True Protein’s Hydrolyzed Casein is derived from fresh skim milk. Hydrolyzed Casein is processed and extracted from casein protein, which is then specially prepared into an enzymatic hydrolysate.  This process provides the user with a rich source of short chain peptides and amino acids. 
                                           
Though Casein and Caseinate proteins are known for their slow digestion, Hydrolyzed Casein is still assimilated by the body very quickly.  Since it is a hydrostat the proteins are partially digested, up to 80% of the proteins bypass the
stomach and are absorbed directly through the small intestine. 
 
Studies have shown that Hydrolyzed Casein might be the best protein for building muscle and preventing catabolism (muscle breakdown).  Studies have also shown that hydrolyzed proteins with short chain amino acids (di and tri peptides) can increase IGF-1.
 
Hydrolyzed Casein is a great product, but again like many of our other hydrolyzed proteins, this product is extremely bitter.  When custom mixing your own blends, keep Hydrolyzed Casein below 25% for a good tasting product. We recommend you order your Hydrolyzed Casein separate to see how much the bitterness affects you.
