Meet Keith Ngan MRPharmS – Pharmacist, Author & Eye Nutrition Specialist
Keith Ngan MRPharmS is a UK registered pharmacist with more than 25 years of experience in healthcare, specialising in eye health and ocular nutrition. He is the Co-Founder and Chief Pharmacist of Intelligent Formula, the British company behind the trusted Vision Defender range of eye health supplements.
Keith is registered with the General Pharmaceutical Council (GPhC) and is a full Member of the Royal Pharmaceutical Society (MRPharmS). He studied at the School of Pharmacy, University of London, now part of University College London (UCL) – one of the UK’s leading pharmacy schools.
Author of ‘Help! What Vitamins Should I Take for My Eyes?’
Keith is also the author of Help! What Vitamins Should I Take for My Eyes?, a practical, easy-to-follow guide designed to help readers understand which eye supplements work, why they work, and how to choose them confidently.
Written in clear, jargon-free language, the book explains essential research like the AREDS2 study, breaks down common eye conditions such as macular degeneration, and cuts through confusing supplement marketing with straightforward advice. Keith’s writing reflects his commitment to helping people make informed health decisions based on science, not sales claims.
A Personal Journey into Eye Health
Keith’s passion for eye health is deeply personal. After close family members developed age-related vision problems, he began researching how nutrition could play a role in preserving eyesight and supporting long-term eye health.
This experience led him to co-found Intelligent Formula, a specialist UK nutraceutical company focused on developing evidence-based eye health supplements. Every Vision Defender product is formulated under Keith’s direction and rooted in clinical research — especially landmark studies like AREDS2.
Trusted Expertise Backed by Experience
As Chief Pharmacist, Keith ensures all products meet the highest standards of safety, scientific accuracy, and regulatory compliance. He brings together his pharmacy background and personal mission to support eye health naturally, responsibly, and ethically.
His blend of professional credibility and personal insight has made Keith a trusted source of information for customers, eye care professionals, and the growing community of people looking to protect their vision through nutrition.
Beyond the Lab Coat
Outside of his professional life, Keith enjoys all things tech and is often found trying out new gadgets. He’s also a passionate foodie and loves discovering new restaurants and culinary experiences — a well-earned break from the world of eye health and clinical studies.
