My whole family is vegetarian, my 2 y/o has never had any type of meat. We all take a good muti everyday and we are all doing great. My 2 y/o just had her iron levels taken and they were perfect, and that was before she started taking the vitamins.
I know tons of vegetarians and vegans and I don't personally know a single person who's had any health problems. And ITA with the pp who said they would take a multi whether veg or not
