If the Nutrition Facts say "Iron 50%", this means that consuming the food inside this package provides the consumer with 50% (or half) of the Daily Value of Iron that they need to consume per day.
The nutrition facts label on a food package lists "iron 50%".  this figure indicates that
 the if a person will take this package he will get benefit from this and will get 50% of iron energy from this meal
hope it helps
