Young poop pills could boost brain and brawn in seniors

This early-stage study tests whether transplanting gut bacteria from young, physically active donors into older adults (ages 65-84) can help preserve muscle strength, thinking skills, and metabolic health. The treatment uses freeze-dried capsules taken by mouth. The goal is to see if restoring a more youthful gut microbiome can slow age-related decline. The study involves 80 participants and focuses on safety and changes in strength, mobility, and cognition.
