Questions to Consider Before Buying Protein Bars

What is a protein bar?

In contrast to muesli or chocolate bars, a protein bar consists of around 30% protein and therefore fewer carbohydrates such as sugar or fat.

Thus, a protein bar is a healthier snack than traditional bars. However, you should always keep in mind that protein bars vary greatly from one another. Further up in the ranking, we have already presented some protein bars and compared them with each other.

Why should I eat protein bars?

Basically, the “why” question depends on your goal. Do you want to lose weight, eat healthier or rather gain mass?

In general, if you want to lose weight, it is best to choose a protein bar that is low in sugar and calories. Protein bars may or may not be better than other weight loss snacks.

It is the same when you want to build up mass. Pay attention to the protein content and the ingredients, in this case a small amount of calories will not be so important to you, but the protein content is all the more important.

Protein helps you, regardless of your goal, to maintain your muscle mass and build it in connection with training.

Most protein bars are specially designed to combine many important nutrients in this snack and are therefore also a good dietary supplement.

I just want to say briefly that, as I said, protein bars serve as a dietary supplement, so as the word suggests, they should be used in addition to a healthy diet and exercise.

Protein bars are therefore not a miracle cure but should rather be viewed as little helpers.

How useful are protein bars anyway?

Despite the very obvious advantages, it is also important to question whether protein bars are useful or unnecessary.

  • Protein bar ~ 30 g
  • Harz cheese ~ 30 g
  • Tuna ~ 24 g
  • Chicken breast ~ 20 g
  • Egg ~ 13g

Humans need an average of 0.8 g per kilogram of body weight. This amount of protein can easily be supplied through a balanced diet.

Overall, a normal consumer with a medium level of activity, i.e. about two to three exercise units per week, is assumed.

However, protein bars can be helpful if, for example, you do not have enough protein sources due to your diet and therefore do not get the required amount of protein. In this case, reaching for a suitable protein bar can be a good alternative or supplement.

What types of Protein bars are there and which one is right for you?

As mentioned at the beginning, different protein bars are suitable for different goals. There are the following categories:

  • Protein bars to build muscle
  • Protein bars for weight loss
  • Protein bars for allergy sufferers
  • Vegan protein bars

The main differences here were the compositions of the nutrients. Some get their protein from milk protein or whey protein, others from soy.

Depending on your goal, some nutrients are more important than others. That’s why we’ve made a rough subdivision in which, hopefully, everyone can classify themselves.

Protein bars to build muscle: Advantages & Disadvantages

Protein bars help you achieve your goal, so if your diet doesn’t get you the protein you need, they’ll help you out.

Because protein bars are now available almost everywhere, they are easily accessible and practical. This is particularly helpful in stressful times when you don’t have time for a healthy snack or a healthy diet.

At this point it is important to mention that before consuming protein bars, you should work out how much protein your body actually needs for your goal. In many cases, a healthy, balanced diet already covers your daily needs.

Should you discover a lack of protein, the question arises when it is best to eat the bar.

Usually, the manufacturer’s website provides information on when it is best to consume each bar. Otherwise the packaging often says “3 after”, which means three hours after exercise.

In general, as always and in connection with additional protein intake, drink plenty of water. This helps your kidney filter out harmful and excess substances and keep you healthy.

In general, we recommend eating the protein bar after exercising. A simple advantage would be, for example, that you should empty your memory during exercise and replenish it with high-quality proteins and carbohydrates after training.

A protein bar before exercise can provide you with the extra energy you need during exercise. Here, however, it makes sense to eat the protein bar no less than half an hour before the exercise session and to choose a light bar that is not heavy on the stomach.

Protein bars for weight loss: Advantages & Disadvantages

Whether a protein bar is useful for losing weight depends on the diet and the protein bar.

For example, many protein bars are high in carbohydrates and sugar, which help maintain and build muscle after a workout. However, if a bar is high in carbohydrates, it is also high in calories.

So if you are counting your calories, be sure to pay attention to the calorie information on the protein bars, as they are often higher in calories than you would expect.

There are also special low-carb protein bars, i.e. those with a lot of protein but little carbohydrates, so they also have fewer calories and are good for your diet.

In principle, protein is also important when losing weight, as it helps you not to reduce muscles when losing weight. Because muscles help you lose weight and the more muscles you have, the more calories your body burns.

Also, progress on the scales should come from excess fat, not from dwindling muscle.

Protein bars for allergy sufferers: Advantages & Disadvantages

Many protein bars have ingredients that are not tolerated by allergy sufferers. Especially if you are not allowed to eat lactose, nuts or soy, it is difficult to find the right bars.

