Protein bars can be the perfect bridge to get you to your next meal as well as a nutrient-dense fuel to replenish tired muscles after a workout. However, a large portion of them are devoid of nutrition and often filled with sugar, sodium, and highly processed ingredients. In fact, many bars on the market don't contain much protein at all.

Choosing a protein bar made from natural protein sources—such as nuts, seeds, and other whole foods—is best for keeping your energy up and intake of questionable processed ingredients down. Depending on your individual needs and preferences, many bars on the market vary in calories, sugar, fiber, and particular allergens if that is a concern. Our nutritionist rounded up the best options available to help you select a nutritious protein bar for your needs.

Here, the best protein bars:

Best Overall: Health Warrior Pumpkin Seed Bars

Health Warrior, Organic Honey Cracked Pepper with Turmeric Pumpkin Seed Bars

Choose bars that use whole food ingredients. Health Warrior Pumpkin Seed bars are as close to whole foods as you can get. Plus, you can see the full pumpkin seeds, which are the number one ingredient, or largest component of the bar. Pumpkin seeds are a great source of stress-reducing magnesium as well as zinc that helps maintain your immune system.

Each Dark Chocolate flavor bar contains 170 calories, 8 grams of protein, and 6 grams of sugar. It checks all boxes: more protein than sugar, fewer than 10 ingredients, and digestion-promoting fiber. If you prefer other tastes, the bar also comes in Honey Sea Salt, Maple Sea Salt, and Dark Chocolate Peanut.

Best Budget: KIND Dark Chocolate Mocha Almond Bars

Thank goodness for KIND Bar’s 5 grams of sugar option. These bars are affordable and available almost everywhere. From drug stores to gas stations, these bars are fabulous for those moments where you need a snack and are stuck with limited options. The crunchy bars are made without genetically modified ingredients and are also gluten-free.

Try this bar if you want a sweet, satiating snack without the extra sugar. One Dark Chocolate Mocha Almond bar packs 5 grams of protein, 170 calories, and 7 grams of fiber. The number one ingredient in the delicious bar is heart-healthy almonds, which have been shown to improve cholesterol levels.

Best for Women: Naturally Clean Eats Vegan Protein Bars

Naturally Clean Eats Vegan Protein Bars

For women, choosing a bar that is satisfying, delicious, and hormone-balancing is key. Hormones affect everything from mood to hunger, so keeping them regulated with healthy fats is helpful to boost energy and general well-being.

In addition to healthy fats, each plant-based bar contains sustaining protein to power women through an action-packed day. The Peanut Butter + Greens flavor packs 7 grams of protein, 220 calories, and 7 grams of natural sugar from dates. It also contains 10 grams of fiber, partially from chicory root, a known prebiotic that supports gut health by feeding the good bacteria in the body.

The easily digestible protein comes from nutrient-dense ingredients such as quinoa, pumpkin seeds, and chia seeds, making this non-GMO, vegan, gluten-free bar an excellent choice for women on-the-go. Plus, the bars don't require refrigeration, so you can stash them in your bag for a healthy snack anytime and anywhere.

Best Gluten-Free: Raw Crunch Bars

Raw Crunch Bars - Organic Dark Chocolate - Box of 12 Bars

If the ideal gluten-free snack existed in a package, Raw Crunch Bars would take a gold medal. These delicious handmade bars are full of wholesome nuts, seeds, honey, and fruit. These raw ingredients are soaked and dehydrated in small batches—rather than being cooked—to maintain the nutrients and enzymes. If allergens such as gluten are a concern, Raw Crunch's facility is gluten-, dairy-, and peanut-free. The bars are free of gluten, soy, dairy, and grains.

The organic bars are full of plant-based protein and fiber from a variety of nuts and seeds. They also contain a critical ingredient that many Americans do not consume enough of—Vitamin E. Vitamin E is an important antioxidant which helps prevent cognitive decline, coronary artery disease, and cancer. One Raw Crunch bar contains 15% of the recommended daily intake of vitamin E, plus 5 grams of easily digestible plant protein, 5 grams of natural sugar, and only 150 calories.

The bars come in a variety of flavors, including Blueberry Lemon, Cranberry Orange, Dark Chocolate, Dark Chocolate Cherry, and Goji Berry.

Papa Steve’s offers a variety of products to satisfy a wide array for consumers, including those who eat a vegan diet, follow a paleo lifestyle, or are highly active.

Best Keto: Primal Kitchen Protein Bar

Primal Kitchen Protein Bar

Finding a keto-friendly bar that is low in sugar and high in real food ingredients can be a challenge. Primal Kitchen's Protein Bars are paleo- and keto-certified, with only 2 grams of sugar and 9 grams of carbs per bar. The five delicious flavors—Almond Spice, Chocolate Coconut, Coconut Lime, Mint Chip, and Peanut Butter—satisfy any sweet snack craving thanks to a bit of honey and monk fruit extract.

