Hi Granbonny-
When Joe was last in the hospital, he had lost a lot of weight. One day, magically, a container of Enliven! appeared on his food tray. That's a fruit flavored nutritional supplement.
I looked at the ingredients, and there was Vitamin K, each container had 25% of the normal daily amount. It arrived with each food tray. I nearly blew a gasket. When I complained about it to the nurse, the next day, a can of Boost arrived with each meal. The ingredients had Vitamin K, 40 % of the normal daily amount in each can. That arrived with each meal. That gave me the opportunity to have a little chit-chat with the hospital dietician, a very young assertive gal. She was totally clueless as to what the Vitamin K would do to my husband. Hard to believe. I told her that I wouldn't dream of giving him a Vitamin K pill.
I guess, she had never met a rather older assertive gal.
I won. Joe never drank any of that. I brought some Ovaltine and Nestle Quick from home.
So, ya just never know. And neither do a lot of other people who should know.
