Cirkul is transforming the way people hydrate by making drinking water delicious, convenient, and fun. Founded in 2017 by two Dartmouth athletes, Cirkul developed a revolutionary flavor cartridge that lets users customize every sip with a simple turn of the dial. Each cartridge delivers up to six drinks (just refill with water) with no sugar, zero calories, and no artificial colors. Cirkul’s vision is to turn water into every drink, for everyone, everywhere. With 150+ flavors across functional lines like Energy, Electrolytes, and Vitamins, Cirkul makes drinking more water easy all day long.
