In this informative video, PictureFit breaks down the differences between whey concentrate and whey isolate protein supplements. Whey concentrate is made by "concentrating" the milk proteins in whey, resulting in a protein yield of around 80% with the remaining 20% consisting of milk sugars, fats, and flavoring ingredients. On the other hand, whey isolate goes through processes like ion exchange filtration and ultrafiltration to isolate the milk proteins even further. This leads to a higher protein yield of 90% or greater by weight, and it also removes most, if not all, of the remaining lactose. Both whey concentrate and whey isolate have similar amino acid profiles, high levels of absorption and digestibility, and contain immunoglobulins and lactoferrins that are good for general health. While whey concentrate may potentially have a slight advantage in fat loss, total protein intake from either whey concentrate or whey isolate, as well as from whole foods, is what matters most. Overall, whey concentrate provides virtually the same fitness benefits as whey isolate at a lower cost, making it a practical choice for most individuals. However, whey isolate may be preferable for those with lactose intolerance or for athletes who need to meticulously track their protein intake.
