1PCOS symptoms improvementMeta-Analysisn=5,501 · very large study2025
In plain English: Chromium, inositol, and Omega-3 were found to be beneficial for improving lipid profile.
Zhao G et al. · Reproductive biology and endocrinology : RB&E (2025)
Inositol significantly decreased total cholesterol and triglyceride levels, while curcumin was most effective in improving low-density and high-density lipoprotein cholesterol levels.
Chromium, inositol, and Omega-3 were found to be beneficial for improving lipid profile.
For improving obesity, sex hormone levels, inflammatory factors and oxidative stress indicators of PCOS patients, carnitine, chromium, and soy isoflavones are effective options, respectively.
2Gestational diabetes preventionMeta-Analysisn=1,319 · large study2023
In plain English: Evidence from seven studies shows that antenatal dietary supplementation with myo-inositol during pregnancy may reduce the incidence of gestational diabetes, hypertensive disorders of pregnancy and preterm birth.
Motuhifonua SK et al. · The Cochrane database of systematic reviews (2023)
Huge benefit
← WorseNo effectBetter →
For the primary neonatal outcomes, only one study measured the risk of a large-for-gestational-age infant and found myo-inositol was associated with both appreciable benefit and harm (RR 1.40, 95% CI 0.65 to 3.02; 1 study, 234 infants; low-certainty evidence).
Further, myo-inositol may result in little to no difference in caesarean section (RR 0.91, 95% CI 0.77 to 1.07; 4 studies, 829 women; low-certainty evidence).
For the secondary neonatal outcomes, meta-analysis showed no neonatal hypoglycaemia (RR 3.07, 95% CI 0.90 to 10.52; 4 studies; 671 infants; very low-certainty evidence).
3Body weight and BMI reductionMeta-Analysisn=2,362 · very large study2023
In plain English: Carnitine was relatively effective in reducing body mass, while chromium, Omega-3, and selenium were beneficial for improving glucose metabolism.
Hu X et al. · PeerJ (2023)
The network meta-analysis showed that carnitine, inositol, and probiotics reduced body weight and body mass index (BMI) compared to placebo, and carnitine outperformed the other supplements (SUCRAs: 96.04%, 97.73%, respectively).
Omega-3 lowered fasting blood glucose (FBG) (SUCRAs: 93.53%), and chromium reduced fasting insulin (FINS) (SUCRAs: 72.90%); both were superior to placebo in improving insulin resistance index (HOMA-IR), and chromium was more effective than Omega-3 (SUCRAs: 79.99%).
Selenium was potent in raising the quantitative insulin sensitivity index (QUICKI) (SUCRAs: 87.92%).

