The Claim
Intermittent zinc supplementation in infants is associated with a large effect size (Cohen’s d = 3.56) for weight gain and 2.74 for length gain, indicating a substantial biological impact on growth that exceeds typical nutritional interventions.
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.
Infants given intermittent zinc supplements show significantly greater increases in weight and length compared to those not receiving such supplements, with effect sizes larger than those seen in most other nutritional interventions.

Intermittent zinc supplementation in infants is associated with a large effect size (Cohen’s d = 3.56) for weight gain and 2.74 for length gain, suggesting a substantial biological impact on growth that exceeds typical nutritional interventions.
Zinc activates enzymes that build proteins and copy DNA, allowing cells to multiply and tissues to grow faster. It also helps the body produce and use a key growth hormone, which tells bones and muscles to get bigger. When zinc is available, babies gain weight and length more quickly because their bodies can make more cells and tissue.
What the research says
1 studyThis study found that giving babies zinc supplements every few months helped them grow much faster in weight and height than babies who didn’t get zinc — so much faster that it’s way bigger than most other baby nutrition fixes.
