Frequently Asked Questions
Everything you need to know about our mushroom coffee, proteins, and wellness elixirs.
What are functional mushrooms and will they make me hallucinate?
Functional mushrooms like Chaga, Lion's Mane, and Reishi are used to support immunity, focus, and relaxation. They are non-psychoactive and do not contain psilocybin, so they will not cause any hallucinations.
