Vitamin k
Typically they'll do your bloodwork to see what you are deficient in before surgery. Official want to get your levels somewhat normal before surgery. So not every one would be deficient in it or required to take it

The only centre that does this for all patients is Hamilton, otherwise it just depends on the practise of the surgeon. The reason it is prescribed is because optifast does not have Vitamin K in it. Given the importance of Vitamin K in blood clotting, I guess there is a concern about developing a deficiency right before surgery. From what I've read though it would take at least several weeks, months even, of a diet completely lacking in Vitamin K to cause problems. I'm sure the docs who don't prescribe it are not taking any chances, it's probably more that the surgeons that do it have had a problem at some point in the past, or are just super, extra prudent. If you're concerned though, look at your multivit and check to see if it has K in it, that's another way to get it.
