Concentrate or isolate?  What’s the difference?  Well, in a nutshell, isolate whey has a higher protein content per serving.  But the difference is minimal, with concentrate being around 80% protein and isolate being around 90%.  It’s a small difference, but could make a difference.  Isolate is a more refined version, with much more of the fats and lactose acids removed.  If you’re intolerant of (or just not keen on) lactose, isolate would be your best choice, although it can a little be more expensive.


Whey Protein Concentrate

The clue is in the title!  Whey Protein Concentrate is concentrated whey protein.

Whey protein concentrate is, by far, the most popular of workout supplements.  It is generally considered to be the most effective kind of protein for the body, both to use and digest. Whey protein concentrate is made by a process of micro-filtration, rather than being heat treated.  This means that the protein stays fully intact and is as pure as possible.

Also, it means the powder is easily mixed and forms a smoother texture, giving you the perfect protein shake. Whey protein concentrate is rich in both BCAA’s and Glutamine. This makes it the ideal protein to help build muscle size, definition and aid recovery.

Whey Protein Isolate

Whey protein concentrate has a protein content of around 80%, but the protein content of whey isolate is around or above 90%. This is because whey protein isolate undergoes a process called Cross-Flow Micro-filtration. This separates the protein from fat, cholesterol and lactose meaning a purer protein as the end product.

Whey protein isolate generally has less fat, lactose, cholesterol and carbohydrates (reducing the calories!) than most concentrate proteins.  It is a more common choice for those bodybuilders looking to keep body fat down, but who still require the protein to help their muscles repair and recover.  Although concentrate is already low in lactose, isolate has an even lower amount because of the additional processing.  One reason why isolate is often recommended for those athletes who suffer from lactose intolerance.



Concentrate:  Less expensive, less protein, more lactose, fat, cholesterol.

Isolate:  Purer.  Less fats, acids and cholesterol.  More protein per serving.
