5 Best Protein Bars for Diabetics
Written by Isaac

Most people don’t appreciate the degree to which diabetes impacts a person’s life. It’s far more than simply having to avoid candy bars and milkshakes.

It affects every aspect of their daily life from what they eat to when they eat to how much they eat. 

They need to plan their workouts carefully and monitor their condition continuously.

They need to watch their starch intake, watch their carb intake, and maybe most importantly, they need to resist the sugar urges that can sometimes seem overwhelming.

The good news is that, as long as a diabetic has kidneys that are functioning normally, they can consume more or less the same amounts of protein as anyone else, which makes diabetic friendly protein bars a smart and healthy alternative to sweets.

Below, we’re going to look at the five best protein bars for diabetics.

Finding great tasting protein snacks without sugar or with a minimal amount of sugar isn't easy but we put our nose to the grindstone and came up with 6 that we feel stand head and shoulders above other diabetic breakfast bars.

1. Editor's Choice: BSN Protein Crisp

While some protein bars are just candy snacks with a few off the beaten track ingredients tossed in, BSN Protein Crisp Bars have thoughtfully created high protein bars that pack a considerable punch while remaining devilishly delicious and true to their roots.

There are 2-5 grams of sugar in each of these bars; a sugar load many people with diabetes will find manageable.  

Plus, its texture and delicious taste will make you feel like it's cheat day without compromising your macronutrients. 

Indulge yourself with BSN Protein Crisp Bars after your workout, or any time for a quick energy boost.

2. Quest Nutrition

Quest Nutrition actually produces a dizzying number of protein, health, granola and other snacks for the health conscious.

Their protein snack variety pack is a good example of all the things the company does right.

That includes providing customers with plenty of flavor options and being mindful of the needs of their target audience.

In this case, their protein bars turn out to be some of the best diabetic protein bars because they provide 12 grams of protein, steer away from most of the starch that can wreak havoc with blood sugar levels and are sweetened with allulose instead of sugar.

Allulose is nearly identical in chemical makeup and flavor to sugar but with only 1/10 the calories.

For the most part we enjoyed all the items in this variety pack although, to our mind, the Coconut Cashew snack could use some work.


  • ​An array of flavors to choose from
  • ​No sugar protein bars sweetened with allulose
  • ​1/10 the calories of real sugar
  • check
    ​Great pre-workout for diabetics


  • ​Texture may not be for everyone
  • exclamation-triangle
    ​A few flavors don’t work so well

3. Kind Bars 

Kind Bars have zero refined sugar and are completely free of wheat, dairy, gluten, and genetically modified organisms.

They’re as close as you’re going to get to completely ‘clean’ protein snacks and your body is going to appreciate that. The simple natural ingredients are combined with dried fruit and/or honey to provide a range of wonderfully well-rounded flavor experiences.

Plenty of thought and care went into the making of these diabetic breakfast bars and the results speak for themselves.

Be aware though that the different flavored snacks contain different types of nuts so if you have allergies, you might want to check the label before you buy anything. 


  • ​Available in a wide variety of flavors
  • ​No genetically modified organisms
  • ​Great texture and equally great taste
  • check
    ​Sugar from honey and dried fruit ingredients


  • Not as high in protein as others

4. NuGO Slim

While some protein bars are really just candy snacks with a few off the beaten track ingredients tossed in, NuGo Slim Brownie Crunch bars have thoughtfully created high protein, virtually sugar-free bars that pack a considerable punch while remaining devilishly delicious and true to their roots.

There are 2 grams of sugar in each of these bars; a sugar load many diabetics will find manageable. 

Plus, it helps that there isn't any high fructose corn syrup lurking here that could really mess up blood glucose levels.

The dark chocolate coating makes all the difference flavor wise (but it's a flavor accent, not a foundational ingredient), while the 9 grams of fiber will help you feel satiated.


  • ​Available in raspberry truffle, dark brownie crunch and roasted peanut
  • ​Only 2 grams of sugar per bar
  • ​No trans fats or high fructose corn syrup
  • check
    ​Real chocolate coating


  • ​Can be challenging to find

5. RX Bar

The RX Bar may be just what the doctor ordered for diabetics looking for sugarless protein snacks that also provide a bit of a pick me up during the long day.

Like some of the other protein snacks without sugar on our list the RX Bar is also without GMOs, dairy, soy, gluten and artificial preservatives.

RX Bars have the added benefit of being Kosher and that's welcome in a protein landscape where such considerations are often swept aside.

RX Bars utilize 5 mg of caffeine to produce the aforementioned ‘pick me up.'

That's enough to put some wind in your sails without making you feel jittery. Like some of our other snacks though, if you have nut allergies, you'll want to be careful.


  • ​Consistently delicious no sugar protein bars
  • ​Produced in certified Kosher facility
  • ​5 mg caffeine per bar for energy boost
  • check
    ​Subscriptions available


  • ​Those with nut allergies may want to steer clear

6. Kashi TLC Chewy Granola Bars

Kashi TLC Chewy Granola Bars are not as high in protein as some of the other items on our list - but they are truly delicious, contain plenty of fiber, and steer clear of blood glucose red flags like high fructose corn syrup and, of course, sugar.

What they do contain is plenty of whole grains, sun-dried fruit, dark chocolate, and roasted nuts.

They're free of gluten, soy and artificial ingredients and just one is likely to satisfy your appetite for something sweet without sending your blood glucose levels into space.

​Choosing ​The Best Protein Bar for Diabetics

woman holding a snack bar

As long as the diabetic understands that protein bars are not completely risk-free (some contain starches and other ingredients that can cause a spike in blood sugars), then any of the outstanding, well-balanced, high-quality diabetes bars profiled above should fulfill between-meal cravings.

​These tasty snacks also help maintain stable blood sugar and energy levels.

​When choosing the best protein bar, ​we ​look for quality natural ingredients, outstanding taste, nutritional value, and bars that don't try to slip sweeteners past the unsuspecting. You should too. (1)

Important: Always read the label carefully, look for 5 to 15 mg of protein (the more, the better generally), and steer clear of artificial ingredients, avoid high fructose corn syrup and don't forget to enjoy.
