Whey Protein Hydrolysate


  • Whey isolate or hydrolysate which is better?
  • Benefits of taking whey hydrolysate
  • Who should consider buying whey hydrolysate?

Fitness fever is ruling the era. If we open our social media, we see the celebs and fitness influencers are flaunting their bodies now and then. And we cannot deny the role of protein for that perfect physique.

If we talk about the ultimate premium quality whey protein, the first preference will always be – whey protein hydrolysate. But it digs a big hole into our pocket so, we are often confused that if it’s worth it or not.

So, today let us discuss some major role of Whey protein hydrolysate in our fitness journey.

What is whey protein hydrolysate?

By now we all know that whey is extracted from cow’s milk during the cheese-making process. It is known as pasteurization. This is done to eliminate some harmful bacteria present in milk.

This pasteurized milk is subjected to enzymes to separate whey from casein.

We can get three types of whey protein after this –

  • Whey concentrate
  • Whey isolate
  • Whey hydrolysate.

Now, you may wonder that if we are getting these three types from the same milk then why there are differences in their prices. The answer lies in the filtration process.

The more whey is filtered the concentration amount of protein is higher. Whey concentrate is the most calorie-dense form of whey protein.

So, it may not be the best alternative for people who are looking for some major weight loss.

After further purification of the extra carbohydrates and fats, we get the whey isolate. It contains almost 85% – 90% of protein.

Now with the additional heat, acids & enzymes, the amino acids are broken into very small pieces forming an ultimate concentrated form of protein. This is known as whey protein hydrolysate.

This pre-digestion makes hydrolysed protein more rapidly absorbed in the gut.

What is the difference between whey isolate and hydrolysate?

Whey protein isolate and whey protein hydrolysate both are the purest form of proteins. Both are slightly high on the price then what is the difference between these two. Let us check this out –

Whey protein isolate is extracted by a micro-filtration process to remove the maximum amount of carbs, fat and lactose present in the whey concentrate. So, it delivers a very high amount of pure protein to your body.

The benefits of isolate protein are –

  • It is lesser in fat and carbs. Aids weight loss and helps to gain lean muscle.
  • As lactose is almost non-existent in WPI, it is a good alternative for lactose-intolerant people.

Now, on the other hand, if we talk about whey protein hydrolysate, it undergoes another process called hydrolysis. Hydrolysis is made of two terms: hydro – water and lysis – to remove or unbind.

Whey Protein Hydrolysate vs Whey Protein Isolate

      In this process, whey protein has the addition of water into it helping the    protein chains to break down into many di/tripeptides making it digest faster and increase protein synthesis.

The advantage that hydrolysed whey offer is that it allows the amino acids of the protein to get absorbed in a body at a much higher rate compared to standard and complete proteins.

A study published in the Journal of Science and Medicine in Sport found that out of 28 athletes training twice per day, those who were taking hydrolysed whey recovered their power quickly than the athletes who were taking whey isolate.

So, we can conclude that –

  • Whey hydrolysate digests the fastest.
  • The most expensive form of whey.
  • Best for athletes and serious weight-lifters.


Whey Protein Hydrolysate benefits

  • The highest amount of protein absorption due to the hydrolysation (pre-digestion) process.
  • Consists of a high amount of important di and tri-peptide protein molecules, which play a key factor in protein synthesis aiding the muscle building process in the body.
  • Delivers more amino acids to your muscles.
  • Provides the fastest muscle recovery after an intense workout. And prepare it for further hustles.
  • Easy digestion system resulting zero bloating even for the people with severe digestive issues.
  • The highest degree of purification.
  • The price is higher than whey isolate or concentrate. But considering the amount of protein delivered to the muscle the price difference is justified.

Whey Protein Hydrolysate side effects

Whey protein is mostly safe to consume if taken appropriately. But continuous high doses can cause some major side effects such as-

Increased bowel movements





Reduced appetite



Another very common symptom seen in people taking too much whey protein is their urine becomes more acidic.

There is another very interesting controversy that is often heard– can whey protein cause Osteoporosis?

There is some concern that taking too much protein may cause calcium to leach from the bones and increase the risk of Osteoporosis.

But recent studies have shown that the body counters the effect of calcium loss by increasing calcium absorption from the gut.

Moreover, several studies have shown that elderly people, who are prone to osteoporosis should increase their protein intake to help maintain strong bones.

We should also keep in mind that as hydrolysed whey is the most filtered version of whey so it does lack a lot of vitamins and nutrients otherwise present in concentrated whey.

So, we should never use whey protein hydrolysate as a replacement for a meal.

A good body and mind are a result of a balanced and wholesome diet. And last but not least always keep your hydration in check. As we all know the role of water in removing toxins from the body.

Should you buy Whey Hydrolysate?


Whey protein Hydrolysate is the best option for athletes and sports enthusiast who do frequent intense training.

It recovers muscle damage and replenishes glycogen quickly so you can enjoy a full recovery soon and get prepare for the next training sessions.

Whey Protein Hydrolysate

For people who are aiming for weight loss, hydrolysed whey will benefit them post-workout to promote faster recovery with limited carbohydrates. It will help to maximize muscle-building with fewer calories.

So, if your goal is to increase your endurance and get the best effects of your high-intensity workouts then you should give it a shot.
