Pre-workout supplements are formulated to boost energy, focus, and endurance during exercise sessions. Typically containing ingredients like caffeine, beta-alanine, and creatine, they aim to enhance performance by increasing alertness, buffering muscle fatigue, and supporting strength and power output. Nitric oxide precursors such as L-arginine or citrulline are also common additions, promoting better blood flow to working muscles for improved nutrient delivery and muscle pump. While pre-workout supplements can be effective in enhancing workout performance, it's essential to use them as part of a balanced fitness regimen and consult with a healthcare professional for personalized guidance.
