Benefits Of Protein Bars: Whey Protein Isolate, Pea Protein, Or Other Protein Sources

Protein bars have great benefits to your growth and recovery while also aiming to keep you full. Benefits of these snacks include:

• Packed with protein: Provide enough protein content to offer growth and keep you full while still allowing for proper digestion (1). This will also aid in muscle building and maintenance and workout recovery from protein like vegan sources, whey protein isolate, or others (2).
• Full of fiber: Keep you full longer and moving regularly which is an important piece for your body to properly function and keep weight off (3).
• Short on sugar (if any at all): Be careful of added sugar and other sweeteners that ruin the health benefits of a good bar and ruin all of your dietary work thus far, especially for certain diets, like those who are vegan.
• Inexpensive and convenient: Don’t break the bank for a protein bar that will only provide some benefits and really look for one that will give you everything you need (and deserve) from a bar.

What To Consider Before Buying

Before buying your protein bar, there are some important factors to consider so you get the best product possible.

Calories

Protein bars should reflect your lifestyle and goals and should not be particularly high in calories. While some may be higher than you would like, if the added benefits outweigh this, consider strategically putting it in your routine to not hurt your gains.

Protein

It is called a protein bar for a reason and your protein source matters. You want to make sure your bar as ample amounts of protein to keep you full and aid in muscle growth and has as much protein as you would get in a meal. The right bar will have a great balance of macronutrients with a priority put on protein, regardless of source be it plant-based or whey protein isolate, for example.

Sugar

It is important that you enjoy what you eat especially when it comes to these bars, however, if a company just adds sugar then it takes the point away from a protein bar. While you want to enjoy it, it shouldn’t just be a candy bar replacement with added sugar.

Added Ingredients

Made with whole food ingredients, your protein bar should have those added ingredients that work well for all your gains. Fiber and other digestive enzymes are also helpful to absorb these nutrients and not cause any discomfort. Not all protein bars will have this, but it is good to consider for the best tasting options.
