About this trial
The goal of this clinical trial is to learn if a postbiotic supplement can reduce stomach and gut symptoms in physically active women.
The main questions it aims to answer are:
Does the supplement reduce gut symptoms during the menstrual cycle? Does it improve symptoms related to exercise?
Researchers will compare the postbiotic supplement to a placebo (a look-alike capsule that contains no active ingredient) to see if the supplement works.
Participants will be physically active, premenopausal female athletes.
Participants will:
Take either the postbiotic supplement or a placebo each day for two menstrual cycles Track their menstrual cycle and training Report gut symptoms using regular questionnaires Provide stool samples to assess gut health
This study will help researchers understand whether postbiotic supplements can improve gut health and reduce symptoms that may affect training and performance in female athletes.
