Question about fat soluble vitamins

[IronFist]

Ok, take a fat-soluble vitamin like vitamin A. If you were to injest some by itself, on an empty stomach, and there was no fat with which to metabolize it, what would happen to it?

I wouldn't think it would get stored, cuz there's no fat there with it. It wouldn't be used for the same reason. And I don't think you would just pee it out because it's not water-soluble.

Fat is absorped in the small intestine. So the vitamin has to pass though the stomach. In fact most things are absorped in the small intestine.

When you eat a meal with fat or oil in it, it stimulates your gall bladder to dump some bile into the gut. This acts like detergent to break up the fats, including your vitamin A supplement. If the fat soluble vitamins don't get dispersed, then some might not get absorbed and would travel all the way though your digestive tract and exit in the same form it entered (minus the capsule). Some of it would get absorbed anyway, just because fats will go through the lining of the gut.

Most of the vitamen A would exit through the feces although a small amount would get through the intestinal lining. You would'nt pee any out since it's not water soluble.
