COMBAT 100% WHEY is a low-carb, high-protein, great-tasting protein supplement with minimal fat and low sodium that delivers fast digesting protein sources to build and maintain lean muscle mass. Combat 100% Whey combines two of the fastest digesting, most efficient, and cleanest protein sources available: Whey Protein Isolate and Whey protein Concentrate. Whey protein has the highest bioavailability among complete proteins (protein that contains a complete amino acid profile of all 9 essential amino acids) and also has the highest absorption rate among any other proteins. Whey protein isolate is a concentrated whey protein molecule "isolated" to remove any impurities such as fats, or sugars. This process, in turn, reduces the size of the molecule making it easier for the body to absorb and faster to digest. Additionally, Combat 100% Whey is low in sodium at only 65mg per serving. This can reduce the risk of excess water retention, further ensuring that the mass that you put on is the mass that you intended.
