This randomized, triple-blind trial gives daily oral supplements for 12 weeks to women with PCOS. Participants are assigned to magnesium alone, magnesium plus levocarnitine, or placebo. Measurements (blood tests, body measures, and hirsutism score) are done at the start and end of the 12-week period.
What it is studying. The study is testing whether taking magnesium and levocarnitine supplements affects glycemic control (fasting blood sugar, insulin, HbA1c, HOMA-IR), lipid levels, and hirsutism in women with PCOS. It compares three groups — magnesium alone, magnesium plus levocarnitine, and placebo — over a 12-week treatment period.
What the researchers hope to learn. Scientifically, the trial aims to measure whether magnesium with or without levocarnitine changes fasting glucose and other glycemic markers, insulin resistance, cholesterol and triglyceride levels, and hirsutism in women with PCOS. The results are intended to inform future research and understanding of these supplements in PCOS.
What this study is about
The study's own summary, as published on ClinicalTrials.gov. Underlined terms have a short explanation.
Polycystic Ovary Syndrome (PCOS) is one of the most common endocrine disorders among women of reproductive age and is associated with metabolic abnormalities such as insulin resistance, dyslipidemia, and hormonal imbalance, which may lead to infertility and hirsutism. Despite the availability of several pharmacological treatments, many therapies fail to effectively address the underlying metabolic and endocrine dysfunctions of PCOS. Magnesium and L-carnitine are two essential nutrients that may play a synergistic role in improving insulin sensitivity, glucose metabolism, and lipid profile, as well as reducing oxidative stress and androgen production in women with PCOS. This randomized, triple-blind, placebo-controlled clinical trial aims to evaluate the effects of co-supplementation with magnesium and L-carnitine on glycemic control indices, lipid profile, and hirsutism in women with PCOS. A total of 84 eligible women aged 19-65 years diagnosed with PCOS according to the Rotterdam criteria will be recruited from Shohada Tajrish Hospital, Tehran, Iran. Participants will be randomly assigned to one of three groups: (1) magnesium supplementation (500 mg/day, in two 250 mg doses) plus L-carnitine placebo, (2) L-carnitine supplementation (1000 mg/day) plus magnesium (500 mg/day), or (3) placebo control group. The intervention period will last 12 weeks. Physical activity information will be collected using short form of International Physical Activity Questionnaire (IPAQ) and demographic information through a general information questionnaire. In order to evaluate dietary intake of patients in terms of energy(kcal/(day), carbohydrate(gr/day), protein(gr/day), fat intake(gr/day), saturated fatty acids (SFA) (gr/day), monounsaturated fatty acids (MUFA) (gr/day), polyunsaturated fatty acids (PUFA)(gr/day), Vitamin E (mg/day), Vitamin C (mg/day), Beta-carotene (mg/day) and Vitamin A (mg/day), cupper intake (mg/day), selenium intake (mg/day), and zink intake (mg/day), 24-hr recalls will be completed by interviewing the patient for 3 days (two normal days and a weekend day). Weight will be measured with the minimum dress and without shoes by using a digital balance scale of 100 grams and height will be measured without shoes by meters mounted to the wall with an accuracy of 0.5 centimeters. Then the body mass index will be calculated by dividing the weight (kg) by the square of the height (m), waist circumference will be measured in the narrowest area between the lowest lumbar spine and the iliac bone (cm), systolic and diastolic blood pressure will be measured after 15 minutes of rest, twice using the mercuric barometric measure and the mean will be reported as individual blood pressure. The blood sample will be taken after 12 hours of overnight fasting in three groups for measuring Fasting Blood Sugar (FBS) (mg/dL), lipid profile (mg/dL), Hemoglobin A1c (HbA1C) (percentage), serum insulin concentration (µIU/ml) and insulin resistance. Insulin resistance will be calculated using the Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) formula, and hirsutism score (using the modified Ferriman-Gallwey method) will be assessed at baseline and post-intervention. At the end of the study, counting the remaining capsules, the patient's compliance rate will be evaluated, and patients who have consumed less than 90% of their capsules will be excluded from the analysis.

Study description and what participation involves
The study's detailed description, as published on ClinicalTrials.gov.
Detailed description from the registry
This is a randomized, triple-blind, parallel clinical trial evaluates the effects of co-supplementation with Magnesium and Levocarnitine on metabolic and hormonal outcomes in women with Polycystic Ovary Syndrome (PCOS). Patients are randomly assigned into three groups and received magnesium supplementation (500 mg/day, in two 250 mg doses), L-carnitine supplementation (1000 mg/day), and placebo for 12 weeks. Then the body mass index, waist circumference, systolic and diastolic blood pressure, Fasting Blood Sugar (FBS), lipid profile, Hemoglobin A1c (HbA1C), serum insulin concentration and insulin resistance are measured; All assessments will be performed at baseline and at the end of the study.

You will be randomly assigned (triple-blind) to take daily capsules for 12 weeks: magnesium, levocarnitine plus magnesium, or placebo. Before and after the 12-week period you will have measurements (weight, height, waist circumference, BMI), blood pressure, and a fasting (12-hour) blood draw to measure fasting blood sugar, lipid profile, HbA1c, and serum insulin (used to calculate HOMA-IR), and your hirsutism score will be assessed using the modified Ferriman–Gallwey method. You will complete a short physical-activity questionnaire (IPAQ), a demographic questionnaire, and three 24‑hour dietary recalls (two normal days and one weekend day). At the end the study team will count remaining capsules to assess adherence; participants who consumed less than 90% of their capsules will be excluded from the analysis.
How the study is structured. This is a randomized, triple-blind, parallel interventional study. Women are randomly assigned to one of three daily oral supplement groups for 12 weeks. Key measurements (fasting blood tests for glucose, insulin and lipids, HbA1c, calculated HOMA‑IR, body weight and waist, blood pressure, and a hirsutism score) are taken at baseline and after 12 weeks; capsule counts are used to check adherence.
Questions you could ask
These questions are suggestions for a conversation with the study team or your own clinician, not advice.
- The registry lists this study under Polycystic Ovary Syndrome (PCOS). Does it apply to my diagnosis?
- Some participants receive a placebo. How is that decided, and what happens for placebo-group participants when the study ends?
- The listed sites are in Iran. Is any of them reachable for me, and does the study help with travel?
- Which of the eligibility criteria would need to be checked with tests before I could join?

Terms used on this page · explanations by MedicalUpdates.ai
- randomized
- Participants are assigned to the study groups by chance, like a coin toss, rather than chosen by the doctor or the participant. This is done so the groups are comparable.
- triple-blind
- Three types of people involved in the study do not know which intervention a participant is receiving. In a quadruple-masked study, four specified groups are masked. The registry record shows which groups these are.
- placebo-controlled
- A study design in which one group receives a placebo so that the study treatment's effects can be compared with no active treatment.
- placebo
- A treatment that looks like the study treatment but contains no active ingredient. Some participants receive it instead of the study treatment, usually without knowing which they got.
- control group
- The group the study treatment is compared with. It may receive a placebo, an existing treatment (active comparator), a sham procedure, or no intervention.
- baseline
- Measurements taken at the start of the study, before any study treatment, so that later results can be compared with them.
- Inclusion Criteria
- The conditions a person must meet to be considered for the study, for example a confirmed diagnosis, an age range or a test result.
- Exclusion Criteria
- The conditions that rule a person out even if they meet the inclusion criteria, for example other illnesses, certain medicines or pregnancy.
