Best Protein Bars 2018 – Top 10 Nutrient Packed Snacks For Energy

Full Disclosure

There are many reasons that people choose to eat protein bars. For some, they help to meet protein goals that are required for successful workout results, for others they are a healthy snack that helps to fill them up so that they don’t snack on other, less wholesome snack options. Some people like to take them along as a snack when they are traveling, hiking, or otherwise out and about and need a quick and easy energy source.

Top 10 Protein Bars

Whether your goal is to lose weight, grow muscle, or just keep a quick and easy snack in reach, there are a wide variety of protein bars designed for your specific needs. Here we have ranked the 10 most popular protein bars based on our review of their true quality.

1. Clif Builder’s Bar

The Clif Bar has been a popular protein bar product for a very long time now, and there was once a time that it would have graced our list. However, due to the current market opinions of unnecessary sugar, poor Clif got the boot.

The same brand that makes the Clif bar does make other products though and the Builder’s Bar does make the cut, although just barely. It contains 20 grams of protein which is a very good and impressive amount, but unfortunately, it also contains 22 grams of sugar and only 2 grams of fiber. While this product does offer more than enough protein, it comes at a sugar price that is just too steep to pay.

2. KIND Bars

KIND Bars contain significantly less sugar, but they also contain less of pretty much everything else. With only 9 grams of sugar to speak of, they also only have 7 grams of protein. They do have more fiber than the Builder’s Bar with 2.5 grams, but there just isn’t enough of anything important in this bar to do what a protein bar is meant for.

3. Larabar

Larabar puts pretty much all of their eggs in the all-natural basket, so to speak. They build all of their bars with real fruit and dates, and they don’t use a single artificial ingredient. This makes their bars very healthy, but they’re also very heavy in carbohydrates.

Each bar has as much as 16 grams to 19 grams of sugar, though it is important to note that all of these sugars are from fruit and not a bit of it is from added sugar. It’s pretty low in protein for a protein bar at only 4 grams to 6 grams each, depending on the flavor.

4. thinkThin High Protein Bars

thinkThin isn’t just a protein bar for snacking or working out; this one is for replacing entire meals. It’s marketed as having 20 grams of protein with no sugar, which sounds a bit over the top. In reality, each bar contains a whopping 21 grams of sugar alcohols and absolutely no fiber. This bar has tons of protein to offer, but it’s far from the healthy option it claims to be and isn’t likely to fill you up like a meal should if it doesn’t have any fiber.

5. Pure Protein Bar

The Pure Protein Bar provides a massive dose of protein and has a ridiculously low amount of sugar. For most people searching for a great protein bar, this fits the bill pretty darn well. Unfortunately, they can achieve this only because they use a ton of artificial sweeteners. If you’re not a fan of huge doses of sugar alcohols, then you probably want to choose a different option.

6. OhYeah! Nutrition ONE

The Nutrition ONE bar gets its name from the fact that each bar contains only 1 gram of sugar. Most bars with such low sugar content are also low in everything else that matters, but this product provides 9 grams of fiber and 21 grams of protein, which is exactly the kind of balance that most people are looking for in a protein bar.

OhYeah! achieves this by using a 10 gram serving of sugar alcohols and a heavy-handed amount of saturated fat to make every bar taste good, which might not be what you’re looking for, especially if you want your protein bar to be healthy in its own right. If sugar alcohols and saturated fat don’t bother you, then you may decide the product is a good choice for your needs.

7. Epic All-Natural Meat Bar

The entire purpose of protein bars is to provide a quick and easy source of protein that you can take on the go. After all, most meals that are high in protein aren’t very portable. Surprisingly enough, it wasn’t until Epic created their All-Natural Meat Bar that anyone bothered to try getting that protein from the most obvious source.

This bar is made with preserved lean meat that is seasoned with various spices and packed with chia seeds. It provides 15 grams of protein and contains absolutely no sugar. The only real downside it the fact that it also contains no fiber, so if that’s something that’s important to you in a protein bar you should probably keep looking.

8. RXBar

RXBar went in an entirely different direction with this product than anyone else has before. They basically rebuilt the idea of what a protein bar should be as if one has never existed before. This bar only has 6 ingredients, which are sea salt, chocolate, cashews, almonds, egg whites, and dates. The combination provides 15 grams of sugar, which is a bit high but all of it is natural, 12 grams of protein, and a massive amount of fiber.

