    First, Whey protein (any variety) is a fast digesting protein where Casein is a slow digesting protein. Whey is what you want immediately after a workout. Casein is what you want before you go to bed.

    Now, Whey Isolate is more highly filtered than plain Whey or Whey concentrate. This is especially important if you are lactose intolerant. If so, Isolate is the way to go. If not, it doesn't matter all that much, especially for a beginner.

    Isolate has more protein (and less fat and crabs) per volume (scoop) than plain Whey. Sometimes Whey is also "micronized" (more finely powdered) to make it digest even faster and mix more easily with liquids.

    That is another difference between Whey and Casein, btw; the latter does NOT mix well at all without a blender. Even stirring with a spoon it will likely be quite lumpy.

    I don't understand what you're asking with the "percentage" question.

    I keep getting conflicting information about how much protein can be digested per meal. I'm not a nutritionist but it would seem to me that it depends on the protein source. In other words, obviously some forms of protein are very easily absorbed into the bloodstream (micronized protein or, perhaps even better, powdered BCAAs). But other protein sources, such as from fish take longer and red meat and Casein take much longer.

    So, I think the question as asked is a bit misleading. The question should be more like, "How much of a given protein source can be digested at once or over a given period of time."

    Again, my take on it is that it is a good idea to have protein in the body immediately after a workout. A scoop or two of Whey should do it. Then take more protein (through a food source, not protein powder) in an hour to two hours. Then again in another couple hours. Etc. If you're concerned you're not getting enough protein through your diet, then you might want to have a scoop or two of Casein before bedtime.

    Ha, yeah, that does help icon_razz.gif

    OP... Since you're relatively new at working out the best advice to be given is to not OVER think this stuff. It is more important to actually get into the gym and work out than over think the whole thing. Educate yourself over the next 5 years about various workout strategies and you'll see, it isn't like there is only one way to do stuff or only one right answer.

    The most important thing is to eat good, nutritious food. I'm a "believer" that having a Whey (or other) protein drink more or less immediately after a work out is a good idea. But it isn't like it is a make or break thing, especially for someone your age. For me, being in my mid 60s, it is a precaution. I'm trying to keep my body 'anabolic' as much as possible. BUT it is more important to eat good, whole food (meat, vegies and some gluten free starches) several times a day than drink 3 protein shakes a day. Now maybe in 15 years when you are HUGE and weigh 220lbs of lean muscle, then you'll need to eat differently than now. But to even GET there, you'll already have had to learn HOW to eat to be that big and still be under 15% body fat.
