Vitamin K1 vs K2
There are two primary forms of vitamin K: vitamin K1 (phylloquinone) and vitamin K2 (menaquinone).
Vitamin K1 (Phylloquinone): Also known as phylloquinone, vitamin K1 is the natural form of vitamin K found in plants. It is primarily found in green leafy vegetables such as spinach, kale, broccoli, and parsley. Vitamin K1 is the predominant form of vitamin K in the human diet.
Vitamin K2 (Menaquinone): Vitamin K2 refers to a group of compounds known as menaquinones. It is produced by bacteria in the intestines and is also present in certain animal products and fermented foods. Vitamin K2 is further classified into several subtypes, including menaquinone-4 (MK-4) and menaquinone-7 (MK-7). MK-4 is found in animal products such as meat, eggs, and cheese, while MK-7 is commonly found in fermented foods like natto (fermented soybeans). Other sources of vitamin K2 include liver, butter, and some types of cheese.
