Legendary body-hacker Tim Ferriss is affiliated with a company called Four Sigmatic that sells mushroom coffee, which claims to combine the focus and concentration of coffee, along with anti-inflammatory benefits from mushroom supplements like chaga, reishi, and lion’s mane.

The caffeine properties are relatively small, but the lion’s mane and other supplements within are meant to increase productivity and focus throughout the day, which trumps regular coffee in the long run.

Right now, nearly their entire product catalog is on sale for the next few days, giving you the perfect opportunity to test out the Limitless-style java alternative and see if it elevates your mood and brain in the right ways.
