INSIDE THE RESEARCH
The findings. In focus.
A closer look at published research on ingredients and skin delivery. These studies tested other formulations or routes of use, not finished 24/sync patches. They provide scientific context, rather than evidence of results from our products.
TOPICAL CAFFEINE · HUMAN SKIN
Caffeine can cross the skin.
Researchers measured caffeine passing through human skin and examined the contribution of hair follicles. A useful insight into skin delivery, from a topical caffeine formulation rather than an Energy patch.

NR and cellular NAD+.
In a controlled human trial, oral nicotinamide riboside increased measures of NAD+ metabolism. NR is a precursor to NAD+. This finding concerns oral supplementation; patch delivery and longevity benefits were not established.

Green tea, in patch research.
An experimental adhesive patch delivered caffeine and green-tea catechins across pig-ear skin in a laboratory study. The research demonstrates feasibility for that formulation; it did not test absorption or benefits in people.

The formula matters.
In an eight-week study of 29 runners, oral iron improved iron stores while the iron patch tested did not. A reminder to judge delivery by the specific product, rather than the format alone.

The things you want to know.
Why choose a patch?
For the ease of a format you wear. There is no drink to prepare or tablet to swallow, and each pouch contains 30 patches. Choose your patch by its ingredient profile and follow the instructions supplied with it.
How much does the skin absorb?
Absorption depends on the ingredient, formulation and conditions of use. An amount listed in a patch describes what it contains; a delivery study measures how much crosses the skin. Those are two different measurements.
What can ingredient research tell me?
It explains what scientists have observed for a particular ingredient, dose and method of use. Our research notes keep those details visible, so you can understand each finding without assuming every formula delivers the same result.
Are 24/sync patches clinically proven?
We do not currently have verified human trials establishing absorption or health benefits for finished 24/sync patches. The studies above explore the wider science and do not establish clinical results for our products.
