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?

    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+.
