While just picking the right flavour can be a tricky decision, we’ll cut through the noise so that you can decide whether whey protein isolate or whey protein concentrate is best for you

Walk down the aisle of your local supplement shop and you’ll see rows upon rows of different protein powders and a variety of flavours. Among the key decisions you’ll encounter is the choice between whey isolate and whey protein concentrate. Your selection between these options will hinge on your personal preferences and specific dietary requirements. But, as we delve deeper, you’ll discover that not all scoops are crafted alike.

Coach at CaveFit, nutritionist and sport scientist, Fallon Clark MSc describes whey isolate and concentrate as the undisputed “top dogs” of the protein world, both with similar benefits, but different characteristics.

Here, with the help of Clark, we share the protein pros and cons of whey isolate vs whey protein concentrate, and which one you should be stocking your kit bag with.

Whey protein concentrate is one of the most widely used supplements by athletes and gym goers alike. It has 80% protein content and delivers all nine essential amino acids.

Clark explains, ‘Whey concentrate is milk extracted and acknowledged as the most cost efficient protein on the market. After the milk extraction process, whey concentrate still retains a high quality protein content. However, commercially available whey protein powders can range from 30% to 80% protein content, depending on the product grade.’

While whey protein concentrate is filtered, it does contain higher amounts of lactose and is absorbed more slowly into the body. According to research published in Scholars’ Research Journal, whey protein concentrates contain a low level of fat and cholesterol but, in general, have higher levels of bioactive compounds, and carbohydrates in the form of lactose.
