The usual part of that is I'm joined by my fantastic colleague in arms, the wonderful, the exceptional, the truly brilliant, the extraordinary, Dr. Eti

and can probiotic interventions actually improve sleep quality? Oh, so it's an interesting topic because I remember maybe it was eight years

ago. I think it was Josie Brassad with Ken Wright at the University of Boulder, Colorado. They did

some of the first work in this. And this is when people were only just starting to hear about the gut
