Most clinic pages give the same plan for NAD+ drips: a loading phase of four to ten drips over two to four weeks, then one drip a month after that. At Las Vegas Mobile IV Therapy, four 250 mg drips come to $1,400 before the first monthly visit.
Where the loading-then-monthly schedule comes from
Clinics use two terms for the plan, and both describe how NAD+ drips are sold. A loading phase is a run of drips booked close together at the start. Maintenance is a single drip repeated every few weeks after that, most often monthly.
The research on NAD+ drips is small. Every human study of NAD+ drips that a 2026 review in Frontiers in Aging describes used either a single infusion or drips on consecutive days. One gave 1,000 mg a day for six days to eight adults aged 70 to 80. None of them spaced drips a week or a month apart.
One study took its four-day course straight from commercial practice. In a 2026 chart study, researchers at a clinic chain reviewed the records of six clients who had 500 mg of NAD+ on four days in a row. They described that course as the typical commercial loading dose recommended by the compounding pharmacy. They followed those clients for 30 days and wrote that more studies are needed on dosage and on effectiveness beyond that point. The authors worked for the chain that gave the drips, and they name that as a possible source of bias.
Comparing schedules would mean measuring an outcome, and a 2026 systematic review in Ageing Research Reviews found no outcome trial of NAD+ given by drip or injection for aging or general wellness.
That leaves no tested schedule to follow. Here, each NAD+ drip starts with a health check: the clinician takes your vitals and reviews your medical history, medications and allergies. Each drip has medical oversight by our Medical Director, Dr. Daniel Olivero, MD.
How many NAD+ drips do you need?
Nobody can give you a number with evidence behind it. The studies that gave several drips gave a fixed course of four or six, and none of them tested whether that many did more than a single drip would have.
Each NAD+ drip here is priced and booked as a single treatment, so having one doesn't commit you to a second. Whether you book more, and how many, is up to you.
What a series costs at $100 a visit plus $1 a milligram
Every NAD+ drip here is priced the same way: a $100 base for the visit plus $1 for each milligram of NAD+ in the bag. You choose the dose. A 250 mg drip is $350, and a 500 mg drip is $600. If you've seen this drip listed at $100 a session, that's the base charge, not the price of a drip.
| Pattern | Drips | At 250 mg | At 500 mg |
|---|---|---|---|
| One drip | 1 | $350 | $600 |
| A four-drip series | 4 | $1,400 | $2,400 |
| One drip a month for a year | 12 | $4,200 | $7,200 |
The base charge makes small, frequent drips the most expensive way to buy the same number of milligrams. Two 250 mg drips cost $700, while one 500 mg drip costs $600, because the second visit carries its own $100 base.
Any drip between 8 PM and 7 AM also carries a $99 after-hours fee, so a four-drip series booked for late evenings adds $396. Each booking takes a $50 deposit, which comes off that drip's total rather than adding to it.
How long does an NAD+ IV session take?
An NAD+ drip is a 90-minute treatment, and the booking system reserves a 135-minute slot for it. Your clinician usually arrives 45 to 60 minutes after you book, and up to 90 at busy times such as convention weeks. If you book for the next available visit, plan on two and a quarter to two and a half hours from booking to the end of the treatment on an ordinary day.
Four drips mean six hours with a clinician, spread across four visits.
Deciding how often to get the next one
With no schedule to copy, the useful questions are about the drip you just had and the one you're considering. Four things should shape the next booking.
- How the last one went. NAD+ drips can bring on symptoms while they run, and in the chart study people slowed their drips to cope. If yours was hard to get through, that is a reason to leave more time before the next one.
- The cost, in money and in time. A drip a month at 250 mg comes to $4,200 and 18 hours with a clinician over a year.
- Anything new since your last drip. A new medication, a new diagnosis or a pregnancy is worth raising at the health check before the next one.
- Whether a drip is the right format for you. NAD+ is also given here as an injection. If sitting through a drip is the hard part, read our comparison of a drip or injection for NAD+ before you book another.
