Toward Supplementation Guidelines for Vegan Complementary Feeding.

Previously published recommendations for vegetarian (including vegan) diets for children have highlighted the need for vitamin B12 supplementation. Increased attention to several other key nutrients (including iodine, vitamin D, calcium, and iron) has also been recommended. However, an overview focusing on supplementation guidelines, specifically for vegan infants, has not been published, and a potential requirement for iodine and/or selenium supplementation in (some) vegan infants has not been discussed. Vegan complementary feeding should be supplemented (particularly with 5 μg/day of vitamin B12 and 10 μg/day of vitamin D). Iodine should be supplemented (up to 110 μg/day) if the intake of breast milk and infant formula is low, and selenium supplementation (5 μg/day) should be considered in regions with low soil selenium levels. Caution is required to avoid excessive intakes of iodine and particularly selenium. Supplements for vegan infants are on the market, and observational studies are urgently needed to assess the nutrient intake (including supplements) and status in vegan infants.
