Our Top Protein Bar Picks

Protein bars can make for easy post-workout fuel and on-the-go snacks. However, not all protein bars are created equal. Here, a registered dietitian who's also athletic trainer certified, breaks down the best protein bars you can buy and what to know about each.

Protein Bar vs. Granola Bar

There’s no formal definition for a “protein bar,” but the numerous bars boasting their protein prowess are not created equal. A typical snack or granola bar contains minimal protein, 2 grams or even less per serving. Some other bars may fall mid-range with 8 to 10 grams of protein per bar. For a bar to provide more substantial protein, look for one with closer to 12 to 25 grams per serving, depending on your needs. Protein requirements vary greatly from person to person; a 150-pound adult requires a minimum of 55 grams per day. Protein requirements for athletes and active individuals will be more generous.

How to Choose the Right Protein Bar for You

Proteins bars can be an ideal choice for post workout fuel, grab-n-go breakfast (with a piece of fruit or a smoothie), or a satisfying afternoon snack. While convenient, protein bars aren’t meant to replace whole food meals. Make these bars part of your pantry and gym bag arsenal to rely on when pressed for time or when in need of an energizing snack to sustain you for a few hours. Look for bars with protein from high quality sources, especially if being used for post workout recovery. Whey, soy, egg and pea, or plant-based blends of protein can all provide the proper balance of aminos acids to support muscle repair. Look for bars with low to moderate amounts of added sugars and be mindful of artificial sweeteners as they can cause stomach upset for some folks. Read ingredient lists carefully to choose the right bar for your needs.
