NAD+ Injections vs. Nasal Spray vs. Patches: Which Form Actually Absorbs?
Buy NAD+ online and you will be asked to choose a format before you have any basis for choosing. Injection, nasal spray, oral liquid, and in the wider supplement market, patches. We checked what the six programs in our partner lineup actually sell on August 16, 2026, what each one costs, and what the companies claim about absorption. One of those four formats is not sold by any of them, which is a useful place to start.

Injection: The Default, and the Cheapest Full Dose
Four of the six programs sell an injection, and it is the format with the most published detail behind it. System Labs charges $149 a month for a 1000mg monthly supply, dropping to $89 for the first month, and specifies administration into the stomach or thigh. Wellorithm charges $200 a month after a $150 first month, includes a home kit, and breaks its own price down to roughly $15 a shot.
Lttl charges $199 month to month, or $129 on a twelve month plan. Breeze Meds lists injections from $169 but publishes no dose or billing period. Lttl states that injection offers 100 percent bioavailability, which is the company’s own claim rather than a cited finding.
The practical trade is straightforward. You are giving yourself a subcutaneous injection on a schedule, which some people find trivial and others abandon in week three. Buy the format you will still be using in month six.
Nasal Spray: The Cheapest Entry, and No Needles
Nasal is where the lowest verified price in the whole category sits. System Labs sells a 300mg/ml, 15ml nasal spray at $119 a month, or $69 for the first month, taken one spray per nostril once or twice daily as a clinician directs. That is $30 a month less than the same company’s injection.
Telos Rx sells nasal spray only, at a published $249 dropping to as low as $116 a month on its longest commitment. Telos describes intranasal delivery as bypassing the digestive tract for direct absorption through the nasal mucosa. Again, that is the seller describing its own product, not a trial result.
Lttl also sells a nasal spray, priced identically to its injection at $199 month to month. If you are undecided between routes, that identical pricing is genuinely useful, because switching costs you nothing.
Oral Liquid: One Seller, Same Price
Only Lttl sells an oral option among the programs we verified, a liposomal liquid at $199 month to month. Liposomal formulation is the company’s stated approach to improving uptake of a compound that oral delivery otherwise handles poorly.
Worth knowing: most of the human research on raising NAD+ levels studies oral precursor compounds rather than oral NAD+ itself. Those are not the same product. We cover that distinction in detail in our piece on what NAD+ therapy does and does not do.
Patches: Nobody Vetted Sells One
NAD+ patches are widely marketed online, mostly as unregulated supplements rather than prescribed compounded medication. None of the six telehealth programs we checked offers one. That is not a verdict on whether patches work. It is a straightforward observation that the licensed, clinician gated side of this market has not adopted the format.
If a patch is what you want, you are shopping in the supplement aisle, not the telehealth market, and the safeguards differ accordingly. There is no prescriber, no compounding pharmacy and no clinician review in that transaction.
Which Format Actually Absorbs Best?
We could not find head to head human trials comparing injected, intranasal and oral NAD+ absorption, and no seller in this lineup cited one. Every absorption claim we encountered came from the company selling that format.
So the choosing rule has to be practical rather than pharmacological. Pick on adherence, price and dose transparency. On price, nasal wins at $119. On published dose detail, System Labs wins in both formats. On flexibility, Lttl wins by charging the same for all three.
Common Questions About NAD+ Formats
Is injection stronger than nasal spray?
Sellers imply it, but no head to head human comparison surfaced in our check. The doses are also specified differently, so the two are not directly comparable on the label alone.
Can I switch formats later?
With Lttl the price is identical across injection, nasal and oral, so switching costs nothing. Elsewhere you would be moving between differently priced products, and at System Labs that is a $30 a month difference.
What is the cheapest needle free option?
System Labs nasal spray at $119 a month, or $69 for the first month. That is also the cheapest NAD+ product of any format across the six programs we verified.
