Is Iso Whey Zero a good protein?
Biotech USA is a popular brand in gyms in Portugal, and among its various protein products, the Iso Whey Zero it is probably the best known.
But popular doesn't always mean good, and in this case, does this apply?
First of all, it is presented as a high quality Whey Isolate product, according to the official website, and is available in various sizes and flavors.
In addition to Whey Isolate, this supplement also has added amino acids, which is usually not good news.
So let's look at this supplement, starting with the most important, the ingredients.
This supplement has already changed its formula, and to collect the data from the current version, we used the information available on the official website of Biotech USA for Portugal.
Attention, in some stores you will still find the old version, or at least, the data from the previous version.
To consult the complete table of ingredients of this product click here.
The protein source of this supplement is called ?Iso Whey Zero Blend? and makes up 88% of the total product.
What is in there?
Within this mixture you will find Whey Protein Isolate, and then, a so-called amino acid complex. Basically a mixture, inside the mixture.
In this complex of amino acids are L-Arginine, L-Glutamine, L-Leucine, L-Isoleucine and L-Valine.
That is, the protein in this supplement is not exclusively Whey Isolate, but the brand itself mentions this on its official page.
Then, you will find a curious ingredient, presented as a flavor enhancer.
This flavor enhancer is Glycine, a non-essential amino acid.
We won't go into too much detail on this subject for now, as we've already done it in previous reviews, as in the case of Whey Prime 2.0 that you can find here.
Finally, depending on the flavor you choose, you have different ingredients, such as flavorings, sweeteners, etc.
You will find the complete official nutritional table here.
It is in the nutritional table that this supplement starts to get really interesting.
As in the case of Xcore Whey Hydro Isolate SS, the percentage of total protein in this supplement (88%), is exactly equal to the total percentage of ingredients used as a source of protein.
For this to be possible, all ingredients in the mixture would have to be 100% protein / amino acids, which is not the case.
Isolated Whey, however good it is, is not 100% protein.
So, how does the Iso Whey Zero can you reach 88% of protein?
While Xcore in its Whey Hydro Isolate SS has chosen to use Creatine, Biotech USA bet on Glycine discreetly, to increase the protein content of Iso Whey Zero.
By placing Glycine as a flavor enhancer, and outside of the Iso Whey Zero Blend, it makes it possible that this supplement can actually reach 88% of protein.
The problem is that part of this protein is not Whey, it is not Whey Isolate and much less is complete protein.
They are amino acids.
And some of them are not even essential, like Glycine, Glutamine and Arginine.
What does this mean?
You are buying a supplement of Whey Protein Isolate, which is not 100% Whey Protein Isolate.
What is the percentage of Whey Protein Isolate?
Good question, but no answer.
Biotech USA does not reveal the percentage of Whey Isolate, and as if that were not enough, it does not present an aminogram for this product.
The only data that the brand reveals in relation to amino acids are those of BCAA's, which theoretically are 19.6%.
The values shown are those practiced by the Prozis store at the date of the analysis, and for this reason, they are always subject to change.
Each shake has 22g of ?protein?, and the value varies between 0.79? per dose in the 500g and 0.64 g version? in larger format.
What does this mean? Is it a good or a bad price?
That's an average price for a quality protein isolate.
The problem is that we don't really know what we are buying.
90% Whey Isolate with 10% Amino Acids?
50% Whey Isolate with 50% Amino Acids?
If it is the first hypothesis it is good, if it is the second, no.
Where to buy?
You find this supplement available here and you can still use the code GVIRTUAL to get a discount.
Biotech USA has a curious supplement here.
What exactly are we buying? We do not know.
However, at first glance, it appears to be a quality supplement and easy to recommend.
In fact, we did it ourselves here.
The addition of amino acids to protein supplements is common, and although it is not desirable, it is not always a big problem.
An example of this is the Isogreat from Scitec Nutrition.
Scitec added L-Glutamine and L-Arginine to the Isogreat formula, however, presents the aminogram of your product, we know what we are buying, and we can confirm that it is a good supplement.
In the case of Iso Whey Zero, there is no aminogram, just the information that there are some added amino acids and a questionable flavor enhancer.
Is it a bad supplement? Do not.
It is most likely a quality protein that is quite acceptable, but as it presents itself as a high quality Isolated Whey, it is not up to the level of competition from Isogreat or Iso: Pro, although the price is quite similar.
