colivarez1, I noticed these were answered in a previous thread. Do you still need assistance with them? Do a search in case you cannot find them.

This vitamin is absorbed by the stomach. If the person has cancer in his stomach, the mechanism responsible for absorbing the vitamin may not work efficiently or even at all. Why can’t the vitamin be delivered in tablet form? Well, there's no point because of the aforementioned reason. If it's not going to be absorbed by the stomach, it's not going to be absorbed by the intestines.
