Whey Protein: Isolate, Concentrate or Hydrolysed?

Friday, June 14th, 2013

I often get asked about the key differences between using whey isolate or whey concentrate, or is there something even better? So I thought a short article on the subject may be useful to you guys out there.  So here it is:-


Whey Concentrate

Whey concentrate is one of the most basic forms of protein, and tends to be a cheaper method of supplementing protein into your diet.  It can be used both pre and post workout, as well as to supplement protein intake throughout the day.  Due to the lower cost of whey concentrate it tends to work out cheaper per serving.  However some people tend to have more of a difficult time digesting the stuff and can end up feeling bloated and gassy.

Whey concentrate tends to be anywhere between 34-80% protein (even if the label says 100% whey protein), so make sure you have a good read of that nutritional information on the back of the packet and make sure that percentage figure is talking about the contents not just the source of the protein used.

Whey Isolate

Whey isolate tends to be purer, as such also a little more expensive.  As the molecules tend to be a little bit smaller these products tend to mix a little better.  With very low levels of fat and lactose they also tend to be good for those who are watching fat intake, also for those who are lactose sensitive.  They also tend to be absorbed very quickly making them perfect for pre and post workout.  Whey Protein Isolate contains 87% to 95% protein.


Hydrolysed Whey

This is protein that has been  hydrolyzed, producing small chains of amino acids called peptides. Several studies have shown that protein hydrolysates containing mostly dipeptides and tripeptides.  These are absorbed very rapidly than free amino acids.  These whey hydrolystate’s tend to be the most expensive but due to the fast absorption rates  and the growing evidence that they have a greater anabolic effect, they really are the best of the best.
