What is the difference between whey protein concentrate and whey protein isolate? That is a question we are asked on a daily basis! We are proud to have over 20 different proteins on offer here at TPW. Yet we know this can make selecting the best one for you a little confusing. So here’s a helpful guide and all you need to know about whey protein concentrate and whey protein isolate.

What Is Whey Protein Concentrate?

Whey is simply the liquid bi-product you get when making cheese. Once you remove water and casein content from this bi-product, you are left with whey protein concentrate.

Whey protein concentrate is possibly the world’s most popular sports supplement today. Whey protein concentrate is widely considered to be the most efficient and economical form of protein for the human body to digest and use. Whey protein concentrate is micro-filtered and not heat treated to produce ultra pure protein. This process ensures that the protein stays intact and as pure as it can be. It also means the powder to mix easily and achieve a smooth 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.

What Is Whey Protein Isolate?

While whey protein concentrate has a protein content of around 80%, the protein content of whey protein isolate is more like 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 is believed to have less fat, cholesterol, lactose, carbohydrates and calories than most other proteins on the market. It is therefore a common choice for those looking to maintain low levels of body fat but who still require the protein to help their muscles repair and recover. Although whey protein concentrate is already considered low in lactose, whey protein isolate is considered even lower because of the additional manufacturing processes. Whey protein isolate is therefore often recommended for athletes who suffer from lactose intolerance.

Whey Concentrate Vs Whey Isolate

People have long debated which one is better, whey protein concentrate or whey protein isolate. The truth is there is no outright winner and it largely depends on your personal nutritional goals. There are differences between whey protein isolate and whey protein concentrate. Whey protein isolate has a higher protein content and is lower in carbohydrates, lactose and fat. But it is typically more expensive due to the additional manufacturing process it undergoes. Here at TPW, we think it’s worth asking yourself whether the additional benefits are worth the price tag. And as explained above, often they are if you’re goal is to keep your body fat low or if you’re lactose intolerant.
