What Are the Benefits of Protein Supplements?

Health food retailers, such as GNC, are constantly promoting protein supplements. Some ads claim protein supplements are good for dieters, while other ads claim protein supplements are good for body builders. With the different claims advertised for protein supplements, it may be hard to tell the exact benefits of protein supplements.

Definition of Protein

• Protein, as it pertains to nutrition, is one of three macronutrients from which calories are derived, according to Bio News Online.

Use

• Protein supplements are primarily used to compensate for loss of protein or insufficient protein in a person's daily diet.

Health Benefit

• Protein supplements can benefit those who are protein deficient. According to the Harvard School of Public Health, protein deficiency leads to stunted growth, loss of muscle mass and weakening of the immune, cardiovascular and respiratory systems.

Weight Control Benefit

• Protein supplements in the form of protein shakes and protein bars are sometimes taken as a part of a low fat, low carbohydrate diet. The high level of protein in these supplements digest slowly, leaving you feeling full longer and causes the body uses more energy to digest the protein, which aids in metabolism and burning fat.

Body Building Benefit

• Body builders and those who weight train take protein supplements to aid in the formation of more muscle and the repair of muscles over-worked during weight training. The Protein Supplement Guide recommends a combination of whey and casein protein supplements to help build more muscle.

Considerations

• According to the Centers for Disease Control and Prevention, the general recommended daily allowance for protein intake is between ten and 35 percent.
