You’re not the only one if reading up on the different types of protein powders leave you confused. Casein is a slower digesting form of protein. There are many reasons bodybuilders use casein protein supplement in their diet. Casein helps in greater muscle retention.
Whenever you're going on a lower calorie diet, one of the first issues that will become a growing concern is lean muscle mass loss. Since you will not be supplying enough calories to fully support all the energy needs required throughout the day, you're forcing your body to turn to stored body tissues for energy.
In the best case scenario this will come from your body fat tissue, and in the worst case scenario the body will tap into your muscle for energy. Typically, on the average weight loss diet it's a mix of both. Since casein protein is a form of protein that is higher in calcium content that also proves to be a benefit in terms of total fat loss.
Another very important benefit of casein protein powder is that it helps promote colon health. In a study performed out of Australia, researchers investigated the health benefits of various proteins and found that dairy proteins promote colon health better than meat and soy. This proves to be yet another reason why you should strongly consider adding casein protein to your daily intake.
Finally, the last benefit you'll receive by introducing casein protein into your diet is that of it being one of the best high quality sources of protein available. While meeting your minimum protein requirements is always top priority, if you're taking in high quality sources of protein to meet these requirements less will be excreted by the body and you'll need less overall to maintain lean muscle mass.
If you were taking in lower quality sources of protein and just meeting your recommended minimum requirements, this will negatively impact you because if not all of that protein is absorbed, you then will not actually be meeting those minimum requirements.
