Boost protein intake on-the-go with the right amount and type

If you're on the hunt for a protein-packed bar, it can be challenging to select the best option as the number of products seems endless. Particularly for men—who may require more protein than women—protein bars can be tricky territory. Many bars on the market contain poor-quality proteins, artificial sugars, or additives that will slow you down rather than power you up. Carefully reading the packaging can be helpful to decipher what bar will help you to meet your protein goals and what's comparable to a candy bar.

Protein bars are a convenient way to boost nutrition when you're on-the-go and don't have adequate time for a well-balanced meal. It's essential to look closely at the protein content, protein type, and sugar levels of each bar. If you have a particular dietary restriction, there are bars for every dietary need, including keto, paleo, nut-free.

What to Look for in a Protein Bar for Men

How Much Protein:

It is suggested that the average male who is moderately active and healthy consume anywhere from 0.8 to 1.0 grams of protein per kilogram of body weight per day. For those who are very active or looking to build muscle, the factor increases to about 1.0 to 1.2 grams of protein per kilogram of body weight per day. Once the body absorbs all the protein it can in one sitting, the excess is then stored away as fat, so it's best to have small portions of protein throughout the day rather than a large amount at one time. Considering that a protein bar only accounts for a small portion of your daily protein intake, you should look for a bar that contains anywhere from 10 to 20 grams of protein, depending on your needs.

What Kind of Protein:

When selecting a protein bar for a snack or mini-meal, you should look for a bar that contains protein from real food sources (meat, eggs, nuts, seeds, legumes) rather than highly processed ingredients that promise mega high amounts of protein. 

Sugar, Fiber, and Other Ingredients:

It is also important to choose a bar with more grams of protein than grams of sugar, less than 10 ingredients, and at least 2 grams of fiber.


If you're eating a protein bar as a snack, stick with a bar that's about 200 to 250 calories. When you're unable to get in a balanced meal, consider skipping the meal replacement bar and combining your snack-sized protein bar with a quick source of whole, real foods like a smoothie, salad, or sandwich to give you a bit more sustaining nutrition—or about 300 to 500 calories.

Best Overall: Bulletproof Collagen Protein Bar

With 12 grams of protein, only 2 grams of sugar, and a blend of high-quality fats, Bulletproof's Collagen Protein bars take the top spot among protein bars for men. The decadent Chocolate Chip Cookie Dough-flavored bars contain collagen from grass-fed cows, organic nut butter, and Bulletproof's exclusive Brain Octane Oil. With only nine net carbs and 220 calories per bar, Bulletproof's Collagen Protein bars are a fantastic choice to keep men fueled and satiated throughout the day.

Unlike many protein bars on the market that are filled with artificial sweeteners or other subpar ingredients, Bulletproof bars contain only ingredients you can read, including whole foods like cashews, coconut oil, cashew butter, and cacao nibs. They're also gluten-free, dairy-free, and non-GMO.

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 perfect for those moments where you need a snack and are stuck with limited options, which may be a frequent occurrence for men who are constantly on-the-go. 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 or large price tag. 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.

Many protein bars and packaged snacks targeted at men contain highly processed ingredients such as sweeteners, protein powders, and preservatives that may do more harm than good. Even when a bar contains real, whole food ingredients and is classified as vegan, it's common that you can hardly recognize the healthy components in bar form. 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 of the bar. Pumpkin seeds are a great source of stress-reducing magnesium as well as mood and immune-boosting zinc.

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, less than ten 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 Post-Workout: Papa Steve's Raw Foods No Junk Raw Protein Bars

Looking for a bar with some extra oomph after a tough workout? Papa Steve’s No Junk Raw Protein Bars can be consumed as an on-the-go mini-meal or as a satisfying post-workout snack. Depending on the flavor, these bars contain anywhere from 13 to 20 grams of protein from raw whey or vegan protein sources, over 50 percent of the recommended daily intake for fiber, and less than 10 grams of sugar. In fact, the sugar in each bar comes from raw dates and fruit.

Each bar is handmade in Southern California from non-GMO, wheat-free, and soy-free ingredients. They last for 45 days at room temperature, two to three months in the refrigerator, or up to six months in the freezer.

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.

If you're looking for a paleo-friendly, grain-free bar that tastes great and packs a protein punch, Primal Kitchen Collagen Fuel Bars are an optimal choice. Each satisfying bar is made without gluten, dairy, or soy. Primal Kitchen uses nuts, seeds, egg whites, and grass-fed collagen as protein sources to provide 15 grams of protein per bar. Many paleo-friendly bars skimp on fiber; however, these fuel bars contain between 6 and 9 grams of dietary fiber (depending on the flavor) to help keep you fuller longer.

Collagen may be associated with women for its role in strengthening nails and hair, but it's also great for men. If hair and nails aren't your top concern, it's an excellent source of animal protein, especially for men who have trouble digesting whey or other animal proteins. These chewy 230-calorie bars contain only 3 grams of sugar and come in a variety of flavors, including Chocolate Hazelnut, Coconut Cashew, Dark Chocolate Almond, and Macadamia Sea Salt.

Best Nut-Free: Epic Provisions Chicken Sriracha Protein Bar

High-quality nut-free bars can be hard to find especially if you're looking for a bar that's high in protein and light on grains. Choosing a savory meat bar such as EPIC's Chicken Sriracha is an excellent choice, especially for men with dietary restrictions or those who avoid nuts. They're also keto-friendly, gluten-free, and paleo.

This spicy, wholesome bar contains 130 calories and 15 grams of protein from natural chicken. It's Non-GMO Project Verified and contains no sugar. If you watch your sodium intake, it's important to note that one bar contains 750 milligrams of sodium— or 23 percent of the recommended daily value.

Best Granola Bar: Purely Elizabeth Ancient Grain Chocolate Sea Salt Granola Bar

Many granola-based bars on the market contain minimal nutrients and are more like cleverly marketed candy bars rather than nutrition boosters. If you're looking for a great-tasting granola bar that contains nutrient-dense ingredients, Purely Elizabeth's Original Ancient Grain Granola Bar is the best choice. Each bar is sweetened using unrefined coconut sugar, a low-glycemic sweetener that won't cause your blood sugar to spike as drastically as white cane sugar. The satisfying, crunchy bars are made using USDA Organic, non-GMO, and gluten-free ingredients.

Purely Elizabeth Granola bars come in four flavors, including Blueberry Hemp, Chocolate Sea Salt, Vanilla Almond Butter, and Original. The Original flavor bar packs 140 calories, 3 grams of protein, and 6 grams of sugar.

Frequently Asked Questions

  • 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

"Men tend to have more pounds of muscle than females, and to support that, typically have a higher need for protein. For men, I recommend choosing a protein bar that has at least15 grams of protein, 3 grams of fiber, and no more than 3 grams of saturated fat. If using a protein bar as a post-workout recovery snack, a bar in the 200-300 calories range is sufficient for most men."—Melissa Rifkin, MS, RD, CDN
