This paper is a meta-analysis of studies looking solely at iron stores among vegetarians vs omnivores. It doesn’t broadly address the claim about nutritional deficiencies among those who consume a meat-free diet more broadly. Moreover, among the studies they examined there was significant variability among cutoffs for serum ferritin as indicative of storage iron. About all I can conclude is that premenopausal vegetarian women should supplement with iron.
