low sugar plant based Protein Bars

Whether you dislike sweet protein bars or are cutting back on sugar, we have found the perfect low sugar vegan protein bars for you.

By now, you’re probably familiar with protein bars; it’s an affordable supplement that adds 20 grams of protein to your daily intake as easy as grabbing a snack. But if you’ve tried protein bars before, you’ve probably noticed a common theme: most bars are sweetened and full of sugar.

There are multiple reasons why someone may want a sugar-free alternative. If someone is on a vegan diet, they tend to consume a lot of sugar through fruits. This is why it can be wise to watch your sugar intake.

Another reason can be, that you’re not a sweet tooth. A lot of people actually prefer savory over sweet. And since most protein bars tend to be sweet, it can actually be very hard to find the right protein bar.

This is why Boston Rock Gym has created a list of the best low sugar protein bars. We actually have had them all ourselves and love them individually! Since there are a ton of protein bars out there, we couldn’t test them all. So please let us know if you have a contender for these five protein bars.

Things You Need to Know Before Buying Low Sugar Vegan Protein Bars

best plant based protein bars

With countless vegan protein bars manufacturers and brands available in today’s market, it may be challenging to pick the one that will suit your needs best. We want to help you with this choice, so we have put together a brief list of guidelines you should follow to get the best value for your money’s worth.


When it comes to labels, it is important to know that plant-based and vegan are not the same things, and protein bar manufacturers often like to use protein-heavy dairy ingredients like whey and casein in their bars. Just because the main protein source of the bar is plant-based, it does not mean that all the protein is, so check the labels carefully.

Sugar Levels

Some plant-based protein bars contain more sugar than others. The sugar-to-serving ratio can often be so high that it can mess with your blood sugar levels and even cause weight gain, so again, make sure to read the manufacturer’s labels carefully and check just how much sugar their bars contain.

It is also important to note that even natural sugars and sweeteners like agave syrup, agave nectar, and stevia can lead to unhealthy spikes. Pick a bar with 10 grams of sugar or less, and avoid bars with sweeteners listed among the first three ingredients.

best vegan protein bars


Added oils, even the healthier ones like canola, are not sources of healthy fats the way almonds, coconut, flax, hemp, chia, and other whole nuts seeds are. This is due to the fact they lack the benefits of the healthy vitamins, minerals, and fiber that these whole food fats contain.

Protein Amount and Where Does It Come From

Unless you are a professional athlete that prepares for his next big game or marathon, you should be very careful about your protein intake. The current recommendations for daily protein intake are 0.36 grams per pound of body weight.

Most recommend picking protein bars with 8 to 10 grams of protein for snacks and 15 to 20 grams if you want to use protein bars as a meal replacement. You should also ensure that the protein in your plant protein bar has a complete amino acid profile, and the best ones for this are:

  • Pea protein
  • Sprouted brown rice
  • Chia seeds
  • Spirulina Hemp seeds

It is important to know that pea protein and chia seeds contain lectins, which are considered unhealthy for some individuals. You should also avoid heavily processed soy proteins since they are the source of GMOs.

best Taste Protein Bar


You should opt for a bar with a carb-to-fiber ratio of 4 to 1 or less. Take the total number of carbs on the nutrition label, and divide it by the amount of fiber listed. In case the total is four or less, you have found a quality bar that will serve your purposes.

Ingredient Quality

Ingredient quality is one of the essential things you need to consider before opting for a low-sugar vegan protein bar. Look for bars that are minimally processed and limit artificial flavors, sweeteners, and preservatives. This way, you will get the healthiest product available.

Frequently Asked Questions

vegan protein bars

1. What are the characteristics of vegan protein bars?

Traditional protein bars often use whey protein from dairy, while vegan protein bars source their protein from plant sources such as peas, brown rice, beans, nuts, and seeds. Also, vegan protein bars avoid animal-derived products like eggs or honey.

2. Are vegan protein bars healthier than traditional ones?

The healthiness of a protein bar depends on multiple factors, including caloric value, protein, added sugar, fiber, and ingredients used in the manufacturing process. To put it simply, you should opt for a protein bar that meets your specific lifestyle or dietary requirements.

3. Why are ingredient ratios important?

The first thing you need to know is that these ratios are not particularly important if you are just looking for a healthy snack. However, if you follow a keto lifestyle or want to lose some weight, these ratios become highly important to your success or failure. These ratios determine if the bar is truly ketogenic or if it can help you meet your weight loss goals.

4. How many grams of sugar should a protein bar have?

Although the maximum permissible limit of sugars can be up to ten grams, the average sugar content in a protein bar ranges between six and eight grams. Nevertheless, you should opt for a bar with the lowest possible sugar content and look for the one with natural sweeteners to make a healthier choice.

5. Are vegan protein bars gluten-free?

This is something that entirely depends on the ingredients and the type of protein you want to opt for. Gluten is a general name for the proteins found in wheat, rye, and barley, and it can be suitable for the vegan diet, so make sure to read the manufacturer’s description of the product, as most of them specifically declare that their product is gluten-free.

6. When is the best time to eat a protein bar?

Although you can eat protein bars any time of the day, they are especially helpful when you require protein for an energy boost on the go. They make a quality snack and help you bridge the gap until your next meal. You can also use them as a meal substitute when you do not have time or access to a nutritious and well-balanced meal.
