  • Iain De Havilland

    Founder & CEO

    Iain De Havilland is driven in his quest for “Living Well Longer” and constantly looking for ways to better improve our R.O.T (Return on Time).

    NADclinic Limited was established to utilise the technological advancements made within the IT sector to deliver highly efficient and class-leading nutrient & hydration infusion treatments to the general public on an “On Demand” basis.

    Since discovering NAD+ and the extraordinary & numerous benefits the super coenzyme offered him personally a couple of years ago, entrepreneur Iain decided to set up

  • Yuqi Feng


    Yuqi Feng is responsible for leading the company’s business operations, executing Nadclinic’s business strategy and ensuring operational excellence. Prior to joining NADclinic Ltd, Ms Feng was employed as Head of Asia Operations for SVS Securities Plc London since March 2015, and before this has enjoyed a long and distinguished career in Fintech & operations within the UK banking and finance sector. So what led me to become interested in a completely different field like nutrition, IV vitamins and Functional Medicine?

    “A couple of years I had a serious health problem that required an extensive number of medical tests. It turned out there wasn’t much I could take in terms of “conventional” medicine, so I started learning a lot about vitamins and nutrients. My goal was to apply that knowledge to improve my own health.”

    This is when I encountered Iain De Havilland and his passion for NAD+. Sure enough, NAD+ IV nutrient therapy did help and became a part of my overall approach to treatment that included other modalities like diet, NAD+ oral supplements and stress management. I am now fully recovered and have never felt more energised in my entire life. I am passionately looking forward to the years ahead, introducing & educating people around the globe to the amazing benefits and life-changing properties of NAD+.
