Voke Tab

When you need a quick pick-me-up on the trail, these 2-calorie chewable caffeine tabs give you natural energy derived from green tea leaf and guarana berry. Each serving delivers 77 mg of slow-release—therefore jitter-free—caffeine, the equivalent of one strong cup of tea. Some of our non-coffee or tea drinkers loved nibbling on a tab or two in the morning for a little kickstart. (Though some couldn’t get past the bitter taste.)
