Doctor-Designed Supplements UK — Created by a Practising NHS GP
Little Ox supplements are designed by Dr Chun Tang — a practising NHS and private GP with over 26 years of clinical experience. Not a marketing company. Not a celebrity brand. A real doctor who sees real patients every week and applies that clinical knowledge to every formula we produce.
Doctor-designed by Dr Chun Tang — MBChB (Manchester), MRCGP, MBA
Practising NHS & private GP, 26 years of clinical experience. GP at Pall Mall Medical (CQC-registered), Manchester. As featured in The Telegraph, The Mirror, The Independent and Women's Health.
What "Doctor-Designed" Actually Means at Little Ox
Many supplement brands use the phrase "doctor-formulated" as a marketing badge, attached to a consultant who reviewed the label once. At Little Ox, Dr Tang is the founder. He designs every formula based on what the clinical evidence supports, what his patients actually need, and what he uses himself. He also ensures every product claim meets MHRA and ASA requirements — no disease treatment claims, no unsubstantiated efficacy assertions.
The Clinical Credibility Difference
Dr Tang's clinical background spans Family Medicine, Emergency Medicine, Paediatrics, Gynaecology, Geriatrics and Rehabilitation. He has spent 26 years observing what declining health looks like in real patients — and what the evidence-based interventions are. This breadth of clinical experience directly informs the product range, from NMN Pure for NAD+ restoration to Shilajit Complex for male overall wellbeing to Magnesium Glycinate for sleep.
