In plain English

Infants who receive intermittent zinc supplements along with their routine vaccines experience 4.54 fewer days of diarrhoea per year compared to infants who receive only vaccines.

See the scientific wording

Intermittent zinc supplementation administered alongside routine vaccinations reduces the cumulative duration of diarrhoea by 4.54 days per child-year in infants, indicating a meaningful reduction in illness burden beyond incidence.

Why this might work

Zinc helps repair the lining of the gut, stops too much fluid from leaking into the intestines, and improves digestion so stool becomes less watery and less frequent, which cuts down the total number of sick days from diarrhoea.

  1. Study: Efficacy of prophylactic intermittent zinc supplementation for reducing acute respiratory infections and diarrhoea in infants: A randomized controlled trial

    Zinc supplements helped babies get diarrhoea less often, which probably means they felt sick for fewer days overall — but the study didn’t measure exactly how many days each sickness lasted.
