What Is a NAD+ Injection? Uses, Dosing, and Cost Explained
By the Casper Meds RX team · Last updated August 2026
If you’ve been reading about NAD+, you’ve probably seen it described as everything from an energy booster to an anti-aging breakthrough. Set the marketing aside and it’s a well-defined molecule with a specific role in the body. Here’s a plain-English look at what a NAD+ injection is, how it’s given, what affects the cost, and why it’s dispensed only after a licensed-provider evaluation.
What NAD+ actually is
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme — a helper molecule your cells already make and use in everyday metabolic processes. It is not a peptide, a hormone, or a stimulant. Because it occurs naturally in the body, it is studied in a range of contexts, and interest in supplementing it has grown. What that means for any individual is a question for a licensed provider.
NAD+ injection vs. IV vs. oral
NAD+ is offered in a few forms that differ mainly in how it is delivered:
- Subcutaneous injection — a small injection under the skin, often used at home on a provider’s schedule.
- IV infusion — delivered into a vein in a clinic, usually over a longer session.
- Oral or sublingual — capsules or tablets, including NAD+ precursors such as NMN or NR.
Which form is appropriate, if any, is determined by your provider based on your individual profile.
What people use NAD+ for
NAD+ is an area of active research, and people are interested in it for a variety of reasons. Because it is not an FDA-approved drug and the evidence is still developing, Casper Meds RX does not make claims about what it will do for you. Any potential use or expectation should be discussed with a licensed provider who can weigh it against your health history.
How NAD+ injections are dosed
There is no one-size-fits-all dose. Protocols vary, and the right approach — amount, frequency, and duration — is decided by the prescribing provider. Administration should always follow the specific instructions provided with your prescription.
What affects the cost
The cost of a NAD+ injection program generally depends on:
- The form and concentration prescribed
- How often it is administered
- Provider evaluation and ongoing oversight
- The compounding pharmacy that prepares it
Because compounded medications are prepared per prescription, pricing is tied to your specific plan rather than a shelf product.
Side effects and precautions
Reported effects are most often related to administration — for example, injection-site reactions, flushing, or nausea, particularly when a dose is given too quickly. This is not a complete list. Discuss possible risks, your medical history, and any other medications or supplements with your provider, and seek medical advice if you experience any adverse reaction.

Prescriptions are prepared by U.S.-licensed 503A pharmacies, and Casper Meds RX is LegitScript certified. A prescription is not guaranteed, and NAD+ is not an FDA-approved drug.
