Health Benefits of Casein protein

This supplement has been used in connection with the following health conditions:

2 Stars Athletic Performance Refer to label instructions	Casein protein is more slowly digested than other animal proteins, resulting in a slower, prolonged rise in blood levels of amino acids, so some speculate that it may better support protein synthesis by the body compared with proteins like whey protein that are more rapidly digested. Casein protein is more slowly digested than other animal proteins, resulting in a slower yet more prolonged rise in blood levels of amino acids.3 This has led to speculation that casein may support protein synthesis by the body for a longer period of time compared with proteins, such as whey protein, that are more rapidly digested. However, in two double blind trials, measurements of muscle protein synthesis after leg exercises were similar whether casein or whey protein (either 20 grams or 0.3 grams per 2.2 lbs body weight taken one hour after exercise) was consumed. Other double blind studies have shown that adding protein supplements to a weight-training program improves gains in muscle mass and strength, but only one trial has compared using casein alone to other proteins for improving body composition and muscle strength. In this controlled trial, overweight men were given a low-calorie diet along with a weight training exercise plan for three months. Men who followed this plan and also took 1.5 grams per day of predigested casein protein per 2.2 lbs body weight gained more strength and lean body mass, and lost more body fat than did men using a similar amount of whey protein along with the same diet and exercise plan.
Obesity	Casein protein in milk may aid weight loss due to its effect on appetite, calorie burning, and body composition. Casein, the main protein in milk, may aid weight loss due to its effect on appetite, calorie burning, and body composition.4, 5 In a controlled trial, overweight women dieted for four months using a low-calorie diet that included three daily shakes made from either casein or soy protein.6 Both groups lost similar amounts of weight, with similar improvements in body composition, suggesting there was no difference in the weight-loss benefits of soy or casein protein. In another controlled trial, overweight men were given a low-calorie diet along with a weight training exercise plan for three months. Men who followed this plan and also took 1.5 grams per day of predigested casein protein per 2.2 lbs body weight lost a similar amount of weight as did men using a similar amount of whey protein along with the same diet and exercise plan. However, the men using casein protein gained more lean body mass and lost more body fat than the men using whey protein.7

How to Use It

Some benefits of casein protein have been demonstrated with as little as 20 grams per day. For improving body composition with weight training, 1.5 grams of casein protein per 2.2 pounds body weight per day has been effective.

Where to Find It

Milk protein is 70 to 80% casein, so milk, yogurt, cheese and other dairy products are high in casein. Nondairy foods sometimes contain added casein as a whitening or thickening agent. Casein is also used in some protein supplements.

Possible Deficiencies

People who do not include dairy foods in their diets do not consume casein. However, the amino acids in casein protein are available from other sources, and a deficiency of these amino acids is unlikely in a typical Western diet.
