Effects of Adding Quercetin or Alpha Lipoic Acid to Usual Care on Symptoms and Blood Markers in Iraqi Women With Polycystic Ovary Syndrome

September 18, 2025 updated by: Mohammed Mahmood Mohammed, Al-Mustansiriyah University

Impact of Adding Quercetin or Alpha Lipoic Acid as an Adjuvant Therapy on Clinical and Biochemical Outcomes in a Sample of Iraqi PCOS Patients

This study will investigate whether the addition of Quercetin or Alpha-Lipoic Acid (ALA) to standard metformin therapy can improve symptoms, hormone levels, metabolic health, and quality of life in women with polycystic ovary syndrome (PCOS). Over 3 months, participants will be randomly assigned to one of three groups: metformin alone, metformin plus Quercetin, or metformin plus ALA. Researchers will measure changes in hormones, blood sugar, cholesterol, and antioxidant markers, as well as quality of life and medication adherence. Physical measurements and side effects will also be recorded to assess safety and overall benefit.

Study Overview

Detailed Description

The goal of this clinical trial is to learn if adding Quercetin or Alpha-Lipoic Acid (ALA) to metformin can better treat PCOS symptoms and improve safety, metabolic health, and quality of life in women.

The main questions it aims to answer are:

  • Does metformin + Quercetin or metformin + ALA improve hormonal balance (e.g., LH, FSH, testosterone) more than metformin alone?
  • Do these combinations enhance glycemic control (fasting glucose, insulin, HOMA-IR), lipid profiles, and oxidative-stress markers (fibulin-1, kisspeptin, SOD1, GPx)?
  • How do these regimens affect patient-reported outcomes like quality of life (PCOSQ) and medication adherence?

Researchers will compare three groups to see which regimen yields the greatest improvements:

  • Metformin 500 mg daily alone
  • Metformin 500 mg + Quercetin 500 mg daily
  • Metformin 500 mg + ALA 600 mg SR daily

Participants will:

  • Take their assigned oral treatments once daily after a meal for 3 months
  • Provide fasting blood samples at baseline and month 3 for hormone, glucose/insulin, lipid, and antioxidant assays
  • Complete the PCOSQ quality-of-life questionnaire and the 4-item Morisky adherence scale at both visits
  • Undergo physical measurements (weight, BMI, waist/hip circumference, blood pressure) and report any side effects

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Hormonal Profile (LH, FSH, Testosterone) from Baseline
Time Frame: Baseline and 3 months after starting assigned treatment
Serum luteinizing hormone (LH), follicle-stimulating hormone (FSH), and total testosterone levels will be measured in fasting blood samples. Changes from baseline to 3 months will be compared between groups to assess improvement in hormonal balance in women with PCOS.
Baseline and 3 months after starting assigned treatment
Change in Glycemic Control Markers (Fasting Glucose, Insulin, HOMA-IR) from Baseline
Time Frame: Baseline and 3 months after starting assigned treatment
Fasting plasma glucose and insulin will be measured, and the Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) will be calculated. Changes from baseline to 3 months will be compared between groups to evaluate improvements in glycemic control.
Baseline and 3 months after starting assigned treatment

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Lipid Profile (Total Cholesterol, LDL-C, HDL-C, Triglycerides) from Baseline
Time Frame: Baseline and 3 months after starting assigned treatment
Fasting lipid panel will be assessed, including total cholesterol, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglycerides. Changes from baseline to 3 months will be compared between groups.
Baseline and 3 months after starting assigned treatment
Change in Oxidative Stress and Related Biomarkers (Fibulin-1, Kisspeptin, SOD1, GPx) from Baseline
Time Frame: Baseline and 3 months after starting assigned treatment
Serum levels of fibulin-1, kisspeptin, superoxide dismutase 1 (SOD1), and glutathione peroxidase (GPx) will be measured in fasting blood samples. Changes from baseline to 3 months will be compared between groups to assess antioxidant and oxidative stress status.
Baseline and 3 months after starting assigned treatment
Change in Quality of Life (PCOSQ Total Score) from Baseline
Time Frame: Baseline and 3 months after starting assigned treatment
The Polycystic Ovary Syndrome Health-Related Quality of Life Questionnaire (PCOSQ) will be administered. Changes in total score from baseline to 3 months will be compared between groups to evaluate patient-reported well-being.
Baseline and 3 months after starting assigned treatment
Change in Medication Adherence (4-Item Morisky Scale Score) from Baseline
Time Frame: Baseline and 3 months after starting assigned treatment
The 4-item Morisky Medication Adherence Scale will be used to assess adherence to assigned treatment. Changes in score from baseline to 3 months will be compared between groups.
