Short answer
NAD+ is a coenzyme involved in cellular energy metabolism, and research shows levels fall with age. An NAD+ infusion delivers it directly into a vein and is commonly chosen for energy, fatigue, and healthy-aging maintenance. In Japan it is self-pay care done in one day, but it must be infused slowly, usually for an hour or more.
01
What an NAD+ infusion is
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme cells need to produce energy, and it is also involved in processes such as DNA repair. Research shows NAD+ levels decline with age.
An NAD+ infusion delivers NAD+ directly into a vein. Some clinics use NMN, a precursor of NAD+, such as the NAD+ β-NMN infusion at Ginza YR Clinic. Unlike oral supplements, an infusion bypasses digestion.
Worth knowing: clinical research on NAD+ infusions in humans is still building and results vary. It is best considered a maintenance option rather than treatment for a disease.

Frequently asked questions
What is the difference between NAD+ and NMN?
NMN is a building block (precursor) the body uses to make NAD+. An NAD+ infusion supplies NAD+ directly; an NMN infusion supplies the precursor for the body to convert. The physician advises which suits you.
Infusion or oral supplements?
An infusion goes straight into the blood without digestion; oral supplements are easier and cheaper. Research comparing long-term effects in humans is limited.
Are there side effects?
If infused too quickly, chest tightness, nausea, flushing, or headache can occur, usually easing when the rate is slowed. Tell the physician about any conditions or medications.
How often should I have it?
There is no single standard; the physician advises based on your goal and health.
