NAD⁺ is sold three very different ways — as an oral precursor pill, a prescription injection, and a clinic IV drip — at wildly different prices. Here’s how the options compare, and the part the marketing skips: the evidence ranking is roughly the inverse of the price ranking.

Before you pay: what the evidence says
NAD⁺ is a real, important molecule that declines with age, and the idea of restoring it is legitimate. But the form matters enormously. Oral precursors (nicotinamide riboside and NMN) reliably raise blood NAD⁺ in randomized trials — though whether that produces anti-aging outcomes is still unproven. IV and injectable NAD⁺ are compounded, not FDA-approved, and have essentially no controlled outcome trials, despite being the most expensive route. So the cheapest option (an oral NR/NMN capsule) has the strongest human data, and the priciest (an IV drip) has the weakest. Read the full picture in our NAD⁺ precursors evidence guide and our NAD⁺ IV therapy review.
How we judge providers
Evidence honesty — does the format have human data, or is it riding a mechanism story? Oral precursors earn more credit than unproven IV claims.
Transparency — clear pricing, disclosed formulation, and (for supplements) third-party lab testing rather than a black-box label.
Clinical oversight — for prescription injections and IVs, a licensed clinician who actually reviews your intake, not a rubber-stamp.
Value for the evidence — what you pay weighed against what the format can actually be shown to do.
Approved affiliate partners are shown first and labeled; the assessment is editorial and unchanged by commercial status. Pricing and availability change often — figures are from each provider’s own site at time of writing, so verify current details before signing up.
1Best value
Oak Longevity
A low-cost telehealth service whose longevity line includes NAD⁺ and glutathione alongside sermorelin, prescribed through an online intake and shipped to your door — bundled with free health coaching and no membership fee.
Best for
Low-cost telehealth NAD⁺ within a broader longevity stack
A fitness- and healthspan-oriented telehealth program offering NAD⁺ and sermorelin alongside its weight-management track, aimed at people pairing longevity protocols with strength training.
Best for
Pairing NAD⁺ with sermorelin and a strength-training focus
An inclusive, no-insurance telehealth service that offers NAD⁺ therapy alongside compounded GLP-1, hair-loss and sexual-health treatments, reviewed by licensed providers and shipped to your door.
Best for
No-insurance telehealth NAD⁺ from an all-in-one provider
A physician-led service that offers NAD⁺ protocols alongside its lab-guided weight-management programs, with clinician oversight and all-inclusive pricing rather than surprise add-ons.
Best for
Physician-supervised NAD⁺ under lab-guided oversight
The consumer brand of Niagen Bioscience (formerly ChromaDex), selling patented nicotinamide riboside (Niagen) in oral capsules and powder. It is the most clinically-researched NAD⁺ precursor on the market, and as an NR product it sidesteps the regulatory question hanging over NMN supplements.
Best for
The most clinically-studied oral NAD⁺ precursor (NR)
A longevity-supplement brand specializing in liposomal and sublingual delivery of NMN and NR, with publicly posted third-party lab certificates per batch and an unusually broad format range (powder, capsule, fast-dissolve tabs).
A telehealth provider that connects patients with U.S. physicians to obtain prescription NAD⁺ injections shipped home for self-administration, billed as a monthly plan that bundles the consult and supplies. Injectable NAD⁺ is compounded and not FDA-approved.
Best for
Prescription at-home NAD⁺ injections via telehealth
A mobile IV-therapy company that sends a nurse to your home or office to administer NAD⁺ infusions, sold per-session or via monthly membership tiers across 100+ cities. IV NAD⁺ is compounded, costly, and lacks controlled outcome trials.
A nationwide wellness-studio franchise (210+ locations) offering NAD⁺ IV drips and quick intramuscular NAD⁺ shots alongside cryotherapy and red-light services. Pricing and exact protocols are set per franchised studio, so quotes vary by location.
Best for
In-person NAD⁺ IV or IM shots at a national studio chain
It depends on the form and the claim. Oral NAD⁺ precursors (nicotinamide riboside and NMN) reliably raise blood NAD⁺ levels in randomized trials — but whether that translates into anti-aging or energy outcomes is still unproven. IV and injectable NAD⁺ are compounded, not FDA-approved, and have essentially no controlled outcome trials for wellness uses, despite being the most expensive option. Treat dramatic 'reverses aging' claims skeptically across every format.
Which form of NAD⁺ has the best evidence?
Oral precursors. Nicotinamide riboside (NR, as in Tru Niagen) is the most clinically-studied and reliably raises NAD⁺ in human trials. NMN raises NAD⁺ too but faces an unresolved FDA question about its supplement status. IV NAD⁺ delivers a large dose but is rapidly cleared and lacks outcome data; injections sit in between. The evidence ranking is roughly the inverse of the price ranking — the cheapest oral option has the strongest data.
Is IV NAD⁺ worth the cost?
From an evidence standpoint, the case is weak. IV NAD⁺ can run hundreds to thousands of dollars a month, yet there is no controlled outcome trial showing it produces the benefits marketed for it, and infused NAD⁺ is cleared from plasma quickly. Some people value the experience and the higher dose, but you should go in knowing the cost-to-evidence ratio is poor compared with oral precursors. See our NAD⁺ IV therapy review.
How is this list ordered?
Approved affiliate partners are shown first and labeled — that ordering is commercial. The written assessment is editorial and is never changed by whether we earn a commission. Importantly, our evidence framing is honest regardless of order: we say plainly that oral precursors (including the non-monetized Tru Niagen) have the better human data than the IV and injection options.
