Whey protein is basically protein powder that comes from milk obtained from cows. Milk includes 2 proteins: whey protein (around 20%) and Casein (around 80%). The main difference between these two proteins stands in the fact that whey protein steps out as more soluble. Most bodybuilders out there consider whey protein as the most important type of protein that has to be included in their nutrition plan. Now the question we need to ask ourselves is whether or not whey protein is actually useful for bodybuilders and athletes in general.
Whey protein appears as complete protein that comes with all the important amino acids you need. We can say that all the elements that this protein brings to the table will be very good for all athletes. Our body actually needs high quantities of branched chain amino acids (BCAA) after and during working out. Whey protein is the richest source of these amino acids. If we are faced with low BCAA levels in our body we tend to be more fatigued. This usually happens after a good workout so we do have to replenish BCAA levels. Now you understand why a lot of professional bodybuilders will consume whey protein shakes.
Even more good news comes from the fact that whey protein is easy to digest and soluble. This means that it will quickly enter your body and the important amino acids will appear and be taken to the body tissues that need them. You should know that whey protein is included in a lot of formulas and protein supplements because of this reason. Also, you should be aware of the fact that there are no documented whey protein side effects and only benefits. On the other hand it is always recommended that you respect the protein intake recommendations that the professionals have highlighted in the past. Bodybuilding supplements that contain such a protein will even be good for vegetarians because we are dealing with powder form and only the substances that are isolated.
