Among all the nutrients that we nourish our body, Protein is probably the most necessary for training people. We all constantly hear about the protein: how much, how often, which one.
Although you may have heard of whey protein, you may not have known hydrolyzed protein, which is obtained by hydrolysis or pre-fermentation, pure protein in a mixture amino acids and smaller proteins.

Which protein is better to buy regular whey or hydrolyzed?
Some supplement manufacturers claim that pre fermentation increases the biological value, thus increasing muscle protein synthesis. Because of its alleged hydrolyzed protein can cost 30-200% more their usual counterparts.
But is hydrolyzed protein worth the money? Studies give the exact answer is no.
How fast is whey protein digested?
Whey is a “fast” protein, it is quickly digested and absorbed, and its amino acids quickly enter the bloodstream, and then into the muscles. It was known, and Byrd recently confirmed it again and Colleagues.
Basically, this study found that the number of amino acids are higher when a person consumes whey (“fast” protein), as opposed to casein (“slow” protein). A high concentration of basic amino acids is associated with a higher muscle protein synthesis both at rest (“FED”) and after exercises (“EX-FED”).
This is one of the reasons why protein is better to eat before training, not after; peak amino acids occur at the time when the blood flows as much as possible to the loaded muscles, directing, thus building blocks to where they most necessary.
Hydrolyzed protein is digested faster than serum?
Protein is not alone responsible for the biological value that important in the question of whether to choose hydrolyzed protein. Though, Coopman and colleagues showed that amino acid levels are significantly higher in “fast” protein, differences between pre fermented (hydrolyzed) protein and whole protein were insignificant.
So just being “fast” protein is not enough. When compared hydrolyzed whey and casein, then Tang and colleagues showed something very important in the differences between hydrolyzed whey and casein:
Compare with the differences obtained by Pennings and colleagues:
These studies have shown that non-hydrolyzed serum is about twice as good as casein. There are some differences between hydrolyzed whey and casein. Thus pre-fermented whey is not better than whole whey.
Is hydrolyzed whey superior to whole proteins?
The answer we found in these studies is “No.” Coopman and Petting showed that hydrolysis of casein makes it “fast” protein, but does not improve the ability to stimulate protein synthesis. Studies by Tang and Petting show that serum is doubled better than casein, whether it is hydrolyzed or not.
Is there really something supernatural in serum? Overall these the data says yes. In other words, whey is better than whole casein, a “slow” protein, and better than hydrolyzed casein, a “fast” protein.
Whole whey is already a “fast” protein, so much more can hydrolysis make it fast? Not by how much. Should to pay more money for pre-fermented protein? Our conclusion regarding hydrolyzed protein: not believe annoying ads – whey remains the only the best.
