Why is vitamin K a key nutrient?
There are two naturally occurring forms of this powerful nutrient (vitamin K1, which is found in plants, and vitamin K2, which is produced from vitamin K1 by bacteria in the digestive tract). Vitamin K3 is a synthetic form of the nutrient, found only in supplements. Recent research suggests that people who suffer from cancer, bruising, heart disease, menstrual problems, hemorrhagic disease or kidney stones may especially benefit from getting their daily dose of the nutrient.
