Thank you for your kind words. It sounds like you have been doing your homework! Vitamin K has made headlines recently for a possible link to the novel virus, COVID-19. There are two main types of this vitamin: K1 and K2. K1 is the main dietary source and is found naturally in dark green, leafy vegetables, such as spinach, kale, green leaf lettuce and broccoli. K2 is primarily bacterial in origin and is produced in the human intestines. It is also found in modest amounts in fermented foods like sauerkraut and natto, a soy dish. Meat, cheese, and beef liver are animal sources of K2.
