Purity and the process of purifying matters.
Isn't casein hydrolosate even FASTER absorbing than whey? Thoughts on that, guys?
absorption rate doesnt matter at all...
That I know. In fact, I take weightgainer with a mix of a bunch of crap that's slowly absorbing
Other stuff i don't understand: The "mix" of whey and casein to create a "time release formula." You don't get the best of both worlds. Whey will not absorb as fast as whey if you're taking whey+casein at the same time. The casein will slow it down... lol
And yes, whey isolate gets absorbed faster, and hydrolyzed whey isolate, even faster, but I thought "new research" showed that casein hydrolosate was faster than both. Whatever, who cares because:
How did the notion that you need to absorb protein as fast as possible (and therefore choose whey) after a workout get so popular? Where are the sources for this? I've heard it a bunch of times but never saw studies. Another thing, I remember reading that whey doesn't hit peak absorption rates until about 45-min to 60-min after ingesting it... so wouldn't it make more sense to take it at the start of the workout, so you're hitting that peak rate as you finish off? I know that more and more people are taking pre- and post-workout whey now, but sometimes people *only* take post-workout for whatever reason when they could easily take it *only* pre-workout.
Another thing I read (lol i need to bring in some sources cuz I'm just rambling) is that a high amino acid profile in your blood isn't what causes muscle synthesis, but the actual
spike in the level of amino acids itself... as an analogy, it's about the acceleration, not the top speed. So what some people were recommending was alternating whey with casein to get greater (as in amount and in frequency) amino acid spikes throughout the day. Sounds like that would make sense to me, but not sure why it's the spike that's beneficial instead of the amino acids themselves. I guess maybe it's the body foreseeing a need to build muscle or something in anticipation of higher amino acid levels. Makes sense to me!
Gotta find these sources though.
