What's That Patch review
NMN, not NAD
The most transparent ingredient list of any patch in this format, and what it reveals is that the NAD⁺ patch contains no NAD⁺.
Our verdict
Credit where it is due: this brand prints every ingredient and every amount, which is more than most of this category will do. Read the list and the product dissolves. A patch sold as NAD+ Longevity contains 8 mg of NMN, 5 mg of resveratrol, 5 mg of NAC, 5 mg of lion's mane and 2 mg of cordyceps — and no NAD⁺ at all. NMN is a precursor the body converts into NAD⁺, so the naming is not baseless, but 8 mg sits far below every dose used in the published human NMN trials, which run from 100 mg to 1,000 mg twice daily. Transparency this good is normally a reason to buy. Here it is the reason not to.

Anyone who wants the price up front
Check Care Bare Rx availability →What it is
A daily adhesive patch, thirty to a month, worn for eight hours, sold direct to consumer as part of a range that also includes sleep, creatine, collagen and focus patches. The brand prices in pounds and ships from the United Kingdom.
How it works
Retail only. No clinician, no intake, no prescription — a consumer product bought from a web store like any other supplement.
Pricing transparency
£19.00 for a month, £16.15 on a subscription at 15% off, with two- and three-month packs at £33.00 and £49.00. There is no dollar price on the product page, though the marketing copy advertises less than a dollar a day, so a US buyer is paying an exchange rate plus international shipping on top of the listed figure. On sticker price this is at the cheap end of the format; on price per milligram of anything the body converts to NAD⁺, it is not cheap at all.
Branded vs compounded
A supplement, not a drug. It is not FDA-approved and the FDA does not review products in this category for safety or effectiveness before sale. The evidence section links studies of the individual ingredients — NMN, resveratrol, NAC, lion's mane, cordyceps — rather than any study of this patch, and those ingredient studies test oral dosing, which is a different route at a different scale.
Pros and watch-outs
What we like
- Publishes every ingredient with its milligram amount, which is rare in this format
- Cheap by the standards of the category, with no subscription required
- Names its evidence rather than gesturing at science generally
- Says plainly that the patch is worn for eight hours and then discarded
Watch-outs
- Contains no NAD⁺, despite being sold as an NAD⁺ patch
- 8 mg of NMN is a small fraction of the doses used in published human NMN trials
- The 97% and 86% figures come from the brand's own preference survey, not a trial
- The linked ingredient studies test oral dosing, not a patch
- Priced in pounds, so a US buyer pays currency conversion and overseas shipping
Best for
Nobody shopping for NAD⁺. If you want this specific blend of botanicals and a small amount of NMN on your skin, the label at least tells you exactly what you are getting.
Who should look elsewhere
Anyone who read the product name and assumed it described the contents. Read the ingredient list first — on this page it is the whole review.

Frequently asked
- Does this patch contain NAD⁺?
- No. The published ingredient list is NMN 8 mg, resveratrol 5 mg, NAC 5 mg, lion's mane 5 mg and cordyceps 2 mg. NAD⁺ appears in the product name and nowhere in the formula.
- Is NMN the same thing as NAD⁺?
- Not the same, but related: NMN is one step away, a precursor your body converts into NAD⁺. That conversion is real and is why oral NMN raises blood NAD⁺ in human trials. Those trials used doses from 100 mg up to 1,000 mg twice daily, taken by mouth. This patch carries 8 mg, applied to skin.
- What does the 97% figure mean?
- It comes from the brand's own eight-week consumer study and describes how many people said they would choose the patch over pills. It is a preference survey. It reports no NAD⁺ measurement, no comparison group and no clinical outcome, and it should not be read as evidence that anything was absorbed.
- How much does it cost in dollars?
- The store prices in pounds — £19.00 for a month, £16.15 on a subscription — so a US buyer converts at whatever rate applies on the day and pays international shipping. The less-than-a-dollar-a-day line in the copy is a marketing figure, not a checkout price.
