There is no universal NAD+ dosage, because NAD+ is not an FDA-approved drug with an approved label, so no official dosing schedule exists to cite. With compounded NAD+ nasal spray at telos rx, a licensed provider sets and adjusts the amount.
Search nad dosage and you get charts: milligram tables, spray counts, protocols laid out with the confidence of a package insert. Almost none of it traces back to a regulatory label, because no such label exists.
Why There Is No Standard NAD+ Dose
Approved medications carry a dosing schedule because a manufacturer ran trials in a defined population and the FDA reviewed the data. That process produces a label, and the label is what a prescriber works from.
Compounded NAD+ has been through no such process. It is not FDA-approved, and it is not approved for anti-aging, longevity, energy, or any other wellness indication. The FDA states plainly that compounded drugs are not FDA-approved, and that it does not verify their safety, effectiveness or quality before marketing.
Compounded medicines are prepared by licensed US compounding pharmacies against a prescription written for one individual. The amount is a clinical judgement made by that prescriber, not a figure copied from an approved schedule.
Why IV Figures Do Not Translate to a Nasal Spray
Most numbers circulating under nad dosing originate in IV clinic material, and the quantity in an infusion bag says very little about an intranasal spray.
Route changes what reaches circulation and how much survives the trip. NAD+ is a large, charged molecule with poor oral bioavailability that is substantially broken down in the gastrointestinal tract, which is why precursor supplements and non-oral routes exist at all. Intranasal delivery crosses the nasal mucosa and bypasses first-pass hepatic metabolism, though absorption there is limited for large water-loving molecules, and published human evidence specifically for intranasal NAD+ remains limited and preliminary.
| Route | What a quoted figure describes | Why it does not transfer |
|---|---|---|
| IV infusion | Amount and rate delivered into the bloodstream in a clinic | Skips every absorption barrier, so it reflects delivery, not what another route achieves |
| Oral supplement | Amount of a precursor swallowed, usually NMN or NR rather than NAD+ itself | Different molecule, different pathway, heavy losses before absorption |
| Intranasal spray | Amount presented to the nasal mucosa in a metered actuation | Uptake depends on formulation, concentration and mucosal factors that differ by product |
A figure from one row tells you almost nothing about another. Route-by-route detail sits in nasal spray vs IV therapy, vs injections and vs oral supplements.
What the Research Numbers Actually Describe
Real figures do exist in the literature, and they are worth reading correctly rather than lifting. A 2017 open-label study followed eight healthy volunteers taking oral nicotinamide riboside, a precursor rather than NAD+ itself, titrating up to 1000 mg twice daily, with whole blood NAD+ roughly doubling at steady state. That is where the nad 1000 mg figure comes from: eight volunteers, a supplement, an oral route, no control group. It was never intended as guidance.
On the IV side, a 2019 pilot study infused NAD+ for six hours at a fixed rate and reported no measurable change in plasma NAD+ for the first two hours. The authors called it the first data of its kind in a human cohort. Even for the oldest route, the basic pharmacokinetics were mapped recently, in very small numbers.
Neither figure is a recommendation, and neither was generated in an intranasal population.
A dosing decision that accounts for your health history, your current medications and how you actually respond is not something a chart can produce. A licensed provider can.
See NAD+ nasal spray at telos rxWhat a Provider Weighs
With no label to defer to, the decision rests on the individual patient.
- Health history. Existing conditions, particularly anything involving the liver, kidneys or cardiovascular system, change what is appropriate and whether NAD+ is suitable at all.
- Current medications and supplements. Including precursor products already being taken, which people forget to declare because supplements do not feel like medication.
- Prior exposure and tolerance. Someone who has had infusions and tolerated them poorly is a different case from someone with none.
- What the person is trying to address. Stated goals shape whether this medication is a reasonable fit, and sometimes it is not.
- Reported response over time. The first amount prescribed is a starting point to be revisited, not a permanent setting.
Approval is never automatic. Everything here is subject to medical approval by a licensed provider, who may decline or suggest another direction.
Why Titration and Reassessment Exist
Titration means starting at a conservative amount and adjusting on the basis of what gets reported back. It is ordinary practice wherever individual response varies and no label exists to fall back on.
Two reasons it applies here. Tolerability is individual, so starting low limits how much of an unpleasant reaction someone sits through before an adjustment. And the evidence for intranasal NAD+ does not support presenting one fixed amount as correct for everybody.
Reassessment is the other half. A prescription is a working hypothesis about what suits a person, revised as information arrives. Reactions worth reporting are covered in NAD+ side effects.
What Monitoring Looks Like
Monitoring is what makes adjustment possible. At telos rx that means unlimited care-team messaging, quarterly labs, and dose adjustments handled through the same asynchronous channel.
You report what you are experiencing, the provider reads it against your history and labs, and the plan holds or changes. Nothing in that loop promises a particular experience or attaches a timeframe to one.
Why Not to Follow a Dosing Chart You Found Online
Do not take dosing instructions from a forum thread, a supplement retailer, or a nad dosing chart published by a site that cannot see your medical history. Those sources know nothing about your conditions, medications or tolerance.
Two traps recur. Charts mix routes, putting an IV figure and an oral supplement figure in one table as though they were interchangeable. And charts for NMN or NR are not charts for NAD+, because those are different molecules on a different pathway, as in NAD+ vs NMN and NMN vs NR.
One correction while it is here: NAD+ is a coenzyme, not a peptide, however often it gets searched that way. Why that matters is in is NAD a peptide; the basics are in what is NAD+.
How the Evaluation Works at telos rx
telos rx is an online-first, asynchronous telehealth service. You complete a written intake covering health history, current medications and what you are hoping to address. A licensed provider reviews it and responds in writing, with no appointment to book.

Frequently Asked Questions
What is the correct NAD+ dosage?
There is no single correct NAD+ dosage. NAD+ is not an FDA-approved product, so there is no approved label and no official dosing schedule to follow. For compounded NAD+, the amount is set by the prescribing provider for one individual, based on health history, current medications and reported response.
How much NAD should I take?
That is a question for a licensed provider who has reviewed your health history, not one an article can answer responsibly. Any figure published without knowing your conditions, medications and tolerance is guesswork. At telos rx the amount is set through a written intake, and approval is not guaranteed.
Is there an NAD dosing chart I can follow?
No chart found online should be treated as instruction. Most mix delivery routes, presenting IV, oral and intranasal figures as though they were interchangeable, and many describe precursor supplements such as NMN or NR rather than NAD+ itself. Dosing decisions belong with a prescribing provider.
Does the 1000 mg figure apply to NAD+ nasal spray?
No. The 1000 mg figure in circulation comes from a small open-label pharmacokinetic study of oral nicotinamide riboside, a precursor rather than NAD+, in eight healthy volunteers. It is not guidance, and it does not transfer to an intranasal compounded product.
How many sprays a day is NAD+ nasal spray?
The number of sprays is specified by the prescribing provider, and this article does not publish one. telos rx describes the product as a daily at-home format with personalized dosing guidance from your provider. Follow your prescription rather than an article.
Can my NAD dose be changed after I start?
Yes, and that is the expected pattern. Titration exists because individual response varies and no population-level label exists for compounded NAD+. At telos rx, unlimited care-team messaging and quarterly labs are included, and dose adjustments run through the same asynchronous channel. Any change is made by a licensed provider.
TelosRX is LegitScript-certified. Compounded medications are not FDA-approved and are prepared under federal compounding regulations.
