As you can see from the above, vitamin D is cheap so they throw in 120% of the supposed daily requirement in an 8 oz bottle (350 calories out of a supposed 2000 calorie diet).

However, vitamin K obviously is an expensive vitamin. You only get 25% of your daily requirement.

According to Dr. Mercola's (from his website) Story at-a-glance: "Evidence shows that vitamin D is dependent on vitamin K, and that vitamin D toxicity is actually caused by vitamin K2 deficiency."
