Special K® cereal and Warfarin
By: Alere Staff
Special K® cereal products might make you wonder if this healthy product brought to you by the Kellogg's company is a secret source of vitamin K. PTINR.com called the Kellogg's company to inquire whether their Special K® cereal products is fortified with vitamin K. Kellogg's does not fortify their cereal with vitamin K.
The nutritional facts do not suggest there is any vitamin K in Special K® since it is not listed. Vitamin K is not required by the U.S. Food and Drug Administration (FDA) for product labeling.
A main ingredient in Special K® cereal is whole grain wheat which, according to the United States Department of Agriculture is high in vitamin K. The important question that needs to be asked is whether the whole grain wheat is in a concentration large enough to influence an INR test result for a patient that consumes Special K® cereal daily.
Eating pure whole wheat flour by itself would represent 251 micrograms per 3.5 ounces per serving. A bowl of Special K® cereal would not contain 3.5 ounces of wheat flour. PTINR.com has requested an evaluation of Special K® cereal to determine how many micrograms are in a bowl of cereal. An average serving of Special K has 0.2 micrograms.
