Optimum Nutrition Casein is a low carb protein. It can be of benefit to weight trainers or strength athletes. Optimum Nutrition Casein is digested slowly by the body to provide a constant source of this important nutrient.

Low Carb Slow Digesting, Anti Catabolic Miceller Protein.

Sometimes slower is better - especially when it comes to the rate of protein digestion. While rapid protein absorption is desirable immediately before or after exercise, delayed release is probably more beneficial throughout the remainder of the day. Casein proteins are pH sensitive and gel in the acidic environment of the stomach. As a result, it can take more than twice as long for caseins to be broken-down into their amino acid subcomponents than whey and other proteins. Casein is the most abundant protein present in milk. It is considered a high quality protein because it is easily assimilated and it supplies sufficient quantities of amino acids that cannot be synthesized by the body.

Another benefit is increased satiety (feeling of fullness or satisfaction). Casein exerts a slight pressure on the stomach walls. In effect, this pressure signals to the brain to stop eating because the stomach is full. Casein is the most slowly digested and absorbed type of protein. This helps create a timed-release effect, providing a steady stream of amino acids to your muscles over a long period of time. The net result is a greatly enhanced anti-catabolic environment which is much more friendly to growth and recovery.

Bodybuilders and athletes looking to build lean muscle, prevent muscle breakdown, and reduce recovery times, and individuals interested in improving the quality of their sleep can greatly benefit from casein.


Use ON 100% Casein Protein first thing in the morning, immediately before bed, in place of small meals, and/or any other time when delayed protein absorption is desired. To encourage a positive nitrogen balance, consume approximately 1 gram of protein per pound of body weight per day from a combination of high protein foods and supplements. For even better results, consume your daily protein allotment over several small meals spread evenly throughout the day.
