The Claim

Intermittent zinc supplementation in infants is associated with a 79% reduction in mild acute respiratory infections and a 63% reduction in moderate to severe diarrhoea.

In plain English

Infants who receive intermittent zinc supplements have 79% fewer mild respiratory infections and 63% fewer moderate to severe diarrhoea cases compared to those who do not.

See the scientific wording

Intermittent zinc supplementation in infants is associated with a 79% reduction in mild acute respiratory infections and a 63% reduction in moderate to severe diarrhoea, suggesting differential protective effects by disease severity.

Why this might work

Zinc strengthens the lining of the gut and lungs, stops viruses from multiplying inside cells, and helps immune cells clear infections faster, which cuts down on both stomach bugs and colds in babies.

What the research says

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

    The study shows zinc supplements help babies get fewer colds and stomach bugs, but it doesn't say whether they work better for mild vs. severe cases, so we can't confirm the claim about different levels of protection.
