There is a lot of talk going around involving whey protein vs isolate vs concentrate and it can be confusing.
If you’re new to protein supplements it’s not enough to just buy a protein shake as you must also know the difference between concentrate and isolate.
Whey Protein Isolate Vs Concentrate: The Differences?
The debate and controversy among fitness and sport people about whey protein isolate vs concentrate has continued for many years.
The short answer is that whey concentrate has a higher level of protein. Whey isolate has lower levels of fat, lactose and carbohydrates.
Whey concentrate is more commonly used and it isn’t unhealthy by any means. However, whey isolate offers greater potency.
To further help with the whey protein vs whey isolate debate, here is some more information.
What is Whey Concentrate?
Whey is the liquid that forms when you make cheese. Take out casein and water and you’ve got whey, and this is how concentrate and isolate are made.
Concentrate is easy to digest, and it is micro filtered to ensure that the protein is pure and smooth.
What is Whey Protein Isolate?
Whey protein isolate has a 90% protein content, while concentrate is around 80%. Whey protein isolate undergoes Cross Flow Micro Filtration to remove the fat, lactose and cholesterol so it is purer.

This is the reason why bodybuilders and gym rats like it. The good thing about whey isolates is the effect is more pronounced.

Another benefit of a supplement is you know what the content is and its whey isolate is genuine.
Whey isolate drinks, shakes and supplements are also more potent. A lot of the protein in foods end up diluted due to the artificial ingredients included. Whether it is for short or long term, whey isolates offer benefits.

There are other popular flavors like peanut butter, cookies and cream and cinnamon. It really doesn’t matter what the flavor is as long as it doesn’t affect the proteins.
It should be pointed out that whey isolate supplements will not taste the same even if they’re the same flavor. The reason is these products are processed in different ways so the taste will vary.
One question that you may be asking is if if unflavored protein shakes are better than flavored ones. The rationale behind this thought is that flavors’ additives minimize the benefits of whey isolate.
