Overview

Four Sigmatic Lion's Mane Mushroom Coffee combines organic instant coffee with 250mg of lion's mane mushroom and 250mg of chaga mushroom per packet. The formula provides about half the caffeine of regular coffee (~50mg) while adding the cognitive benefits of lion's mane (nerve growth factor support) and the immune benefits of chaga. Four Sigmatic pioneered the functional mushroom coffee category.

Our Verdict

7.2/10 — Good

Four Sigmatic created a category and remains the most recognized mushroom coffee brand. The lion's mane dose (250mg) is below the 500mg-1000mg used in clinical studies, so don't expect dramatic cognitive effects. Think of it as a healthier, calmer coffee alternative rather than a nootropic powerhouse.
