NAD+ safety, side effects and monitoring
NAD+ is a coenzyme present in every living cell, central to mitochondrial energy production and to the activity of sirtuins and PARP enzymes involved in DNA repair. It is sold by longevity and wellness clinics as an intravenous infusion, a subcutaneous injection and an oral or sublingual supplement, marketed for energy, cognition, addiction recovery and anti-ageing.
Safety profile
Infusion-site reactions, flushing, nausea, chest tightness and headache are commonly reported, and are usually related to infusion rate. The bigger issue is unknown long-term safety: NAD+ affects fundamental cellular pathways including DNA repair, and there is a theoretical concern — not a demonstrated one — about effects on cell proliferation. Anyone with a cancer history should discuss this with an oncologist before starting.
Monitoring
A legitimate programme establishes a baseline before it ships anything. For NAD+, ask what will be measured before you start, at what interval it will be re-measured, and what result would indicate the treatment is not working — a provider who cannot answer the last question has no plan for stopping.
Questions to ask
- Is the NAD+ compounded, and by which state-licensed pharmacy?
- What is the concentration and total dose per infusion?
- What specific outcome are we targeting, and how will we measure it?
- What is the evidence for that outcome in humans, not mice?
- What is the total cost including infusion time and follow-up?
Questions to ask about the pharmacy
The pharmacy matters more than the telehealth brand on the front of the website. The telehealth company arranges the consultation; the pharmacy makes the medicine you inject.
- Which specific pharmacy will fill my prescription? Not "our network" — the name of the facility.
- Is it a 503A state-licensed pharmacy or a 503B FDA-registered outsourcing facility? These are different regulatory categories with different oversight, and a company can use both for different products.
- In which state is it licensed, and can I look up the licence? State boards of pharmacy publish licensee databases.
- What is the exact salt form and concentration? Semaglutide sodium and semaglutide acetate are not the same active ingredient as the semaglutide base in approved products, and the FDA has said they are not appropriate for compounding.
- Is the vial single-dose or multi-dose? A multi-dose vial requires you to measure each dose yourself, which is the most common source of the dosing errors behind reported adverse events.
- Will you provide a certificate of analysis?
- Has the pharmacy received any FDA warning letter or state board action?
A provider that answers all seven in writing is demonstrating something real. A provider that will not name its pharmacy has given you an answer, whether it intended to or not.
Frequently asked questions
What does NAD+ cost through telehealth?
We have not verified a price and will not publish one we cannot substantiate. This page gives you the method to evaluate any quote you are given.
Is NAD+ FDA-approved?
NAD+ is not FDA-approved for any of the uses it is commonly marketed for. Injectable and intravenous NAD+ preparations are compounded products, which the FDA does not review for safety, effectiveness or quality before marketing. Oral NAD+ precursors such as nicotinamide ri
Does NAD+ work?
The honest summary: the biology is real and the clinical evidence is thin. NAD+ levels do decline with age, and that decline is genuinely implicated in mitochondrial dysfunction — this is well-established cell biology. What has not been established is that supplemen

The numbers behind this page
Three questions to ask before acting on this page
Every price quoted in this page comes from the programme's own pricing page and carries the date it was captured.
Ask in writing, before enrolling anywhere. Is the quoted figure the month-to-month rate, or does it require a prepaid term? Does it include every mandatory recurring fee, or is a membership billed separately? And which pharmacy fills the prescription — a 503A compounding pharmacy or a 503B outsourcing facility, and is it licensed to ship to your state?
A programme answering all three plainly has given you what you need to verify it without us. One answering none has also told you something. Neither outcome requires trusting a comparison site.
Reading the price against the market
What a longer horizon costs
The figures in this page sit inside a market with a measurable shape, and that shape is what makes any single price readable.
At the cheapest verified semaglutide rate of $119 a month (NexLife, 12-month plan), medication alone runs $1,428 a year, $4,284 over three and $7,140 over five. At the dearest, $299 a month, the same horizons are $3,588, $10,764 and $17,940.
Those are the numbers worth weighing, because the withdrawal evidence for this drug class is consistent: weight returns when treatment stops. The relevant question is what a sustainable course costs, not what a first year costs.
A programme you can afford for five years is a better clinical bet than one you can afford for eight months at a lower rate. Discontinuation is the expensive outcome here, and price is only one of the reasons people discontinue — tolerability, supply interruption and administrative friction account for the rest.

Questions this page answers
What is the cheapest verified GLP-1 programme?
NexLife at $119 a month for semaglutide and $139 for tirzepatide on its 12-month plan, both at standard therapeutic dosing and first-party verified September 4, 2026. Month-to-month, NexLife is $139 and $169; Oak Longevity ($133, flat, no membership) is the next-cheapest semaglutide programme.
Are compounded GLP-1 medicines FDA-approved?
No. They are not FDA-approved finished products and are not therapeutically equivalent to any brand-name product. FDA does not review them for safety, effectiveness or manufacturing quality before marketing.
Why do the same programmes quote two different prices?
Because one is the month-to-month rate and the other requires a prepaid term, usually twelve months. We rank on the month-to-month figure and state the prepaid rate separately, since a rate requiring a year's commitment is not the same offer.
Where do these prices come from?
Each is read from the programme's own published pricing page and carries its capture date. The full set of 24 standard-dose records is at /api/prices.json with molecule and dose class on every record.
