Importance Of Protein For Growth

Protein is a macronutrient vital for many functions in the human body. Since the body cannot produce protein, we must obtain this vital nutrient from foods. Once digested, amino acids are produced which are the building blocks of protein the body then uses to build and maintain muscle (1), produce blood and connective tissue, and work to keep your body primed for whatever comes its way. The type of protein, whether it be whey, vegan, or some other form, all work to build that desired muscle.

While it is easy to obtain protein from a great whey powder, whether that be a concentrate or an isolate, sometimes we need to get protein from other sources, those sources preferably being whole foods, or better yet, vegan proteins. Yet even still it can be hard for us to make a home cooked meal with our busy schedules and this is where protein bars come into play to really advance our goals and give us all of that protein for serious muscle growth (2). As a vital component for muscle growth and muscle maintenance, protein in whatever form should never be overlooked, especially for workout recovery and a protein bar is a great way to get that nutrition, vegan or not.

Benefits Of Protein Bars

Protein bars have great benefits to your growth and recovery while also aiming to keep you full (3). Benefits of protein bars include:

  • Packed with protein: Provide enough protein content to offer growth and keep you full while still allowing for proper digestion. This will also aid in muscle building and maintenance and workout recovery from protein like vegan sources, whey, or others.
  • 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.
  • 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.

Why You Should Eat Protein Bars For Performance?

Protein bars are simple, tasty, and convenient snacks to enjoy while also adding protein and other nutrients quickly into the body for any lifestyle. It is important to not fall victim to the best looking box or advertisement because its all about ingredients. You need to find the right bar for you as many are flooded with sugar and other ingredients that can really hurt your gains (4). For those looking for vegan options, they do have those as well.

While this may seem like a daunting task, trust us, we get it. We’ve all spent time wandering the isles in the supermarket or health store, or browsing endless pages online searching for the next best thing to elevate our health and fitness. Sometimes there is a diamond in the rough and once we find it, it is game over. But sometimes it takes more diligence than we want, or have time for, and that can really hurt our chances of finding a really great supplement or health food product.

What To Look For In A Good Protein Bar

A good protein will have:

  • Minimal calories: Be sure to look for a lower calorie bar that also has plenty of benefits. They do exist.
  • A quality fat content: Depending on your goals, knowing the fat content can be extremely important. Also, make sure it is conducive to whatever diet you may be on.
  • Clean ingredients: Be sure to look for any harmful additives or just extra junk that you do not want in your protein bar snack, as well as the source of protein like vegan, whey, or others.

At the end of the day, choosing the best bar for you all comes down to preference. What you desire in taste, what you want in texture, and what you seek for your bodybuilding goals. The best part is, you can always mix and match bars and are not tied down to one in particular. Many companies offer a variety of bars for various occasions while you can work to create your own group of different bars to really diversify your palate and your goals (5). Don’t get hung up on trying to find the one perfect bar for you because the truth is there may be more than one that fits your desired goals. In fact, there are more than one and it just takes some work in finding it.

How We Choose

When choosing this list of the best protein bars, we wanted to focus on three things: reputability of the company, taste and effectiveness, and price. Each company should be working for you and the name of the brand matters. We look at those trusted companies who work tirelessly to product the best protein bars around. We also know your bar should taste good and be effective for keeping you full and working on producing more gains. These bars have both of those covered and you shouldn’t settle for anything less. We also know people look for vegan and non-vegan sources and we take that into consideration as well. Lastly, price matters. We know it can be expensive to find a good bar and these above are perfect for all your goals while still being affordable options.
