Klean Pre-Workout is NSF Certified For Sport ® , free of artificial colors and flavors. Uniquely formulated with beet root extract along with vitamin C and organic caffeine to support athletic endurance and performance. ‡

Intense, repetitive training requires massive amounts of energy. When food alone doesn’t suffice, athletes turn to the wide world of pre-workouts. Klean Pre-Workout is uniquely designed with 300 mg of standardized nitrates derived from beet root extract, vitamin C and 75mg of organic caffeine (less than an average cup of coffee), which have been shown to support enhanced athletic performance and to protect against free radicals. Caffeine may help athletes avoid the mid-workout “bonk” by promoting focus, alertness and endurance.^‡

Klean Pre-Workout comes in a delicious natural lemon tea flavor, giving athletes a clean tasting, NSF Certified For Sport^® fuel to help achieve optimal results through each and every workout.^‡
