The Claim

Intermittent zinc supplementation in zinc-deficient infants reduces acute respiratory infections by 72% and acute diarrhoea by 49% while significantly increasing weight gain and linear growth over six months.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

Giving zinc supplements to zinc-deficient babies every few weeks cuts their chances of getting respiratory infections and diarrhea by more than half and helps them grow bigger and taller.

See the scientific wording

Intermittent zinc supplementation in zinc-deficient infants reduces acute respiratory infections by 72% and acute diarrhoea by 49% while significantly increasing weight gain and linear growth over six months.

Why this might work

Zinc boosts growth by activating enzymes and hormones that build muscle and bone, while dietary protein provides the amino acids needed to fuel this process.

2 studies

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

    Giving babies zinc supplements a few times over six months helped them get fewer colds and stomach bugs, and they also grew taller and heavier than babies who didn’t get the supplements.

  2. Study: Impact of zinc supplementation on diarrheal morbidity and growth pattern of low birth weight infants in kolkata, India: a randomized, double-blind, placebo-controlled, community-based study.

    This study gave babies a daily zinc supplement and found they got fewer diarrhea bugs and grew better than babies who didn’t get zinc. While it didn’t test the exact same schedule or measure respiratory infections, it still shows zinc helps sickly babies stay healthier and grow stronger.
