To understand clearly what whey protein is, one needs to know what whey in its self is. Whey is an essential liquid material, created as a by-product in cheese production from cow’s milk. Whey protein is therefore a globular protein mixture isolated from whey. That is to say, whey is simply a raw material eventually used in making up whey protein powder. Whey protein powder is a compound of globular proteins, it comprises of four major protein fractions, immunoglobulins, serum albumin, alpha lactalbumin, and beta lactoglobumin.
There are a number of different types of whey proteins out there. However, there exist only three major types: Isolate, hydrolysate, and concentrate. Typically, whey protein comes in three major forms, with concentrate (WPC) – having relatively low but significant fat and cholesterol, this form has the highest level of bioactive compounds as well as carbohydrates in lactose form. The second form is the Isolates; they are well processed to remove lactose and fats, they have very low bioactive compounds. The last form is the hydrolysates; they are partially hydrolyzed and pre-digested to ease the process of metabolism. Unfortunately, they are more expensive.
Benefits of Whey Proteins
Whey protein is produced, marketed and taken as a dietary supplement. It is highly attributed to be an alternative medicine in the health sector. It is important in many areas including bodybuilding, muscle protein synthesis as well as the growth of muscle tissues; this is due to its abundance of amino acids e.g. Leucine. In addition, it is essential in wound healing, type 2 diabetes, among others. Finally, whey protein is effective on reducing risks of cancer, and heart disease. However, it is important to note that it has some digestive issues such as bloating, tiredness, irritability, gas, fatigue and cramps. These only occur in a minority of people however.

Again whey protein is a by-product of cheese manufacture and it is a very rich source of many amino acids. Since this supplement has low levels of carbohydrate, using this as a low-carb snack on a regular basis, will help you lose weight. It is also rich in antioxidants that help build your immune system.
Since it is a fast digesting protein, it is perfect for consumption before and after workout. The amino acids promote muscle building and prevent muscle breakdown and initiate protein synthesis. The most beneficial aspect of whey protein is that it is known to have anti cancerous properties.
Apart from fulfilling your protein requirements for the day, whey protein has several other benefits. Add it to your diet for an overall improvement in health and well being.
