NAD Injection Dosage Chart

NAD injection dosing varies based on treatment goals, individual tolerance, and provider protocol. Most physician-guided programs structure dosing in milligram ranges, starting conservatively before adjusting based on patient response. If you're new to NAD therapy, review our What is NAD guide before exploring specific dosing levels. This dosage chart provides a general overview of common dosage tiers, frequency schedules, and treatment phases used in clinical programs. For a full breakdown of how dosing connects to treatment scheduling, see our NAD injection frequency guide. Before starting any program, understanding where to inject NAD is an equally important part of your administration preparation. Understanding how long results from each dosing phase typically last is also essential when planning a structured program — see our guide on how long NAD injections last for a phase-by-phase breakdown. Patients using NAD specifically for fatigue and energy will find tailored dosing recommendations in our NAD injections for energy guide. For longevity-focused protocols and structured aging support, explore our NAD injections for anti aging guide to see how milligram tiers align with anti-aging programs.

How NAD Injection Dosage Is Structured

NAD injection dosage is typically measured in milligrams per session and structured within a clinician-guided treatment protocol. Because NAD+ therapy requires medical oversight, dosing strength is determined through evaluation by a licensed healthcare provider rather than personal preference. In most cases, patients must first receive a NAD injection prescription after completing a medical screening that reviews health history, treatment goals, and individual tolerance before establishing an appropriate starting dose.

Most programs begin with a conservative dose to evaluate how the body responds before increasing milligram strength. This gradual approach helps minimize potential NAD injection side effects while allowing providers to identify the most effective dosing range for each individual. Dosage adjustments are made based on energy response, tolerance feedback, and overall treatment objectives. Patients who want to understand what clinical standards define a properly supervised program should also review our are NAD injections safe guide before starting treatment.

Injection strength and frequency are closely connected. A higher milligram dose may require longer spacing between sessions, while lower doses are often administered more frequently during early treatment phases. To understand how dosing phases and titration schedules are organized from start to finish, review our NAD injection protocol guide.

  • Dosing is determined by clinician evaluation, not self-directed
  • Strength and frequency are adjusted together based on individual response

What Affects NAD Injection Dosage?

Treatment Goals

The purpose of NAD therapy influences starting dosage. Individuals focused on energy support or metabolic wellness may begin at different milligram ranges than those following intensive longevity protocols. Providers align dosage strength with individual health objectives.

Body Response & Tolerance

Each patient responds differently to NAD+ injections. Factors such as metabolism, hydration, and overall health can influence how the body tolerates dosage increases. Providers monitor response and adjust milligram strength accordingly over time.

Cellular Repair & Aging

Licensed clinicians establish structured NAD injection dosing protocols based on medical intake, health history, and pharmacy-compounded formulation standards. Treatment strength is not self-directed — ongoing clinical oversight helps ensure dosage remains appropriate and adjusted when necessary.

NAD Injection Dosage Chart Goals

The following NAD injection dosage chart outlines common milligram ranges and frequency schedules used in physician-guided programs. These ranges are general reference points — actual dosing is always determined by a licensed provider based on individual health evaluation. For cost implications of different dosage tiers, see our NAD injection cost breakdown.

Starting & Low Dose
(100–250 mg)

Most programs begin at 100–250 mg per session to evaluate individual tolerance. This conservative range allows providers to monitor response before increasing strength. Starting doses are typically administered 2–3 times per week during the initial treatment phase.

Standard Dose (500 mg)

500 mg is the most commonly used dosage tier in physician-guided NAD injection programs. This range is typically used for energy support, metabolic health, and cognitive wellness goals. Sessions are generally scheduled 1–2 times per week at this strength.

High Dose & Maintenance
(1000 mg / 100–500 mg)

Higher dose protocols of 1000 mg are sometimes used in longevity-focused programs, typically spaced weekly. After initial treatment phases, providers often transition patients to a maintenance range of 100–500 mg for ongoing support.

Frequently Asked Questions About
NAD Injection Dosage Chart

An NAD injection dosage chart outlines common milligram ranges, frequency schedules, and treatment phases used in physician-guided NAD+ programs. Most charts break dosing into starting, standard, high dose, and maintenance tiers to help patients understand how programs are structured.

Most NAD injection dosage charts reference ranges between 100–1000 mg per session. Starting doses typically fall between 100–250 mg, standard doses around 500 mg, and intensive protocols up to 1000 mg. Maintenance phases often return to lower milligram ranges administered less frequently.

Yes. An NAD injection dosage chart reflects multiple treatment phases — loading, standard, and maintenance. Providers adjust milligram strength and frequency based on patient response, tolerance, and long-term wellness goals.

On a standard NAD injection dosage chart, 500 mg represents the most common clinical dose for energy and metabolic support. 1000 mg is typically reserved for intensive longevity protocols and is usually spaced further apart between sessions.

Frequency varies by dosage tier. Starting doses on an NAD injection dosage chart are typically administered 2–3 times per week, while maintenance doses are given biweekly or monthly. See our NAD injection frequency guide for full scheduling details.

No. While general NAD injection dosage chart ranges provide useful reference points, actual dosing is individualized by a licensed provider based on health history, treatment goals, and tolerance. A valid prescription is required for all NAD+ injection programs.
Start NAD Therapy with Medical Guidance
Before considering NAD therapy, speak with a licensed provider to determine whether NAD+ injections support your metabolic health objectives. Clinical oversight helps ensure dosing, frequency, and treatment plans are customized to your individual needs.
