What Types of Whey Protein are There?

Whey protein is produced from cow's milk. Whey protein is basically composed of four major protein fractions beta-lactoglobulin (approx. 65%), alpha lactalbumin (approx. 25%), serum albumin (approx 8%) and immunoglobulins. These are all combined to give whey protein the highest Biological Value of any known protein. Whey protein is one of best known body supplements, used widely for protein replenishment after exercise, for muscle building by sports persons and wrestlers, for weight loss, for controlling diabetes, for infant nutrition and immune support.

Whey Protein- Benefits and Side Effects

Types of Whey Protein

Whey protein falls into three categories:

  • Whey protein concentrate
  • Whey protein isolate
  • Whey protein blends
Whey Protein Concentrate <Pure Whey Protein Powder

Whey protein concentrate has a highest biological value. It is low in fat, and is about 75% pure protein by weight. Whey protein concentrate powder is considered to be the cheapest protein powder but with great benefits. It is referred as concentrate as it is a byproduct of the cheese manufacturing process. It has 29% to 89% protein by weight. It is low in fat and cholesterol. Since whey protein concentrate is the least processed type of whey protein, it has the highest bioactive compound levels, and carbohydrates in the form of milk sugars or lactose.

Whey Protein Isolate

Whey protein isolate is whey in its purest form. They are referred as isolates as they are processed to remove lactose and fat. Infact this isolate is about 90%+ pure protein by weight. Though such isolates have almost zero carbohydrates, lactose and fat, whey protein isolate powders have the most amount of protein per serving. This protein powder is the most easily-absorbed powder. The whey protein isolate is a must for most people looking to build up lean muscle mass. Whey protein isolates have the lactose and other impurities filtered from your product.

Whey Protein Blends

As the name suggests, they combine whey protein isolate and whey protein concentrate to make a high quality product. Whey Protein Blends are most popular type of whey protein powders. The product also consists of added amino acids, glutamine precursors and digestive enzymes which help in easy digestion and absorption
