About Grenade Carb Killa Protein Bars

I’m a fan of the highly popular Grenade Carb Killa bars. However, I have a confession to make:

I ordered these protein bars, not realising; they are not suitable for vegetarians. And yes, you’ve guessed it. I’m a vegetarian, or at least, I was!

In fact, I didn’t realise this until I had eaten half a box of them. So, what did I do when I realised they were not suitable for vegetarians? Made myself sick? Threw them away? Fell to my knees, pounding the floor with my fists while looking up at the sky and crying “why, God, why?!”

No. I did none of those things. I ate them. Yes, there, I said it. I ate the rest of the box. I don’t really need to go on with this review, really, as this should say it all.

I’ve been vegetarian all my life – that’s 35 years. People said it would be bacon, or I’d cave in when I saw a “real steak”. It was none of these things. It was these demon bars, that tasted so bloody good that I had to eat more.

I have another confession to make:

I’ve just placed another order.

What are Grenade Protein Bars?

We know you’re looking for cheap protein bars which taste, well, not cheap.

Aside from being the devil’s food, Grenade Bars are a protein-packed, low-carb snack from the masters of sports nutrition – Grenade. These highly-charged treats will blow your socks off with explosive flavour, dynamite texture, and minefield of flavours. Don’t say you weren’t warned.

In a world where low-carb diets reign supreme, finding sweet, satisfying and authentic tasting snacks can prove tricky. Don’t get us wrong – there are some excellent tasting protein chocolate bars on the market (mmmmmm, markets), but a compromise must be made between carb content and taste. But not anymore… Grenade appears to have detonated the theory that flavour should be compromised when producing low-carb protein bars, and the shrapnel of evidence is their Carb Killa range. Boom!

Carb Killa bars are produced using an “advanced baking process”, which creates a softer and crunchier protein snack. This also allows these low-carb, high protein treats to pack a massive 6.7 grams of dietary fibre per bar.

And if you have any doubt as to the quality of these tasty treats, you will be glad to know that they are Informed-Sport approved and credited.

  • 23 grams of protein per bar (depending on flavour)
  • 214 calories
  • Low sugar
  • Triple-layered protein bar

It is important to understand that these bars are NOT SUITABLE for vegetarians. This is because they contain hydrolysed beef gelatin. Carb Killa bars are also NOT GLUTEN FREE.

Carb Killa Video Reviews

Although we do have lots more info to share in this review, we thought we’d give you a little break from reading so you can watch some independent YouTube reviews which we thought you might find helpful:

Low Impact Carbs

The thing which makes Carb Killa bars so special (according to Grenade) is the volume of low-impact carbs.

Low-impact carbs (polyols) are still carbohydrates, however, they do not raise blood sugar in the way standard carbs do. This means they are allowed on low-carb and ketogenic diets.

Grenade advertises Carb Killa bars as containing just 1.5 grams of “impact carbs”. However, depending on which flavour you choose, you will be taking in anywhere between 13.5 and 16.9 grams of actual carbohydrates.

Flavours Available

With most products, it is easy to pick your favourite flavour. In most cases, even when a company gets it right with some flavours, others are poor or suit a limited selection of people with an acquired taste. But Carb Killa, as you have probably guessed, is different. These protein bars come in a number of flavours (11, to be precise), and they all taste great – seriously, they do! At the time of writing, they are available in these flavours:

  • Banana Armour
  • Fudge Brownie
  • White Chocolate Cookie
  • White Chocolate Mocha
  • Caramel Chaos
  • Chocolate Crunch
  • Cookies & Cream
  • Jaffa Quake
  • Chocolate Chip Cookie Dough
  • Dark Chocolate Mint
  • Peanut Nutter

When to Eat Carb Killa Bars

The important thing to note is that they should form part of a balanced diet. If you’re looking to lose weight, you are likely following a calorie-controlled diet. While calories are restricted, eating two 200+ calorie protein snack is still going to make up a sizeable chunk of your daily calories (for example, if you’re looking to consume 1,500 calories per day, more than 25% of your daily allowance will have been taken).

As per Grenade’s own recommendations, stick to two bars per day, maximum. They understand this is hard, but they also note that they should form part of a balanced diet, not to be used as a substitute.

Carb Killa Safety & Possible Side Effects

Carb Killa protein bars are manufactured using polyols. Polyols are calorie-reduced carbs, which contain around half the calories of sugar. Excessive consumption of polyols might cause gas or laxative effects in some people. For this reason, it is advised not to eat more than two of these protein bars per day.

The factory which makes Carb Killa bars makes other products, too. This means that they might contain small traces of sesame seeds, egg, and nuts. If you are allergic to any of these, you should check with the retailer before ordering. Product recipes, factories, and packaging change on a regular basis, so while this statement might be true at the time of writing, this might change.

Final Words

At Fitness Savvy, we look to make sure all the info on our website is up to date and accurate. However, packaging, item sizes, and nutritional information might vary from supplier to supplier, so please make sure you check the retailer’s website to check nutritional info, flavours etc. Also, you should always read the labels of packaging. Otherwise, like me, you might end up eating half a box of something you shouldn’t be eating!

    I love these bars. The flavours are terrific and these are great as a treat either before or after a workout.

    + PROS: They are suitable for Muslim diets as the beef gelatine used is certified Halal. Great flavours and don't taste chalky/dry/bitter
    - CONS: Quite expensive for individual bars
