Whey Concentrate V Whey Isolate Protein

Whey protein isolate v concentrate? Seen the terms WPI or WPC? Know what they stand for? Neither did we in the beginning.

Protein powders are NOT all the same. 

The most common type of protein is whey. Whey protein is a fast-digesting animal-based protein and essentially a milk by-product. You also get pea proteins, made from peas of course, and plant-based  proteins, which can include hemp, brown rice, and soy. You can read more on the types of proteins available here.

Isolate v Concentrate?

WPI is Whey Protein Isolate. WPC is Whey Protein Concentrate.  

• Concentrate is processed to around 80% protein by weight. 

• Isolate undergoes different processing to around 90% protein plus by weight 

Both concentrate and isolate are quality proteins with benefits. The steps in the production of isolate however result in fewer carbs and fat per serving. Isolate also has a lower lactose content so can be a better choice for those who are lactose intolerant. It is possible to get the same protein intake from concentrate, you just need to have more, and will get the fats and carbs that come with it. 

You may have heard of hydrolysed protein. This is protein that has been further processed through exposure to heat, acids, or enzymes (essentially pre-digested) and can thus be more rapidly absorbed. It is essentially a broken-down version that’s easier on your digestive system, but it can be harder to find, generally is more expensive and on average is used by elite athletes.

Old Bull Preferred

Isolate, bang for buck means 90% protein, so fewer fats and carbs, and rapid absorption, as well as all the essential amino acids. Old Bull Isolate is 95% protein. Old Bull protein is also intentionally high in leucine to support muscle strength and maintenance. Read our protein guide here for more information on what protein is and why you need it.

Numerous studies show that whey protein can help you gain muscle, increase strength, and promote fat loss.
