Whey Protein. Whey proteins account for 20% of the protein in milk. Whey protein is a by-product in the production of cheese. Initially thought of as just a waste product, whey protein is now the most popular protein supplementation protein source. It has a very high BV rating, and is rich in the muscle-building amino acids leucine, isoleucine, and valine. Whey protein is a fast digesting protein source, and isn’t filling. Whey protein is also low in glutamine and arginine.
Whey Isolate. Whey isolate is a more expensive version of whey protein. It is a higher quality protein source with a higher biological value (BV), and contains less fat and lactose per serving thenwhey concentrate. Whey isolate generally contains 90 to 98& protein, while whey concentratecontains 70 to 85% protein.
Whey Concentrate. Whey concentrate is a more cost-effective member of the whey family. It requires less processing time, but also contains more fat and lactose. Whey concentrate is 70 to 85% protein.
Whey Protein Blends. Whey protein blends are specialized protein formulas that contain both whey Isolates and whey concentrates. Whey protein blends are generally more cost effective then whey isolate, and have a higher protein percentage ratio then whey concentrates.
Casein Protein. Casein proteins account for 80% of the protein in milk. Casein protein is a slow digesting protein that is isolated from milk. It is 92% protein, and has a very “thick” taste. Because of this, it is a very popular protein in weight gainers. Casein protein, although it has a lower BV value then whey, is more efficiently used to build muscle. Because casein protein is used by the body to build muscle, and less is used as a energy source, casein supplementation encourages the body to use carbs and stored fat for energy. Casein is also very high in the popular bodybuilding supplement glutamine.
Egg Albumin. Egg albumin is the egg white. It is popular in bodybuilding circles because of a higher essential to non-essential amino acid ratio, and because egg whites contain less cholesterol then egg yolks. Eggs are often considered the king of natural food proteins because of their high essential amino acids levels. Egg protein is the best alternative for those that are lactose intolerant.
Soy Protein. Soy protein is high quality, but not as efficient as milk or casein protein, It is a fast digesting protein source that has an average amino acid profile. Because of this, it is not the most desirable protein source for those looking to build muscle.
Goat Milk Protein. No other protein source has a higher bioavailability then goat milk protein. In addition, goat milk protein is extremely high in BCAA and is 100% lactose free. Its BV rating of 104 is superior to most foods, including eggs, which have a 100 BV.
Wheat Protein. Wheat protein is a healthy and natural alternative to dairy and egg-based proteins. It is lactose and cholesterol free, and is perfect for vegetarian bodybuilders and athletes. Wheat protein is also very high is glutamic acid.
Pea Protein. Pea protein is a 100% gluten free protein source that is a great alternative for vegetarians. As with wheat protein, pea protein is lactose free and does not contain any cholesterol. It is very easy to digest and is rich in amino acids.
Complete Milk Protein. Complete milk protein is the dried protein from milk, with the carbs and fat removed. Milk protein is nutritious, and contains calcium and high levels of other vitamins and minerals. Complete milk protein contains both whey and casein proteins.
