So, even though blood values are similar in vegetarians and omnivores, stores aren't. It seems that vegetarians generally absorb enough iron to maintain good health, but not enough to build up stores. I really don't know whether this is a problem or a benefit. But the difference in stores is pretty big. The average male omnivore stores about 1,000 mg of iron and the average female omnivore stores about 300 mg.
Male vegetarians have stores that are comparable to female omnivores.
