Your coffee clocks out at 2 p.m. Your day doesn't.

The first cup that holds the whole day.

A morning matcha latte in place of the coffee.
Made in Osaki-cho for days that run long.

Four ingredients. Ten grams.
Nothing else.

Most brands sprinkle twenty things in milligram pinches. Nutroko puts four things in at full measure: grams, not milligrams. Of the ten grams, 5,000mg is mushroom fruiting body.

The base of the cup

Kagoshima matcha

3g every morning

Stone-milled at a family mill one town over. We buy it from people we know by name.

朝the first hours of the day

3g, weighed not sprinkled

Lion's mane, fruiting body

3g every morning

Fruiting body is the mushroom itself, not mycelium grown on grain.

午前the deep-work morning

2g, also fruiting body

Cordyceps, fruiting body

2g every morning

Cordyceps militaris. With the lion's mane, that's 5,000mg of fruiting body a cup.

午後the second half of the day

The 2g that rounds it out

Kagoshima sweet potato

2g every morning

Milled at the factory down the road, from this town's own crop.

The numbers come from the lab, not from us.

Batch 001's matcha base powder is tested by SUNATEC, an independent Japanese food analysis center. The 200-item pesticide screen came back “none detected”. Heavy metals, mycotoxins, and microbial counts are tested too.

Sixty seconds, start to finish.

Nutroko is a matcha supplement (a Japanese mushroom matcha), mixed as a morning cup. One pouch is thirty mornings. We're not asking you to quit coffee. We're asking for the first cup.

Batch 001, packed by hand.

One small run, weighed and sealed by hand in Osaki-cho, at the same local factory that makes our sweet potato powder. The batch in this photo is the one that ships in August.

No warehouse, no thousand-unit run. When Batch 001 is gone, Batch 002 is the next chance, at a higher price.

The honest part, before you find it yourself: we have zero reviews. You'd be among the first. What we can offer instead is everything you can check — a real company in Osaki-cho, Kagoshima, a town of eleven thousand; a founder with his name and face on this site; the recipe in grams; third-party results from SUNATEC; and a batch packed by hand. He answers every order email himself.
