    Optimum Nutrition presents Performance energy, a powerful energizing supplement that supports intense energy and focus during workouts and fast recovery following exercise. With an advanced blend of caffeine, beta-alanine, branched-chain amino acids and more, each scoop of Performance Energy can energize your fitness and daily activities all day long without the crash or obnoxious jitters. The sugar free, artificial color free, and articifial flavor free formula is available in delicious fruit punch flavor with just 10 calories per scoop.

    Each serving of Performance Energy provides about the same amount of caffeine as a cup of coffee. Caffeine stimulates the central nervous system to increase energy and metabolism. Caffeine intake increases exercise performance capacity and breakdown of fat stores.[1] Caffeine intake increases power output, time to exhaustion, and oxygen utilization for improved anaerobic performance.[2]

    Performance Energy also provides approximately 5 grams of amino acids per scoop to suppot muscle recovery and maintenance. Branched-chain amino acids activate key enzymes in protein synthesis after physical exercise, improving muscle building and recovery.[3] Leucine, for example, has been shown to enhance recovery of skeletal muscle following exercise.[4]

    Performance Energy can be enjoyed any time of a day as a substitue for cofee, tea, and soft drinks for a low-calorie option to fuel your workouts and keep your body energized.

    Featured Ingredients

    Caffeine – Caffeine is a natural stimulant that increases energy production for increased athletic capacity and improved metabolism. Caffeine has been shown to help subjects lose weight, workout harder and longer, and increase intensity and number of reps.

    Taurine – Taurine is an amino acid that helps to lower cortisol levels – reducing anxiety and stress so you can intensify your focus on working out and achieving your goals. Taurine also helps to increase energy levels and burn fat stores.

    Beta-Alanine – Beta-Alanine is a beta-amino acid that raises muscle carnosine levels to increase the amount of work you can perform at high intensities. Beta-alanine is a hybrid of l-glycine and GABA, producing a caffeine-like response for higher energy levels.

    L-Leucine – Leucine is the most abundant of the three branched chain amino acids in muscles and is burned by muscles as fuel. Intake of leucine stimulates protein synthesis to build muscle.
