Both blends are designed to support energy, cognitive health, and stress resilience, but the difference comes down to caffeine and taste. 

• Fungki is your caffeine-free coffee alternative, made with functional mushrooms, prebiotic herbs, and spices for grounded energy without the jitters. It features Lion’s Mane, Reishi, Cordyceps, chicory, mesquite, vanilla, cinnamon, and Himalayan salt, giving it a rich and roasted flavour profile of its own. 

• Fungki Coffee contains 44mg of low-acid caffeine from cold brew coffee, and decaf coffee, Lion’s Mane, Reishi, Ginseng, and Himalayan salt. It’s crafted for those who want the ritual and taste of coffee with balanced, nootropic energy, containing less caffeine than a typical cup, yet still enough to give you a lift.

Fungki and Fungki Coffee were formulated with integrity and intention. Each serving delivers one of the highest clinical doses of functional mushrooms on the market, 3g of fruiting body mushrooms - not mycelium or fillers - along with gut-loving, adaptogenic herbs. It mixes easily with hot or cold liquids, no blender required.

When we created these products, taste, quality, and sourcing were non-negotiable. We wanted something we felt proud to drink every day - made from ingredients we trust, in doses that actually make a difference. Many mushroom coffees out there didn’t check all those boxes for us, so we made one that did. We believe Fungki stands out for its potency, flavour, and transparency. Try it and feel the difference for yourself.

You can absolutely combine both. Fungki delivers a therapeutic 3g dose of mushrooms per serving, and if you’re also using our tinctures, you’re still well within the daily recommended limits. These mushrooms work synergistically, and combining formats can offer broader support, especially if you’re working with specific health goals.

You’re not alone, mushrooms aren’t everyone’s favourite flavour. But good news: Fungki and Fungki Coffee don’t taste like mushrooms at all!

Fungki has a smooth, roasted profile with hints of vanilla and cinnamon, think cozy herbal elixir. Fungki Coffee tastes like a bold, satisfying cup of coffee, with no mushroom flavour in sight. We crafted both with taste in mind, so your daily ritual tastes as good as it works.

Fungki + Fungki Coffee were made to be versatile. Enjoy them however you like your coffee or tea.

They’re delicious on their own, but they also make a beautiful base for a latte. Add your favourite milk (oat, almond, coconut, whatever you love) and a touch of honey or maple syrup if you prefer it a little sweeter. We kept it unsweetened so you can make it your own.

It depends on your health goals.

Fungki + Fungki Coffee deliver a therapeutic dose of 3g of fruiting body mushrooms per serving, so they can absolutely serve as your daily functional mushroom supplement for general well-being.

That said, consistency is key. If you’re not drinking Fungki or Fungki Coffee every day, we recommend continuing with your mushroom tinctures or supplements to maintain steady support. Fungki can then act as a powerful boost when added to your routine.

And if you’re looking for more targeted support, like extra Lion’s Mane for brain health or Reishi for stress, you can always layer in specific tinctures to deepen the benefits. Think of Fungki or Fungki Coffee as a solid foundation, and tinctures as precision tools for your personal wellness needs.

Rainbo’s tinctures will always be made with mushrooms grown in Canada— this part of our foundation hasn’t changed.

With Fungki, we searched high and low across North America for organic, 100% fruiting body mushroom extract powders that met our standards — and came up short. That’s why we turned to the ancestral home of mushroom cultivation: the remote and pristine mountains of China, where mushrooms have been grown for over 800 years using traditional, organic practices. 

After extensive research, vetting, and third-party testing, we partnered with multi-generational farmers who grow fruiting-body-only mushrooms on wood-based substrates (never grain), dry them in solar-powered facilities, and rigorously test for purity, beta-glucan content, and bioactive compounds.

This isn’t a compromise. It’s an evolution of our sourcing — guided by integrity, reverence for ancient wisdom, and an uncompromising commitment to quality. Fungki reflects our vision: the most effective, planet-forward mushrooms in the world, delivered to you with transparency and care.
