Whey Protein Concentrate is derived from milk and is rapidly absorbed into the bloodstream which makes it ideal after a workout and upon waking in the morning. Proteins are extracted from whey by micro-filtration, cross-flow micro-filtration and ion exchange. These processes preserve the integrity of the protein which yields a high-quality, low-lactose, low-fat protein source. Whey protein concentrate contains roughly 75% to 80% protein. It’s much more economical than whey isolate because the process of removing most fat and carbs is relatively inexpensive. Whey protein contains the highest concentration (23-25%) of branched chain amino acids (BCAA’s) of any single protein source. This BCAA content is important because BCAAs are an integral part of muscle metabolism and are the first aminos sacrificed during muscle catabolism.
