Summary

This study is testing whether a daily supplement made from baker's yeast can improve digestion and reduce gut symptoms in healthy adults aged 50 to 99. Participants take 15 grams of the supplement each day and report any changes in how their stomach feels. The goal is to see if this yeast extract acts as a prebiotic to support a healthier gut.
