This was a scary line-up against the finest "superjuices" on the market. Sharpen up fared pretty well, but Suzi liked the pure organic juices of James White and RDA best... Can't win 'em all.

Suzi says: "Mate, guarana and Siberian ginseng are all natural stimulatnts, but because of the high fruit content it may make some people sleepy. You'd be better off taking the guarana and ginseng on their own, but if you like having it in your fruit juice, then this is fine."
