What is whey Protein

Whey is a complete protein, meaning it has all nine essential amino acids necessary for protein synthesis. Whey is a foundational supplement and supports a huge range of goals for both men and women. It’s fast-digesting and perfect for muscle building and fat loss in combination with a healthy diet and exercise. Whey is the liquid remaining after milk has been curdled and strained. It is a byproduct of the manufacture of cheese or casein and has several commercial uses. Sweet whey is a byproduct produced during the manufacture of rennet types of hard cheese, like Cheddar or Swiss cheese. Acid whey (also known as sour whey) is a byproduct produced during the making of acid types of dairy products, such as cottage cheese or strained yogurt.

Types of Whey Protein

There are three primary types of whey protein used in supplements.

These are as follows:

  • Whey Protein Concentrate (WPC) The percentage of protein available in WPC can vary from 30 to 90 percent; it depends on how concentrated it is. WPC also typically contains low levels of carbohydrates and fat.
  • Whey Protein Isolate (WPI) WPIs contain a higher percentage of protein than WPCs. Indeed, they are almost always at least 90 percent protein. This is because they’ve been further processed and thus have no fat or lactose.
  • Whey Protein Hydrolysate (WPH) WPH is a form of whey protein that has already experienced partial hydrolysis, a process needed for the body to absorb protein. Therefore, it’s considered “pre-digested” and is absorbed the fastest.