Shang Y et al. · Advances in nutrition (Bethesda, Md.) (2024)
The results showed that use of antioxidants not only significantly increased the number of retrieved oocytes and high-quality embryo rates but also reduced the dose of gonadotropin, contributing to higher clinical pregnancy rates.
Appropriate antioxidant treatment should be offered at a low dose according to the patient's age and ovarian reserve.
5IVF/ICSI outcomes and OHSS reductionMeta-Analysisn=1,827 · large study2024
In plain English: Metformin and myoinositol may reduce OHSS risk in PCOS patients but did not significantly improve pregnancy outcomes.
Lin L et al. · Journal of ovarian research (2024)
Huge benefit
← WorseNo effectBetter →
Myoinositol was linked to a shorter gonadotropin duration (SMD = -1.21, 95% CI -2.03 to -0.38) and fewer side effects (OR = 0.23, 95% CI 0.06-0.83) compared to controls.
Metformin led to lower E2 levels, a higher number of mature oocytes, and increased side effects (SMD = -376.52, 95% CI -610.83 to -142.22; SMD = 2.23, 95% CI 0.36-4.10; OR = 6.85, 95% CI 4.32-10.86) than controls.
Metformin and myoinositol may reduce OHSS risk in PCOS patients but did not significantly improve pregnancy outcomes.
6Regular menstrual cycle in PCOSMeta-Analysisn=1,691 · large study2023
In plain English: Inositol is an effective and safe treatment in PCOS.
Greff D et al. · Reproductive biology and endocrinology : RB&E (2023)
Huge harm
← WorseNo effectBetter →
In patients treated with inositols, the risk (CI: 1.13; 2.85) of having a regular menstrual cycle was found by 1.79 higher than in the case of placebo.
7Menstrual frequency improvementMeta-Analysisn=1,079 · large study2021
In plain English: Ours is the first study to report that for women with PCOS, myo-inositol combined with D-chiro-inositol and metformin combined with thiazolidinediones appear superior to metformin alone in improving insulin resistance and decreasing total testosterone.
Zhao H et al. · Reproductive health (2021)
Huge harm
← WorseNo effectBetter →
Compared with metformin, treatment with myo-inositol + D-chiro-inositol was associated with a greater improvement in menstrual frequency (odds ratio 14.70 [95% confidence interval (CI) 2.31-93.58]).
Ours is the first study to report that for women with PCOS, myo-inositol combined with D-chiro-inositol and metformin combined with thiazolidinediones appear superior to metformin alone in improving insulin resistance and decreasing total testosterone.
Myo-inositol combined with D-chiro-inositol is particularly efficacious in menstrual recovery.
8Cycle regularization in PCOSMeta-Analysisn=388 · medium study2025
In plain English: In this meta-analysis of RCTs, combination therapy was associated with cycle regularization and reduction in hirsutism and LH/FSH ratio compared to metformin monotherapy.
Kelly FA et al. · Endocrine (2025)
Differences in acne (p = 0.58), body mass index (p = 0.13), fasting blood glucose (p = 0.07) and HOMA-IR (p = 0.25) were not statistically significant.
In this meta-analysis of RCTs, combination therapy was associated with cycle regularization and reduction in hirsutism and LH/FSH ratio compared to metformin monotherapy.
Further studies are needed to clarify the true benefits of the use of inositol in PCOS treatment.
9Live birth ratesMeta-Analysisn=4,451 · very large study2017
In plain English: Our updated review suggests that metformin alone may be beneficial over placebo for live birth, although the evidence quality was low.
Morley LC et al. · The Cochrane database of systematic reviews (2017)
No clear effect
← WorseNo effectBetter →
Metformin versus placebo or no treatmentThe evidence suggests that metformin may improve live birth rates compared with placebo (OR 1.59, 95% CI 1.00 to 2.51, 4 studies, 435 women, I2 = 0%, low-quality evidence).
There was no clear evidence of a difference in miscarriage rates (OR 1.08, 95% CI 0.50 to 2.35, 4 studies, 748 women, I2 = 0%, low-quality evidence).
However, the combined therapy group had higher rates of clinical pregnancy (OR 1.59, 95% CI 1.27 to 1.99, 16 studies, 1529 women, I2 = 33%, moderate-quality evidence) and ovulation (OR 1.57, 95% CI 1.28 to 1.92, 21 studies, 1624 women, I2 = 64%, moderate-quality evidence).
10Live birth rateMeta-Analysisn=7,760 · very large study2020
In plain English: In this review, there was low- to very low-quality evidence to show that taking an antioxidant may benefit subfertile women.
Showell MG et al. · The Cochrane database of systematic reviews (2020)
Huge harm

Likely real
Due to the very low-quality of the evidence we are uncertain whether antioxidants improve live birth rate compared with placebo or no treatment/standard treatment (odds ratio (OR) 1.81, 95% confidence interval (CI) 1.36 to 2.43; P < 0.001, I2 = 29%; 13 RCTs, 1227 women).
This suggests that among subfertile women with an expected live birth rate of 19%, the rate among women using antioxidants would be between 24% and 36%.
Low-quality evidence suggests that antioxidants may improve clinical pregnancy rate compared with placebo or no treatment/standard treatment (OR 1.65, 95% CI 1.43 to 1.89; P < 0.001, I2 = 63%; 35 RCTs, 5165 women).
17Hormonal and metabolic parameters in PCOSMeta-Analysisn=460 · medium study2023
In plain English: Our meta-analysis comparing hormonal and metabolic parameters between MET and MI did not show much significant difference, indicating both drugs are equally beneficial in improving metabolic and hormonal parameters in patients with PCOS.

Antioxidants versus placebo in adolescents There was little to no difference in treatment response between antioxidant (50%) and placebo groups (25%) after six weeks, based on a single trial of silymarin (RR 2.00, 95% CI 0.28 to 14.20; 8 participants; low-certainty evidence).
Antipsychotics versus placebo in adults There may be greater treatment response in the antipsychotic group (85%) compared to the placebo group (17%) after 12 weeks, based on a single trial of olanzapine (RR 5.08, 95% CI 1.4 to 18.37; 25 participants; low-certainty evidence).
Cell signal transducers versus placebo in adults There was little to no difference in treatment response between cell signal transducer (42.1%) and placebo groups (31.6%) after 10 weeks, based on a single trial of inositol (RR 1.33, 95% CI 0.57 to 3.11; 38 participants; low-certainty evidence).
