Developed by a board-certified clinical neuroscientist, ON Beverages’ ON Powered Refreshment functional drinks feature a blend of ornithine, caffeine from tea leaf extract, and B vitamins for energy.

The line is available in Blueberry Lemonade, Tropical Citrus, Dragonfruit Tangerine, Peach Mango and Raspberry Limeade flavors. A 16.9-ounce bottle has a suggested retail price between $1.99 and $2.49.
