(B+Guarana). Low cal. 10 calories per serving (that's 10 minutes of online dating). Naturally sweet - supernaturally tasty. Ever have one of those days when things just seem to be longer and more difficult than they have to be? That quick catch-up turns into a yada-yada conference call, the elevator breaks en route to your 38th floor apartment, and your new personal trainer just got back from the ultraman transatlantic decathlon. Well for times like these, we packed this bottle with B vitamins and natural caffeine. It's naturally sweetened with only 10 calories per serving and will give you that extra oomph you need when catch-ups turn into memoirs, going home requires an oxygen tank, and workouts are led by guys named Maximus Von Tricepitus. Nutrient rich, calorie poor. Contains no juice.
