More than a burst of freshness, Vojo's Extreme Energy Mints ($2; $15/8 pack) pack energy-enhancing blend of guarana, vitamin C, taurine and caffeine for a quick picker-upper. These energy mints are available in three delicious flavors including peppermint, citrus and berry. A pack of VoJo Extreme contains as much caffeine as five eight-ounce energy drinks.
