The most important time to take whey protein powder is within the first half-hour, post-workout. Of course you will be taking it throughout the day, but this is the absolute sweet-spot when it can do the most good.
In fact, the sooner you take it after your workout, the better. To understand why this is, we will look at the science behind what happens to our bodies when we work out.
Working out damages the muscles.
Don’t be alarmed, this is normal and healthy. When we work out, the fibers in our muscles suffer microscopic tears. When we rest, our muscles recover from this exercise induced damage, and grow stronger.
To do this repairing, the muscles need protein. Taking whey protein post-workout, just helps to ensure that this protein is on-hand to start the recovery as soon as possible for optimum results. Whey protein supplements are also absorbed by the body much faster than if consumed through food.
