Natalie is a London-based neuroscientist, clinical psychologist, and biohacker specializing in the gut-brain axis and longevity. She holds an MSc in bioscience innovation from UCL with triple distinction, where her dissertation explored how probiotics, postbiotics, amino acids, and peptides improve sleep quality and recovery. She now collaborates with the Longevity Clinic on peptide formulation, bridging cutting-edge science with everyday biohacking to help people not just live longer, but live brighter.

What We Discussed:

1. Why 90% of your serotonin is made in your gut—and how gut inflammation destroys your sleep architecture
2. The four "languages" your gut and brain use to communicate (neural, metabolic, hormonal, immune)
3. Daily habits silently wrecking your microbiome: late-night snacking, artificial sweeteners, alcohol, and antibiotics
4. The 3-step gut repair protocol: repair the lining, repopulate with the right bacteria, rethink your lifestyle
5. Why postbiotics beat probiotics for immediate results—and the best peptides for deep sleep (DSIP, Selank, BPC-157)
