For the nature

Take a time out to walk in the woods with us, appreciating all there is that nature has to give us.

From The Nature


Ingredients as nature intended

Nature knows best. So why mess with the best of the best? That means sourcing functional mushrooms grown on logs or wildcrafted, and only the fruiting bodies. That looks like whole real adaptogens, superfoods, herbs and spices that are never isolates, or synthetics, with absolutely no fillers.

Picking Mushrooms

We love trees so mush

Functional mushrooms like Chaga, Reishi, and Lion’s Mane grow on trees. Our Finnish founders grew up wandering through the Finnish forests to forage Chaga which led to immense respect for nature. With this as a key value of ours, we’ve partnered with tentree to become climate+ by planting 40,000 trees!

Climate plus

Climate+ goes beyond net zero carbon emissions. Rather than just offsetting carbon emissions, we are creating an environmental benefit by removing additional carbon dioxide from the atmosphere.

We are planting 40,000 trees to absorb the amount of CO2 we release. That will lead to 13,600 metric tons of CO2 absorbed over 10 years.



Plant-based and vegan, always

Bringing more plants and fungi to the table is not only good for you, but good for the planet. Eating plants and fungi requires fewer resources, from energy to water, than a standard meat-heavy diet. We are a 100% vegan company.

USDA Organic


Only the cleanest ingredients out there

Just like you, we want food the way nature intended. That means always using functional mushrooms, adaptogens, and superfoods that are 100% USDA organic. Mushrooms must be organic to be functional, as they absorb a lot from the environment they are grown in. If you want to geek out more about mushroom growing, check out Mushroom Academy®!

Tea leaf in hand


Ingredients straight from the source

Our goal is to bring you the best of nature, while being gentle on the earth. We proudly source the most nutrient dense ingredients on the planet from around the world, choosing countries of origins where these ingredients are native to. That means Ayurvedic herbs like Tulsi (Holy Basil) and Ashwagandha from India, to Coffee and Cacao from South and Central America.
