hydrolyzed casein vs. hydrolyzed whey for post-workout

i've read that the casein products clump together in your stomach and take much more time to digest than whey. does hydrolyzed casein do anything like this or does it digest just as fast as hydrolyzed whey? which one would be better for post workout?

Logically it appears that the smaller the average molecular weight of a hydrolyzed protein, the more quickly it can be absorbed by the body and utilized for workout recovery. PF's Peptopro would therefor be the best choice for post workout (recovery/use) as it's average MW is a miniscule 360 daltons (the smallest size that the PF offers). The next best bet (giving you the most bang for your buck) would be PF's hydrolyzed 520, a hydrolyzed whey concentrate with an average size of 520 daltons.

I do not know the answer to your question regarding hydrolyzed casein ie does it act like a fast digesting protein or a slow digesting protein ... or perhaps even both! Traditionally casein forms a gel in the gut when it is digested, however I do not know the process of how this happens nor if the hydrolysis process would affect gel formation.

Perhaps the "good Doctor", DJones, or debryunda will chime in now ???

sounds good to me

I think the pitch on hydro casein is that since it is partially hyrolyzed, you get a combination of both, but I will also defer to more knowledgeable minds.

Keep in mind that peptopro is a Hydrolyzed Caseinate. Caseinate and casein both gel in the gut and work the same when hydrolyzed fast digesting with some slower benefits. The exception would be peptopro being a better more complete hydro process.

Hydro casein is considered a very good choice for waking and post workout... I use a 40/60 mix of hydro casein and WPI for post workout. However both hydo whey and casein are excellent for post WO. Your choice which you would prefer, all fast hydro whey or most fast with some slower attributes hydro casein.

I though the benefit of hydrolyzed casein was that it is far less bitter than the hydrolyzed whey. I have 520 and Pepto Pro in separate jars and there is a huge difference in taste.

My opinion has always been that the hydro-casein has a similar rate of absorption, but a much better taste that hydro-whey.

Essentially, it all boils down to molecular weight.

For instance, if you take the pepto pro, which is a casein, it is somewhere between 290-310 which makes it mostly if not completely di and tri-peptides (peptides being bonded amino acids as opposed to isolated)

So, when you have a whey that is 520 (daltons) it will be marginally slower than a casein like pepto pro which is 290-310.

I use the pepto pro as a fast digesting protein, whereas the difference won't be that noticeable with any of the other in terms of assimilation, regardless of what people might say.

Bottom line, any of the hydrolyzed proteins on THIS site are going to work. Just pick one and stick with it.
