Vitamin D3-enhanced Eggs in Preschool Children

"In our study, the vitamin D3-enhanced eggs were produced by hens that received 23,500 IU of vitamin D3 per kg of feed. Which does not confer them any harm or danger of intoxication. This experiment was carried out at the Center for Teaching, Research and Extension in Poultry Production (CEIEPAv, FMVZ-UNAM) and lasted 40 weeks.~This ensured that the hens eggs were enhanced with vitamin D achieving a final concentration of approximately 400 IU of vitamin D"

Unfortified eggs were used for the control group with a concentration of approximately 43 IU of vitamin D
