A Word About Proteins:

Before describing the details of our protein blend, a brief primer on the world of proteins may be helpful in order to gain a better understanding. Protein
In the simplest terms, proteins are biological molecules made of chains of amino acids. The body uses amino acids to produce its own proteins which act as structural components of muscle and other tissues. Proteins also participate in a wide range of essential processes that include enzyme function, cell growth, and cell signaling. Proteins can come from both animal and plant sources. Protein Concentrate
A form of supplemental protein powder made from a specific source, which contains 70-80% protein content. Protein concentrates are the most popular protein supplements on the market. Protein Isolate
A purified version of a protein concentrate powder that contains
90% or more protein.
