Whey protein is by far the most common form of protein used in post-workout supplements; this is for a number of reasons. Whey is actually milk protein which has been separated from the fat and sugars, purified, and dehydrated. It makes for an excellent recovery supplement because dairy proteins tend have a higher number of branched chain amino acids such as leucine and valine which are absorbed into the blood and transported to muscle tissue much faster than other amino acids.
The other favourable quality of whey protein which makes it a desirable post workout supplement is that it a complete protein. This means that all the amino acids that are essential for good health are present in this protein, as it is an animal protein.
It is well established that supplemental protein is of the same efficacy as if it were obtained from traditional food sources. This makes whey protein powders a reliable and time saving source of protein when you simply don’t have time to prepare whole meals. It cannot be stressed enough how important it is to receive adequate amounts of protein after exercising to be sure you are able to maintain the muscles anabolic state. Should the pools of amino acids drop too low in the muscle, it will go into a catabolic state which can hurt big gains in volume and strength. Whey protein is without a doubt the ideal source for non-vegan gym goers everywhere.
