How it compares
Unlike standard grocery store coffee, Four Sigmatic adds dual-extracted Lion's Mane and Chaga mushrooms. This combination effectively buffers the acidity and jittery effects of caffeine. In the functional Health & Wellness beverage market, it outperforms plain yerba mate or synthetic energy drinks by providing whole-food nutrients and antioxidants alongside natural stimulation.
How to use it
- Measure 4 tablespoons of coffee for every 12 to 15 ounces of water.
- Brew using your preferred method, such as a drip machine, French press, or pour-over.
- For a cognitive boost, consume mid-morning when cortisol levels beginning to dip.
- Avoid using boiling water to prevent scorching the delicate mushroom extracts; 195-205°F is ideal.
- Store the coffee in the original bag or an airtight container in a cool, dark place for maximum freshness.

Sustainability & ethics
Four Sigmatic sources only USDA Organic and Fair Trade certified beans, ensuring farmers are paid living wages. Their mushrooms are log-grown rather than grown on grain, which results in a more potent, nutrient-dense final product. The brand also utilizes recyclable and partially compostable packaging to minimize its carbon footprint.
Pro tip
Try adding a splash of oat milk and a dash of cinnamon to complement the slightly earthy, nutty undertones of the Lion's Mane mushroom.
