Post Workout Supplements are specifically designed to be taken in that crucial 45min window post training. This as we all know is the most important time to consume a Protein Shake. Post training the body is depleted of muscle glycogen and proteins. We need to replace this loss by consuming a Post Workout Protein Shake structured of carbs, protein, and fat. This stops muscle cannibalisation, and turns on the anabolic response starting muscle growth and recovery. Post Workout Supplements are a good choice post training when you need nutrients fast. As they are in liquid form and Whey Protein is highly bio-available Post Workout Shakes are often better than food post training due to their rapid absolution.
