About Sarah
Hi, I’m Sarah, a Registered Nutritional Therapist (mBANT, CNHC Reg) and Clinician, with a BSc (Hons) degree in Nutritional Therapy, and a 20-year career in women’s health and wellbeing.
I began my career working at the world’s leading global health and beauty companies including Unilever, L'Oréal, and Estée Lauder, where I saw first-hand how often women are offered solutions that only scratch the surface. My perspective on health became deeply personal when my sister was diagnosed with acute myeloid leukaemia and I became her life-saving stem cell donor - an experience that transformed how I understood the body’s remarkable resilience, and led to the founding of the award-winning brand By Sarah, alongside formal clinical training in functional nutrition and lifestyle medicine.
Today, I work one-to-one with clients who want to feel better, think clearer, and live with vitality. My focus is simple: to help you build a way of eating and living that supports your body, fits your lifestyle, and empowers you to thrive - without confusion, overwhelm, or restriction.
Qualifications
Sarah Murrell, Registered Nutritional Therapist (BSc Hons, mBANT, CNHC Reg)
Distinction in Biology, Chemistry, and Anatomy & Physiology (Level 3 Advanced).
My qualification as a Registered Nutritional Therapist (mBANT, CNHC Reg) involved 4 years of rigorous study in functional nutrition and comprehensive clinical practice, including a final year dissertation on the topic of IBS, which was graded a 1st. That depth of training underpins all the protocols and precision-led plans that I create in my clinic today.
