Vitamin gummi bears for grow-ups? I had to check them out. They have B12 & C vitamins and have guarana which is supposed to provide an energy boost. I tried the orange ones and they were pretty tasty, good chewy texture and while the orange wasn't too zesty, it was sort of jammy and pleasant. I can't say that I noticed any major energy burst but I do have a super-human tolerance for stimulants like caffeine so I am not the best judge.
