If you have been trying to make sense of what truly supports brain health, this episode is worth setting time aside. Barry Skillington is joined by Dr Kieran Rea, Atlantia’s Scientific Director, who brings years of experience across neuroscience, clinical trial design and the microbiota gut-brain field. Ciarán has led research teams in academia and industry, managed clinical trial portfolios in therapeutic areas such as neuroscience and immunology, and overseen translational work from early characterisation models through to human trials. Together, they unpack: ● Why so many people chase quick fixes, and why they rarely solve the root problem. ● How sleep, stress, exercise and routine drive mental clarity more than supplements ever can. ● What the gut–brain axis actually is, and how our microbiome signals to the brain through chemical pathways and the vagus nerve. ● Why digestion, meal timing, and even chewing influence nutrient absorption and energy. ● What really changes as the brain ages, and what we can do to keep it sharp throughout life. #StraightTalkingScience #BrainHealth #CognitiveFunction #GutBrainAxis #Microbiome #MentalWellbeing #HealthyAgeing #StressScience #SleepHealth #ExerciseScience #ClinicalResearch #AtlantiaClinicalTrials
