Social media feeds over the last couple of years have persistently been selling the idea that fatigue is cured by a shot and aging is delayed by an IV drip.
At the center of this wave sits NAD+, a coenzyme with an impressive reputation and a much more modest evidence base. Below, we break down what is reliably known about it and what still remains a promise for now.
The Molecule Without Which the Cell Does Not Function
All living cells have NAD+, which plays a role in energy production, DNA repair, and cell survival. It’s a statement by the National Institutes of Health, not an ad brochure.
The level of the coenzyme does decrease as we get older, and that very information has been the basis of a whole industry of supplements and injections.
Hence, the demand for NAD+ injections, which in the US are dispensed strictly by prescription. Telehealth services like Helimeds have built a dedicated route for this: an online questionnaire, review of answers by a licensed doctor, shipping from a pharmacy to a home address. I
ntravenous administration without a prescription is illegal, and the New York prosecutor’s office recently brought this up right in the courtroom.
Why a Shot and Not a Capsule
The sellers’ logic seems sound: an injection doesn’t go through the digestive tract and into the bloodstream. There is significant absorption of oral forms, and a fight with that is hard to win. The problem isn’t there, though: only because something enters the blood does it automatically have the desired effect. It is still different from bioavailability and benefit.
The majority of the in-depth studies have focused on the NAD+ precursors nicotinamide riboside and nicotinamide mononucleotide (NMN), rather than NAD+.
This distinction matters because evidence for NAD+ precursors cannot automatically be applied to injectable NAD+ itself. There is limited human data on the use of injectable NAD+ and limited, inconclusive data for use in humans. That is, the mechanism is understood, but the clinical effect is not so.
What the Regulator Thinks About It
This is the part that spells discomfort. NAD+ has not been approved by the FDA as a medication and was not listed in the final 503A Bulks List in 2017, when the Pharmacy Compounding Advisory Committee (PCAC) voted against placing the substance on the list due to its instability and the absence of literature to assess safety. The FDA has been looking to remove NAD from the list since 2019 and has not done so.
Injectable NAD+, therefore, exists only as a compounded drug. Formulations like “meets strict FDA manufacturing standards,” which appear on sellers’ websites, should be viewed critically, since the drug lacks approval.
Before buying, it makes sense to clarify several things:
- License and registration of the pharmacy preparing the formula;
- Presence of testing protocols for every batch for sterility and endotoxins;
- Who exactly issues the prescription and whether that doctor is available for contact;
- What is included in the price and whether auto-renewal is enabled.
How the Offer Looks in Practice
Terms across different telehealth services vary more than might be assumed from identical ad banners. Helimeds, for example, reveals its program parameters directly on the drug page.
| Program detail | What Helimeds states |
| Price | $99 per month with the first 12-month order |
| Billing | One-time charge, no recurring subscription |
| Shipment frequency | Monthly or once every 12 weeks, depending on the plan |
| Consultation | Free, fully online, text-based |
| Insurance | Not required |
| Lot testing | Sterility, potency, endotoxins |
The last line deserves separate attention. Endotoxins stand on this list for a reason: the FDA has already issued warnings about contamination risks of sterile NAD+ preparations, and one product recall was classified under Class I recall status.
Considering this, documentation from a pharmacy stops being bureaucracy and becomes basic selection hygiene. Requesting it is worth doing before payment, not after the first injection.
The Cost of Inattention
Elizabeth Baron passed away about an hour after being given an infusion of NAD+ at Bereshit Lifestyle Center in July 2026 in the Bronx. The injection was given by Luis Rojas Cabrera, who was not a licensed physician, and was charged with reckless endangerment and unauthorized practice.
A medical examiner was still determining the cause of death at the time it was reported, and there was no direct connection to the drug yet.
The case speaks not so much about the substance itself as about the environment around it. A prescription, a license, and a documented batch are three things distinguishing a medical procedure from a risky service in a room with dimmed lights. None of them are visible in a photo in a promotional post.
Final Take
NAD+ is a real and important molecule, whereas injectable therapy surrounding it currently runs noticeably ahead of the evidence.
The adult approach consists of separating biochemistry from ad promises and verifying licenses prior to purchase, not after it. Therefore, interest in the topic of longevity is completely justified, while advanced trust is not.
