6 Best Tasting Protein Bars for Muscle Gain

Protein bars are a fun and tasty way to boost your daily protein intake, but taste and quality can vary, widely.

In this article, I’m going to present and go over six of the best protein bars to buy online today. Hand-picked for their nutrient profile, scrumptious flavours, ingredients, and of course, protein content.

1. Reflex Nutrition R-Bar Protein Bars

Reflex Nutrition R Bar

I’m a big fan of Reflex Nutrition. In fact, their one of my top go-to supplement brands, because of their exceptionally high-quality range of products. The R-bars by Reflex Nutrition are the perfect example – a high protein, high fibre, low sugar, great-tasting protein bar by a leading sports nutrition specialist.

R-bars by Reflex not only offer an extremely nutritious protein bar but a tasty one that anyone can enjoy! This can be attributed to the number of different flavours you can choose from! Let’s dive in and take a close look at some of the outstanding benefits this product has to offer.

  • R-bars are very low in sugar. If you’ve meddled with numerous different supplements and products like this, you might already be aware that many others on the market deliver an uncomfortably high amount of sugar. The high levels of sugar found in products like these will do nothing but tamper with your health and this will in turn work against any fitness goals you have for yourself.
  • This product delivers a high source of fibre. Ahh, fibre, the macronutrient that most of us don’t get enough of. This incredibly essential nutrient is often found in food sources not commonly eaten hence why so many of us are deficient in this nutrient. So, if you believe yourself to be one of the unfortunate people who don’t consume enough fibre, you can feel better about yourself knowing that this product will help bring your levels up.
  • Whey protein is sourced from grass-fed cows! For those of you who don’t know, whey protein, the most popular and anabolic protein source on the planet is sourced from cows’ milk. This is the protein source placed into these protein bars. The balance and purity of nutrients found in the cow’s milk can depend highly on the cow’s diet and since they’re grass-fed, you can be assured that the protein they use for their bars is of the highest quality.

If you decide to go and purchase one of their bars, you should know that their online shop sells their bars in packs of 12. Each pack will set you back around £23. Not only is their product reasonably priced but it’s available in five different flavours, so you know there’s going to be something for you.

All in all, Reflex Nutrition has outdone itself with this highly favourable product. The good quality nutrition found in this bar combined with the lack of sugars and other detrimental ingredients makes this product a product you can trust.

How to Choose the Right Protein Bar

Understanding what is and what isn’t good for our health in today’s world can be very difficult. Some lifestyle factors may be considered healthy through one study while another may suggest the opposite…

Whether it’s through false marketing, desperation for money and or a potentially uninformed seller, there are without a doubt numerous products on the market right now being recommended for their potential health benefits without any hard proof.

This aspect combined with a very unreliable fitness industry makes it incredibly hard to understand what we should and shouldn’t do to further improve our health. With that being said, not all services and products on the market should be deemed untrustworthy.

Some products have been well-known for their health benefits for a long time. Products like these are typically backed up by science and aren’t linked to any negative health effects. One of these products is protein bars!

At first, protein bars were a shadow. Most were aware they existed but most didn’t actively seek them out. Now, protein bars are an actively sought-out treat designed to deliver a reliable source of protein whilst simultaneously satiating that sweet tooth we all possess.

When purchasing protein bars to help meet your goals, you must align your goals with the nutritional profile found in the product. This means if you are hoping to both lose weight and build muscle, you will need to opt for a protein bar with fewer calories and higher amounts of protein.

On the other hand, if you are trying to gain both fat and muscle, opting for a more calorically dense protein bar will prove to be far more effective than a protein bar with fewer calories.

Not only should you align your goals with your nutrition requirements but you should be careful when going with a brand you’ve never heard of. Some brands often fill their products with numerous sugars and sweeteners to have the product taste more fulfilling.

This might improve the overall taste of the product but it could in turn work against your goals or worse, it may even be detrimental to your health.

Summing Up

As stated earlier, understanding what’s good and bad for us through nutrition can be challenging. This can be attributed to several different reasons. For this very reason, it’s important to approach anything nutrition-related with an open mind.

This will help to ensure you don’t make any mistakes when picking out the correct products suited to your needs and desires. With that being said, the protein bars listed above are without a doubt, good quality protein sources you can count on.

They are and have been best-sellers for a long time. This is primarily based on ingredients, affordability, and taste. These three factors alone are enough to have anyone convinced but their benefits don’t stop there.

This very article is comprised of the most popular and most sought protein bars. They each offer a similar array of benefits but like anyone and anything on this planet, they each possess unique benefits. So, whether you are looking to build muscle and gain weight, build muscle and lose fat or perhaps just live a healthier lifestyle through nutrition, the above protein bars will without a doubt help you get there.
