Following the launch of its Carb Killa shakes, bars, spreads and brownies, Grenade is expanding its protein product portfolio with the introduction of a new biscuit snack.

Available on now and rolling out to independent stores next year, the new Carb Killa Biscuit is coated in chocolate and filled with crispy pieces.

Available as a two pack, in either Double Chocolate or Salted Caramel flavours, each biscuit contains 109 calories, 6g of protein and 0.8g of sugar (rrp £2.50).

Juliet Barratt, co-founder and cmo of Grenade, said: “We are so excited to be launching the Carb Killa Biscuit. We’re hoping that this new addition will excite current Grenade fans and reach out to an ever-growing demographic of customers looking for something healthy and nutritious but different.”
