Protein, a complex molecule comprised of amino acids, is one of the essential macronutrients, along with carbohydrates and fats, that make up a person’s diet. Protein provides the building blocks for muscles, tissues, organs, and other cells in the human body. The body cannot store amino acids, so people must consume them through their diets.

Protein powder is a nutritional supplement derived from animals, plants, milk, or eggs that people use to add protein to their diets. For example, people can add protein powder to baked goods or drinks, such as milk and smoothies.

Supplementing diets with protein has various health benefits, including:

Weight loss

Protein powder may support weight management.

Overall, research suggests that high protein diets promote fullness and regulate appetite, leading to decreases in body weight, weight circumference, and other health metrics, such as triglycerides and blood pressure.

A more recent review of studies found people with overweight or obesity who supplemented their diet with protein powder experienced an improvement in cardiovascular disease risk factors and body composition.

Muscle recovery

A 2018 review found that protein supplementation after a resistance or endurance workout improves physical performance and enhances recovery.

A similar review found that taking whey protein after exercise restores contractile muscle function and enhances muscle strength. In addition, a recent 2020 study found that supplements containing leucine, an essential amino acid critical for muscle growth, reduce muscle fatigue in wheelchair basketball players.

Muscle mass maintenance and growth

Increased protein intake in conjunction with resistance training, is widely understood to be essential for building and maintaining muscle mass. Research notes that consuming more protein during resistance training may help the body maximize the muscle-building benefit of protein.

However, the study also states that there is only a marginally greater effect on muscle building if a person consumes more than 20 grams (g) of protein for their workout.

Nutritional supplementation

Athletes, older adults, and people who require higher protein levels than they can easily obtain from food alone may benefit from supplementing with protein powders. Similarly, those who follow vegan or vegetarian diets may find that protein powders help them reach their daily recommended protein intake.

Some people may prefer to consume gluten-free protein powder.

People with celiac disease or non-celiac gluten intolerance may need to avoid products that contain gluten, including supplements. People who have these conditions may want to avoid protein powders that contain wheat or gluten-containing grains, as these can trigger symptoms such as:

People who follow a gluten-free diet, including consuming gluten-free protein powder, should ensure they consume a balanced diet that includes all the essential nutrients. Depending on which foods a person omits when following a gluten-free diet, they may develop deficiencies in the following nutrients:

Some gluten-free protein powders may also contain these essential nutrients.

There is a wide variety of protein powders available on the market today and a range of factors to consider before purchasing:

  • Protein types: Protein powders may derive from animal or plant-based protein. Plant-based products often contain soy, hemp, and pea protein, whereas animal-based products often contain whey, casein, and egg.
  • Ingredients: Some protein powders may contain artificial colors, flavors, and added sugars. Always read the ingredients list carefully before purchasing.
  • Fiber content: Some protein powders contain more fiber than others. Fiber helps people feel fuller for longer, which may support weight management.
  • Isolate vs. concentrate: Whey protein isolates contain more protein than concentrates and have minimal fat and carbs, including lactose. Isolate protein powders may benefit those with lactose intolerance.
  • Dietary requirements: People with nutritional needs should ensure the protein powder they purchase does not contain any ingredients they wish to avoid.
  • Flavor: Protein powders are available in different flavors or unflavored. Unflavored products are more versatile and may suit those who use protein powder for cooking or baking.
  • Cost: The price of protein powders varies across brands. Additionally, some types of protein powder, such as whey isolate, may be more expensive than whey concentrate, for example.
