how to choose whey protein

Whey Protein 80%, 90% or 100% Concentration-Which One To Choose?

Whey: Where does it come from?

Whey or whey protein is obtained by filtering cow's milk. Once filtered, the milk leaves 2 parts: whey and casein.

There are various factors that play on the quality of manufacture of whey:

  • The filtration process
  • Process temperature
  • The quality of the original milk

Whey is therefore a natural food obtained by mechanical processes.  It is a dairy product rich in protein (at least 80%) and essential nutrients:

  • carbohydrates
  • lipids
  • vitamins
  • minerals

Whey has become a very common product among all the athletes.

It's even a huge business for the food supplement industry.. 

And as you begin in the bodybuilding sport or you are a professional, it is vital to know how to make the right choices. And before looking for the best protein powders, I will show you right away how to detect the scam about the whey ...

"Whey 100%": a pure scam

If you browse the net looking for whey, you will inevitably come across products that claim to be wholesale, wide "WHEY 100%".

This marketing technique aims to make you believe that this product is superior to whey 80% (concentrate).

But the truth is that 100% whey just does not exist , here's why:

You've seen just before the whey is obtained from a milk filtration. And the result of this filtration is a product that contains proteins (about 80%) but also carbohydrates, fats, vitamins and minerals ... all these extra elements take up space.

So when you take a dose of the final product you cannot have 100% protein because whey does not contain only protein.

The name "Whey 100%" is therefore simply false . End of the discussion.

The REAL difference between whey concentrate, isolate and hydrolyzed.

Once you have closed your eyes to this 100% whey is a scam, you still have to determine the type of whey protein that suits you best:

  • Whey concentrate
  • Whey Isolate
  • Whey Hydrolyzed
  1. The concentrated whey contains about 80g of protein per 100g.
  2. The isolate contains about 90g of protein per 100g.
  3. The hydrolyzate contains about 95 g of protein per 100 g.

Note: this is the percentage of protein in the whey BEFORE formulation. This is not the percentage contained in the box you buy (final product).

You will see that for 100 g of product the difference in protein content will be lower. Not to mention the fact that one never consumes 100g of whey . This should be done on 30g doses.

The whey isolate and hydrolyzed are whey which have undergone additional treatment to:

  • Reduce carbohydrates (and therefore lactose)

  • Reduce the amount of fat

If you are lactose intolerant, isolate and hydrolyzate could be a good choice. 

Finally, if you have a tight budget , you should know that the isolate and hydrolyzate are more expensive products, because of the additional treatment they are subject.

But the most important, in my opinion, is not the percentage of protein.

The important thing is the composition of the final product : what exactly is in each scoop? What exactly is in the box?.

It is by reading the label of the product in the back ,it will be possible to known whether this product is good or harmful.

Choose between concentrated whey, isolate and hydrolysed whey

My opinion is that concentrated whey is the most interesting product , here's why:

If you remove the fat from the milk (as for the isolate and the hydrolyzed) you lose many essential nutrients :

  • The lactoferrins

  • Immunoglobulins

  • And other precursors of glutathione ( human antioxidant)

So if you do not have a problem with lactose, concentrated whey (80%) is definitely the best choice.

There is also another factor: Taste.

The concentrated whey fats give it a taste far superior to other products. If some products look better than others it is very often because of their fats content.

The most important is to choose a healthy product , ie a product that contains no harmful additive such as:

  • aspartame

  • sucralose

  • Acesulfame-K

  • Sugar

  • Fructose

  • Artificial flavors

  • "Natural aromas"

The vast majority of products contain these additives.


  • Optimum Nutrition Gold Standard
  • Dymatize iso 100
  • BSN Syntha
