When Sambazon was founded by three Southern California surfers in 2000, it became one of the biggest importers of antioxidant-rich tropical acai berries. Now the company is on to smoothies, and Sambazon's new Supergreens is the best to-go shake in stores now. It's packed with fiber, more calcium than milk, and three servings each of fruits and vegetables, and it has half the sugar of similar brands. (Some Naked smoothies have 60 grams of sugar, compared with 29 grams here.) Best of all, it's tasty, with sweet mango and banana balancing the greens. [sambazon.com]
