Heavier children and teens are at a greater risk for low vitamin B12 levels, report Israeli researchers who studied 392 young people. While 10.4% of obese subjects were found to have low B12, only 2.2% of normal weight subjects were low. The results suggest that obesity in children and adolescents may be a risk factor for vitamin B12 deficiency.
