What You Need to Know about Isolate Whey

A whey protein isolate (often whey isolate) is a dietary supplement and food ingredient created by separating components from milk. Whey is the watery part of milk that is separated from the curd, especially in the cheese-making process. Whey protein isolate is a complete protein and the purest form of whey. Using it in your diet reduces tissue damage and increases performance.

Other benefits include:

  • Essential amino acids: Whey protein contains all of the essential amino acids that your body needs to repair muscle after a workout.
  • Easily digested: Whey protein isolate can be easily digested by your body. This protein will be absorbed and processed quickly.
  • Increases muscle mass and repair: Muscle mass is built with the generation of lean tissues, and whey isolate protein significantly aids in repairing those post-workout muscle strains. Taking whey isolate protein supplements an hour before and after workout sessions has been proven to increase muscle size and thus vigor and strength.

Whey protein concentrate has a protein content of around 80%, while the protein content of whey protein isolate is 90%. This is because whey protein isolate undergoes a process called cross-flow microfiltration, which separates the protein from fat, cholesterol, and lactose, resulting in a purer protein as the end product. In addition, Performance Inspired Isolate Whey has 3g of added L-glutamine* (not counted in the 25g protein amount) to help preserve muscle tissue.

Which should you choose: whey protein concentrate or whey protein isolate? People debate which is better, and everyone has a preference. There is no outright winner, and the whey you choose depends on your personal nutritional goals and on your lactose tolerance. Whey protein isolate has a higher protein content and is lower in carbohydrates, lactose, and fat. But it is typically more expensive due to the additional manufacturing process it undergoes. If your goal is to keep your body fat low, or if you’re very lactose intolerant, then WPI may be the better choice.

Whey protein in general is one of the best types of proteins you can consume for muscle building because it contains essential and branched-chain amino acids. By consuming whey protein before or after your workout, you can raise the amount of amino acids available in your body for the muscle growth process, also known as muscle protein synthesis. Whey protein has one of the best protein ratings in terms of amino acid composition and digestibility.

*Our Isolate Whey protein supports your Keto Diet with low carbs and sugar. What is a Keto Diet? A Keto—short for ketogenic—Diet is a low-carb diet in which the body produces ketones in the liver to use as energy in lieu of carbohydrates. In a Keto Diet, 80% of your diet is comprised of fat, 15% is protein, and only 5% should come from carbs. For someone on a 1,500-calorie diet, that translates to 19 grams of carbohydrates per day, which is less than you will find in a medium apple.

**L-glutamine is the most abundant amino acid in the bloodstream, and it makes up 30-35 percent of the amino acid nitrogen in your blood. It’s actually known as a conditionally essential amino acid because your body uses it in such large amounts.
