King Vitaman was an American brand of breakfast cereal produced by Quaker Oats and sold in the United States.

[1] King Vitaman Cereal boasted high vitamin and iron content, in addition to a more modest amount of sugar (6 grams per serving) than many more popular breakfast cereals, such as Cap'n Crunch and Lucky Charms (which contain 13 grams or more).

The early television commercials for the cereal were animated by Jay Ward Productions, the creators of Rocky and Bullwinkle.

Subsequent non-animated advertisements ended with a jingle inviting children to "Have Breakfast with the King."

[2] In 2000, Quaker Oats returned to an illustrated character on their King Vitaman cereal boxes.
