still confused! when to take whey protein isolate??

[bocheltree]

Ok. The issue is i've been reading a few articles and came across one specifically on the time it takes to digest whey and casein. In this article, its clearly pointed out that whey digests at about 8g/hour. the author also states several times that the protein takes an hour to get into the bloodstream. These two statements confuse me. So its 8g of my shake in my bloodstream that first hour? or 8g are absorbed and only go into the bloodstream after an hour has passed?

With this issue i'm uncertain if i should take all my whey pre-workout, which may ensure i don't use it as energy because it will not be in my blood-stream for another hour. By that time i will have finished working out and my muscles are ready to suck up that protein.

On the other hand, if it's 8g/hour, will i be using that absorbed protein as energy as i workout? or will it be readily available to repair muscle tissue as long as i have enough carbs stored for energy?

Note that both proteins enter the bloodstream at about the same time, around the one hour mark. Whey simply spikes blood amino acids faster (before falling back to baseline levels around hour 4)


So it’s not that whey gets into the system faster, it just spikes blood amino acid levels higher at the same time point (about an hour after consumption).


Protein Absorption Rate (g/hour)
Raw Egg Protein * 1.4
Cooked Egg Protein * 2.9
Pea Protein 3.5
Milk Protein 3.5
Soy Protein Isolate 3.9
Casein Isolate 6.1
Whey Isolate 8-10***********
Tenderloin Pork Steak 10.0

You must know that it is most important that blood amino values are continously elevated for hours after training, not just that moment once you finish training. The best way to maintain sufficient increase seems to be a pre-workout and post workout meal with sufficient protein&carbohydrates, it does not matter so much whether this is whey protein isolate, or another high value protein, but it seems that slower absorbed proteins like casein are able to produce elevations of blood amino acids for prolonged times. You are always free to supply the protein in either of your meals by whey protein isolate ofcourse, but the importance of when to take whey protein isolate compared to other protein types seems to be relatively small. Personally, I think I would want to take a shake post-workout, but that's just because I have the feeling I am better satisfied on solid foods which gives a better feeling when training.

You kind of complicate the things...I was just like you, wanting to find out the best way to take the whey, the best protein powder, how many minutes be4 and after wk to take it .. blah blah..
You won't use it as energy , considering that it is not the only food you eat be4 wk...
So be4 or after workout is up to you...
