Efficacy of Alpha Lipoic Acid Combined With Myo-Inositol in Non-Diabetic PCOS Patients (ALA-MYO-PCOS)

June 2, 2026 updated by: Ahmed Abdelkader, Beni-Suef University

A Randomized Controlled Trial Evaluating the Efficacy of Alpha Lipoic Acid Combined With Myo-Inositol With or Without Metformin in Non-Diabetic Women With Polycystic Ovary Syndrome

This study evaluates the efficacy of alpha-lipoic acid combined with myo-inositol, with or without metformin, in improving menstrual regularity and ovulation in non-diabetic women with polycystic ovary syndrome (PCOS). The study also assesses metabolic, hormonal, and clinical outcomes.

Study Overview

Detailed Description

This is a prospective randomized controlled parallel-group clinical trial evaluating the effects of alpha-lipoic acid combined with myo-inositol, with or without metformin, in women with polycystic ovary syndrome (PCOS).

A total of 180 patients will be randomized into three groups:

Myo-inositol with folic acid Myo-inositol + alpha-lipoic acid Myo-inositol + alpha-lipoic acid + metformin

The study duration is 6 months. Outcomes include menstrual regularity, ovulation rate, hormonal parameters, metabolic markers, and clinical signs of hyperandrogenism.
