Antony Underwood - Rethinking Probiotics: Evidence-Based Applications in Practice

In this episode of the MediHerb podcast, Laurence Katsaras is joined by Dr Antony Underwood, integrative paediatrician and cofounder of Spectrumceuticals, to explore the rapidly evolving science of probiotics and microbiome therapy. Together, they unpack strain specificity, probiotic research quality, taxonomy and trademarks, storage and stability, and how practitioners can apply evidence-based probiotic prescribing in clinical practice. The conversation also dives into probiotics in paediatric care and the first 1000 days, including applications for NEC prevention, colic, reflux, antibiotic-associated diarrhoea and immune resilience. Dr Underwood also shares insights into diet, polyphenols, fermented foods, postbiotics and emerging “keystone” bacteria shaping the future of personalised microbiome medicine.
