Do NAD+ Patches Work? What the Evidence Shows

Disclosure: PrescribedRX sells its own treatments, so we compete with some of the companies covered here, and we may earn affiliate commissions. PrescribedRX is a telehealth platform; prescriptions are written by licensed clinicians and filled by licensed partner pharmacies.

Short answer: No published study has shown that NAD+ patches, a skin-based form of NAD+ therapy, raise NAD+ levels in people. NAD+ has a molecular weight of 663.4 daltons (PubChem), above the roughly 500-dalton limit for skin absorption proposed by dermatologists Bos and Meinardi (Bos and Meinardi, 2000), and published skin-delivery studies have used lab models or skin samples, not living people. A 2026 systematic review of NAD+ supplementation covered only oral and injected routes, so patches were not part of the evidence it assessed (Gallagher and Emmanuel, 2026).

Below: what one patch on sale lists on its label, the size problem, and the only published research on getting NAD+ or its precursors through skin. We took the same approach in our review of GLP-1 patches.

What is an NAD+ patch?

An NAD+ patch is an adhesive patch, sold without a prescription, that lists NAD+ or an NAD+ precursor among its ingredients. NAD+ (nicotinamide adenine dinucleotide, listed in PubChem as nadide) is a coenzyme found in cells (PubChem). Nicotinamide mononucleotide (NMN) and nicotinamide riboside (NR) are precursors, the raw materials the body uses to make it. Our NMN vs NAD+ comparison explains the difference.

Patches like these are sold online as wellness products, without a prescription (PatchAid).

What do NAD+ patches actually contain?

Here is what one seller lists for its NAD+ patch, as an example. This is what the listing says, not a test of what the patch contains or delivers.

Product, as listed in October 2026	Listed ingredients per patch	Listed wear time	Listed price
PatchAid NAD+ Patch	NAD+ 600 mg, resveratrol 150 mg	Up to 8 hours, once a day	$24.95

The listing gives an NAD+ amount per patch but does not state how much, if any, passes through the skin (PatchAid). The next section explains why that question matters for NAD+ in particular.

Can NAD+ get through the skin?

Size is the first hurdle. In a widely cited paper, Bos and Meinardi argued that a compound’s molecular weight “must be under 500 Dalton to allow skin absorption,” noting that all known drugs used in transdermal delivery systems at the time were under that limit (Bos and Meinardi, 2000). It is a rule of thumb, not a law.

Molecule	Molecular weight (daltons)	Compared with the 500 Da rule of thumb
NR (PubChem)	255.25	Under
NMN (PubChem)	334.22	Under
Rule of thumb (Bos and Meinardi)	500	Threshold
NAD+ (PubChem)	663.4	About 1.3 times over

NAD+ sits above the threshold. NMN and NR sit below it, so size alone does not rule them out. Being small enough is not proof of absorption, though.

Has any study tested NAD+ patches in people?

No published study has tested an NAD+ patch in people. Published patch, microneedle and skin studies of NAD+, NMN or NR are lab and skin-sample work, and ClinicalTrials.gov lists no registered trial of an NAD+ patch (ClinicalTrials.gov). The 2026 systematic review of NAD+ supplementation covered compounds “administered orally or parenterally” (by mouth, injection or IV), so it did not include patches; it found clinical effectiveness for anti-aging or wellness outcomes “remains inconclusive” for the routes it did cover (Gallagher and Emmanuel, 2026).

The closest published research:

• Kang 2026, a specially engineered NAD+ carrier. Researchers built an “ion-coupled NAD+ transfersome” and tested it in cells, in pig and human skin explants (skin samples removed from the body) and in C. elegans worms. They reported better NAD+ penetration into the skin samples than with free NAD+ or precursors. Nine authors were employees of LG Household & Health Care. No living people were tested, and the carrier is not the plain adhesive patch on sale (Kang et al., 2026).
• Sabbagh and Kim 2023, NMN microneedle patches. Patches with dissolving microneedles released up to 91.94% of their NMN over 18 hours in an ex vivo (outside the body) test. This measured release from the patch, not levels in a person (Sabbagh and Kim, 2023).
• Betsuno 2025, NMN on an artificial skin membrane. NMN in a cosmetic filtrate was detected only in the upper dermis layer of a synthetic membrane, and the authors concluded it “did not reach the subcutaneous tissue” (Betsuno et al., 2025).

None of these measured NAD+ in the blood or cells of a person wearing a patch. That is the measurement a claim like “delivers NAD+ through the skin” would need.

NAD+ patch claims vs the evidence

What patch marketing says	What the sources say	Source
“Delivers NAD+ through the skin”	NAD+ is 663.4 Da, above the roughly 500 Da rule of thumb for skin absorption; no published human blood-level study	PubChem, Bos and Meinardi
“Backed by research”	Published skin-delivery studies used cells, skin samples, synthetic membranes or worms, not people	Kang 2026, Sabbagh 2023, Betsuno 2025
“Raises your NAD+ levels”	No published study has measured NAD+ in the blood or cells of people wearing a patch, and a 2026 systematic review of NAD+ supplementation did not cover patches	ClinicalTrials.gov, Gallagher 2026

How do patches compare with other NAD+ forms?

Every form has gaps, but they are different gaps. In the trials cited in our NAD+ supplements vs injections guide, oral NR and NMN raised NAD+ in blood or blood cells, while a 2026 review described effects on health outcomes as “heterogeneous and often null or endpoint-specific” (Gallagher and Emmanuel, 2026). For oral liposomal NAD+, there is no published human absorption study (our liposomal NAD+ review). For patches, there is no published human study of any kind. What has been published about the injected route is covered on our NAD+ injection evidence page.

Form	Published human NAD+ level data	Prescription needed?
Oral NR or NMN	Yes, in blood or blood cells (see linked guide)	No
Oral liposomal NAD+	None published	No
NAD+ or NMN patch	None published	No
IV NAD+	Plasma and urine during one 6-hour infusion pilot (see linked guide)	Given in clinics
Compounded NAD+ injection or nasal spray	None published	Yes

A licensed provider decides whether it is appropriate for you, and your provider sets the dose. Plans are self-pay and availability varies by state. Every plan is on our pricing page.

When should you talk to a doctor?

Talk to a licensed provider before using an NAD+ patch if you take medicines or have a health condition. The PatchAid listing says its patch contains resveratrol, “which may affect blood clotting,” and tells anyone who takes a blood thinner or antiplatelet medicine, has a bleeding disorder or has surgery scheduled to speak with a provider first. It also says to stop use if you have irritation or a reaction, and not to use it on broken or irritated skin (PatchAid). In an emergency, call 911.

NAD+ patch FAQ

Do NAD patches work?

No published study has shown that any NAD+ patch raises NAD+ in people. NAD+ is larger than the roughly 500-dalton rule of thumb for skin absorption, published delivery studies used lab models and skin samples, and a 2026 systematic review of NAD+ supplementation did not include patches (Gallagher and Emmanuel, 2026).

Are NAD patches better than injections?

No published study has compared them. There are no published human data for NAD+ patches, and a 2026 systematic review found no eligible outcome trials of IV or intramuscular NAD+. Without measurements for either, the evidence cannot say one is better.

Talk to a licensed provider about NAD+

If you want a licensed provider to review whether a prescription NAD+ product is appropriate for you, start with the eligibility check. NAD+ Injection and NAD+ Nasal Spray are compounded, and the price is shown before you pay: “3 month plan $412 · $137/mo · Billed every 3 months. Cancel anytime.” You can also browse all longevity treatments.
