Aiming to be brawny? If yes, whey protein isolate, when used as an adjunct to diet, can be a great option for you. Bodybuilders and athletes benefit from taking whey as it helps to repair and build lean muscles. Protein also has multiple health benefits. Although, various forms of proteins can help to build muscles, whey protein isolate is a natural and safe form.

But what is whey protein isolate? And, more importantly, should you use it? Let’s understand more about whey protein isolate.

What is Whey Protein Isolate?

A whey protein isolate is a food ingredient and dietary supplement obtained after separating different whey constituents. Whey is a liquid product that is obtained as a by-product while making cheese. The liquid undergoes various processing steps before it forms whey. Moreover, there are three different types of whey: whey concentrate, whey isolate, and whey hydrolysate.

All these different types differ in their composition, especially the protein concentration. Whey protein isolate has a higher percentage of pure protein as compared to other types. It is also almost carbohydrate, cholesterol, fat, and lactose-free.

Proteins in whey isolate protein are highly bioavailable and contain a high amount of branched amino acids (BCAAs). The concentration of BCAAs is high in muscles, which helps to boost protein synthesis.

Why Is Whey Protein Isolate Essential

When muscle buiding is your goal whey protein isolate helps in the following ways –

Supports Muscle Building

Muscles are highly made up of proteins, which are a collection of amino-acid molecules. For optimal muscle growth, they require 20 different amino acids. Out of those 20 amino acids, 11 are non-essential, meaning they are produced by your body. While the remaining nine have to be obtained through diet and are thus known as essential amino acids

Whey protein contains all 9 essential amino acids. It also has an extra high dose of the amino acid, leucine, which effectively stimulates muscle protein synthesis and helps build more muscle mass.

Whey protein isolate is the purest source of protein. It includes protein at a concentration of 90% or higher, which is rarely available in other food sources. In addition, whey protein isolate also has the highest amount of BCAAs. These amino acids help in building muscle tissue, maintaining muscle health, and preventing catabolic activities, such as high-intensity resistance training exercises.

Boosts the Production of Anabolic Hormones

Whey isolate protein, when taken along with exercise, triggers the release of anabolic hormones that are required for muscle growth. It is thus a good source of go-to protein during the post and pre-workout window.

Helps to Meet Your Protein Requirements

According to the American College of Sports Medicine, you need 0.5 – 1 g of protein/ your bodyweight if you want to increase your lean muscle mass. Consuming an adequate quantity of protein may not always be possible through the diet. Whey protein isolate can come handy in such cases. It has a high quantity of good quality proteins that supports your goal of muscle mass gain.

  • Always consult a doctor before consuming whey protein isolate if you have a chronic disorder or are on medications.
  • Side-effects of a high dose include cramps, nausea, diarrhea, fatigue

How to Take Whey Protein Isolate?

The majority of whey protein isolates are in powder form. Read the instructions on the packing for serving size. Add one scoop of powder to almost 200 ml of milk or water. Blend it well for 30-45 seconds. You can take it once or twice a day.

If you aim for building muscles, consuming adequate energy and protein is as important as doing exercises. Whey protein isolate provides an adequate amount of high-quality protein needed by your body. So, now you no longer depend only on dietary sources for fulfilling the protein need.

Carbs in whey protein isolate provide energy that is important for strength and stamina during the workout. It also helps to build, maintain, and repair lean muscles.
