Assessment of the Effect of Magnesium and Levocarnitine Co-supplementation on Lipid Profile, Glycemic Control Indicators and Hirsutism in Women With Polycystic Ovarian Syndrome

Not applicable Interventional Science & Research Islamic Azad University Branch Khozestan · NCT07298564

This 12-week test will see if taking magnesium together with L-carnitine improves blood sugar, cholesterol, and excess hair in women aged 19–65 with PCOS.

What this trial studies

This randomized, triple-blind, parallel-group trial will enroll 84 women aged 19–65 diagnosed with PCOS by Rotterdam criteria and randomly assign them to magnesium (500 mg/day), L-carnitine (1000 mg/day), or placebo for 12 weeks. Primary measurements include BMI, waist circumference, blood pressure, fasting blood sugar, HbA1c, lipid profile, serum insulin, calculated insulin resistance, and hirsutism, taken at baseline and at the end of the intervention. Key exclusions include pregnancy or breastfeeding, menopause, hypothyroidism, significant liver or kidney disease, seizure or neuromuscular disorders, psychiatric conditions, and current therapeutic vitamin/mineral supplements. Outcomes will be compared between groups to determine whether supplementation produces greater metabolic or hormonal improvement than placebo.

Who should consider this trial

Good fit: Women aged 19–65 with PCOS diagnosed by Rotterdam criteria who are not pregnant or breastfeeding and do not have major liver, kidney, thyroid, neurological, or psychiatric disorders and are not taking therapeutic vitamin/mineral supplements.

Not a fit: Women who are menopausal, pregnant or breastfeeding, have hypothyroidism, significant liver or kidney disease, seizure or neuromuscular disorders, or who already take therapeutic supplements are unlikely to be eligible or to benefit from this protocol.

Why it matters

Potential benefit: If successful, the combination could provide a low-cost, well-tolerated option to improve insulin sensitivity, lipid profiles, and reduce hirsutism in women with PCOS.

How similar studies have performed: Prior small studies of magnesium or L-carnitine alone have reported modest improvements in insulin resistance and lipid measures, but combined supplementation in PCOS is less well studied and remains relatively novel.
