does anyone know where vitamin K is absorbed?

I think small intestine. The large intestine has some bacteria that make vitamin K too, but it is not much.

You think at duodenum?

Ileum + jeujenum (spelling?) is my guess. But not sure at all.

Only thing I could find http://forums.studentdoctor.net/showthread.php?t=608349

Since Vit. K is one of the fat sol vitamins it gets abs along with fats in the small intestine. Checked my nutrition book.

Question is, which part of the small intestine?

the small part of the small intestine

To be super specific...... dietary vit. k is provided mostly as phylloquinone in plant food and a mixture of menaquinone in animal products...... phylloquinone (vit k) is absorbed from the small intestine, particularly from the jejunum. 🙂

what if you were born without small intestines or had your jejunum removed, what then?
