Pyure Brands will launch a zero-calorie organic energy shot under the name of Pyure Organic Energy Optimization, or O.E.O. for short. The 2-ounce shot contains organic, energy-boosting ingredients, including green tea, yerba mate and guarana, and is sweetened with organic stevia, the company says. The energy shot comes in Mixed Berry and Citrus flavors and is targeted at consumers seeking a healthier alternative to traditional energy shots. One bottle has a suggested retail price of $3.39. Distribution will begin soon within natural grocery channels, the company adds.
