Whey Protein Concentrate vs. Isolate vs. Hydrolyzed

whey protein concentrate

In today’s sports and fitness market, whey protein is one of the most commonly suggested and used supplements. Many athletes use and suggest protein powder to achieve their daily protein requirements for muscle building and recovery.

One of the two primary proteins present in milk is whey protein. Fat, sugar, and protein make up the macro components of milk (whey and casein). In this article we will discuss about the diffrence of whey protein concentrate vs isolate vs hydrolyzed.

What is Whey Protein?

Milk is used to make whey. This milk is made up of two forms of protein: 80 percent casein and 20% whey. Heat and add enzymes to separate the protein from the liquid to separate these two from the milk. When dairy farmers manufacture cheese, this happens naturally.

When the protein is separated, it dries into a powder with the perfect ratio for a great whey protein shake foundation. Both proteins are classified as complete proteins because they include all nine essential amino acids, which are required for the production of all critical muscle-building leucines.

However, with so many different proteins on the market, how can you tell which ones are which? Whey Protein Concentrate, Whey Isolate, and Hydrolyzed Whey are the three most popular protein powders on the market today.

What is Whey Protein Concentrate?

Whey protein is a milk protein. It is filtered rather than cooked after the whey protein has been removed. Providing your muscles with a high-protein combination that is ultra-pure, ultra-refined, and strong. Whey Protein Concentrate is often regarded as the most popular, effective, and cost-efficient protein available today.


The amino acid profile of Whey Protein Concentrate is kept as pure and powerful as possible by filtering rather than heating it. This also means that it keeps its silky smooth texture when blended with water or milk. However, this is only found in high-quality whey protein smoothies.

Whey Protein Concentrate Nutritional Facts

When whey protein is extracted from milk and microfiltered, it preserves a high proportion of protein, which can vary from 30% at the lowest end of the quality spectrum to 80% at the highest end.

Most businesses use 80 percent, so you can be sure you’re getting the most out of each drink. It has a high protein content, yet it is also low in carbs and fat. See the table below for the nutritional information for the flavored Chocolate Whey Protein.

  • Serving 25 g (1 Scoop)
  • Protein: 19.2g
  • Carbohydrates: 2.4g
  • Fats: 1.6g
  • Calories: 101

What is Whey Protein Isolate?

Whey Protein Isolate is sometimes disregarded in the realm of sports nutrition, but don’t let that fool you. Whey Protein Isolate contains a lot of protein, much more than a concentrate. As previously indicated, whey protein concentrate comprises around 80% protein, whereas isolate includes approximately 90%.

Whey Protein Isolate is extremely pure and non-greasy despite being processed. Cross-flow microfiltration is used to separate whey protein isolate. It simply separates protein from fat, cholesterol, and lactose, yielding an extremely pure final product.

Whey Protein Isolate contains far less fat, cholesterol, carbs, lactose, and calories than any other protein shake available. Although not lactose-free, it is very low in lactose and is frequently advised for athletes who have trouble with dairy products.

Whey Protein Isolate Nutritional Facts

Whey Protein Isolate, like Whey Protein Concentrate, is exceptionally low in calories. Whey protein isolates are available in a variety of protein concentrations on the market. Because it is highly filtered, your body can absorb and assimilate it swiftly. Whey Chocolate Flavored Isolate Protein is described further down.

  • Per 25g Serving (1 Scoop)
  • Protein: 21.9g
  • Carbohydrates: 0.2g
  • Fats: 0.2g
  • Calories: 91

What is Hydrolyzed Whey Protein?

Whey that has been hydrolyzed has been subjected to heat, acid, or enzymes that break the bonds that keep amino acids together. This technique, according to protein makers, “pre-metabolizes” the protein, improving its bioavailability, making it more digestible, and increasing protein synthesis.

Whey Protein Hydrolyzed Nutritional Facts

Hydrolyzed Whey Protein is one of the highest-quality proteins available, and its cost reflects that. It’s in infant food, as well as a variety of sports and wellness supplements.

Recommended for people looking to increase muscular bulk rapidly. It’s ideal for weight-gain regimens, and you may have it as a rapid supply of protein first thing in the morning, before and after your workout.

  • Per 25g Serving (1 Scoop)
  • Protein: 23g
  • Carbohydrates: 1g
  • Fats: 0.5g
  • Calories: 100

What’s the Difference Between Each Type of Whey Protein Powder?

Microfiltration is used to filter the liquid sweet whey left behind after casein is released. Whey protein concentrate is the end product. Whey concentrate has 70-80 percent protein and is low in lactose, sugar, and fat.

A calorie-dense dietary supplement that takes a long time, perhaps hours, to be absorbed by the muscles. This entails a longer recovery period and worse long-term outcomes.

Some supplement companies stop there, flavoring the whey protein concentrate and selling it as a completed product. Ultrafiltration of the whey protein concentrate is the next stage in producing a wonderful type of whey protein.

Another detox that reduces carbohydrates and lipids while increasing protein intake. Ultrafiltration “isolates” the whey protein by removing the non-protein components.

Whey Protein Isolate is the result of this. This type of whey comprises 90% protein and includes less lactose, sugar, and fat, making it a more refined protein.

This is a different type of whey protein that you may buy from firms that cease making it here and add flavors. However, there is one more step that just a few businesses follow.

Hydrolyzed Whey Protein Isolate

Some companies take this process even further, converting whey protein isolate to whey protein hydrolyzate. Enzymes operating on whey protein isolate break the bonds that link amino acids together, causing this to happen.

Simply said, amino acids are split into smaller bits, resulting in shorter chains of di- and tripeptides, allowing the hydrolyzed whey protein to release the quickest and easiest protein to digest.

It’s essentially a pre-digestion procedure that permits hydrolyzed proteins to absorb considerably more quickly in the intestines, followed by whey protein isolates and concentrates. It’s also less difficult to digest for folks with sensitive stomachs.

What Type of Whey Protein Should I Use?

Whey protein is a popular element in nutritional supplements since it is made up of numerous fast-digesting proteins. Whey Isolate is processed differently from Whey Concentrate, resulting in a greater protein content, lower carbohydrate content, and lower fat content per serving.

However, these dietary changes are minor, and the consequences of the two forms of whey protein are mainly unknown. Whey isolation and hydrolysis might be a suitable option for people who want to keep their fat, carbohydrate, and lactose consumption under control, albeit this type of whey is generally more costly.

A slightly greater dose of whey concentrate can provide the same amount of protein as a whey isolate product while costing less. Whey concentrate has a lower protein content and a somewhat greater fat/carbohydrate content than other protein sources.

Isolate may be the best option if you are lactose intolerant or have other dietary limitations. Aside from that, most individuals benefit from some whey protein meals; nevertheless, the extra value of a better product does not always imply superior outcomes.

Whey protein, regardless of the form, is a high-quality protein that can help you meet your daily protein requirements.

Final Thoughts

Whey protein is made from a watery waste product of the cheese-making process. The liquid is then purified before being turned into a whey protein supplement.

The higher the protein level, the more processing there is. Whey concentrate comprises 29–89% protein, whereas isolate, a more refined product, provides over 90% protein.

Hydrolyzed proteins are broken down into smaller chains to help the body absorb them more quickly. The amount of protein in hydrolyzed whey is determined by how amino acid chains are broken down.
