About Us

Nadcell Mindcare is a UK based pioneering clinic that provides innovative treatments & digital therapies proven to reduce stress, increase clarity and improve mental wellbeing.


Whether you are dealing with stress, anxiety, depression, insomnia, behavioural issues, addictions, or a wide range of other issues (see what we treat here) we are confident that we can help you.

The Nadcell Mindcare team consists of highly qualified clinicians led by Dr Alexander Lapa, the foremost authority on NAD+ cell therapy in the UK; John Gillen, and an exceptional supporting staff.

Together we have a great many years of experience in supporting patients with anxiety related disorders under our belt, and have made creating better mental health our lifelong passion.

Over the years of treating hundreds of patients from all walks of life, we desperately wanted to provide each and every one of them with a more sustainable long-term solution.

So we started searching, testing and reviewing new and innovative ways to help people maintain their mental health and sobriety.

What we found was better than we could have hoped.

We have witnessed first-hand how the therapies we now provide under 1 roof at Nadcell Mindcare gave blissful relief to those who thought that a constant state of anxiety was just how their life was always going to be.

Mr. John Gillen

European Pioneer of NAD+

Founder | John Gillen

For over a decade, he has travelled the world to obtain answers. This led to the realisation that the co-enzyme NAD+ (Nicotinamide adenine dinucleotide) was the central metabolite required for cell function. John explains it quite simply as being the “miracle molecule”, finding scientific evidence for this cellular fuel and realising the potential for numerous conditions with NAD+ as the vital component for regenerative medicine.” NADCELL now offers NAD+ intravenous therapy. John was the first pioneer to bring NAD+ treatment to Europe in 2013. His passion extends to other metabolic disturbances and neurodegenerative diseases.

The journey continues; in recent times, John has travelled to Russia to study and research a new therapy known as photobiomudulation, or intravenous laser and ultra violet therapy, working with scientists and the very best of medical professionals in the UK. Together with Nadcell Clinic’s own select doctors, nurses, dieticians and therapists, John’s passion continues to bring to the UK new ways of helping clients with restorative medicine and wellness. In 2017, John Gillen became a visiting professor at the John Naisbitt university in Belgrade, Serbia.
