Energy & Cognitive
Restore your energy, enhance cognitive performance, and support long-term cellular health with our doctor-led NAD+ intravenous therapy
Choose your option
NAD+ (Nicotinamide Adenine Dinucleotide) is a vital coenzyme required for energy production, DNA repair, and healthy ageing. Our advanced IV therapy delivers NAD+ directly into the bloodstream for optimal absorption and immediate cellular benefit.
As we age, NAD+ levels naturally decline, leading to decreased cellular energy and cognitive fatigue. Our clinical protocol bypasses the digestive system to saturate your cells with this essential coenzyme.
Choose your NAD+ option from the pricing panel. 500mg and 1000mg are part of a programme. See programme and Advanced NAD+ Protocol prices.
Typically administered over multiple sessions for optimal comfort and results. Suitability determined during private consultation.
While single sessions provide a noticeable boost, a structured course allows for a deeper physiological shift.
Most patients begin to experience significant and lasting improvements after multiple sessions, which is why our medical team typically recommends a course of treatment. View programmes & prices
Ideal for those seeking peak optimization:
NAD+ is administered intravenously, bypassing the digestive system and ensuring maximum bioavailability. Once in the bloodstream, NAD+ works at a cellular level to support the mitochondria, the energy-producing centres of your cells helping to restore and optimise cellular function.
Infusions are delivered slowly to ensure comfort and optimal absorption, particularly at higher doses.
At Marylebone Diagnostic Centre, NAD+ therapy is delivered as part of a medical, personalised protocol not a one-size-fits-all treatment.
Supports cellular energy, DNA repair, and overall metabolic function. Prepared in our CQC-regulated clinic using high-quality, medical-grade ingredients.
To maximise and maintain your NAD+ levels between IV treatments, we recommend incorporating a convenient at-home option alongside your in-clinic therapy.
While NAD+ IV therapy delivers the most powerful and immediate cellular restoration, maintaining those levels between sessions can further optimise your results.
Consult with our clinicians to find the right at-home protocol to complement your IV programme.
We’ve partnered with VAION to provide patients with access to high-quality, easy-to-use NAD+ delivery options to maintain cellular function between clinic visits.

A highly efficient method for supporting NAD+ levels and maintaining cellular function at home.

A simple, needle-free daily option for supporting energy, focus, and rapid cognitive recovery.
Our clinical recommendation: Combine periodic NAD+ IV therapy with regular at-home support for optimal results.
