Whey protein isolate

Whey protein is considered by many to be the ultimate supplier of protein to the human body. Many studies state that whey protein is among the highest and best quality of protein that is available. Whey protein is found to be one of the richest sources of   BCAAs which is a type of amino acid. These BCAAs are found to contain the largest known levels among any of the natural food sources.

Whey protein is also categorized as one of the two protein types which can be obtained from dairy products. The other type of protein is known as casein protein.
Whey protein is formed as a by-product when cow's milk is in the process of being turned into cheese. As the milk is being converted into cheese, a by-product called whey protein is formed. It has been established that no actual foods are found to contain whey protein as it is the result of a chemical process within the milk when cheese is being made. However whey protein can be found in various foods like protein powders, certain drinks and some protein bars. But there are many foods which contain very high quantities of protein. Some of the most common foods that have high levels of protein include chicken, turkey, lean red meats and fish. Lean red meats are found to contain about 20 percent of protein along with turkey, chicken and fish. Eggs are also high in protein and contain between 7 to 8 percent. Cheese contains between 10 to 30 percent of protein but is also found to be high in fat.

There are largely two main types of whey protein. These are known as whey protein concentrate and whey protein isolate. Whey protein concentrate is found to be low in fat, but is said to have the highest biological value. This is typically approximately 75% of pure protein simply by weight. Thus Whey protein isolate is said to be whey in the purest form. These whey protein isolates are processed such that all lactose and fat are removed. Typically the whey protein isolate is said to be approximately 90% of pure protein just by weight. There are different types of whey protein like nectar whey protein isolate, whey protein isolate powder etc. Now whey protein isolate is available in supplements too. These whey protein supplements are categorized broadly into 3 parts. These include whey protein isolate, whey protein blends and whey protein concentrates. The whey protein powders from the concentrates are found to be the cheapest. However they contain the largest quantities of lactose and fat.  Whey protein is said to be more superior to all the other available forms of protein. Whey protein provides the human body with the amino acid profile that is required for muscle strength, building, and recovery. Most bodybuilders and other professional athletes will usually be aware of the importance of them using these whey protein supplements to aid in increasing the strength, size, and speeding up of recovery times.

Whey protein gets absorbed very fast by the body and this will help to provide an individual with an energy boost. Thus whey protein can play a big part in a person’s nutrition plan post work out. In the post work put stage the body is normally in a catabolic state and will need a quick supply of protein. There are no documented whey protein isolate side effects. However there may be some people who are allergic to dairy products and will need to consult a doctor prior to taking any of the whey protein isolate or concentrate supplements. The better quality the product however, the higher is the price of the protein whey isolate.
