Protein bars can be a convenient option for on-the-go snacking. But the large variety of protein bars on the market makes shopping overwhelming. I have reviewed every protein bar on the market so you don’t have to! Check out my top picks below for the best protein bars based on nutrition profile and ingredients.
How to select the best protein bar for your needs
There are a few key ways that protein bars differ from one another. Consider these nutrition differences before you shop and identify what your nutrition priorities are to help narrow down your options.
1. Balanced protein bar vs. protein only
If you’re looking for a balanced snack, the best protein bar will be one that contains a source of protein, carbohydrate, fibre, and fat. If you’re looking for a bar to boost your protein intake only, choose a bar with lower carbohydrates, fats, and with protein as the main macronutrient.
2. Sugar-sweetened vs. non-sugar sweetener
Protein bars are sweetened with either sugar, such as table sugar, honey, or syrups, or non-sugar sweeteners, such as sucralose, sugar alcohols, stevia, or monk fruit. Whether or not non-sugar sweeteners are a better option than sugar remains controversial. There is debate as to the impact of these sweeteners on our hunger & satiety cues, whether or not we overcompensate with more calories or sweet foods later in the day after eating non-caloric sweeteners, and the impact on gut microflora and weight.
In their 2023 guidelines surrounding non-caloric sweeteners, the World Health Organization suggests that in addition to reducing our intake of added sugar, we should limit our intake of non-sugar sweeteners. In short, they concluded that using non-sugar sweeteners in place of added sugar does not seem to support long-term weight loss or disease prevention. This means that simply swapping sugar in your diet for an alternative non-sugar sweetener will not necessarily improve your health.
If choosing a bar sweetened with non-sugar sweeteners, opt for one sweetened with monk fruit or stevia, as these are more natural alternatives to artificial sweeteners. If you prefer bars without non-sugar sweeteners, opt for one free from added sugars, or with less than 7g of added sugar per bar (or as close to this as possible based on what is available to you). I have included options for both of these scenarios in my list below. Note: the exception here is for individuals with higher-than-average nutrient needs seeking high-calorie protein bars as these will almost always contain a higher sugar content.
3. Ingredient list
Some protein bars have a very long list of ingredients with more additives which tend to be more processed, while others contain a shorter list with more whole-food ingredients (ie. ingredients that you would likely use if you were making a protein bar at home). Consider the quality of ingredients used when looking at the nutrition information on each label.
4. Protein source
Variety is best when it comes to protein sources in your diet. Protein bars can help add variety to your diet by including protein sources you may not otherwise consume regularly. For example, someone who typically consumes animal-based protein may benefit from choosing a plant-based protein bar.
When comparing protein bars, keep in mind that the majority of protein in your diet should come from whole food sources and not protein bars. The protein bar you choose will ideally contribute only a small percentage of protein to your total diet. With this in mind, consider the flavour, texture, and overall nutrient profile of the bar to select the option thats best for your overall needs.
10 Best Protein Bars That are Dietitian Approved
A note from me before I get to my top 10 list. I try to keep this post updated, but the protein bar category is constantly changing. Protein bars appear and disappear from the market, and product formulations change. Always check product packaging for up-to-date nutrition and ingredient information before consuming.
I have carefully vetted each protein bar included in this list. Each bar has been selected as “best” based on its ingredients, nutrition profile, and relative to others on the market. By nature, protein bars are a processed food item and are not a replacement for whole foods in your diet. Aim to get protein in your diet from a variety of sources (meat, legumes, etc.), and use protein bars to supplement your diet when this is not possible.
