Protein Isolate vs. Protein Concentrate


When it comes to protein, most people know that there are a number of different sources of complete proteins ranging from soy products, to meats, poultry and etcetera. However, when supplementing with protein, you must consider that there is a distinct difference between types of protein that you should be conscious of; protein isolates versus concentrates.

First off, the more commonly used form of protein powder consumed by your average person is whey protein concentrate. This is an ideal form for those looking to add a little more protein to their diet for a number of reasons. This is primarily because whey protein concentrates take longer to digest than their counterparts, which means that you are supplying your muscles with a protein source that will remain in your system for an extended period of time. This form of protein is great to take after a workout, but is also even better to take before you go to bed when your body goes for an extended period of time without fast, a.k.a. a fast. This ensures that muscle tissue is preserved during times of possible catabolism during sleep.

On the other hand, whey protein isolate is more ideal when taken after a workout as it is pre-digested and therefore a faster acting protein than a concentrate. After a strenuous workout, your muscle needs a pure form of protein that will be delivered to the muscles at a fast a rate as possible. Consequently, whey protein isolate is not the most practical form of protein to take before bedtime as it digests very quickly and will not necessarily ensure that the muscles are supplied with a long lasting protein source. However, in order to mimic the longer acting properties of a concentrate, you may also add peanut butter to your protein isolate powder to slow down the rate of digestion. So the next time you go to buy protein powder, consider what form is most practical for you, or perhaps designate certain times to take each as many people do.
