Designed to improve exercise performance, non-stimulant pre-workout supplements avoid depending on coffee or other stimulants. Using components like citrulline malate, beta-alanine, and creatine, these supplements usually center on enhancing blood flow, muscle endurance, and mental clarity. For people sensitive to stimulants, evening athletes, or those trying to cut caffeine intake, they're perfect. Non-stim pre-workouts seek to increase exercise intensity and results without generating jitters, energy crashes, or sleep disturbances sometimes seen with stimulant-based substitutes.
