Why ours actually does something
Fruiting body only
We use the actual mushroom, where the active compounds concentrate, not grain-grown mycelium.
Dual extraction
Water pulls the beta-glucans, ethanol pulls the compounds a plain hot-water extraction misses. You get both, not half.
Tested and disclosed
Every batch is third-party tested for potency and heavy metals, with the numbers on the label.

The receipts
Someone's name is on this
Most functional mushrooms are grown in facilities that won't put a name to them. Ours are grown by Tadashi, a cultivator whose family has grown mushrooms for generations, rooted in Gunma, Japan. He grows them here in LA, the same mushrooms we sell to Michelin kitchens.
We don't manufacture supplements. We grow mushrooms. The standard isn't a marketing claim. It's whether he'd serve it.
We grow it. Then we eat it.
Yamabushi started as a mushroom farm in Los Angeles, supplying chefs who can taste the difference between real fruiting body and grain filler. Our tinctures are made from the same mushrooms we sell to Michelin-star kitchens, because we wouldn't put our name on anything we wouldn't cook with ourselves.
How to use it
1. Shake the bottle. The good stuff settles, so give it a few shakes first.
2. Two full droppers. That's one daily serving. Take it straight, or stir it into coffee, tea, or water.
3. New to it? Start in a drink. It's an earthy, mushroom-forward taste. Mixing it into a drink the first few times is an easy way to ease in.
4. Once a day. The benefits build with daily use, so consistency matters more than timing.

FAQ
How is this different from capsules?
Most capsules are mycelium grown on grain, so you're swallowing starch with a little mushroom in it. Ours is 100% fruiting body, dual-extracted into a tincture. More of the active compounds make it in, and they absorb quickly. Same mushroom we sell to Michelin kitchens, in a form your body can actually use.
When will I feel something?
It works by supporting your body over time, not by hitting you like caffeine. Some people notice a difference in the first few days. For most, the fuller effect builds over two to four weeks of daily use, which is why staying consistent matters.
Is it safe? What about heavy metals?
Mushrooms absorb whatever's in their environment, which is exactly why where they're grown matters. Ours are grown in a controlled farm in LA, not an unregulated overseas facility, and every batch is third-party tested for heavy metals. The numbers are on the label, not hidden behind a "proprietary blend." If you're pregnant, nursing, or on medication, check with your doctor first.
How do I take it?
Two full droppers a day. Take directly and swallow, or stir it into coffee, tea, or water. New to the taste? Mixing it into a drink the first few times is the easy way in.
How does the subscription work?
A fresh bottle ships on your schedule at a lower price than one-time. Skip, pause, or change the date anytime, and cancel in two clicks with no fees or phone calls. Most people land on monthly, since one bottle is about a month of daily droppers.
Is this fruiting body or mycelium lion's mane?
100% fruiting body, the actual mushroom, grown on our farm in Los Angeles. No mycelium on grain and no fillers. The compounds people take lion's mane for concentrate in the fruiting body, which is why that's the only part we use.
Does MEZAME contain caffeine?
No. Lion's mane isn't a stimulant, so there's no jolt and no crash, and you can take it any time of day. If you want the version with a clean lift, that's IBUKI.
Does the tincture contain alcohol?
Yes, a small amount. Dual extraction uses both water and alcohol because some of the mushroom's compounds only dissolve in one or the other. A daily serving is two droppers, so the amount involved is minimal. If you avoid alcohol entirely, our capsules are the alcohol-free option.
Can I take MEZAME with IBUKI or MAMORU?
Yes, they're made to work together. A common routine is MEZAME in the morning for focus, IBUKI on days you need energy, and MAMORU any time since it has no caffeine. Start with one, get consistent, then add from there.