Protein from nuts, seeds, and cage-free eggs makes this Primal Kitchen bar a smart snack any time of the day. Each bar contains 8 grams of protein with 16 grams of healthy fats, primarily from coconut oil. The combination of fat and protein helps to keep energy boosted, especially if you follow a keto diet. The smooth, soft texture is decadent, and the convenience of a packaged keto treat is unmatchable.

Best for Fiber: ALOHA Organic Plant-Based Protein Bars

ALOHA Organic Plant-Based Protein Bars

Many bars are lacking in dietary fiber, which helps to keep you satisfied and can help to lower your risk for various chronic conditions, including diabetes and cardiovascular disease. Aloha’s Organic Plant-Based Protein Bars are almost as high in filling fiber as they are high in protein. For example, the Chocolate Mint bar contains 14 grams of protein and 12 grams of fiber, or nearly 50% of the recommended daily intake of fiber.

The high fiber content comes from tapioca fiber, which is an indigestible starch extracted from the roots of the cassava plant. Tapioca fiber is a soluble fiber that can help slow blood sugar spikes from a high carbohydrate intake as well as regulating the absorption of dietary fat and cholesterol.

They're made from whole food ingredients, including brown rice and pumpkin seed protein with no artificial ingredients or stevia. Whether you prefer chocolate or vanilla, there is a tempting flavor for every taste preference, including Caramel Sea Salt, Chocolate Chip Cookie Dough, Vanilla Almond Crunch, and Chocolate Mint.

Best 100-Calorie: Health Warrior Chia Bars

Health Warrior Chia Bars

When you want a small protein snack but don't want a bar with a ton of calories, Health Warrior Chia Bars are an excellent choice. With only 100 calories and 3 grams of sugar, Health Warrior's Chia Bars are the perfect small snack for an active lifestyle. The tasty, convenient bar is ideal for taking with you on the go or for grabbing before a workout when you want something light.

Chia seeds are an excellent plant-based protein source that also contains fiber and heart-healthy ALA omega-3 fatty acids. Research shows that chia seeds can absorb enough water to equal 12 times their own mass. Each bar provides at least half of the recommended daily value of ALA—a plant form of omega-3 fatty acids.

The gluten-free, non-GMO Project Verified bars are filling, delicious, and an excellent choice for kids. With a variety of flavors—including Acai Berry, Chocolate Chip Cookie Dough, Vanilla Almond, Apple Cinnamon, Mango, and Banana Nut—there's something for everyone.

What to Look for in a Protein Bar


The fewer ingredients, the better. Aim to select a bar with fewer than 10 ingredients. When possible, choose bars made from whole food ingredients that you can recognize like nuts, seeds, whole grains, and dried fruit.


When searching for a protein bar, look for a bar with more grams of protein than grams of sugar. Also, consider the source of the protein. If you prefer plant-based or vegan products, a nut or seed-based bar is likely best for you. If you want a higher-protein bar, choose one that includes a protein powder such as whey, hemp, pea, or brown rice protein.


Choose a bar that uses natural sweeteners like fruit, maple syrup, or honey. Aim to select a bar with 10 to 15 grams of total sugar at most. If you have diabetes or are at risk for diabetes, consider using bars with artificial sweeteners. However, be cautious as high doses can cause stomach issues.


Aim to choose a bar with 3 or more grams of dietary fiber.


Protein bars range in calories from approximately 100 to 250 calories. Consider your needs when selecting a bar. If you're choosing a bar as a small snack, you may want a lower calorie option, whereas if you are using a bar as a meal replacement, you may want a bit more.


What is the best time to eat a protein bar?

You can eat a protein bar at any time of the day, but they are especially helpful for when you need a protein and energy boost on-the-go. They make a great snack and help to bridge the gap until you eat your next meal. Protein bars may be used as a meal substitute when you don't have access to a nutritious, well-balanced meal; however, consider your individual energy and nutrition needs, as you may need to pair the bar with something to ensure you're getting enough.

What is the best protein bar to lose weight?

If your goal is to lose weight, consider how the protein bar will fit your daily energy needs. If you're using the protein bar as a snack in a reduced-calorie diet, you may want to make sure that you select a bar with approximately 100 to 200 calories and at least 3 grams of protein and fiber. A protein bar should be used as a tool when you don't have access to fresh fruits, vegetables, proteins, or whole grains.

What Experts Say

"A protein bar is a great on-the-go option for a quick breakfast or post-workout snack when there isn't time to get in a full meal. Athletes may find them particularly helpful after a hard workout or long run when the appetite may be suppressed, and fuel is needed to jumpstart muscle recovery. For snacks, look for a bar that contains at least 10 grams of high-quality protein. For a meal replacement, look for one with a bit more protein—ideally 20 to 30 grams of protein."—Allison Koch, MS, RD, CCSD, LDN
