Vitamin K1, also known as phytomenadione, chloromenadione, chloroquinone, chemically known as 2-methyl-3-phytyl-1, 4-naphthoquinone, is a polycyclic aromatic ketone, a fat-soluble vitamin that is stable to air and humidity, but is broken down in sunlight. It is widely found in natural green plants.
Vitamin K1 powder comes in three forms: phylloquinone, menaquinone, and menadione. Phylloquinone, or K1, is found in green leafy vegetables, and helps bones absorb and store calcium. One recent study showed that increased amounts of vitamin K in the diet might lower the risk of hip fracture; over time, a shortage of vitamin K could lead to osteoporosis. Menaquinone, or K2, is manufactured in the body by naturally occurring intestinal bacteria. People that regularly take antibiotics or have a medical condition that upsets the balance of bacteria in the intestine are at risk of developing a vitamin K deficiency. Menadione, or vitamin K3, is an artificial form of vitamin K, which is water soluble and more easily absorbed by people who have problems with fat absorption.
