    180
The investigators are conducting a double-blinded randomized controlled trial to determine whether a probiotic mixture is effective in reducing PCOS-related symptoms. For this purpose, 180 participants will be recruited in three intervention arms (Probiotic, Placebo and Metformin), with 60 participants per arm. The intervention period will last 6 months, with extensive medical history, blood work, urine and stool analysis at the beginning and the conclusion of the trial.

Probiotic Experimental

Probiotic product consisting of these 7 bacterial strains: Lactobacillus salivarius W57 Lactobacillus casei W56 Lactobacillus rhamnosus W71 Lactococcus lactis W58 Enterococcus faecium W54 Lactobacillus plantarum W62 Lactobacillus acidophilus W22 Additional ingredients: Corn starch, maltodextrin, fructo-oligosaccharides, galacto-oligosaccharides, polydextrose, plant proteins, potassium chloride, magnesium sulfate, bacterial strains, manganese sulfate, lactose, 2000 IU vitamin D Participants ingest one sachet of powder (5 grams) in 200 ml of water per day for 6 months

Placebo Placebo Comparator

Similar to probiotic product in optics and smell, less ingredients and no bacterial strains or vitamin D Ingredients: Corn starch, maltodextrin, potassium chloride, magnesium sulphate, manganese sulphate

Metformin Active Comparator

Metformin is an established drug for treating PCOS-related symptoms. The investigators are comparing the probiotic not only to a placebo group, but also to the benchmark treatment. Participants in the metformin arm will start treatment with 500 mg daily for the first week, then increasing the dose to 2x500 mg daily for the duration of the intervention.
