About Amanda Callenberg Nutrition
Amanda Callenberg is a Registered Nutritional Therapist (BANT, CNHC) and Somatic Counsellor who integrates personalised nutritional therapy, functional medicine, and targeted nervous system support to address the root causes of health concerns.
Specialising in gut health, Amanda works with clients experiencing IBS, SIBO, bloating, reflux and other persistent digestive symptoms, offering deeper support tailored to individual needs. Her approach combines nutritional assessment with functional testing when required—including GI360, SIBO testing, DUTCH hormone panels, and blood work—to build a complete picture of your health.
Beyond digestion, Amanda supports hormone health and uses nervous system-informed approaches, including Compassionate Inquiry and somatic awareness techniques, to help regulate your body's stress response. This mind-body-biome lens recognises that physical symptoms often have emotional and nervous system roots, and that lasting change requires addressing all three.
Initial consultations cover your health history, current symptoms, and goals, with follow-up sessions building a personalised plan. Whether you're seeking nutritional therapy, functional medicine consultation, hormone health support, or counselling that honours both body and mind, Amanda offers a thoughtful, evidence-informed approach to wellness.
