YDS is supported by ⁠⁠Microcosm Coaching. ⁠

Kylee and Zoë take a magic school bus ride into the microbiome! We go back (waaay back) into the origins of the human microbiome and examine the research on how gut biota affects and interplays with athletic performance. Put your gloves on, because we’re digging into Zoë’s microbiome to get to know her on a very, very intimate level (the microbial level!). We also discuss common and uncommon causes of GI distress and what athletes can do to support their gut health (spoiler alert: you probably don’t need all that kombucha).
