Casein is one of the most important bodybuilding supplements geared towards generating mass. Fitness trainers who use casein protein regularly easily generate bulk and general body health. In most cases, casein proteins are usually compared to whey proteins and given an equal importance as bodybuilding supplements. Proteins are the building blocks on which growth occurs.

The search for protein supplements has intensified in the last one decade. Bodybuilders have awoken to the fact that their muscle growth rate is directly proportional to the provision of adequate levels of proteins to the body alongside endurance training. Training without ingesting the appropriate proteins will not yield any new muscle tissues. But what is casein protein? Casein is a by-product of cheese. It is therefore derived from whole cream milk in the cheese making processes.

After collection, protein is curdled to enhance the nutritional value and depending on how much it is refined you can have a variation of quality. We have high quality casein proteins and low-grade casein proteins. High quality casein has been refined further for fast absorption while in the body and to include more protein calories. Although the refining process increases the protein concentration and the speed of absorption, the absorption rate of casein is still under par, as compared to other proteins.

When the casein is collected prior to the curdling process, it results to a low quality product. For the mere fact that in low-grade casein proteins the proteins had not curdled, it is usually referred to as calcium caseinate or simply caseinate. One characteristic of low quality casein besides being cheap is that it has a slow digestion speed. The slow digestion improves absorption of vital amino acids. This is one of the reasons why low quality casein works well as meal replacements. In various literatures, casein has been referred to as the best meal replacement supplement available in the market today.

Casein protein helps in providing energy that can sustain the body for extended periods between meals. More importantly, they help the body with a high absorption efficiency of amino acids that facilitate muscle growth. Proteins must be ingested in high volumes if optimal muscle growth is to occur. This requires that you eat proteins in all the day’s six meals and in high volumes.

Most people find it hard to include proteins in all the meals and even when they do, the proteins always fall below the required ration of about three grams per pound of body weight. This is where casein protein comes in to provide high levels of proteins for the day’s requirements in a supplement form. The slow digestibility and absorption of casein proteins also aids in ensuring that there is a sustained and reliable supply of proteins for the body throughout.

However, as you shop for casein protein, ensure that you only choose the supplements made by reputable manufactures. The high quality casein proteins must be derived from whole milk and then have no chemicals and preservation acids added to it. Casein should be derived from a natural process. Extracting it using artificial processes like use of acids spoils its quality and safety.
