- [[Vitamin K]]
- [[B vitamins|B1 (thiamin)]]

Two more B vitamins (biotin and panthothenic acid), and two unusual compounds (choline and carnitine) are also valuable

Vitamins are classified as **water soluble** or **fat soluble**
If you consume larger amounts of fat-soluble vitamins, the excess is stored in body fat
If you consume larger amounts of water-soluble vitamins, the excess is urinated

>[!History of vitamins]
> By the end of the 18th century, British Navy ships carried a mandatory supply of limes or lime juice to prevent scurvy, thus earning the British the nickname "limeys"
> No one really knew why it helped until Casimir Funk identified something in food that he called "vitamines" (vita = life, amines = nitrogen compounds)

For example, vitamin E keeps vitamin A from being destroyed in your intestines, and sometimes one vitamin may even alleviate a deficiency caused by the lack of another vitamin.
