A glass of natural juice can give its drinker enough energy to stay awake through the long workday or at least through a 40-hour opera performed by 5-year-olds. Boost your bone cage with today's Groupon: for $5, you get your choice of two smoothies or juices at Natureba Juice Bar in Redondo Beach (up to a $10.90 value).

Natureba Juice Bar quenches thirsts with 100% all-natural fruit juices and smoothies. Unlike the sugar-laden dreams of toddlers, the Brazilian-style nectar house overflows with a blossoming variety of liquefied fruitage, including apples, beets, celery, mangos, and papaya blended into quenching serums. Guest drinkers can also slurp down a mix of more uncommon vitamin-packed morsels from tropical climes such as cashew fruit, cacao, capuaçu, and acerola. Natureba also proffers 30 smoothie options, such as the Orangatang's pineapple, passionfruit, and soy milk mélange and the blend of açai, banana, and guarana in the Anti-Ox smoothie, with a tendency to melt across the palate as effortlessly as a snowflake on a date with a tongue. The produce-packed storefront's staff can also blend veggies⎯carrots and spinach⎯or vanilla whey protein into several of their handheld fruity libations.
