Recently, I have read an article on the internet, comparing a well-known whey protein to another.
From this comparison, I came up with the idea to let the public know if it is viable and if its result is reliable and why. But most importantly, I will reach these conclusions through an educational process. Through this I will teach you how to properly compare two products and what to look out for.
How do we compare two products?
In my workshops as an educator on nutritional supplements, I always stress that we must first learn how to properly read a label of a dietary supplement and then move on buying it. A product that “works” or “sits” well with someone does not mean that it will happen to us.
So let’s look at the two nutritional panels in the comparison above:
The comparison is there (it isn’t inappropriate) but it has 2 main vulnerabilities:
- Both formulations are whey protein mixtures. The first one is appropriate for the typical trainee who is looking for an economical 70-80% protein supplement. It has a combination of isolated and concentrated whey proteins. The second one, however, belongs to a more expensive category, as it is based on whey protein isolate and hydrolysate.
- A well-known protein is deliberately selected to emphasize the superiority of the latter, but if we want to be perfectly correct, the comparison must be made with another supplement of the same company which has the following label:
Let’s go see them in depth …
If we compare now the second label with the third one I added, we will see that: the second (green packaging) has 86% protein content, but the third one has better sources. It contains 83% protein exclusively from isolated and hydrolysed protein. The second option has also whey protein concentrate in the protein blend. Of course it has beneficial properties, but it is cheaper than the other two. What does this teach you? not only the number of protein per 100g alone does play a role, but also the sources from which it comes.
We’re dealing on paper* with two quite good proteins. Any high-protein supplement will help us meet our increased daily needs. These are formulated at 1.6-2g / kg body weight in trainees who target for muscle hypertrophy.
This article is not hostile to any party. I have just want to inform the consumer in general. *If we take for granted that what we see on the labels also exists in the tubs, we are talking about 2 + 1 (=three) quite good protein supplements. I would compare them more in practice in terms of their amino acid content (in the green packaging as much as I searched for it online I cannot find the amino-profile), their taste and solubility, rather than their macronutrient content. +/- 2-3% protein content will not make a difference. Everything is judged in the end based on the above and their price. Supplement reviews and comparisons will follow in the near future. Stay tuned…
