Vitamin K1 (Phytonadione) is a prescription medication used as a supplement in people with vitamin K deficiency. Vitamin K is an essential vitamin the body needs for important processes like blood clotting and bone building. Low levels of blood clotting factors increase the risk of unusual bleeding. Vitamin K occurs naturally in leafy green vegetables and broccoli. The active ingredient in Vitamin K1 is Phytonadione. Phytonadione belongs to a class of drugs called vitamins. It works by providing the body with vitamin K needed for blood clotting. Phytonadione is a man-made (synthetic) form of vitamin K.
We currently offer the brand Vitamin K1 from Canada manufactured by Baxter Healthcare in the strength of 10mg/ml ampules injection. The generic Phytonadione is not available.
