Whey protein is attractive to athletes largely because it’s an excellent source of Branched Chain Amino Acids (BCAAs). An analysis of 25 studies published in the journal Current Opinion in Clinical Nutrition & Metabolic Care suggests that whey has a lot more to offer above and beyond supporting muscle protein synthesis. Researchers believe that the bioactive microfractions found in whey might help lower blood glucose and insulin levels.

True Strength Moment: Contrary to what you might have heard, there is no single best protein to meet every need. There are many types because active adults are striving to meet such a wide range of goals. Lactoferrin, immunoglobulins and lactalbumin can be altered by processing. Because whey concentrate is closer to its natural state than isolates or peptides, it’s a great source for these bioactive compounds. So if your focus is recovery and immune system health, try a whey protein that contains a significant amount of concentrate.
