A decade of user research
I'm Adam Tillner-Smith, a product designer and user researcher. For over a decade my job has been to understand a problem properly, then build something that genuinely helps.
I'm not a doctor — I read the evidence, talk to the people living it, and build the honest version.
Built on evidence, not loose claims
Every ingredient is here because the human research backs it — not because it looks good on a label.
And we only say what we can stand behind. No miracle promises, no borrowed science, nothing we couldn't defend.
Six ingredients. No fairy dust.
Six active ingredients, each dosed at the level its research actually used — not sprinkled in at trace amounts to pad a label, the way most greens powders do.
We were just as careful about what we left out. If it didn't earn its place, it isn't in the sachet.
An evening ritual, not just a drink.
Kinn isn't just a drink. Each sachet comes with a simple evening programme that helps you get the most from the ritual.
The drink is the anchor — doing it consistently is what makes it work.
A good day starts the night before.
One honest drink, at the end of the day. Everything we've talked about, in a sachet.
