Crank Focus

The ESN Crank Focus is a combination product of caffeine and L-theanine. This is a capsule booster for your training or as a pick-me-up in between. 100 mg caffeine and 100 mg L-theanine in the ideal 1:1 ratio are not too strong and not too weak, perfect for the daily midday slump or to get a little caffeine kick before your training sessions. Caffeine helps fight tiredness and fatigue, but it can also make you jittery and hyper. The L-Theanine is the antagonist that ensures that the jitters from caffeine don't occur.

Caffeine and theanine are a powerful combination for enhancing fitness performance. Caffeine stimulates the central nervous system, increasing alertness, focus, and endurance. Theanine, an amino acid found in tea, promotes relaxation and reduces the negative effects of caffeine. Together, they can improve mental and physical performance, allowing for longer and more intense workouts. Studies have shown that caffeine and theanine can increase strength, power, and endurance in athletes, while also reducing perceived exertion and fatigue.
