Kellogg has renovated its Special K cereal bar portfolio on sale in the US to include more fibre.

The company said that its Special K Blueberry, Chocolatey Drizzle, Chocolatey Pretzel, Honey Nut, Peaches and Berries, Strawberry and Vanilla Crisp bars would now include three grams of fibre.

Kellogg has also launched two more Special K bars - Chocolatey Chip Cookie and Raspberry Cheesecake.

"Special K continues to provide a simple solution to help consumers jump-start their realistic, attainable weight management goals with great-tasting foods."
