Vitamins for balls in not necessary. In a serous case of neglect...maybe. They get ALL their nutrients form their pray items. If she wasn't eating and/or had mites THEN I would suggest a trip to a good reptile vet for a de-worming and treat the cage with Prevent-o-Mite. But if she is eating, has good stool (not runny or strangely smelly or colored), no mites, and is alert and active she is probably just fine.
