See the science ↓Five reasons it earns a place
in your daily ritual
It supports your body's own energy systems, gently and over time. Here's where people feel it most.
Energy
Supports cellular oxygen use and ATP production for steady, slow-burn energy, the opposite of a caffeine spike.
Focus
Paired with green tea's L-theanine, it promotes a calm, clear-headed alertness that holds through long work blocks.
Immunity
Bioactive compounds are traditionally used to support a resilient immune response and everyday defence.
Endurance
A long-standing favourite among athletes for stamina, recovery and sustained physical output.
Stress adaptation
As an adaptogen, it helps the body modulate stress, bringing you back to baseline instead of wired or wiped out.
What is Cordyceps?
A high-altitude Himalayan fungus, used in traditional medicine for centuries and now studied for how it supports the body's own energy systems.
We use only the fruiting body: the actual mushroom, not the grain it is grown on, where compounds like cordycepin and adenosine are concentrated.
The science is about energy at the cellular level. Cordyceps is studied for supporting ATP production and oxygen use, the slow-burn fuel your cells run on, while acting as an adaptogen that helps the body meet stress with balance instead of overstimulation.
Green tea + Cordyceps is more than the sum of its parts
L-Theanine
An amino acid in green tea that smooths the edge off caffeine. Calm attention, no jitter.
Adaptogens
Cordyceps' cordycepin and adenosine support sustained energy and stress balance.
One supplies the clarity, the other the fuel. Lift and composure, in the same cup.
Not all Cordyceps is created equal.
Most of it isn't even Cordyceps.
A lot of the market sells dried mycelium grown on grain, mostly starch, barely any active compound. Green Zen is built the harder, honest way.
100% fruiting body
We use the actual mushroom, never mycelium-on-grain filler. That's where the cordycepin and adenosine actually live.
Lab-tested potency
Cultivated in a controlled environment for full traceability, and third-party tested so what's on the label is what's in the cup.
Pure and consistent
Grown in a controlled environment, never foraged. Every batch is the same clean, traceable quality, with no wild variation and no contamination.
Clean by default
Whole-leaf green tea. No added sugar, no artificial preservatives, pesticide/herbicide-free, and fully vegan.

No measuring, no mess. One sachet is all it takes.
