Special K is an American brand of breakfast cereal and meal bars originally manufactured by Kellogg's. The cereal was introduced to the United States in 1955. It is made primarily from grains such as lightly toasted rice, wheat and barley. Special K used to be marketed primarily as a low-fat cereal that can be eaten to help one lose weight. Following the 2023 spinoff of Kellogg's North American cereal division, the cereal is manufactured by WK Kellogg Co for the United States, Canada, and Caribbean markets. The former Kellogg's, renamed Kellanova, continues to manufacture the cereal for the rest of the world and the meal bars for all markets.
