{Chart} Micellar Casein Whey Isolate 24 hour Estimated duration of amino acid delivery over 24 hours

In a randomized, double-blind, cross-over clinical trial that included 20 recreationally trained healthy male subjects, those taking a WPI and leucine blend immediately post-workout showed significant increases in plasma insulin concentration. Those taking the WPI and leucine blend showed 400% more insulin 30 minutes post-workout compared to a placebo.

In a randomized, double-blind controlled study of sixteen health adults, subjects consumed either whey protein or casein containing equal amounts of leucine. While plasma branched chain amino acid levels were highest at 100 minutes post-supplementation in subjects who consumed whey protein, after 300 minuted BCAA levels were higher in subjects who consumed casein compared to those who took whey protein. When combined with a resistance training program. An 8-week study of athletes performing an intense resistance exercise training regimen demonstrated that those using the proprietary module of whey protein and leucine had greater increases in muscle strength and size than those on a placebo.
