Many of us have been confused about the different kind of proteins. We often encounter terms such as concentrate or isolate. But what really is the big difference? Let us dig deeper to the issues and grasp the gist to which supplement is the true winner. It is time for our protein face off folks! No hypes. No glass. No pretenses, just plain facts. So which is better, whey protein concentrate or isolate?
The major difference between Whey Protein Concentrates (WPC) and isolates (WPI) lies in the processing or filtration to get rid of the majority of fat, carbohydrates and lactose that is present in great amounts during this protein supplement raw state. To get a more concentrated protein, whey products have to go either microfiltration or ion-exchange procedure, the end result of which is a protein that is either concentrate or isolate.
Concentrating on the Facts
WPC are created through microfiltration process wherein the protein sources are allowed to pass through very small filters. Since water, minerals and other particles that are contained in the protein source are able to pass through, what remained are the large protein concentrates which are incapable to bypass the filters. With that being said, WPC yields protein about 70-85% and 5% lactose. If you are asking for the advantage, WPC can provide you with the amount of protein you need to achieve that hardcore-built physique you desire in a much lesser price compare to WPI. In addition, concentrates have a higher immune boosting properties and antioxidant levels compared to isolates because they are less processed. However, for people who are lactose intolerant, WPC are not recommended because of the presence of lactose which might cause stomach upset, gas problems and some digestive issues upon ingestion.
Isolating the Truth
WPI has to go through another filtration process called ion-exchange or cross-flow microfiltration. In this process, protein isolates almost becomes exclusive from carbohydrates, fats, and lactose. WPI is protein in its purest form. It contains about 90-94% of protein, a much higher ratio compared to WPC and also a higher biological value necessary to keep up with your aggressive rim. In addition, people with lactose intolerance have no problem taking isolates since it contains virtually no lactose. You can rest be assured that with WPI you won't have to deal with annoying bloating problems. However, the major drawback with WPI is its much costlier price tag compared to WPC. Truth be told, the more filtration process a product has to undergo, the greater the protein and the biological value, the higher the expenditure. Another point for argument is the loss of important immune-boosting properties such as lactoferrin and alpha globulins which have been degraded during the microfiltration process.
The Verdict
Considering the current financial dilemma we are experiencing today, it is easier to resort to much cheaper protein supplements that will supply our protein requirements and at the same time light on the wallet. For some, concentrates are good enough when trying to include extra servings of protein in their diets. However, for most fitness experts, isolates would always be the better option since it has a greater quality and amount of protein compared to WPC.
