Do any flavors of CLIF BLOKS contain caffeine? Why?

Yes, three flavors of CLIF BLOKS contain caffeine. Caffeine is an effective performance-enhancing ingredient that is known to give athletes a boost and can help enhance mental alertness. We use green tea extract as our source of caffeine and have a special label on the packages of those flavors so you can easily tell that they contain added caffeine. Black Cherry Flavor CLIF BLOKS contains 50mg of caffeine per serving. The Orange Flavor and Tropical Punch Flavor contains 25mg of caffeine per serving. Caffeinated flavors of CLIF BLOKS are not intended for individuals under 18 years of age, pregnant or nursing women, or for those sensitive to caffeine.
