What is Vit K made of?

[Lucy]

Lisa, I have found the info given to me by my OB.

It is a type-written document on his practices notepaper, which is stapled to a pamphlet outlining "Vitamin K for Newborn Babies, Information for parents" which is issued by the Australian Government (National Health & Medical research Council). The pamphlet itself doesn't contain any specific info regarding cow bile, hence, I think, he has attached his own info.

The pertinent detail of his own typewritten info says:

In both the oral and intramuscular paediatric formulations, the "Vitamin K" formulation contains phytomenadione (Vitamin K) as well as sodium glycocholate (cow bile) and lecithin (both naturally occurring substances). The combination of the sodium glycocholate (cow bile) and the lecithin mean that the phytomenadione (Vitamin K) becomes soluble in a liquid medium.

There are no references on his type-written document, so I am unsure as to where he would have sourced this info, aside from his own learning/awareness/the drug manufacturer. It seems to me that it is written in fairly easy "lay-mans" terms.

(It made sense to me when I read it at any rate. I understood it was cows bile, and I understood the bile component was deemed necessary, as I already knew Vit K was a fat soluble vitamin substance. So I understood that if I chose to have the Vit K administered for my babies, it would have to be in this "mixture".)
