Crystal Light is sweetened with a combination of aspartame, acesulfame potassium, Sucralose, and/or sugar depending on the specific product line and flavor. First packaged in multi-serve canisters, Crystal Light launched single-serve "On The Go" packets in 2004. In 2009, Crystal Light redesigned its multi-serve packaging. On a finished case goods basis, the new design uses 250 tons less packaging than the original. In 2010, Crystal Light launched Pure Fitness, a "naturally-sweetened" low-calorie fitness drink mix which is sweetened with sugar and Truvia, a sweetener derived from the stevia plant. It is currently sold in "On The Go" packets. In 2011, Crystal Light Pure Fitness was renamed Crystal Light Pure, and three additional flavors were introduced. In April 2012, several Crystal Light varieties were added to the line of sodamix syrups for SodaStream home soda makers.
Kraft Foods, the parent company of Crystal Light, offers a product locator on its website to help locate flavors in a desired location. Crystal Light is sold in the U.S. and Canada.
