Should you supplement with vitamin K?
Vitamin K is poorly understood, both by the general public and among health professionals. It has a wide range of potential benefits, but their nature and extent are still uncertain.
Why is that?
Some vitamins are more popular than others. In the past, a lot of research went into vitamin C, which became a popular supplement. Nowadays, a lot of research goes into vitamin D, whose popularity as a supplement is steadily growing.
By contrast, research on vitamin K is still scarce, having slowly developed over the past two decades. Further, it is scattered, because there exist several forms of vitamin K. Some of those forms are present only in a few foods. Others exist in various foods, but only in minute amounts. Few have been the subject of human trials.
