C4 Smart Energy offers innovative energy drinks that are made to provide a sustainable boost, without any unwanted additives.
The drinks spotlight key ingredients like naturally derived caffeine that comes from tea, Cognizin Citicoline, an ingredient that's said to improve focus and attention, as well as N-Acetyl L-Tyrosine, an essential amino acid that supports mental flexibility and memory. The drinks are also free of sugar, carbs and calories, and are made with no artificial colors or dyes.
The brand recently expanded its range to include a new 'Black Cherry' flavor, which is offered in both 16oz and 12oz serving sizes. C4 Smart Energy can be purchased in 12-packs from the company's web store, and comes in four other flavors, including 'Freedom Ice,' 'Cotton Candy,' 'Peach Mango Nectar,' and 'Electric Sour.'
