Prozis Real Whey Isolate, the review

Analysis of Prozis Sport's Real Whey Isolate supplement

After we published the analysis of the new Real Whey in September, there were many requests for an evaluation of this version as well.

As the name implies, it is a Whey protein, but unlike the original Real Whey, this version is composed only of Isolated Whey.

In other words, a better, and also more expensive, variant of whey protein.

If you want to know more about Whey protein and its different types, take a look at our comprehensive guide this page.

The review of Prozis Real Whey was very positive as you can see here. Does the Isolated version follow the same path or just use the same name?

We can start by saying that yes, the Real Whey Isolate it is also an excellent quality protein as you will be able to confirm in this analysis.


We have a partnership with the Prozis brand.

That said, this partnership does not influence the reviews made on the site, as we limit ourselves to evaluating the facts contained in each product's nutritional table, aminogram and ingredients.

That is, if the product is bad, it is bad. But if it is good, as is the case, then it will be classified as such. Impartiality is the priority in all reviews.

A good example of this is the Whey Prime.

This partnership allows us to have some benefits not only for us but also for those who visit the site.

Until the 13th of this month, when you use the code GVIRTUAL at checkout, you get a direct discount of 10% on your order here, and you also receive a shaker and 3 Zero Snack protein bars on orders over 25?.

This partnership no longer exists, this information being only a reference, and the analysis, obviously, remains the same.


In the Real Whey Concentrate analysis we put the data for the flavored and unflavored version.

This is because there was a difference, which, although not very significant, was there. Both nutritionally and in terms of price.

We're not going to do it with Real Whey Isolate.

This is because it is not worth it. The differences don't justify it, as they are incredibly close, so we're going to take a different approach.

We will make small references when necessary, but also small comparisons with the concentrated version to know the differences between them.

That said, we opted to look at the purest version, ie, flavorless or otherwise known as natural.

The ingredients are simple.

Isolated Whey and an emulsifier. Only.

In flavored versions you will find a few more, but few more.

In the case of strawberry flavor, this supplement is composed of 98% of Isolated Whey, where the remaining 2% is a combination of flavourings, colorings, etc. The usual ingredients used in this type of products to give the desired flavor to the shake.

That is, no tricks or spells. Just the essentials.

Nutritional value

Now that you know the ingredients used, the nutritional values for the flavorless version are below.

Dose / 25g












Looking at the table, what is immediately obvious is the protein content of this supplement.

THE Real Whey Isolate is made up of 94% of pure protein, an amazing value.

As if that wasn't enough, it is fat-free and carbohydrate levels are at 2.5%.

As you know these numbers refer to the natural/unflavored variant, but if you opt for the strawberry flavor the differences are minimal.

In the case of protein, the value drops to 93%, while carbohydrates rise to 3.5%.

Yes, in both cases the difference is 1%. Only 1%.

How does it compare to the concentrated version?

  • Protein. It has 10.6% more compared to the unflavored version of Real Whey Concentrate.
  • Carbohydrates. Here the difference is minimal, with the concentrated version presenting more 1.5%.
  • Fats. Real Whey concentrate has 7.5% of fat. Isolate as you have seen is grease free.

Therefore, the ingredients are approved and the nutritional value is excellent. But we still lack some things.


The aminogram is where often protein supplements that look promising actually turn out to be a letdown.

It's not the case.

You can consult the complete aminogram of Real Whey Isolate here.

How do you know the value of BCAA's is an excellent way to assess the quality of a Whey protein supplement.

This supplement for every 100g in the unflavored version has a concentration of 21.9% of BCAA's.

Each shake contains 5.47g of this combination of essential amino acids.

What does this mean? Is it good or is it bad?

It's very good, and nothing like a comparison with other proteins to confirm it.


Real Whey Isolate

Real Whey

ISO 100 Dymatize


Scitec Isogreat

ON Gold Standard









So far we haven't evaluated many exclusively isolated protein supplements.

But we've already evaluated some.

As you can see in the table, only the ISO: PRO 97 from Myprotein gets an equivalent amount.

