# Amanda Callenberg Nutrition
Amanda Callenberg is a London-based Gut Health Nutritionist and Registered Nutritional Therapist (BANT, CNHC) specialising in chronic digestive conditions, particularly IBS, SIBO, and complex gut issues linked to nervous system dysregulation. She works exclusively with women experiencing persistent, unpredictable gut symptoms that haven't resolved through conventional diets, elimination approaches, or standard medical interventions.
Her distinctive Mind-Body-Biome™ method integrates personalised nutritional therapy, functional medicine testing, and targeted nervous system support—recognising that returning symptoms rarely stem from food alone. Amanda addresses the gut-brain axis connection, understanding how stress physiology and emotional patterns directly influence digestion. Rather than prescribing generic protocols, she investigates what's actually driving each client's symptoms through advanced functional testing and compassionate inquiry-informed approaches.
What sets her apart is her experience-informed, somatic-aware practice that treats the whole person rather than isolated symptoms. She combines evidence-based nutrition with nervous system awareness and psychological insight, acknowledging that digestive health recovery requires addressing mind, body, and gut microbiome simultaneously. Her clients are typically those frustrated by temporary improvements or symptom-shifting, seeking deeper understanding and sustainable resolution.
Amanda offers online 1:1 support, providing accessible expert care regardless of location, with a track record of 4.8-star Google ratings reflecting her client outcomes.
