There are plenty of protein powders out there today. No one can deny that protein powder is convenient for us to take while we're on the road or on the run (literally and figuratively). In our busy world, we settle for fast food to give us a quick fix. While this doesn't really help us with our health needs over the long run, it does give us sustenance for the short run-but that's not necessarily good. Fast food is inundated with fat, carbohydrates, sugars, etc. If you're busy (and who isn't these days) then start taking protein powder with you. The question, then, is which one you should take.
Whey protein concentrate-While whey concentrate is good in regards to the amount of protein you get, it isn't the healthiest. It doesn't separate from the fat of the milk, and sometimes there is filler in it to bulk up the product. You might as well eat a bacon cheeseburger.
Powder Protein
Casein-Casein is pure, but it's slow to absorb in your body. If you're going to the gym shortly after work or you need a really quick energy boost, casein won't do you any good. It is good for post-workouts, through.
Egg White Protein-People often associate eggs with having lots of protein, but if you're talking about powder form, it's not true. There are low amounts of it and you need to take more in order to get what you would with the best protein powder in...
Whey Protein Isolate-This protein is void of the fat, carbs, sugar, and cholesterol. It's good for you because it's fast to absorb, tastes great and can come in flavors of chocolate or vanilla, naturally sweetened, and extremely high in protein allowing you to be fuller longer.
