Whey protein is a complete source of protein used for muscle growth. It is the liquid by product of cheese, sold as a dietary supplement. Earlier, whey protein was discarded by cheese and dairy product manufacturers as a waste product, but now it’s being used by body builders as a dietary supplement. Normally, milk has two types of protein-a) casein and b) whey. Whey protein can be separated from the casein in milk or extracted as a by-product of cheese making.
Whey protein significantly reduces the need for carbohydrates and fats in excess, it is a main diet component of people who are looking to build up lean muscle mass and muscle growth. If you’ve come across body builders and weight lifters with beefed up bodies, then there’s a possibility that they have a good intake of whey protein.
Since whey protein is a by-product of animals, it produces amino acids that your body cannot produce itself. Hence, it promotes various vital body functions, including skin and connective tissue growth, and body resistance. Contrary to popular belief, whey protein does not contain just protein, but also a composition of lactose, fats and minerals which are helpful for muscle growth and body metabolism.
Which is the Best Type of Whey Protein?
There are basically three different types of whey protein which undergo different degrees of filtering.
Whey protein concentrate (WPC) is the cheapest of all forms as it undergoes minimum processing. WPC follows a micro-filtration process, which retains around 70 to 80% of protein.
