Protein is essential for lean muscle growth, maintaining muscle mass, raising metabolic rates and overall health. Protein powders shakes are an easy way to increase your daily protein intake, for both men and women. There are three main types of Protein Powder. Whey Protein Isolate, Whey Protein Concentrate and a blend of Whey Protein Isolate and Whey Protein Concentrate. Whey protein blends are the most popular protein shakes for women because they provide excellent quality products, at an affordable price. Whey Protein Isolate(WPI) is a protein powder that contains more protein and less fat & lactose per serving than any other protein powder derived from milk. Most whey protein isolates contain between 90-94% protein and have a fast digestion rate making them rapidly absorbed by the body. Whey Protein Isolate also contains high levels of Branched Chain Amino Acids (BCAAs) which may assist muscle recovery, making WPI a great choice both pre- and post-training. Whey Protein Concentrate (WPC) contains between 70-85% protein. It contains slightly higher amounts of carbohydrate & fat than Whey Protein Isolate but these nutrients are still at relatively low levels and the natural sugar (lactose) level in WPC makes it more palatable. "Whey Protein Concentrate powders are a great everyday protein, and because it is less expensive than WPI it is an extremely popular protein choice.It can be used post-training as well as taken throughout the day to increase overall protein intake. Whey Protein Isolate and Whey Protein Concentrate blends.(WPI/WPC) are made with both whey protein isolate and whey protein concentrate. Blends provide a balance between the rapid absorption of whey protein isolate and the relatively slower absorption of whey protein concentrate. Blends have an excellent profile of amino acids. They usually have less lactose, fat and carbs than whey protein concentrate alone, but more than whey protein isolate alone. They provide a balance in terms of nutrition and price. Whey protein blends are the most popular protein powders because they provide excellent quality products, at an affordable price.
