Key Benefits

Following on from the global success of the iconic Carb Killa® bars, Grenade® has developed Carb Killa® Shake.

Carb Killa® Shake is a smooth and creamy high protein drink with under 200 calories* and is seriously indulgent. With 25g of protein and 7.3g* of carbs, Carb Killa® Shake is a convenient way to consume additional protein between meals without unwanted calories or carbs. Initially in 3 delicious flavours, this thick and creamy shake is as technologically advanced as the bars and can be consumed throughout the day. Informed Sport Registered.


Delivering 25 grams of protein per shake*, Carb Killa® Shake is a high protein treat that has been designed to provide balanced complete sources of protein, while limiting the level of simple, processed refined sugars. Unlike many other shakes / smoothies, Carb Killa® Shake is unique in the fact it is low in carbs. 

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]

*Protein content depends on flavour. 

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.

    Recieved free with a purchase, but will be 100% buying some! Taste is awesome!
  2. Wow


    The guys at Grenade have done it again with this incredible shake. I tend to treat myself to one of these after a heavy leg day and can absolutely feel the benefits. No idea how they manage to make then taste so good while keeping the sugars to a minimum. I've tried both the Fudge Brownie and Chocolate Mint. Fudge Browine was definitely my preferred of the two and tasted just like a creamy chocolate milkshake, yum! Will be ordering the Cookies and Cream with my next order
  3. How!


    I have tried countless protein shakes over the years, i have no idea how they have left out all the bad stuff and made them taste so good ? These are a must have and the Fudge Brownie shake is incredible!
