What this trial studies

Women aged 18–40 with newly diagnosed PCOS will be randomly assigned for three months to one of three once-daily regimens: metformin alone, metformin plus quercetin (500 mg), or metformin plus sustained-release alpha-lipoic acid (600 mg). Fasting blood samples at baseline and month 3 will measure hormones, glucose/insulin, lipids, and oxidative-stress markers, while weight, blood pressure, and side effects will be recorded. Participants will complete the PCOSQ quality-of-life questionnaire and a 4-item medication adherence scale at both visits. The randomized, parallel-group design compares metabolic, hormonal, antioxidant, and patient-reported outcomes between regimens to judge safety and benefit.

Who should consider this trial

Good fit: Ideal candidates are women 18–40 with newly diagnosed PCOS defined by polycystic ovaries on ultrasound, oligomenorrhea, clinical or biochemical hyperandrogenism, normal prolactin, and no diabetes or other major endocrine or cardiovascular conditions.

Not a fit: Patients who are pregnant, have diabetes or other excluded comorbid endocrine or cardiovascular diseases, are already taking hormonal or lipid-lowering therapies, or cannot attend the Baghdad study site are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, adding quercetin or ALA could offer a low-cost way to improve hormonal balance, metabolic health, and quality of life for women with PCOS.

How similar studies have performed: Small clinical and preclinical studies suggest quercetin and ALA can improve insulin resistance, lipid profiles, and oxidative-stress markers, but large randomized trials in PCOS are limited.
