Four Sigmatic Mushroom Coffee with Lion's Mane
by Four Sigmatic
"Coffee meets functional mushrooms — organic instant coffee with lion's mane and chaga for focused, jitter-free energy"
Overview
Four Sigmatic Mushroom Coffee combines organic instant coffee with lion's mane mushroom (for cognitive enhancement and NGF stimulation) and chaga mushroom (for immune support and antioxidant protection). Each packet provides approximately 50mg of caffeine (half a regular cup) plus the functional benefits of dual-extracted mushroom powders. The reduced caffeine combined with lion's mane's calming nootropic effects creates a focused, jitter-free energy experience. Four Sigmatic pioneered the functional mushroom coffee category and remains the market leader.
