Milk Protein Isolate

Protein is essential for the health and development of the body. It may be used by athletes and bodybuilders to assist in the formation of lean muscle mass and recovery, following rigorous training sessions. Although protein can be found in foods such as eggs, dairy, legumes and certain meats, the American College of Sports Medicine suggests that milk protein isolates are often supplemented in the diets of those who follow vegan diets or are lactose intolerant.

Identification

Protein isolate is the purest form of protein, according to the American Dietetic Association. It contains very little fat, carbohydrates or lactose and can be used as a daily supplement for those who do not consume the recommended amount of protein in their diet. Although milk protein isolate is a derivative of milk, the Mayo Clinic website finds that it does not contain milk and may be beneficial for those who are lactose intolerant.

Milk protein isolate is one of three forms of casein protein derived naturally from milk. It is a combination of 80 percent casein and 20 percent whey protein. It is extracted from cow's milk via a filtration process that separates the protein from the milk. The American Dietetic Association suggests that milk protein isolate has very high amino acid composition that makes it ideal for use in protein bars and meal replacement powders.

Function

Bodybuilders use milk protein isolate as a meal replacement or dietary supplement when preparing for a competition, according to the American College of Sports Medicine. Unlike other forms of protein, milk protein isolate is a slow release protein that can take up to 7 hours to be released into the blood stream. The Mayo Clinic suggests that this helps ward off hunger, and aids in the maintenance of lean muscle.

Benefits

Milk protein isolate is easily digestible. The American Dietetic Association finds that this form of protein is recommended for those that suffer from a weak digestive system or have trouble processing certain foods. It can also be used as a dietary supplement in place of protein-rich foods such as eggs or dairy products. The Mayo Clinic suggests that milk protein isolate is a low-calorie, low-sugar meal option if you are looking to lose weight, increase your metabolism or manage your blood sugar level.

Risks

The filtration process used to create milk protein isolate removes many of the nutrients that aid in strengthening your immune system, according to the American Dietetic Association. Milk protein isolate is not recognized by the Food and Drug Administration as a food or drug, and is not regulated by the agency. The Mayo Clinic suggests that the over-consumption of protein supplements by those looking to lose or maintain their weight can actually have the opposite effect. The American College of Sports Medicine recommends that you not consume more than the serving size indicated on the product label.
