... Abstract Vitamin B12 is a fascinating nutrient in that it is made by microbes but is essential for human metabolism. Humans can get it only from animal origin foods. Dietary deficiency rather than an absorption defect (Pernicious anemia, intrinsic factor defect) is the commonest cause...

... that children following plant-based diets have adequate amounts of key nutrients, such as energy, fats, iron, calcium, iodine, vitamin B12, and omega-3 fats. In the VeChi studies, vegan children had the lowest intakes of calcium and iodine out of the three diet groups. The vegan children also had the lowest...

..., and particularly vitamin B12. Deficiencies in these nutrients can lead to severe and sometimes irreversible developmental disorders. If such a diet is chosen for ethical, ecological, or health reasons, a well-planned, diversified diet with additional supplementation of vitamin B12, vitamin D, iodine...

... vegetarianism are due to scientific data from studies without this differentiation.In the past, vegetarian diets have been described as being deficient in several nutrientsincluding protein, iron, zinc, calcium, vitamin B12 and A, n-3 fatty acids and iodine.

Therapeutic trial...