We've also included Real Whey in the concentrated version to see the difference between them.

In addition, the ISO 100 Dymatize and Isogreat from Scitec Nutrition are two examples of isolated proteins. Isogreat is still approaching, but the Dymatize supplement has clearly lower values.

Finally, the Gold Standard from Optimum Nutrition despite not being an exclusively isolated protein, it is considered by many as one of the best proteins on the market. It is significantly behind Real Whey Isolate.

Therefore, at a nutritional level, we are dealing with a top protein. It only needs an assessment to know what level it is in in general.

Real Whey Isolate is only available in two sizes. 1kg and 2kg.

These are the current values, which are always subject to change, for the unflavored version of this supplement on the Prozis website.

We start by saying that the price difference between the flavorless and the flavored version is really low.

Are we talking about a difference of 1? in the case of the size of 1kg and 1.6? in 2kg format.

That said, the price is really good for a Whey Isolate supplement. Especially when this Isolated Whey has this quality.

Each shake will cost 0.60? if you choose the size of 1kg or 0.48? in the 2kg variant.

Let's again put the numbers in perspective with other supplements.

The supplements chosen for the price comparison were the same ones used for the quality assessment.

As you saw above, only one supplement (ISO: PRO 97) faced Real Whey Isolate in terms of quality, and only another came close (Scitec Isogreat).

When it comes to price, Prozis Sport managed to put an extremely attractive value considering that we are talking about an exclusively isolated protein, and leave these two supplements (much) behind.

Furthermore, it is interesting to look and see that although Real Whey Isolate is much superior to Gold Standard from Optimum Nutrition, it costs much more, despite offering much less.

Compared to the concentrated version the difference is 0.48?. An obviously significant difference, but expected.

For an exclusively isolated whey protein supplement, this is a very good price.

What is the cost per 100g of protein?

The cost per 100g of protein is the calculation that tells you how much you will pay for 100g of pure protein, not for 100g of supplement. Example. Unflavored Real Whey Isolate for every 100g has 94g of protein, meaning you need 106.38g of Real Whey Isolate to get 100g of real protein. This is usually the most accurate and reliable method of calculating the cost of a protein, except in cases of aminospiking.

THE Real Whey Isolate is the best choice in terms of quality/price in Whey protein supplements?

Do not.

This title belongs to Real Whey Concentrate and the Impact Whey.

But if what you are looking for is an Isolated Whey then you will hardly find a superior option.

Here's an excellent bet that doesn't sacrifice quality to get a good price. In fact, it combines both in an exemplary way.

  1. This type of analysis without an independent laboratory analysis is worthless, as it can only contain 10g of protein, as with Spanish brands, there is not the slightest control over it and to know what you buy, just send the product to laboratory analysis, because the manufacturer can even put on the 99g protein label that there is no entity that will control this.


      Rui, it is very explicit at the beginning of the analysis that what we do with all products is to evaluate the facts provided at a public and official level by the brands.

      1. My Protein, in this matter, offers more guarantees about its quality, as it is heavily analyzed by LabDoor.
        Virtual Gym: by the way, what do you think of this lab?

      2. The point here is that a brand like ON is sure that what they put on the label is what the product contains. I don't know about other brands. For example. it has already been said that brands like Scitec are quite dubious.


          Why is ON a certainty and the others are not?

          By the way, if you check the site of the previous comment (Labdoor) you will see that this is not what happens.

        2. When it comes to protein, there are many other trusted brands besides ON, I spoke of ON as I could have spoken of any other brand. I prefer to buy a protein ON, Reflex, MyProtein, etc than to buy other brands in which the quality control is not the same. For example, “it is said” that brands that use a “famous” production center in Hungary do not give the same guarantees regarding the quality of protein and its aminograms.

          Regarding Labdoor, I believe it is an exempt site, but there are certain criteria that I don't understand and for me what Labdoor says is not an absolute truth. For now, they have a special focus on exclusively American brands. High quality brands like Reflex are literally forgotten. Then there are criteria that are at least dubious. For example in the Pre-Workout category, I don't understand how Transparent Labs' PreSeries Bulk or Reflex's Muscle Bomb don't even make the list, when they're on par with Legion Pulse's best pre-workouts out there, with clinically tested doses. Then we see others in the top 10 that have less than half the doses of these in key ingredients (Beta-Alanine, Citrulline, etc.)


