NAD+ Injection Dosage: How Providers Set Your Dose

By TelosRX Editorial Team October 08, 2026

There is no FDA-approved NAD dosage for injections, because compounded NAD+ is not an FDA-approved drug. Your dose and schedule are set by a licensed provider based on your health history, goals, tolerance and route, then adjusted over time. Numbers you see online are not instructions.

Search "nad dosage" and you will find a dozen different answers. Different amounts, different schedules, different routes. Most of them sound sure of themselves.

That confusion is the point of this guide. We won't hand you a number. We'll show you how a provider actually decides one, and what changes it once you start.

Why there is no standard NAD dosage

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell. It helps turn food into usable energy and feeds enzymes involved in DNA repair, such as sirtuins and PARPs. It is not a peptide, a vitamin or a hormone.

Research suggests NAD+ levels decline with age in tissues of rodents and humans, according to a 2021 review in Nature Reviews Molecular Cell Biology. That finding drives much of the interest in replacing it. New to the basics? Start with our guide to NAD+ injections.

Here is the part that matters for dosing. Compounded NAD+ is not FDA-approved. It has not been evaluated by the FDA for safety, effectiveness or quality. FDA-approved drugs come with a label that lists a tested dose. Compounded NAD+ has no such label to point to.

Human evidence for subcutaneous NAD+ is also limited. Most published human data come from IV infusions or oral precursors like NR and NMN. That leaves providers working from clinical judgment, pharmacy guidance and how you respond, not from one official chart.

Why the NAD+ doses you see online vary so much

Forums, clinic menus and influencer videos list wildly different nad plus injection amounts. A few reasons explain the spread:

  • Different routes. IV drips, intramuscular shots, subcutaneous shots and nasal sprays behave differently. A number from one route doesn't carry over to another.
  • Different concentrations. Compounded vials vary in strength, so the same volume can hold different amounts.
  • Different goals and people. A protocol written for one person's history may be wrong for yours.
  • Different sources. Some products sold online are labelled "research use only" and come with no medical oversight at all.

So treat any number you read as context, not a plan. Only the dose on your prescription and pharmacy label applies to you.

How a provider sets your NAD+ injection dose

At telos rx, a licensed provider reviews your online intake and decides whether NAD+ fits you, then which route and plan. These are the main inputs:

Factor What the provider looks at Why it matters
Health history Conditions, medications, pregnancy, past reactions Rules NAD+ in or out, and shapes caution
Your goals What you hope NAD+ supports Guides the overall plan
Tolerance How you feel after early doses Drives adjustments up, down or sideways
Route Subcutaneous injection or nasal spray Each route has its own dosing logic
Labs Results from periodic lab work Adds objective data to how you feel
Preference Comfort with needles, routine, lifestyle A plan you can stick with is a better plan

The pharmacy label then spells out the exact amount, how to prepare it and how to store it. If the label and your instructions ever disagree, stop and message your care team.

Why providers often start low

In general clinical practice, many providers begin new therapies at a conservative dose and adjust from there. With NAD+ injections, that approach gives your body time to settle and gives your provider a clear read on how you respond.

This is a common approach, not a promise of a specific schedule. Your provider may choose a different path based on your history.

What can change your NAD+ plan

A dose isn't fixed on day one. Providers revisit it when something shifts. Common triggers include:

  1. Side effects. Reported injection reactions include redness, soreness or swelling at the site, flushing, nausea, headache, fatigue and lightheadedness. Tell your care team about any of them. Our NAD+ injection side effects guide covers what to watch for.
  2. Lab results. New lab data can prompt your provider to keep, adjust or pause your plan.
  3. A route change. Switching between injection and nasal spray means a new set of instructions, not a conversion you work out yourself.
  4. Health changes. New medications, a new diagnosis or pregnancy all need a fresh review.
  5. How it fits your life. If a schedule isn't workable, your provider can look at alternatives.

One rule holds through all of it: never raise, lower or skip doses on your own. Message your provider first.

Seek urgent care for hives, swelling of the face or throat, chest pain or trouble breathing.

Subcutaneous vs nasal NAD+ dosing: how they differ

A nad subcutaneous injection places NAD+ into the fat layer just under the skin, usually the abdomen or thigh, with a short, fine needle. A nasal spray delivers it through the lining of the nose, no needle involved.

Because the routes are so different, their doses are not interchangeable. Your provider sets each one separately. Here is the conceptual difference:

Subcutaneous injection Nasal spray
How it's measured A volume drawn into a syringe A number of sprays
Needle Yes, short and fine No
Human evidence Limited Limited
Who sets the dose Your licensed provider Your licensed provider

Curious about the injection itself? Read NAD+ subcutaneous injection, explained. Leaning toward needle-free? Our NAD+ nasal spray dosage guide covers that route.

telos rx offers both forms, and your provider helps you choose. You can compare them on the NAD+ product page.

What the evidence on injected NAD+ actually shows

It's worth being honest about the science. One of the few human studies of directly infused NAD+ was small: eight men received a slow IV infusion over 6 hours, alongside a saline control group.

The researchers found that, at that infusion rate, NAD+ was rapidly removed from the blood for at least the first 2 hours, with no adverse events observed. You can read the 2019 pilot study in Frontiers in Aging Neuroscience.

That was IV, not subcutaneous, and it wasn't designed to find a dose. It shows how early the human research still is. It's one more reason NAD+ injections belong under a provider's care rather than a copy-pasted protocol.

Frequently asked questions

What is the standard NAD+ injection dosage?

There isn't one. Compounded NAD+ is not FDA-approved, so there is no official labelled dose. A licensed provider sets your dose and schedule based on your health history, goals, tolerance and route, and adjusts it over time.

Why do NAD+ doses online vary so much?

Online numbers mix different routes, vial strengths, goals and sources, including products sold for research use only. None of them is tailored to you. Only the dose on your prescription and pharmacy label applies.

Do providers start NAD+ injections at a low dose?

Many providers start new therapies conservatively and adjust based on how you respond. That is a general clinical approach, not a fixed rule. Your provider decides what fits your history.

Can I change my NAD+ dose myself?

No. Don't raise, lower or skip doses on your own. Message your care team first so your provider can review side effects, labs or other changes and update your plan safely.

Is nasal spray dosing the same as injection dosing?

No. The routes deliver NAD+ differently, so doses are not interchangeable. Your provider sets each route's dose separately, and a switch comes with new instructions.

How do I get an NAD+ dose set by a provider?

Complete a short online visit with telos rx. A licensed provider reviews it asynchronously. Every prescription is subject to medical approval by a licensed provider, and you pay nothing if you're not approved.
