The Best Protein Bars According To A Registered Dietitian (2025)

While I don’t eat protein bars every day, I do find them to be a convenient addition to meals or quick snacks I can take with me 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. That’s why my dietitian colleagues and I wanted to create a list of the best good-for-you protein bars to buy.

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

My Process For Selecting The Best Bars 

This best protein bar review started by inspecting ingredients on bar wrappers and websites. 

I eliminated bars that contain

• unwanted additives
• 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 my mouth 

I focused on bars that contain 

• short and wholesome ingredient list
• high-quality ingredients that supply energy 
• solid and well-balanced macronutrient content (calories, protein, carbohydrates, fiber, and sugars)
• a good amount of protein from the best protein sources. 

Most importantly, the bars I selected had to taste good, have good chewy and crunchy textures, and be something I would actually want to eat in order to meet daily protein goals. In short, me and my dietitian teammates ate a lot of protein bars and inspected a lot of protein bar wrappers to get to these top picks.

Favorite Whey Protein Bar: G2G

• Stand-Out Features: These bars are substantial and offer a significant amount of protein (the most protein of any  bar in this round up), which is enough to be a big snack, pre- or post-workout fuel, or even a small meal replacement. These bars should be refrigerated. They’re certified gluten-free and made using certified gluten-free oats. 
• Grams Of Protein: 18 grams from whey protein isolate 
• Extra Macro Information: 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)

• Average Cost: $2.75/bar 
• Where To Buy: Use code REALFOODRDS to get 15% off when you buy directly from G2G; they’re also available on Amazon

Team Favorite Plant-Based Bars: Aloha Bars

• Stand-Out Features: There’s a lot to love about this Hawaii-based company that also sells protein powder and protein drinks in addition to great-tasting protein bars. The company gives back in many impressive ways, which shine through in their annual impact report. I also love that this company is employee owned, certified B Corp, and Climate Neutral Certified. These bars are free from gluten, dairy, soy, stevia, and sugar alcohol sweeteners. They also offer an impressive 6 to 10 grams of fiber per bar. 
• Grams Of Protein: 14 grams from brown rice and pumpkin seed and seed or nut butter
• Extra Macro Information: 220-260 calories, 9-13 g total fat (1.5-7 g sat fat), 22-26 g carb (6-10 g fiber, 3-5 g sugar from cane sugar, tapioca syrup, and monkfruit)

Best Tasting: Honey Stinger Nut + Seed Bars

• Stand-Out Features: You may know HoneyStinger for its energy chews and gels, but the company also makes some good protein bar options. The company is known for fueling endurance athletes and creating energy products that are sweetened with honey. I especially like the HoneyStinger Nut & Seed bars as a protein bar that tastes so good, a lot like a salted nut roll or candy bar, and has healthy fats. I also like that these bars don’t contain any inulin, artificial sweeteners, or sugar alcohols. The bars also contain added vitamins A, C, E, and D.
• Grams Of Protein: 14 grams from whey protein powder, milk protein isolate, nuts, and seeds 
• Extra Macro Information: 260 calories, 15-16 g total fat (3 g saturated fat), 21 g carbs (1-2 g fiber, 16 g sugars from honey and cane sugar)

My Go-To Bar Of Choice: RXBar

• Stand-Out Features: 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). I like that they’re sweetened naturally with dates and have a pleasant chewy texture and many flavors that I enjoy. I find these bars to be similar to a LaraBar but with more protein and fiber, and they are a Paleo-friendly choice, since they don’t contain grains or dairy. 
• Grams Of Protein: 12 grams from egg whites and nuts
• Extra Macro Information: 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) 
• Flavors: There are 7 flavors of the original RX protein bar. My favorites are Peanut Butter Chocolate and Chocolate Sea Salt. 
• Average Cost: Usually around $2.00/bar. Also, Target offers a Good & Gather Protein Bar that is very similar to the RXBar, which you can often find for a price of around $1.50/bar – I like this option as a lower cost alternative to the RXBar, though the original RXBars have a better, softer texture.  
• Where To Buy: Direct on the RXBar website, as well as Amazon, Walmart, and Target

Nut-Free Protein Bars: 88 Acres

• Stand-Out Features: I love these bars that offer protein simply from seeds without using any protein isolates. They’re a good nut-free option made from a really short ingredient list of whole foods, which is so nice and rare to see in protein bars. These bars are free from the top nine allergens, including gluten, soy, dairy, and nuts. They’re also lower in carbohydrate and higher in fat than other bars. 
• Grams Of Protein: 12 grams from pumpkin seeds
• Extra Macro Information: 260-280 calories, 19-21 g total fat (3.5-4.5 g sat fat), 15 g carb (2-3 g fiber, 7-10 g sugar from maple syrup and brown rice syrup. The bars with chocolate also have cane sugar) 
• Flavors: The protein bars come in 4 delicious flavors, and I like the Chocolate Cherry the best. 88 Acres also makes Seed + Oat bars that have less protein (6 grams per bar) but also taste great – in fact, Jess likes them even better. 
• Average Cost: $2.90-$3.10

A High-Quality Plant-Based Bar: GoMacro

• Stand-Out Features: There’s a lot that I love about GoMacro MacroBars, first and foremost the many certifications they have and the high-quality ingredients used in these bars. Plus, there are 3 nut-free options available for those with nut allergies. These certified organic bars are also certified vegan, non-GMO, soy free, and FODMAP friendly, too. While these aren’t the highest protein bars, they offer a good balance of nutrients and can help you increase your daily protein intake when worked in as a healthy snack or meal addition. These bars were developed by a mother-daughter team, and I love that the packaging is more sustainable.

Top Pick For Keto Dieters: EPIC

• Stand-Out Features: 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. Most flavors are unsweetened and those that do have some sweetness to them are sweetened with apple juice concentrate. Jess loves to incorporate these bars as an easy addition to on-the-go lunches and as post-workout snacks.  
• Grams Of Protein: 7-12 grams from sustainably-raised meats, such as grass-fed beef, grass-fed bison, grass-fed venison, and 100% natural chicken and pork

Easy-To-Digest Crispy Protein Bars: MEZCLA

• Stand-Out Features: I like the light and crispy crunch to these, which is a lot like eating a rice crispy treat, just not as soft and gooey. I find that Mezcla bars digest easily instead of feeling “heavy” in my stomach like some other bars do. I also like that they are subtly sweet and don’t have any funky or chalky aftertaste, since they’re sweetened with just a little cane sugar and tapioca syrup. These 100% vegan bars are gluten free and soy free. Mezcla stands for “mixture” in Spanish.

Things To Keep In Mind

With so many options, I know it can be overwhelming to find the best protein bar for you. Here are the 3 main steps I follow to help me narrow down the 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 14 grams of protein or more. If increasing your protein intake or healthy snacking is your goal, then bars that contain 6-10 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 my team prefers slightly different tastes and textures in protein bars, and the 9 bars in this post are the top picks everyone agreed upon as good-tasting options.
