About

This study will look at whether a reduced-calorie Mediterranean-style eating plan, together with a synbiotic supplement, can improve health measures and quality of life in women who have polycystic ovary syndrome (PCOS) and are overweight or have obesity. Participants will be assigned by chance (like flipping a coin) to receive either the synbiotic supplement or a placebo (a look-alike product with no active ingredients). All participants will follow the same reduced-calorie Mediterranean diet for 8 weeks. The study team will measure body composition and weight-related measurements, and will collect blood samples to evaluate selected laboratory markers before and after the 8-week period. Participants will also complete the PCOSQ-50 quality-of-life questionnaire before and after the intervention. The goal is to better understand the possible role of synbiotic supplementation alongside dietary treatment in PCOS.

Full description

This randomized, placebo-controlled, single-blind clinical trial is designed to evaluate the effects of a hypocaloric Mediterranean diet combined with synbiotic supplementation on anthropometric measurements, biochemical parameters, and quality of life in overweight and obese women diagnosed with polycystic ovary syndrome (PCOS). Eligible participants will be randomly assigned to one of two study arms: a synbiotic supplementation group or a placebo group. Both groups will follow the same hypocaloric Mediterranean diet throughout the 8-week intervention period.

Anthropometric assessments, including body weight, body mass index, waist circumference, and body composition, will be performed at baseline and at the end of the intervention. Biochemical parameters will be evaluated through blood samples collected at baseline and after 8 weeks. Quality of life will be assessed using the PCOSQ-50 Quality of Life Questionnaire at both time points.

The study aims to determine whether the addition of synbiotic supplementation to a hypocaloric Mediterranean diet provides additional benefits in the management of PCOS-related metabolic parameters and quality of life compared with dietary intervention alone.
