Let’s unpack the world of probiotics. What they are, how they work, and who might actually benefit from taking them.


Today you’ll learn about the science behind probiotic strains, explore whether fermented foods like kefir and kimchi are enough, and discuss when probiotics may help with issues like IBS, supporting our immune health, or even preventing antibiotic related side effects.


To help us with this complicated topic, we have Dr Megan Rossi on the show today. She’s the founder of The Gut Health Doctor®, and is one of the most influential gut health specialists internationally, and a leading Research Fellow at King’s College London. She’s a registered dietitian and nutritionist but Dr Megan has an award-winning PhD in Probiotics.


She is also the founder of the gut health food brand, Bio&Me, and she has launched a targeted range of clinically-proven live bacteria supplements, SMART STRAINS®.


Dr Megan also shares how to navigate the supplement aisle with confidence, what to look for on a label (such as the Genus, Species and Strain), and how probiotics compare to other foods with probiotic-like effects and other foundational gut health habits like fibre and plant diversity.


There is no financial affiliation of any kind with Doctor’s Kitchen and Dr Megan’s brand of probiotics.
