Frequently Asked
Is this caffeine free?
Absolutely.
What is an elixir and how do I use it?
Elixir is what we call our high dose 4 ingredient blends. Each contains a high dose of 1 functional mushroom (chaga in this case), 1 adaptogen, and field mint plus rose hips for flavor and enhanced bioavailability. We love adding a touch of cacao and the sweetener of your choice. Or you can just add to hot water, coffee, or tea.
Is this tested for toxins?
Yes, every batch is tested in 3rd party labs for heavy metals, mycotoxins, mold, yeast and pesticides.
Why Four Sigmatic?
We infuse functional mushrooms into everyday products you love, to enrich your mind and your well-being. Think lion’s mane for focus, cordyceps for energy, or reishi for a sense of calm. Our brews, blends, and powders get you in a good headspace so you can focus on what matters most. We're committed to always giving you delicious, quality organic ingredients (no filler grains, no mycelium!) so you see results in as little as seven days, at a great value. But don't just take our word for it. Read one of the 40,000+ reviews!

Nope. It tastes like coffee because it IS coffee.

Some people may call the way they make you feel magic, but these are not psychedelic mushrooms.
