Choosing the Best Protein & Nutrition Bars – Top 10 Brands

Best Protein Bar Brands

While exercise science and its various fields certainly are important, one of the most overlooked aspects of maintaining a healthy lifestyle is the psychology and development of habits that produces success over time. Unfortunately, there is no magic formula to being fit and achieving our best possible state of wellness; rather the best solution is to be consistent over time, and just as importantly to have habits set up for us to succeed.

No matter how fit a person may be, when temptation and hunger strike, if the only options are bad ones, they will likely give in at some point and splurge on a candy bar or some other vice. Over time, this can lead to long term issues and detract from our goals of high performance.

Thus, in order to combat decision fatigue and our limited will power, we must have healthy options available for energy boosts and hunger abatement, and that is where having a great protein bar option is crucial. protein bars vary widely in their true efficacy and use, but a quality protein bar can provide protein, carbs and fats and help us to fight off cravings or resist the urge to impulse buy in a pinch.

Psychologists have found that we as humans have limited cognition; in other words, our brains have a limited amount of willpower, and no matter who the person is, when we have to make decisions, especially in an impaired state, such as when we are hungry and pressed for time, we tend to opt for poor choices.

For example, if you haven’t eaten all day, have to run to a meeting or appointment but know you need some sort of energy boost, if candy bars are the only thing available you will probably opt for a candy bar. We can prevent these types of situations by investing in protein bars and having them prepared so that when we need quality nutrition quickly, we have it ready.

In this guide, we’ll break down exactly what makes a good protein bar, what to look for and the best products on the market today.

What Are Protein bars?

Protein bars are almost exactly what they sound like, they are bars that offer nutrients in varying forms and amounts. However, this can vary widely, and many so-called nutrition or protein bars are in fact much closer to traditional candy bars than sources of actual quality nutrition. protein bars are portable snacks that ideally deliver protein, carbs, and potentially other nutrients with minimal sugar, cholesterols, and artificial ingredients.

Common Ingredients in a Protein Bar

The most common ingredient in protein bars will generally be protein. More importantly in many cases, is the type of protein and the source it comes from. Protein powders take many forms depending on the initial source. The most common form is whey protein, which originates from dairy products, thus those with lactose intolerance have to audible to other options.

While whey is the most popularly used form, there are many other options such as casein, vegan, soy, and more. Whey is without a doubt the most popular and used option on the market. Whey can be further classified based on its source and manufacturing as well. For example, just as many users prefer beef that has been grass fed or has not had any synthetic hormones injected over time, whey protein comes from the same source and many whey products will specify whether the source of the whey was grass-fed or hormone free.

Most protein bars will tend to also include a wide variety of healthy ingredients, which can range from vitamins and minerals, raw and organic food sources, nuts and seeds and more. The list is likely too exhaustive to list in its entirety in one paragraph, however some of the key items to look for will be how much sugar a bar contains, whether it uses artificial flavoring and preservatives and if so how much, the macronutrient breakdown (Protein, Carbs, Fats) and what other ingredients are included such as vitamins and minerals. Depending on your preferences and what you are specifically looking for in a protein bar will determine which of these factors is most important for you.

Precautions and Side Effects

Side effects from protein bars are generally non-existent or at worst mild as long the recommended dosage is followed. That is a critical component of using protein bar supplements effectively, however, as the recommended dosage is what should be consumed and over-reaching for more can have side effects.

Side effects from protein bars, especially those with an excess of protein, may include bloating, digestive issues or overly dark urine, indicating a surplus of protein in the body. Most of these side effects tend to occur only when the recommended dosage has not been followed, thus the reason the recommended dosage is crucial.

In addition, if you have any particular food allergies or issues such as lactose intolerance, this will affect which protein bars make the best choice; if you have these issues or are not sure then consulting a medical professional is advised. Overall, protein bar supplements are generally considered safe and effective as long as the recommended guidelines and dosages are followed. If you are not sure if they are safe for you consult your medical professional.

How to Pick a Good Protein Bar

When choosing a protein bar supplement there are a variety of factors to take into account. Your personal preferences will play a major part in finding the right selection for you, for example if you prefer a bar with lots of protein to help build mass or something lighter that gives you more energy without the extra bulk.

Some protein bars will skew towards a specific demographic or training goal, such as gaining mass or putting on lean muscle; your personal goals will need to align with the stated purpose of the product in order to see the best results.

Flavor is of course important and not all protein bars are particularly tasty, you’ll want to search for an option with a flavor you generally like to make the supplement more palatable and easier to use.

Finally, price and budget are a factor as well. When cross-referenced with your other needs, the best option will need to fit into your budget, and while you generally may get what you pay for, there are some very effective protein bars that won’t break the bank.
