Scientific research found that researchers from the Hopkins School of Public Health in Baltimore and the Institute of Medical Sciences in New Delhi, India, evaluated the effect of zinc supplementation on 298 children aged 6 months to 3 years, and compared them with the same number of children who did not receive zinc supplementation. Infants supplemented with zinc should be supplemented with 10 mg of zinc every day for half a year.
