NAD Subcutaneous Injection
Last updated: 10 July 2026
We are one of only a handful of NAD-certified clinics in Japan. NAD subcutaneous injection is an age-care treatment that aims to supplement NAD (nicotinamide adenine dinucleotide), a coenzyme involved in how cells produce energy, by injection under the skin. Levels of NAD in the body have been reported to fall with age, and this treatment is based on the idea of replenishing them.
About
About this treatment
What NAD is
NAD (nicotinamide adenine dinucleotide) is a coenzyme present in every cell, involved in producing energy and in cellular repair. Levels have been reported to decline with age, and it is an active subject of research in age-care and preventive medicine.
Why by injection
Compared with an IV drip, a subcutaneous injection takes far less time, which makes it easier to keep up alongside everyday life. The dose and the interval are proposed by a doctor after examining you.
