10/10 taste and perfect balance of caffeine and adaptogens
Exceptional taste and perfect balance of caffeine and mushrooms/adaptogens. I’ve been trying to cut back on caffeine and finally found something to replace my morning latte that fully satisfies my craving for a rich, creamy, delicious and energizing drink. Beyond grateful for Rainbo.

A soothing brew for sensitive stomachs
As someone with a sensitive stomach and bouts of GERD, finding a coffee that doesn’t trigger discomfort has always been a challenge. Most blends are too acidic or harsh, leaving me regretting my morning cup. Fungki Coffee has been a total game changer, the taste is smooth, creamy, and incredibly well-balanced.

Fungki Coffee from our Founder, Tonya:
Fungki Coffee was born from my need for energy that didn’t come at a cost.
I used to be a heavy coffee drinker, the kind who needed a cup to function, even though it left me wired, anxious, running to the bathroom all day and eventually crashing. By 2020, I was depleted and knew I couldn’t keep running on borrowed energy. I quit coffee because I needed a way to feel focused and alive without frying my nervous system.
That’s when I started creating my own recipe for a coffee alternative and a clean mushroom coffee that actually felt good in my body. I’d been working with functional mushrooms since 2011, but everything I tried on the market was either underdosed, lacked ingredient integrity, or tasted awful. So I made one that finally did it all: delicious, effective, and truly supportive.
Fungki Coffee is the blend I wish I had years ago. Smooth caffeine, therapeutic mushrooms, and a flavour that feels like a real ritual. It’s for the high-performers, the deep feelers, the people who want to be switched on, without burning out.
