Vitamin K1

Vitamin K1, also known as phylloquinone, is a fat-soluble vitamin naturally found in leafy green vegetables like spinach, kale, and broccoli. It plays a crucial role in blood clotting and bone health. In food production, it can be extracted from plant sources.

Vitamin K1 is primarily added to foods as a nutrient to fortify them, helping consumers meet their daily intake recommendations. It is commonly found in fortified breakfast cereals, drinks, and infant formulas. Manufacturers add it to enhance the nutritional profile of their products.

The U.S. Food and Drug Administration (FDA) recognizes Vitamin K1 as a dietary ingredient. It is essential for normal blood coagulation. While generally safe when consumed in amounts found in food, high doses can interfere with anticoagulant medications. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have evaluated vitamin K, but specific numeric intake limits are not typically set for this nutrient in the context of food additives.
