Think Organic Coffee with Lion's Mane

Mushroom coffee sounds cool, and Four Sigmatic made it mainstream. But 250mg lion's mane when studies use 1000-3000mg means you're paying $5/cup for coffee with a mushroom sprinkle. Buy regular coffee + a lion's mane capsule for 10x better value.

5.5/10
DECENT

Same fundamental problem as the other Four Sigmatic coffees. Lion's Mane at 250mg is 50% of minEffective and 25% of optimal. Chaga at 250mg is 50% of minEffective. Dual extract helps but can't overcome a dose that's a quarter of what studies use.
