Hydrolysed Whey Protein Isolate

Nutrients Direct’s Hydrolysed Whey Protein Isolate is one of the fastest absorbing proteins on the market. Hydroysed Whey Protein Isolate is produced by treating purified whey protein with enzymes which make the product pre-digested so that it can be quickly absorbed by the body.

Hydrolysed Whey Protein Isolate contains high levels of essential amino acids (EAAs), branched chain amino acids (BCAA) and highly bioactive peptide fractions that help with muscle growth through rapid absorption. This protein source is also easier on the digestive system as it is the quickest form of whey protein to digest.

Discover If Hydrolysed Whey Protein Isolate (HWPI) Could Benefit You!

When you have many whey protein supplements to choose from, it can be rather difficult to make a decision. If you are a beginner where supplements are concerned, we can certainly recommend taking a look at Hydrolysed Whey Protein Isolate. To find out more about this protein supplement, and to determine if it is the right choice for your, please read our information below.

What Is Hydrolysed Whey Protein?

Hydrolysed whey is considered to be the purest form of whey protein available on the market today. It is made with a manufacturing process called hydrolysis. During this manufacturing process, protein chains inside regular whey protein are broken down into smaller protein fragments. The result is a pre-digest form of whey protein, which is easier to absorb for the body.

The main difference between hydrolysed whey protein and other whey variants on the market is the absorption and digestion rate. Compared to other whey proteins, hydrolysed whey has a much quicker rate of absorption and digestion, subsequently making it most suitable for athletes looking for a very quick protein fix.

What Are the Specific Benefits of Hydrolysed Whey?

One of the major benefits of hydrolysed whey is it superior bioavailability compared to other protein supplements, making it easier to digest and absorb. The protein content in hydrolysed whey is also substantial with a minimum dry protein content of 85%.

Most athletes use hydrolysed whey after their training, because the supplement can deliver a quick burst of amino acids and protein in a fast and efficient manner. The fast supply of these substances can promote processes such as muscle repair, growth and recovery. Let us look into each benefit with a little more detail to determine if it could benefit your training.

Muscle Recovery

Timing is everything for athletes who want to promote muscle recovery, since their protein-rich shake must be consumed at the right time in order to be useful. Then you also need to take into consideration that different types of protein supplements will be digested and absorbed at a different speed.

Athletes with a faster metabolism tend to benefit more from a slow-release protein such as casein, opposed to whey which absorbs quite quickly. However, athletes with slower or regular metabolisms will benefit more from a fast-release protein such as whey.

When you want to ensure your muscles get the right nutrients for recovery quickly after your training, whey supplements will be recommended. Hydrolysed whey, and other whey supplements, are characterised by their fast absorption and easier digestion, so this will be your best choice if you want quick nutrients post-workout.

Muscle Growth

There has been a tremendous amount of research into the relationship between whey and muscle building. Evidence obtained from these studies seem to back up the claim that whey is an excellent muscle builder for several reasons. The fast absorption rate of nutrients definitely contributes to the muscle building qualities of whey. Of course, the nutrients inside whey are the substances that actually do the work.

When you consume a whey supplement, your body will get a good amount of amino acids. These amino acids are the building blocks for all proteins in the body, including muscle protein. Once amino acids obtained through whey have hit your bloodstream, they are immediately transported to muscle tissue. Inside the muscle tissue, these amino acids will start a reaction called protein synthesis.

The specific types of amino acids present in whey supplements, more specifically the branched chain amino acids, also play a role in the effectiveness of whey supplements for muscle building. One specific branched chain amino acid, leucine, is especially beneficial, because studies have suggested that this amino acid is pretty much the fuel for muscle protein synthesis.

During a study executed in 1997, researchers noted that test subjects consuming a whey supplement were able to increase protein synthesis in the body by 70%. Test subjects using a casein supplement still enjoyed increased protein synthesis, but their increase only reached 30%.

In addition to the study executed in 1997, there has been a more recent study looking at the effects of whey supplements on muscle growth. Over the course of the fourteen-week study, researchers found that the use of whey supplements increased the muscle growth of test subjects with a whopping 25%. The other group of test subjects, who were consuming carbohydrates, did not get any change in muscle mass whatsoever.

Weight Loss

Whey supplements can be useful for weight loss as well as muscle building. A study executed by the USDA reported that test subjects, which consisted of both men and women, lost five pounds of fat over a period of twelve weeks. During these twelve weeks, test subjects were supplemented with whey shakes. There was also another test group who did not experience any changes in body composition. However, this test group was using a soy protein supplement.


When you understand how protein supplements work, you can get a considerable amount of benefit from them. It is never about the highest percentage of protein, nor is it about the fastest absorption rate. At the end of the day, the most effective supplement for you will match your metabolism, training and nutrition.

To get a better idea about supplements suitable for your training goals, we recommend having a look at the most common protein supplements, more specifically casein and whey. Athletes can combine these supplements and use each one at the recommended time to benefit from both a fast release of protein and a prolonged release of protein. However, before you choose a specific set of supplements, be sure you do not exceed the daily recommended dose of protein.

Hydrolysed whey protein isolate can contribute to numerous fitness goals, but athletes must not forget the main purpose of this excellent supplement, more specifically adding more quality protein in the diet of an athlete. When an athlete subjects his or her body to rigorous exercise, the body will need more protein to repair muscle and keep the cells functioning correctly. While these functions are directly related to muscle growth, muscle repair and muscle recovery, it is worth mentioning here. If you are subjecting yourself to rigorous exercise, but cannot incorporate enough protein in your diet to match the demand, Hydrolysed Whey Protein Isolate may be a good supplement choice for you.

If your diet is low in protein, but your exercise is rigorous, it may still be needed to change your diet and incorporate more sources of protein. While a protein supplement can provide your body with the essential proteins it needs, it is still necessary to understand and apply the primary functions of protein-rich foods within your diet. If you do more exercise, it is usually required to increase your calories to meet your body’s energy demand as well. Therefore, do not only look at your protein intake, but at your nutrient intake in its entirety. However, if you have little experience or knowledge about the nutrients your body needs, you can also ask a nutritionist or your local doctor for advice.
