The Claim
Intermittent zinc supplementation in infants reduces the incidence of moderate-to-severe diarrhoea by 63% and acute respiratory infections by 72%, with efficacy varying according to disease severity, indicating a biological mechanism involving immunomodulation or mucosal repair.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Giving zinc supplements to infants at intervals reduces moderate-to-severe diarrhoea by 63% and acute respiratory infections by 72%, with greater effects in more severe cases, due to biological effects on immune function or mucosal tissue repair.
See the scientific wording
Intermittent zinc supplementation in infants reduces moderate-to-severe diarrhoea by 63% and acute respiratory infections by 72%, with differential efficacy by disease severity, suggesting a targeted immunomodulatory or mucosal repair mechanism.
Zinc turns on enzymes that build DNA, repair tissues, and fight viruses by controlling gene activity and blocking viral replication.
What the research says
2 studiesGiving babies zinc supplements a few times helped them get sick less often with diarrhea and colds, and they also grew better. This suggests zinc helps their bodies fight off infections.
Study: Comparative study of different doses of oral zinc supplementation in children with acute diarrhea
Giving zinc to sick babies helped them get over diarrhea faster, especially with higher doses, and it works by healing the gut and boosting immunity. But this study didn’t check if zinc helps with colds or breathing problems.
