Protein bars have been a staple for decades—and with good reason. “They’re convenient, portable options for snacks and meal replacements,” says Andrea Goergen, MHS, RDN. They can be especially beneficial options for on-the-go snacks, as well as a protein-rich bite before or after workouts. But of course, as with any packaged food, options abound—which is exactly why we asked registered dietitians for their top picks so you can choose the one that works for you.

Ahead, learn more about the best protein bars for women.

What to Look For in a Protein Bar for Women

Protein quantity

As far as the quantity of protein goes, Mona S. Cabrera, MS, RD, suggests aiming for at least 4 grams of protein, but ideally 10 grams or more—preferably from sources such as nuts, seeds, whey protein, pea protein, or egg whites (opting for whole food-based ingredients). 

Fiber content

It’s also important to check the fiber content: “Both fiber and protein help us feel full, which is key for nutrition bars because they’re usually used as on-the-go snacks between meals. Fiber has the bonus of supporting a healthy digestive system, so go for protein bars that have at least 5 grams of fiber,” suggests Tamar Samuels, RD, NBC-HWC.

Sugar content

Make sure the bar you choose isn’t packed with sugar—many have so much sugar that they could easily be called a candy bar, warns Cabrera—or artificial sweeteners, which can often cause tummy troubles.

  • What are the benefits of protein bars for women?

    “If you're trying to lose weight, protein can help keep you satisfied between meals and therefore avoid mindless snacking or overeating,” says Breanna Woods, MS, RDN. 

    In addition to weight loss, protein bars can help with nutrition-specific goals. “If you’re an active individual, a well-chosen protein bar may help you reduce body fat,” says Elizabeth Brown, MS, RD, CPT.” Case in point: A small study in the Journal of Biological Sciences showed that combining consumption of whey protein bars with resistance training over four months helped improve lean body mass.

    Plus, protein bars gone right are convenient, balanced snacks. “Whether you're trying to increase your overall protein intake or you need something to hold you over between meals, a protein bar is easy to take on the go or eat when you're short on time,” says Woods.

  • Do protein bars for women expire?

    They do—and you should go by the expiration date printed on the bar. “Expiration is dependent on the ingredients,” says Kathy LaBella, RDN, ACE-CMES/CPT, a sports nutritionist in Old Saybrook, CT. “Every bar is different, depending on its formula. Bars can also go bad if left out in a high temperature, so it is best not to leave them in your car.”

  • When should you eat a protein bar for women?

    “Protein bars as snacks are great for between meals or can be used to keep your calm your growling stomach if you know your next meal is too far in the future,” says Goergen. “The carbohydrate content of protein bars can provide pre-workout fuel and recovery fuel, in addition to protein for post-workout recovery. If you need a boost to keep you going through an endurance workout, try having a snack protein bar before a workout.”

    “Just beware of the fiber and fat content to prevent GI issues during your run or workout,” Goergen adds. If your post-workout meal is planned for more than 30 to 60 minutes after your workout, consider a post-workout protein bar snack to support your muscles, she adds.  

    Higher-calorie bars can be eaten alone or paired with fruit, vegetables, yogurt, or string cheese as a meal replacement—but only when you aren’t able to prepare a meal. “Protein bars should not be your only meals, so please remember they should be a supplement to a regular meal,” says Goergen. “If you’re dealing with kidney issues, concentrated forms of protein can lead to consuming too much, which can be dangerous for damaged kidneys. And consuming too many protein bars can lead to excessive intake of the vitamins and minerals added to the bars and toxic levels of certain nutrients in the bloodstream.”
