wiki page for a more technical explantion. Link here.

It reduces the hormone imbalances acting as a regulator of levels. It may help reduce hormone levels rising too high or falling too low.

Every women’s body and body chemistry is different. For some women Inositol works in days and for others not at all. The best approach is to test this out for yourself. If you don’t see benefits inside 60 days then this may not be a treatment for you.

We are most often asked just if our product is a 40:1 blend of Myo and D-Chiro inositols. The answer is no.

We only sell 100% pure Myo Inositol for four reasons.

1. The body converts Myo Inositol to D Chiro & other Inositols as it requires in a one way process. (Other inositols can’t convert to Myo Inositol). Myo Inositol is the primary building block for up to 8 different Inositols.

2. Myo-Inositol is more flexible treating both hormonal and reproductive symptoms alone than D-Chiro Inositol.

3. Too much D-Chiro inositol may be harmful in fertility applications. This risk is unacceptable to us.

4. The dose for D-Chiro is really small 0.1g per day. You are likely getting this from food already.

5. There are long term effects of too much D-Chiro inositol Please read: Nordio, M.; Bezerra Espinola, M.S.; Bilotta, G.; Capoccia, E.; Montanino Oliva, M. Long-Lasting Therapies with High Doses of D-chiro-inositol: The Downside. J.Clin. Med. 2023, 12, 390. https://doi.org/10.3390/jcm12010390 | R. GAMBIOLI, G. FORTE, C. ARAGONA, A. BEVILACQUA, M.
