NAD+ Dosage Calculator

Your NAD+ protocol, in clear numbers.

NAD+ dosing is personal. Tell us where you are and what you're after — we'll turn published subcutaneous reference ranges into a simple daily, weekly and monthly plan, and show you exactly how long your kit will last.

Shapes how we frame your plan. Your dose is set by the two steps below — the science supports the same subcutaneous range across goals.

The NAD+ dosage chart, in full

For transparency, here is the published subcutaneous, intramuscular and IV reference protocol our calculator is built on (based on a 100 mg/ml preparation). THE [NAD] SHOP is designed around the subcutaneous route — the gentlest, most at-home-friendly way to dose.

RouteStarting doseTypical / escalatedWeekly total
SubcutaneousOur method 30 mg (0.3 ml) daily, first week 50 mg (0.5 ml) Mon–Fri 210–250 mg
Intramuscular 50 mg (0.5 ml) Up to 3× per week Up to 150 mg
IV infusion 250 mg over ~2 hrs, weekly 500 mg over ~4 hrs, weekly 250–500 mg

Subcutaneous injection lets you spread NAD+ into small, comfortable doses at home — avoiding the flushing and clinic time of high-dose IV drips. That's why the At-Home Kit ships with a 31G 6mm micro-needle: short, fine, and made for self-administration.

NAD+ dosage questions, answered

The essentials people ask before their first injection.

How much NAD+ should I inject per day?
For subcutaneous NAD+, published pharmacy reference ranges start at 30 mg (0.3 ml) daily for the first week, then commonly move to 50 mg (0.5 ml) on weekdays (Monday–Friday), for roughly 210–250 mg per week. Your ideal dose depends on your health, goals and prescriber's guidance.
Why start with a lower dose in week one?
A gentle acclimation week lets your body get used to NAD+ and reduces the chance of transient effects like flushing, nausea or a racing sensation, which are more common when injecting too much too fast. It's the same "start low, go slow" principle clinics use.
How long does one At-Home Kit last?
The kit contains 1000 mg of pre-mixed NAD+ (two vials) and 20 micro-needles. On the standard 50 mg weekday protocol that's exactly 20 injections — about one month, with vials and needles running out together. On a gentle 30 mg daily rhythm the NAD+ stretches further, but you'll use needles faster, so a second pack of needles keeps you going.
Subcutaneous, intramuscular or IV — what's the difference?
Subcutaneous (into the fat just under the skin) is the at-home standard: small, comfortable doses spread across the week. Intramuscular delivers a slightly deeper shot a few times weekly. IV infusions push much larger single doses (250–500 mg) over hours in a clinic. THE [NAD] SHOP is built around the subcutaneous route so you can dose confidently at home.
Can I take more to get faster results?
More isn't better with NAD+ — higher single doses mainly increase side effects, not benefit. Consistency at a sensible dose is what supports steady NAD+ levels over time. Any change to your protocol should go through your healthcare provider.
Is this medical advice?
No. This calculator is an educational tool that reflects publicly available pharmacy reference ranges. It doesn't replace a consultation. Speak with a licensed healthcare provider before starting NAD+, especially if you're pregnant, breastfeeding, taking medication or managing a health condition.

Important safety information

The NAD+ Dosage Calculator is provided for educational and informational purposes only. It presents general reference ranges drawn from publicly available dosing guidance published by a licensed compounding pharmacy and does not constitute medical advice, diagnosis or a treatment recommendation.

NAD+ dosing is highly individual and varies with your age, weight, health status, medications and goals. Figures shown are illustrative starting points, not a prescription. Do not begin, stop or change any NAD+ protocol without first consulting a licensed healthcare provider who can assess your individual needs. Never exceed a dose recommended by your prescriber.

Always inject using sterile technique with a fresh micro-needle, dispose of needles in the sharps bin provided, and stop and seek medical attention if you experience an adverse reaction. Keep all products out of reach of children.
