The Claim
Prophylactic zinc supplementation at 20 mg/day for two weeks in infants aged 6 to 14 months is associated with a 14% reduction in the total number of days with acute respiratory infections and no significant reduction in the number of infection episodes.
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.
In infants aged 6 to 14 months, taking 20 mg of zinc daily for two weeks is linked to 14% fewer total days of acute respiratory infections, but does not change how often infections occur.
See the scientific wording
Prophylactic zinc supplementation at 20 mg/day for two weeks in infants aged 6 to 14 months is associated with a 14% reduction in the total number of days with acute respiratory infections, but does not significantly reduce the number of infection episodes, suggesting a potential benefit in shortening illness duration rather than preventing infection onset.
Zinc enters the bloodstream and strengthens the lining of the airways, making it harder for viruses to damage cells. It also turns up the activity of white blood cells that clean up infected tissue, allowing the body to clear the infection faster and reduce how long symptoms last.
What the research says
1 studyGiving babies zinc every day for two weeks didn’t stop them from getting sick as often, but it did help them feel better faster — they were sick for fewer days overall.
