LifeAid Beverage Co. launched PartyAid, a functional beverage formulated to enhance, replenish and restore the body and mind before, during or after a night of partying. Containing 45 calories in each 12-ounce can, the drink is all-natural and sweetened with blue agave nectar and stevia. By fortifying partiers with ingredients that can be lost during a night out, the company says consumers can enjoy a longer evening and recover more quickly the next day. One can retails for approximately $2.99.
