Inside of Carb Kill Low Carb Bar

Delivering over 23 grams of protein per bar, Carb Killa is a high protein bar that has been designed to provide balanced complete sources of protein, while limiting the level of simple, processed refined sugars.

The benefits of protein are well known and the role it plays as a key macro nutrient within the body mean it’s vital we consume enough to meet our goals.[1] In addition to that, the added benefits of a high protein low carb diet are much more widely documented, suggesting they are more reliable way to reduce body fat and improve muscular body composition. [2],[3]

Ideal for those on a low carb diet and avoiding sugar and processed carbs, those wanting to gain lean muscle mass with a high protein, low carb snack, or those on a serious mass gain “bulking” diet, supplementing with other high carb mass gain foods/supplements. #ARMYOURSELF

Solid bar, filling between meals. The white chocolate salted penut is delicious. I would eat it even if it didn't contribute to those sweet gains

I think this is a really solid bar. They utilize sugar alcohols and fibers so the net carbs of these things is extremely low; you can fit one or more into these at pretty much any time of day! There are two downsides though. The first is that most of the flavors aren't particularly great. The Caramel one is not very good and the Birthday Cake was unpleasant. The Chocolate Cream is probably the most solid flavor I've tried so far. The other issue is the cost; these are extremely expensive. If not on sale, I would use another protein bar as the main go to and have a few of these for fitting in protein with minimal carbs.

I have tried so many protein bars over the years and the ones by Grenade are by far my favorite. I don’t want my protein bars to taste like a candy bar where they are overly sweet and that is the reason why Grenade is my preferred bar. Chocolate cream is my favorite flavor with the Caramel chaos being a close second. They used to make an orange chocolate one that was out of this world but for some unknown reason they discontinued it. By far the worst of the flavors is the birthday cake because that one is actually a little too sweet.

Good macros, genuinely so much better tasting than a standard protein bar (trust me I've tried plenty). My one disappointment is that doesn't stock my favourite dark chocolate raspberry flavour, however that doesn't effect the quality of the product (nor the fact you guys sell it cheaper than Amazon) so it's a 10 from me.

I have tried most of these bars and they are incredible! Definitely take takes care of a sweet tooth and macro friendly.

Didn't like the Caramel Chaos bar, it tasted really artificial. Couldn't even eat it. The Peanut Nutter flavor is really amazing, though.

3/10 Jaffa Quake 5/10 Dark Chocolate Mint 10/10 White Chocolate Cookie 10/10 Chocolate Chip Cookie Dough 9/10 Cookies & Cream 10/10 Caramel Chaos 8/10 Peanut Nutter I'm kind of the loner, but I love the white choc cookie. My husband's favorite it Caramal Chaos, hands down. The Cookie Dough is really good too. The only one that I didn't like enough to toss the second half, was the Jaffa Quake. Just not my thing. These are still my favorite bars and are the perfect choice when I'm lowering my carbs and cutting.
