is it better to take in whey protein mixed with water after workouts or whey protein mixed with milk after workouts, milk has casein protein which digests slowly so would it slow down the whey protein digestion as well if they are mixed together compared to whey being mixed with plain water?

I think your pushing the intelligence limits of Sherdog.

I can't answer your question but I can only state from what I know and read that it is beneficial to take a protien after your workouts. I have read nothing on if milk slows down the absorption rate.

It depends on your goals. If your top priority is to cut weight, I'd skip the milk. If your top priority is performance gains, I'd use the milk because the carbs will help with recovery. Neither option would be my top choice of PWO drinks but my goals may not be similar to yours either. If you want more information on recovery drinks just search the forum... this has been beat to death and we have threads up the ass in regards to workout drinks and recovery.

According to the information below, no. I attempted to find the actual study but I could not locate it... so take it for what you will.

Milk protein is composed of 80% casein and 20% whey. Milk is interesting in that, believe it or not, the whey and casein fractions are absorbed separately. In one study, subjects consumed skimmed milk and were evaluated over the course of eight hours. With milk-protein ingestion, there's a rapid rise in blood amino acids within one hour (probably as a result of the whey fraction), a plateau from one to three hours (a combination of simultaneous whey and casein absorption), and then there's a progressive decline over the course of the next eight hours. However, blood amino acids are still elevated at the eight hour point as a result of the casein fraction. (5).

Yeah, I seem to remember that whey and casein are independent of each other, even when taken at the same time. So, really, it's about calories, taste and lactose tolerance. I drink my PWO shake with just water since it doesn't really taste that different to me, is more convenient (I use the same bottle as my Peri-WO drink), and doesn't give me explosive diarrhea (16 oz of milk will do that to me).
