NAD+ therapy, start to finish: injections, IV, precursors and safety

Everything our nurses have written about NAD+, organized so you can go straight to the answer you need — how injections compare with a drip, where NR and NRH fit, what side effects are normal, and how often to repeat a session.

NAD+ injections

Start here if you want the 10-minute maintenance option: what an injection is, how it feels, and how often to repeat it.

NAD+ injections vs IV infusions

Dose, absorption, chair time and cost differ a lot between an IM shot and a 250mg drip. These guides compare them side by side.

Precursors: NR, NRH and NMN

NAD+ isn't the only way to raise cellular NAD. Nicotinamide riboside (Niagen), its reduced form NRH, and NMN all sit upstream — with very different evidence and legal status in the U.S.

Safety, side effects and screening

Flushing, chest tightness and nausea during a drip are dose-rate effects, not allergies. These posts cover what's normal, what isn't, and who we screen out.

Protocols and timing

How often, at what time of day, and when to switch from a loading phase to maintenance.

FAQ

NAD+ therapy FAQs

Are NAD+ injections as effective as an IV drip?

An IV delivers a much larger dose with full bioavailability, so it produces the biggest and fastest change in cellular NAD+. Injections deliver a smaller dose in about ten minutes, which makes them a practical way to hold your levels between infusions. Most clients load with IV, then maintain with injections.

What is NRH and is it available in the U.S.?

NRH is the reduced form of nicotinamide riboside. It raises NAD+ faster than NR in laboratory and animal work, but it is not an FDA-approved or clinically available injectable in the U.S., so we do not offer it. The precursor we do infuse is nicotinamide riboside (Niagen).

How often should I get NAD+?

A common protocol is a loading phase of 4–10 infusions over 2–4 weeks, then monthly maintenance with optional weekly injections. Your nurse and our medical director set the schedule based on your goals and how you respond.

Is NAD+ therapy safe?

NAD+ has a strong safety profile when it is administered by licensed clinicians. The common effects — warmth, flushing, chest or abdominal tightness, mild nausea — are tied to infusion speed and resolve within seconds to minutes when we slow the drip. Serious reactions are rare.

Who should not get NAD+ therapy?

We screen for pregnancy and breastfeeding, active cancer treatment, significant kidney or liver disease, and certain cardiac conditions. Your consult with our nurse practitioner determines whether NAD+ is appropriate for you.

Do oral NAD+ supplements work as well?

Oral NR and NMN capsules raise precursor levels modestly, but first-pass liver metabolism limits how much reaches your cells. IV and injectable routes bypass digestion, which is why the clinical effect is larger and faster.
