I don't normally go for vitamin supplements, I eat a fairly healthy diet and am basically a stingy cynic. 
But I'm on my second bout of gastroenteritis in ten days and am probably also a little run down; although I'm aware bump will take all the nutrition before me, I'm starting to get a little concerned for it.
Opinions - is Pregnacare and the like worth it, or should I just buy decent OJ and a bag of salad etc.
TIA
