During sleep the BCAA are catabolized into energy sources. You can supplement the BCAA at bedtime to provide an outside source of protein, rather than your own tissues. Supplementing the BCAA at bedtime is a method to possibly support the body’s ability to minimize protein breakdown. An added benefit, the body needs to burn fat to provide energy to convert the BCAA into the chemical energy ATP. Thus supplementing the BCAA at bedtime can help burn fat as well as spare protein tissue.
It is advised at bedtime, if you supplement the BCAA, eat a little cottage cheese with a small amount of fruit. The fruit will help provide energy for the catabolism of the supplemental BCAA. The cottage cheese will work in synergy with the BCAA, making the two more effective at minimizing protein breakdown. If you work out lifting weights, taking BCAA at bedtime is a method to spare protein loss, thus helping you preserve the muscle you are gaining from your workouts.
