However, with such a variety of options available, some people may not know which protein powder is most suitable for them.

Although the Recommended Dietary Allowance for protein in the general population is about 0.35 grams (g) of protein per pound (lb) of body weight, those who are active may benefit from a higher protein intake.

The American College of Sports Medicine recommends roughly 0.5–0.9 g of protein per lb of body weight for those who are physically active.

People should aim to get sufficient protein from their diet, but this can sometimes be difficult due to dietary restrictions or costs. Therefore, protein powder supplementation may be a suitable alternative to help people reach their nutritional goals.

The most suitable protein powder for each individual will vary, as people will need to consider their health goals and any dietary restrictions they have.

The makers of protein powders isolate the protein in foods to make a nutritional powder. Some of the most popular variants include milk proteins and plant proteins, which are ideal for vegans. Some manufacturers may also use egg protein.

People who choose milk proteins can choose from two primary milk derivatives: whey and casein.

Whey protein is a fast digesting protein that the body can quickly absorb. This means that it is a suitable protein source for a pre- or post-workout snack. Casein takes longer to digest, so people may prefer to use casein before fasting or going to sleep.

Whey protein is also typically available in three formats:

  • whey protein concentrate (WPC)
  • whey protein isolate (WPI)
  • whey protein hydrolysate (WPH)

Each type undergoes a different manufacturing process to determine its protein concentration and attributes:

  • WPC: This form is the least processed and also usually the cheapest. It contains roughly 29–89% of protein and other nutrients, such as fats and carbohydrates.
  • WPI: This form has a slightly higher protein content, at about 90%, and it contains far fewer carbohydrates and fats. It requires additional processing and tends to be more expensive.
  • WPH: This type is the most processed form and is “predigested,” meaning that it has undergone partial hydrolysis. This means that it is easier for the body to digest and use.

Plant proteins such as hemp protein and pea protein are options for vegans, people with lactose intolerance, and those whose bodies do not digest milk protein well.

However, plant protein powders may not be complete by themselves, meaning that they may not contain all nine essential amino acids. A 2019 review notes that manufacturers can make plant protein higher in quality by either blending or supplementing them with other protein sources to create a complete protein profile.

The Food and Drug Administration (FDA) does not regulate dietary supplements such as protein powders as strictly as pharmaceuticals. Therefore, it is the responsibility of the manufacturers to evaluate product safety and label them accordingly.

An analysis by the Clean Label Project suggests that some protein powders may contain high concentrations of harmful metals. Therefore, it may be advisable for people to investigate what the manufacturers do to reduce contamination and whether or not the product has undergone third party testing.

Protein is an essential macronutrient that helps build muscle, repair tissue, and make enzymes and hormones.

One 2017 review indicates that protein powder supplementation is a safe and convenient method of ingesting high quality dietary protein.

Following a high protein diet can help a person build muscle mass, reduce appetite, lose weight, and aid muscle recovery after exercise.

People should always follow the instructions on the packaging. Typically, this will involve taking a scoop of protein powder and mixing it with a liquid to make a protein-rich beverage.

Popular mixer options include water, milk, milk alternatives, and yogurt. Some people may also consider blending fruit into the beverage to create a more nutrient dense snack.

Protein is a vital macronutrient to include in the diet. Using protein powder may be a helpful way for people to add more protein to their diet.

There are many protein powders available to suit people’s dietary restrictions and requirements. People may also wish to consider their health and fitness goals when choosing a protein powder.
