Food sources that are high in protein include eggs, shellfish, nuts like almonds and peanuts, chicken breast, lean beef, milk, Greek yogurt, and turkey breast.Īnd while protein needs vary from person to person, 'I would not suggest consuming more than one protein shake in a day to allow for other macro and micronutrients into the diet,' recommends Hagensick.

While most people can get all benefits of protein from a balanced diet alone, some people need supplemental protein as well. Protein shakes can also help with weight management as they 'increase satiety − a sense of fullness, without a significant increase in caloric value,' says Fatima Cody Stanford, MD, director of diversity at The Nutrition Obesity Research Center at Harvard Medical School.

'Protein consumption helps with building and repairing muscle and other tissues in the body,' explains Cota. Protein shakes offer many of the same health benefits as other sources of protein.

Some have as little as 10 grams, while others offer as much as 25 grams of added protein within only 14 ounces of liquid.

They are popularly mixed up in shaker bottles pre or post workout or may be formulated in pre-packaged cans or bottles. Protein shakes are beverages in which protein powder has been added. 'Protein shakes can help athletes and non-athletes meet their overall protein intake, but there are a couple things to know before purchasing them,' says Ashley Hagensick, MEd, RD, a sports dietitian at Intermountain Health. Still, the beverages do offer some health advantages under the right circumstances.
