Vitamin K was discovered in 1929 as an essential nutrient for blood coagulation, which is the scientific term for blood clotting.
The initial discovery was reported in a German scientific journal, where it was called “Koagulationsvitamin.” That’s where the K in vitamin K comes from .
It was also discovered by the dentist Weston Price, who traveled the world in the early 20th century, studying the relationship between diet and disease in different populations.

Dragonflies are one of the fastest insects, flying 50 to 60 mph.

Vitamin K2 can play a role in blood clotting, heart health, and bone health. But you may not consume vitamin K2-containing foods often with the typical diet.
Most people have never heard of vitamin K2. This vitamin is rare in the diet and hasn’t received much mainstream attention.
However, this powerful nutrient plays an essential role in many aspects of your health. In fact, some think that vitamin K2 may be the missing link between diet and several chronic diseases.