It is therefore important to always carefully study the ingredients on the bars and also to be attentive to the flavors. Because nougat, for example, consists of an essential part of hazelnut.

As an allergy sufferer, you should pay attention to the ingredients of protein bars, as most bars can contain traces of nuts.

For experienced people this is probably not a problem, but rather the addition “may contain traces of nuts and legumes”. This is usually found on most products that are basically without nuts but are produced in the vicinity of other bars that contain nuts.

Vegan protein bars: Advantages & Disadvantages

There are now many protein bars that are suitable for vegans. Among other things, milk and other animal proteins are avoided.

Vegan substitutes are for example soy or rice protein. Furthermore, so-called superfoods such as chia seeds are an additional plus in the bars.

Purchase criteria: Use these factors to compare Protein bars

In the following we would like to show you the factors you can use to compare and rate protein bars. This will make it easier for you to decide whether a particular protein bar is right for you or not.

In summary, these are:

  • Nutritional values / protein content
  • Taste
  • Ingredients
  • Price
  • Availability
  • Vegan / allergies

Nutritional values / protein content

The most important consideration when you decide to buy protein bars is the protein content. In general, the protein content should be at least 15 g or 30%. How high the calories of each protein bar is depends on the purpose for which these special bars are made.

The optimal carbohydrate and protein distribution also depends on your goal and cannot be answered across the board. However, it is not always good if a bar is low in sugar or other carbohydrates, because these can be very helpful in refilling empty stores.


Immediately afterwards, taste is on the list of priorities. Because if the protein bar is practical but doesn’t taste good, you probably don’t want to eat it or even buy it again.


Basically, protein bars are now available in all sizes and flavors. It is then only a question of preferences and possibly intolerances.

Since there are already almost unlimited possibilities of flavors on the Internet, you only have to find your way around this abundance and probably also try several more until you come to your favorite.

To get started, check out the nearest grocery store. There is a smaller but much more manageable amount there and you can try out individual protein bars more easily.


In this case, the fewer the ingredients, the better. So it’s best to always check the back of the bar and the ingredients before buying. Above all, this is also important because protein bars do not have to meet any requirements to be allowed to be called protein bars.

Otherwise you should pay attention to the sugar content and also to ingredients that you don’t know how to pronounce.

Since protein bars often do not contain normal sugar, this is often replaced by sweeteners and artificial sweeteners. Natural sweeteners made from dates, syrup or stevia would be better.


The price ranges are very high in this case. The price ranges depend heavily on the quality and quantity.

When it comes to quality, the main focus is on the ingredients and processing. When it comes to quantity, the price is often determined by the magnitude. In a pack of 12, a protein bar is often cheaper than buying it individually.

As a little tip, if a product smiles at you, check whether an influencer has a discount code or wait until there is another promotion. This can often save a few percent.


You can get protein bars as such almost everywhere these days. Whether in the supermarket, drugstore or gym, almost everyone has a selection of protein bars.

However, if you are looking for something special, you may only get it on the Internet. Many manufacturers only sell their snacks via their website or platforms such as Amazon.

Vegan / allergies

There are now many protein bars in which the protein does not come from animal proteins. Instead, vegetable proteins are used. Plant sources could for example be soy, nuts or hemp.

Both vegan and other protein bars can often contain nuts and other allergens.

Facts about Protein bars

How Healthy Are Protein Bars Really?

How healthy protein bars are depends on the ingredients and the amount you eat. Many protein bars are just called protein bars even though they are more like sweet treats. You can recognize this by the amount of sugar, the other nutrients and the ingredients.

Basically, you should look for a bar with little sugar, a lot of protein and manageable, pronounced ingredients.

If you’re not sure which protein bar delivers what it promises, read reviews or recommendations online. This will give you a good overview.

How many protein bars can you eat per day?

Basically there are no restrictions. However, as with anything, you shouldn’t overdo it. A protein bar or two a day will not do you long-term harm, but you will simply eliminate the extra protein that goes beyond your daily needs.

So if you eat too many bars a day, they will no longer help you with your goal, but are just more expensive and often high-calorie fun.

So it’s best to work out how much protein you need per day and what you get in through your diet, you can then add the difference with the protein from the bars.

What innovative protein bars are coming?

Insects. Crickets, for example, contain up to 77% protein, are low in fat and calories, are low in carbohydrates and the human organism can convert up to 95% of proteins into protein.

These small animals are therefore optimal sources of protein. These are tainted with different flavors and produced in bars. They work well as an alternative to traditional protein bars.

Another advantage is that barbecues are environmentally friendly, they take up little space and water and hardly cause any CO².
