Three Things to Look For When Choosing a Protein Bar
As much as we want to get all of our nutrients from whole food sources, it can be hard to meet protein goals without the use of supplements. Protein bars in particular have come a long way. You used to be limited to a few options that left a lot to be desired in the taste department. Now, every supermarket and convenience store has an entire section dedicated to them.
With that said, the choices can be overwhelming. If you go into this journey without a lot of knowledge, you may not know what to look for and just pick something randomly. Here are three things to look for when choosing the right protein bar for your needs:
1. Sugar Alcohols
Sugar alcohols are not inherently bad. They are used to flavor products while keeping calories low. However, since they are digested differently than regular sugar, they can cause gastrointestinal issues for some people. What's more, different sugar alcohols can cause different reactions. Personally, erythritol is completely fine for me while maltitol is a no-go. Other commonly used sugar alcohols include sorbitol, xylitol, and mannitol.
2. Protein Content
This one may seem obvious, but many snack bars on the market are masquerading as protein bars. A protein bar should have at least 15 grams of protein to make it worth your while. Otherwise, you're getting the majority of calories from carbohydrates and fats, completely defeating the purpose of the protein bar in the first place.
3. Brand Reputation
Dietary supplements are an unregulated industry. It's not uncommon for a protein supplement to not meet label claims when the product is tested in an independent lab. This is the unfortunate reality of supplements.
Larger companies are subject to more scrutiny, which is a good thing for consumers. There is a level of integrity that must be upheld if they don't want their reputation to be tarnished. The bigger risk lies with smaller, up-and-coming brands that may not have the resources to make sure their products are manufactured the same way, every time.
There have even been more cynical instances where brands knowingly put out false labels. A good way to protect yourself is to look for bars that have been third-party tested and certified. Organizations like NSF International, Informed Sport, and USP independently verify that a product contains what it claims to, and in the right amounts. A certification seal from one of these organizations on the packaging is a strong sign that the brand takes quality control seriously.
Choosing the right protein bar doesn't have to be complicated, but it does require a little due diligence. By paying attention to how a bar handles sugar alcohols, confirming it actually delivers a meaningful amount of protein, and sticking to brands with a solid reputation and third-party verification, you can feel confident that what you're eating is both effective and honest.
