Casein- Casein is the opposite of whey. It is an insoluble, slow-digesting, milk derived protein. Casein has been shown to be anti-catabolic in several studies but has no effect on increasing protein synthesis. So what is it good for: Casein gels in the stomach and is slow to digest. In fact it takes casein at least 2.5 hours to digest and up to 4 in some cases. For that reason it is good at any meal other than post workout. Casein is an excellent choice especially right before bed since it gives you a slow stream of aminos over about 3-4 hours and prevents muscle breakdown. You need this slow stream of aminos since your body will be going 8 hours without any protein.
Whey Protein- Whey is a milk derived soluble protein that is quickly digested. Whey has been clinically shown to increase protein synthesis by as much as 68% when consumed post workout. This is because whey gives your body a flood of amino acids very quickly, causing a rise in protein synthesis. Unfortunately these same clinical studies showed that whey did nothing to prevent catabolism (muscle breakdown) So what is it good for: Whey is good when consumed post workout because your muscle's need protein fast and whey gives it to them fast, since it is digested in about 30 minutes. For this same reason, you should not take whey on an empty stomach or by itself at any other time of the day. Another reason whey should only really be used post workout is because at any other time when it is taken by itself your body only uses about 30% of the amino acids. You see, whey gives your body such a quick flood of aminos that the body thinks it has more protein than it actually does and it sends the "excess" to the liver, where it is oxidized and used as energy.
