Vitamin B12, Vitamin D, and Vitamin K are all vitamins that the liver stores. If you were to take too much of Vitamin B12, it would be filtered through your liver (whole holding onto some), then through your kidneys to be urinated out.
Vitamin D and K
I don't believe there is such a thing as vitamin k, but they are high in antioxidants.
These are the FAT soluble vitamins (vitamin A, vitamin D, vitamin E and vitamin K). Lipase from the pancreas is required to help a person absorb these vitamins.