9. Optimum Nutrition Opti-Bar

This protein bar is designed specifically for bodybuilders, so it focuses on being a carb lean source of massive protein doses. It does a pretty good job of that, and with each serving, you get 20 grams of protein, 10 whole grams of fiber, and just 1 gram of sugar. That’s pretty impressive.

It’s also the first product on our list to achieve this sort of balance without using massive amounts of sugar alcohols. The method it does use is an ingredient called isomalto-oligosaccharide, which is another 0 calorie sweetener used as an alternative to sugar. It’s up to you whether or not you care that this ingredient is used.

10. NuGo Slim

This bar from NuGo is probably the best option we could possibly find on the market. They are able to keep their carbohydrate count low, and they don’t have to throw in a ton of sugar or artificial sweetener to do it. Instead, they use chicory root as a natural sweetener, along with just a smidge of chocolate.

Every NuGo Slim bar has only 2 grams of sugar, but 7 grams of fiber and 17 grams of protein. This is a pretty great provision for a product that also doesn’t contain any added sugar or artificial sweeteners.

Benefits And Side Effects

Protein is a vital nutrient for anyone who wants to lose fat or gain muscle. Ideally, your sources of protein would come from homemade meals that a fresh-cooked and full of lean protein, but most of us don’t have that option. This is especially true for those who are constantly on the go.

This is exactly why protein bars were invented. Most of the companies who made the first protein bars were focused on providing an adequate protein source for athletes, and now the industry has grown to cover a much larger market.

These days, protein bars have 3 distinct common uses, and many products focus primarily on 1 use case over the other 2. Protein bars can be used as a snack that provides a healthy energy source when you’re on the go, as a total meal replacement when you are trying to lose weight, or as a workout supplement to help you gain muscle. The use each bar is best for is most easily determined by the ingredients used to create it.


Any good protein bar is designed for one primary purpose, and that is to provide you with a quality protein source.

Everyone knows that protein helps you to build muscle, and this is such common knowledge that scientific proof isn’t really needed anymore. That being said, this doesn’t mean that the proof isn’t out there, and there are a number of studies that have shown how protein works within the body. The thing about protein that many people might not know is that it doesn’t only work for young people who love to work out. Protein is an energy source that can help anyone who knows how to get the right amount and put it to good use.

One group of researchers from The Netherlands published a study in 2012 that showed how protein could be used to help elderly subjects gain muscle and become less frail. They did this using a combination of protein and weightlifting to put that protein to work.

The protein source used in the study was a 15-gram supplement taken 2 times a day, which is about the same as what you can get from most quality protein bars. If simple exercises combined with regular use of protein bars can help strengthen weak elderly patients, it’s pretty likely to work for your needs as well.

No matter what your reason might be for wanting to gain muscle mass, your method should be fairly similar, and the primary priority of that method should be making sure that you get plenty of protein. This is why it’s important that your protein bar is able to provide plenty of protein without upping the carb and sugar dosage too much.

It’s you’re trying to lose weight then what you will want from a protein bar is a little bit different. You still want to make sure you get the same high dosage of protein, though. Nutrition and Metabolism published a study in 2008 which proved this.

The study followed a group of subjects who were given a protein shake every day and another group of subjects who were given a similar supplement that contained carbohydrates. The group who took the protein supplement was able to lose more fat and retain a higher muscle mass than those who had the carbohydrate supplement. If you want to maximize your results and get to your goal fitness level faster, protein is the way to go.

This might seem a bit counterintuitive at first. It does make very much sense that eating more of anything could help you lose weight. It makes sense that it would help you maintain and grow muscle mass, but how does protein help you to actually lose weight faster?

The biggest reason that a high-protein diet can help you to lose weight is that protein can increase your satiety, which is you’re the feeling you get when your body starts to get full. Many people think that carbohydrates are the best type of food to help you feel full, but studies have proven that proteins will outperform carbohydrate in this right every time.

There was a European researcher who wrote an article about exactly how this works in 2008, but it’s not important to know every scientific detail. The overall point is that protein fills you up faster, and high protein content in your diet can help you to eat less, therefore losing weight.

Protein isn’t the only thing that factors into satiety, though. There is also fiber. Obesity research has confirmed time and time again that the higher someone’s fiber content in their diet is, the more likely they are to weigh less.

