Any protein can be hydrolyzed, which means broken into smaller pieces or semi-digested. Soy, whey and collagen are commonly hydrolyzed proteins, which entails breaking them up into smaller peptides and making them far quicker absorbing protein sources. Unfortunately, hydrolyzed proteins taste like utter horror, so they are rarely used in protein formulations in any major volume. Hydrolyzed proteins provide one huge benefit over standard undigested proteins since hydrolyzed proteins absorb much more quickly and hit the blood stream faster than any other form of protein. This is a good benefit for an intra-workout drink and immediately after working out to replenish your protein supply. Often, you will find hydrolyzed proteins being sold as amino acids, but you should stay away from such formulas, since hydrolyzed proteins are not exactly the same as free form amino acids. Hydrolyzed proteins usually form large polypeptides, which are faster absorbing than straight protein but still not the same as a mix of free form amino acids. Still, post workout hydrolyzed proteins offer a good way to slam some serious anabolic building blocks right into your muscle.
