"Milk protein is roughly 20% whey and 80% casein. Thus far in the scientific literature, comparisons of casein-dominant proteins with whey for sports applications are evenly split. Some studies show casein as superior (in spite of a higher leucine content in the whey treatments) [9,10], while others point to whey as the victor [11,12]. The only certainty is that it can’t be assumed that faster is better when it comes to promoting net anabolism. An acute study on post-ingestion amino acid kinetics by LaCroix suggests that milk protein is best left as-is rather than isolating its protein fractions [13]. Compared to total milk protein, whey’s amino acid delivery was too transient, and underwent rapid deamination during the postprandial period. The authors concluded that milk proteins had the best nutritional quality, which suggested a synergistic effect between its casein and whey"
Thanks for pasting that but it doesn't mean anything to me. Whey protein is the fastest absorbing protein and therefore the best post-workout solution.
