Cause and effect
1 study reviewed
In plain English

Giving children under 5 years old zinc supplements for 14 days at doses between 20 and 60 mg per day reduces the length of acute diarrhea, with the highest dose providing the greatest reduction.

See the scientific wording

Oral zinc supplementation at any dose (20–60 mg/day) for 14 days significantly reduces the duration of acute diarrhea in children under 5 compared to no supplementation, with the greatest benefit observed at 60 mg/day.

Why this might work

Zinc enters the body through the gut, strengthens the lining of the intestines, turns back on enzymes that absorb nutrients, blocks channels that pump water into the gut, and helps the immune system kill germs causing diarrhea. Together, these actions stop the gut from leaking fluid and clear the infection faster.

    Giving kids with diarrhea zinc pills for two weeks helps them get better faster than not giving them anything, and the higher the dose (up to 60 mg), the quicker they recover.
