Right before or after training, rapidly digesting whey protein helps start recovery, a process that can take up to 48 hours. Between meals and before bed, when nutritional support won’t be available for a while, casein protein can help provide longer lasting amino acid support. Casein proteins are pH sensitive and gel in the acidic environment of the stomach. As a result, it can take longer for caseins to be broken-down into their amino acid subcomponents than whey and other proteins. Because of their unique slow-digesting qualities, caseins are described as anti-catabolic or muscle-protecting proteins.

Casein Protein

Casein Protein
This nutrient has been used in connection with the following health goals
  • Reliable and relatively consistent scientific data showing a substantial health benefit.
  • Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
  • For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

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

Obesity
Dose: Refer to label instructions
Casein protein in milk may aid weight loss due to its effect on appetite, calorie burning, and body composition. (more)
Athletic Performance
Dose: 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. (more)
Obesity
Dose: Refer to label instructions Casein, the main protein in milk, may aid weight loss due to its effect on appetite, calorie burning, and body composition.1, 2 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.3 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.4

Athletic Performance
Dose: Refer to label instructions Casein protein is more slowly digested than other animal proteins, resulting in a slower yet more prolonged rise in blood levels of amino acids.1 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.

Casein is the main protein found in milk. Similar to other animal proteins, casein is a complete protein, providing generous amounts of essential amino acids.1 However, it is digested more slowly than most other animal proteins, resulting in a more prolonged release of amino acids into the bloodstream.2
