NAD+ Therapy
A coenzyme central to cellular energy, infused slowly and dosed to where you are starting from.
NAD+ is a coenzyme every cell uses in the reactions that convert nutrients into usable energy, and its availability declines with age. Supplementing it intravenously is used to support cellular energy, mental clarity and recovery. The practical point most clinics understate is that NAD+ must be infused slowly: given too quickly it produces chest tightness, cramping and nausea, so the rate is set for comfort and the appointments are long. A 500 mg infusion needs about three hours and 1,000 mg around five. Most patients start at 100 mg to see how they tolerate it, then move to 250 mg, which is the dose the standard five-session course is built on. An intramuscular injection is a faster way to trial NAD+ or to maintain between infusions, and 100 mg can be added to any other drip.

Common questions
Why does an NAD+ infusion take so long?
Infused too quickly, NAD+ commonly causes chest tightness, cramping and nausea. The rate is set for your comfort, so a 500 mg infusion takes around three hours and 1,000 mg around five. Bring something to occupy you.
What dose should I start at?
Most first-time patients start at 100 mg to see how they tolerate it. The 250 mg dose is the usual therapeutic starting point and the one the five-session course is built on.
Is the injection as good as the infusion?
The intramuscular shot is a faster and lower-cost way to trial NAD+ or to maintain between infusions. It does not deliver what a full infusion does.
