Coffee cubes

The San Francisco-based company, which already produces a range of daily nootropics, each designed to boost specific cognitive functions including memory, resilience to stress and mental clarity, has launched Go Cubes, a chewable coffee made from cold-brew coffee.

With the consistency of a jelly sweet, each Go Cube contains 50mg of caffeine, as much as half a cup of coffee. The effects of this direct hit of caffeine on the system are counterbalanced by the presence of other nootropics including L-theanine, found in green tea, for a calmer sense of alertness.
