Garlic tablets improved several metabolic markers in women with PCOS and metabolic syndrome
A short randomized trial reported favorable changes in blood sugar, lipids and other measures, but does not establish lasting clinical benefits.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
Women receiving garlic tablets showed favorable changes in several metabolic measures compared with placebo, including fasting blood sugar and blood lipids. The trial also reported improvements in quality of life and sexual function. These findings apply to women with both PCOS and metabolic syndrome and do not establish prevention of diabetes or cardiovascular disease.
The authors note short follow-up, limited dietary control and missing hormone tests. This abstract-based summary cannot establish persistence of the effects or translate marker changes into fewer future health problems.
What researchers found
Fasting blood sugar
Garlic tablets versus placebo after 8 weeks; the abstract reports a statistically significant difference.
Several outcomes changed
The abstract reports reductions in blood pressure, weight and an inflammation marker, alongside changes in blood sugar and lipids. Waist-to-hip ratio did not change significantly, so the findings were not uniformly positive across every measured outcome.
Questionnaires add another perspective
Participants also reported improvements across the assessed sexual-function and PCOS-related quality-of-life domains. These measures broaden the picture beyond laboratory tests, but they do not show that the intervention resolved PCOS or its long-term complications.
