How to Use Probiotics to Improve Your Health

April 6, 2019

Dr. Jason Hawrelak, PhD. is a researcher, educator, and clinician, specializing in gastrointestinal health, the gut microbiota and the use of probiotics to improve health outcomes. Jason has written extensively in the medical literature on these topics and has been in clinical practice for almost 20 years. He also coordinates and teaches the Evidence-based Complementary Medicine Program at the University of Tasmania in Australia.

In this podcast, Jason and I discuss probiotics: what they are, what they do, and how to use them to improve your health. Jason talks about assessing the gut microbiota, some common misconceptions about probiotics, and specific strains to look for that are backed by research. He also discusses his industry-independent, evidence-based online courses and database, created to help guide clinical practice.