Researchers and nutrition experts have been studying the way dietary fiber works in your body to decrease hunger and stave off weight gain for a long time, and they’ve been reporting conclusive results since 2000. All of this means that if you want your protein bar to help you feel full and work as part of a weight loss plan, then you should look for a bar that contains not just a high amount of protein but a high amount of fiber as well.

The last piece to the weight loss puzzle when using protein bars is to also ensure your selection has low sugar content. All of the current research suggests that sugar is the primary culprit in causing the body to gain weight. There have been a variety of studies about the connection between weight gain and sugar intake, both small-scale and large-scale, and they have all shown that sugar is a primary cause of weight gain, as well as the negative side effects that obesity can cause, such as Type 2 diabetes and metabolic syndrome.

The Lancet published a paper by Dr. David Ludwig and some other researchers at Boston Children’s Hospital and Harvard University in 2001 that grew to become very influential, and it found that every added serving of sugar had a measurable effect on subjects. For every serving of a drink that was sweetened with sugar per day, there was a 0.24 kg/m2 increase in their overall mass. The line between healthy and overweight is only a few digits on the BMI scale, so this is a pretty significant finding.

So what is the actual suggested serving of sugar for each person per day? According to The American Heart Association, women should only consume about 25 grams of sugar a day and men should not have more than 37 grams a day. This really puts those protein bars that have as much as 20 grams a sugar in each bar into perspective.

If you are looking to gain muscle mass, you should focus on high protein content. If your goal is to lose weight, then you should keep the protein content high and also focus on high fiber and low sugar. If all you really want from your protein bar is a healthy snack, then it’s safe to assume that the protein bars which are best for weight loss are also the best options for your snacking needs. They will help you to feel full from your snack without pumping a bunch of sugar or artificial junk into your system.

Side Effects

At the end of the day, any good protein bar is no different than any other food. There are really very many side effects related to them because they don’t contain any substances that are out of the ordinary.

That being said, too much of any good thing is going to be bad for you. This is even truer if the product you have selected isn’t exactly top-shelf. If you eat too many protein bars that don’t have enough fiber or have too much sugar, this could have a negative effect on your metabolism. As always, you should carefully monitor how much you are eating and make sure the bar you choose is a healthy one.

If the protein bars you select have a high amount of sugar alcohol, usually because of artificial sweeteners, this could be a problem. Taking in too much sugar alcohol can lead to bloating, stomach aches, and other gastronomic issues.

Kauko K. Mäkinen published a research article in the International Journal of Dentistry that rather graphically details the possible side effects that people can experience if they overdose on sugar alcohols. If you are 1 of the many people who are more sensitive to artificial sweeteners than usual, you should keep this in mind when selecting your ideal protein bar.

Recommended Use

Protein bars really are just food, and how often you should eat them depends entirely on what you want to get out of it. If you’re trying to build muscle, you need to carefully calculate what your daily intake of protein needs to be for you to achieve the results you are looking for, and then you can divide that amount by the protein in your protein bars to determine how many you will need each day.

Regardless of your reason for using protein bars, it is probably best to avoid eating more than 3 of them a day. If you’re taking any more than that, it is probably safe to say that you aren’t getting enough nutrients from other sources, like normal food.

If you are using protein bars to replace your meals to help achieve weight loss, then you shouldn’t take more than 1 or 2 each day. It’s important that you still get good, quality meals every day. No matter how aggressive your diet is, you still need to get real food at breakfast and at dinner. This way you can still get your daily dose of fiber, fruit, and vegetables which are also vital to any healthy diet.

If your only reason for wanting protein bars is to get a convenient and filling snack, it’s not quite as important to track your protein intake. However, you should still be careful not to eat protein bars that are too high in sugar or too low in fiber. If not, you’re basically just eating a candy bar. It’s the protein and the fiber that makes you feel full and satisfied, so without them, there isn’t much point in eating protein bars at all.

Final Words on Best Protein Bars

If you’re traveling or too busy to fix a proper meal, protein bars can be a great snack to help fill you up and give you the energy you need for your day.

The best protein bar products are those that have a good amount of fiber as well as protein without overdoing it on the sugar. The op products can do all of this and also still taste good. This combination can be hard to find, with the actual flavor seeming to be the hardest part to achieve after all of the other pieces have been put into place.

Even though protein bars aren’t medical, you should still be careful not to eat too many of them. Overdoing it on these products is just as dangerous as having too much chocolate, or pizza, or even water. Balance is a vital key to any good life, and also to any good protein bar. may receive a small reward on product purchases using links within reviews.
