Ingredients
Crystal Light is sweetened with a combination of aspartame, acesulfame potassium, sucralose, and/or sugar depending on the specific product line and flavor.[13] 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.[14] In 2010, Crystal Light launched Pure Fitness, a "naturally-sweetened" low-calorie fitness drink mix[15] which is sweetened with sugar and Truvia, a sweetener derived from the stevia plant. It is currently sold in "On The Go" packets.[16] In 2011, Crystal Light Pure Fitness was renamed Crystal Light Pure, and three additional flavors were introduced.[16] In April 2012, several Crystal Light varieties were added to the line of sodamix syrups for SodaStream home soda makers.[17]
Kraft Heinz, 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.
Calories per serving have varied throughout the years; non-zero calorie flavors were once as low as 4 calories in 1990 and now, they may be as high as 15 in 2018, depending on flavor.[18] However, it's not certain if the change is due to the use of new ingredients or if serving sizes have increased.
Some Crystal Light products, notably those designated as Crystal Light Energy, also contain an appreciable amount of added caffeine. The company has even experimented with displaying a prominent "with caffeine" tag below the product name on packaging. "Crystal Light products with Energy positioning contain added caffeine," according to Kraft Heinz. "Crystal Light Energy Wild Strawberry contains 60 mg caffeine per 8 fl oz serving". In fact, all Crystal Light Energy flavors contain this same amount of caffeine.[19] Certain other Crystal Light flavors have long included caffeine as an ingredient. The label of Crystal Light Peach Iced Tea, for instance, says that the flavor contains "25mg caffeine per serving," or about as much an eight-ounce (240 mL) cup of black tea.