          It was just to not feed the myth that ON protein is reliable and others are not.

          There are certainly brands that “cheat” the label, but without rigorous independent laboratory analysis it is difficult to know that.

          Hence, we make it clear that we evaluate what the brand (all of them) declares, since it is impossible for us to carry out the type of analysis necessary to know if this information is correct.

          As for Labdoor, not knowing the details, it is normal that they focus on American brands since it is their main market.

          But regardless, any kind of site that reviews a product should be seen critically and not as absolute truth as you said (yes, us included! :) ).

        4. To do this, just send the products for laboratory analysis and ask for the % Protein present and check the ingredients if they contain aminospiking and remove these amino acids from the % Protein. For example, I already sent for analysis Spanish protein that marked on the label 92g protein and 2g hydrates and the reality was 56g protein and 40 carbs ????????????. But as the tuga people just want a low price, they don't mind buying gainers with protein labels????????????, the important thing is to be cheap.

        5. Simão, I'm based on several factors, but as I said before, this should be valid both for ON and for other so-called reliable brands.

          The first factor is that this protein has been in the top spot for over a decade.

          Being at the top gives great visibility and I don't believe that a brand like ON, whose best-known and most sold product is the Whey Gold Standard protein, "burns out" selling "cat in a poke".

          I'm also based on a lab test sent by a friend of mine about 2 years ago and in which more “brush less chick” what was on the label was what the test indicated.

          Note that I'm not a fan of ON, if you want to know protein is the only supplement I regularly consume from ON (I alternate with MyProtein and Reflex). For example I don't like any pre-workout supplement from ON and even in other segments I recognize the quality but I don't buy it for example. ON multivitamin, I think there are much better options.

        6. Vasco, if you really have that lab analysis, yes, it's a big quality factor. On the contrary, the fact that it has been the best seller for a good 10 years – no exaggeration – may not mean that much… I imagine that Prozis will take over the Portuguese and European markets soon and, I don't know why, whey from Prozis does not inspire great confidence in me.

        7. Simão, as long as UK does not leave the EU, I think it is unlikely that Myprotein will lose its primacy to any other brand, as it already has a large installed base of customers, has a lot of quality in its products and very aggressive prices.

          If you want me to tell you, I don't know the particular case of Prozis, but I know that there are brands that the product ends up being "the same" just by changing the label, To launch a protein or supplement brand, you put the product to be made in a of those factories that exist in Hungary or the Czech Republic where labor is cheaper and there is not much quality control. You go to a shopping center and SupplementsStore has a brand like that, you have the example of Zumub (ex. Zumbu and ex. Suplementos Online) which also has its brand. They have cheap products but I don't trust those products. As far as I've heard Scitec and Biotech use the same locations across Europe.

          ON, on the other hand, uses facilities in Ireland at European level. In Europe there is no place where there is more quality control than in the UK. That's why I like English brands like Reflex.

          In the USA you have a lot of “crap”, but you also have very good and reliable brands. It's a huge market.

  2. Well, My Protein seems to me to use good quality standards and, there it is, it is generally very well rated in the LabDoor rankings.

    But we all know what this fitness world is like: everyone is there to get rich… whatever the cost.

    The North American market has everything from organic whey and all 'green cows' to the biggest 'sludge'.

  3. Good Guys, excellent article as always, in the midst of these comments I had two doubts that I don't know if anyone can clarify… even so here goes:
    1st How much does a product review cost?
    2nd Where can we request such analyses?


  4. Having a high price does not guarantee quality. Yes, the cheaper ones may have less quality, but the Whey protein raw material is the same for all brands, you can buy a 20kg bag of glanbia, or something like that, it's the same one that ON uses, but only because it's ON you pay a little more. The ideal is to test everyone, price doesn't say anything, because the raw material of whey is not expensive.
