Klean Athlete Pre-Workout is a sports supplement designed to support focus, alertness and endurance, with 75 mg of organic caffeine and 300 mg of standardized nitrates from beet root extract.
Made for athletes preparing to perform, Klean Athlete Pre-Workout brings together caffeine, beet root-derived nitrates and vitamin C in one formula. Its stated purpose is performance support rather than a promise of a particular result. The caffeine may help athletes avoid the mid-workout “bonk” by promoting focus, alertness and endurance, making the formula relevant to training and other athletic activity where those qualities matter.
It combines organic caffeine with standardized nitrates derived from beet root extract. The caffeine may support focus, alertness and endurance during a workout; these are potential benefits, not guaranteed outcomes. The formula is intended for athletes seeking pre-workout support as part of their sports nutrition routine.
Vitamin C is included to support the body's defense system and provide support against free radicals. This gives the formula an essential vitamin alongside its caffeine and beet root extract components. The stated role of vitamin C is nutritional support; it is not a claim to diagnose, treat or prevent a condition.
Klean Athlete products are third-party certified by NSF International's NSF Certified for Sport program. The certification is intended to help athletes, coaches and trainers make more informed decisions when choosing sports supplements. It provides a sports-focused certification detail for people considering supplements as part of their training nutrition.
