Crystal Light Pure Fitness is the brand’s first low-calorie fitness beverage mix with no artificial flavors, colors, preservatives or sweeteners. It’s sweetened with evaporated cane juice and Truvia, an all-natural, calorie-free sweetener derived from the stevia plant.

With 15 calories per 8-ounce serving and electrolytes to aid hydration, Pure Fitness provides an option for women on-the-go. Each packet will transform a 16.9-ounce bottle or glass of water into a light beverage. Pure Fitness is caffeine and gluten free, and one 8-ounce serving contains three grams of sugar.
