Formula O2 launched a new line of oxygenated energy drinks in 16-ounce Rexam cans. Formula O2 recovery drinks are infused with 10 times more oxygen than tap water to help eliminate toxins, 2.5 times more electrolytes than leading sports drinks, and 140 mg of natural caffeine, the company says. The company chose aluminum cans for the launch of formula O2 because they offer optimum barrier properties that protect the integrity of the oxygen content in the product and offer portability and sustainability features, it adds.
