A pre-workout supplement is a substance designed to provide energy and stimulation, notably in sports or fitness routines. They are typically taken before a workout session and provide more benefits than a caffeinated drink like coffee. Pre-workouts contain stimulants such as caffeine, taurine, and guarana. These stimulants may give you increased concentration, focus, mood enhancement, increased metabolism (muscle growth), endurance (sustained work capacity), strength (force production) as well as mental clarity.
They also may help reduce fatigue by increasing blood flow to your muscles while giving you extra oxygen when they need it most which can make workouts feel easier. In addition they may prevent feelings of muscle cramps or nausea that occur during a workout due to low blood sugar levels.
