The Best Protein Bars According To 3 Registered Dietitians

While we don’t eat protein bars every day, we do find them to be a convenient addition to meals or quick snacks we can take with us anywhere. The problem with protein bars is that there are literally hundreds to choose from! If you’ve visited a grocery store lately, chances are you’ve been met with a wall of protein bars and energy bar options to sort through.

In this post, we’re helping you cut through the mass of options by sharing our favorite protein bars we’ve vetted, as a team of registered dietitians, and enjoyed over the years. While we haven’t tasted every single protein bar out there, we have tasted quite a few. Here’s what we recommend, based on taste, nutrition, ingredients, certifications, and protein quality. 

How We Vetted The 8 Best Protein Bars of 2023 

Our best protein bar review started by inspecting ingredients on bar wrappers and websites. We eliminated bars that contained unwanted additives as well as those that have high amounts of added sugar, highly processed carbs, artificial sweeteners, and sugar alcohols (such as erythritol) that leave a yucky aftertaste in your mouth. We focused on bars that contained short and wholesome ingredients that supply energy and a good amount of protein. 

We looked for solid and well-balanced macronutrient content (calories, protein, carbohydrates, fiber, and sugars), as well as those that contain high-quality ingredients and the best protein sources. Most importantly, the bars we selected had to taste good, have good chewy and crunchy textures, and be something we would actually want to eat. In short, we ate a lot of protein bars and inspected a lot of protein bar wrappers to get to these top picks.

A Whey Protein Bar We’ve Loved For Years: G2G

G2G Bars have been a favorite of ours for many years. Due to their higher calorie count and significant amount of protein (18 grams per bar), we use them as a hearty snack or small meal replacement from time to time. These bars contain the most protein of the top picks we recommend in this post.

• Here’s What We Love About Them: These bars are substantial and offer a significant amount of protein, enough to be a big snack, pre- or post-workout fuel, or even a small meal replacement.

They’re gluten-free and made using certified gluten-free oats.

• Other Macros At A Glance: about 300 calories, 14 g total fat (3 g saturated fat), 25 g carbs (4 g fiber, 15 g sugars from honey and brown rice syrup)

One Of Our Favorite Protein Bars: RXBar

You likely see RXBars in many places, which is one of our favorite things about these whole food protein bars. We find these bars to be similar to a LaraBar but with more protein and fiber. We like RXBars as a Paleo-friendly choice, since they don’t contain grains or dairy.

• Here’s What We Love About Them: These bars are made from minimal whole food ingredients, most of which are listed right on the front of the wrapper (egg whites, almonds, cashews, or peanuts, dates, and sea salt). We like that they’re sweetened naturally with dates and have a pleasant chewy texture and many flavors that we enjoy. 
• Grams of Protein: 12 grams egg whites and nuts
• Other Macros At A Glance: 180-210 calories, 6-9 g total fat (1-2.5 g saturated fat), 22-24 g carbs (3-6 g fiber, 13-18 g sugars from dates and chocolate)

• Where to Buy: Direct on the RXBar website, as well as Amazon, Walmart, and Target

The Keto High Protein Bar We Recommend: Epic Bar

The Epic Bar is unique among protein bars, in that it is a meat-based bar. It’s a great choice for people who are looking for a bar that doesn’t contain common allergens, such as grains, gluten, wheat, eggs, nuts and nut butters, or soy. It’s also one of the few keto and Paleo-friendly bars available and very low-carb and low-sugar for protein bars. We love to incorporate these bars as an easy addition to on-the-go lunches and as post-workout snacks. 

• Here’s What We Love About Them: A tasty, savory bar with a very simple ingredient list. The grain-free bars are Paleo friendly and many are unsweetened. Those that do have some sweetness to them are sweetened with apple juice concentrate. The base of the bars is sustainably-raised meats, such as grass-fed beef, grass-fed bison, grass-fed venison, and 100% natural chicken and pork, so the protein source is high-quality protein that contains all essential amino acids, and a great choice for muscle building.
• Grams of Protein: 7-12 grams from sustainably-raised meats
• Other Macros At A Glance: 90-170 calories, 4-11 g total fat (2-5 g saturated fat), 1-8 g carbs (0-3 g fiber, 0-6 g sugars from apple juice concentrate)

• Where to Buy: Direct on the website, on Amazon, and available at many retailers (check the store locator), including Target, and Whole Foods.

How To Choose A Protein Bar

With so many options, it can be overwhelming to find the best protein bar for you. Here is a 3-step process that can help you narrow down your search. 

1. Eliminate bars that have unwanted ingredients. If you want or need to avoid a certain ingredient or allergen, such as gluten, dairy, nuts, or eggs, then start there. Maybe you just don’t like peanut butter, or maybe you don’t want a bar with egg whites or grains. By the process of elimination, you can rule out many bars that have these ingredients. 
2. Set your protein goal. How do you plan to use protein bars in your life? Do you want to have them as an occasional small meal replacement? To help you increase your daily protein intake? As a healthy snack option? If meal replacement is your goal, then look for a bar that contains 15 grams of protein or more. If increasing your protein intake or healthy snacking is your goal, then bars that contain 10 grams of protein or more are good options. 
3. Taste, taste, taste. The final step to finding your favorite protein bar is to taste them! If you like the ingredient list and protein amount of a certain bar, try that brand’s variety pack so you can discover which flavors are your favorite. Only you can decide what tastes good to you. Everyone on our team prefers slightly different tastes and textures in protein bars, and the 8 bars in this post are the top picks that we all liked and agreed upon as good-tasting options.
