Phylloquinone - Feed Ingredient

Phylloquinone, also known as vitamin K₁, is a fat-soluble vitamin primarily involved in blood clotting through its role in synthesizing clotting factors in the liver. It is the natural form of vitamin K found in green leafy plants and is the primary dietary source of vitamin K for herbivores.

In equine nutrition, phylloquinone is typically obtained through forage consumption, particularly fresh pasture and hay. Horses on diets with adequate forage generally meet their vitamin K needs without supplementation. However, phylloquinone may be added to feed or supplements in situations where forage intake is limited or during intensive care.
