Protein shakes can be an easy way to increase protein intake. This may be useful for people looking to put on muscle, lose weight, or promote injury recovery.

A protein shake is a dietary supplement. Typically, it consists of protein powder mixed with water, milk, or a milk substitute. Depending on the manufacturer, the beverage may contain other ingredients such as flavorings, vitamins, and branched-chain amino acids.

People may wish to consider the benefits and risks of protein shakes before making a purchase:

Pros

  • Muscle gain: A 2018 study found that protein intake may be important for building muscle mass.
  • Weight maintenance: A 2019 analysis suggests a higher protein diet may help prevent weight regain after weight loss.
  • Lean muscle gain: A 2018 review found that protein supplementation significantly increased lean muscle gain in people performing resistance exercise training.
  • Preventing muscle loss: A 2019 study recommends adults consume at least 0.8 grams (g) of protein per kg of body weight daily to achieve optimal health outcomes.

Cons

  • Regulation: The Food and Drug Administration (FDA) does not regulate dietary supplements.
  • Allergies and intolerances: A person with dairy allergies or lactose intolerance may experience digestive issues if they use a milk-based protein powder.
  • Lack of research: Few current studies explore the long-term side effects of high protein intake from protein powder and supplements.

When looking to purchase a protein shake, individuals may wish to consider the following:

  • Protein type: The ingredient label should indicate the protein type the product has. People who are vegetarian, vegan, or lactose intolerant should carefully read the label to ensure they can consume the type of protein.
  • Ingredients: Companies must list the ingredients in protein shakes. It is important to read the label to ensure it does not contain any ingredients a person is allergic to or must avoid for dietary or religious reasons.
  • Nutritional values: Comparing how much protein, sodium, sugar, carbohydrates, and more several products contain can help people make an informed decision as to which brand best fits their needs.

Each manufacturer will have a specific set of instructions on shake dosages and frequencies. When people wish to drink a shake, they need to shake the bottle, and it is ready for consumption.

Although there is debate about when to consume a protein shake for muscle gain, a person should consider drinking it within 1 hour of their workout.

People considering protein shakes to lose weight may consume them instead of a meal or with a small amount of food. However, it is important to ensure the shake contains other nutrients beyond protein to help a person maintain a balanced and healthy diet.

There are several ways a person can ensure they have enough protein in their diet. If they wish to consume alternatives to protein shakes, they may consider:

Below, we answer some of the top frequently asked questions about protein shakes.

Is it safe to use protein shakes as a meal replacement?

A person should speak with a doctor before using protein shakes to replace meals.

A 2018 study found that meal replacement shakes can result in an improvement in body composition in both male and female participants with overweight or obesity.

However, protein shakes may not provide a balanced range of nutrients per serving and may include high levels of sodium. As such, many companies do not recommend their products as meal replacements.

If a person is trying to lose weight by replacing meals, they should ensure they are still getting the recommended amount of essential nutrients each day.

When is the best time to drink a protein shake?

Many protein shakes have instructions to drink them either before or right after a workout, usually within 1 hour.

Do you need to exercise when drinking protein shakes?

Yes. A person will not be able to lose weight or build muscle or fitness by drinking protein shakes alone.

Many protein shake brands state that individuals should drink them as supplements in combination with a balanced diet and regular exercise.

In fact, a 2019 study reports that the formula and timing of protein intake are more important than how much protein a person takes.

Ready-to-drink protein shakes provide an easy and convenient way to increase protein intake.

Depending on a person’s goals, these drinks may help increase muscle mass, lose weight, or gain weight.

Protein powders are available to the general public to buy and make at home with a shaker or blender. Alternatively, a person can purchase ready-to-drink shakes that they can consume when convenient.

A person should speak with a doctor before changing their diet to lose weight or build muscle to ensure they are still getting all of their essential nutrients through their diet.
