Pre-workout is a type of dietary supplement that is designed to be taken before exercise to enhance athletic performance, increase energy, and improve focus. These supplements typically come in powder or pill form and contain a variety of ingredients such as caffeine, beta-alanine, creatine, and nitric oxide precursors.

Caffeine is a central nervous system stimulant that can help increase alertness, focus, and energy levels during exercise. Beta-alanine is an amino acid that helps buffer lactic acid buildup in the muscles, which can reduce fatigue and improve endurance. Creatine is a compound that can increase muscle energy stores and improve strength and power output. Nitric oxide precursors such as arginine and citrulline can help improve blood flow to the muscles, which can enhance performance and aid in muscle recovery.

Pre-workout supplements are often used by athletes and fitness enthusiasts to help maximize their workouts and achieve their fitness goals
