The Claim
Oral zinc supplementation at 10 mg per day for up to 40 weeks post-menstrual age increases serum zinc levels and improves weight gain velocity in preterm infants born between 28 and 32 weeks gestation without causing observable side effects.
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.
Preterm infants born between 28 and 32 weeks gestation who receive 10 mg of oral zinc daily for up to 40 weeks after their due date have higher serum zinc levels and faster weight gain compared to those who do not, with no observable side effects.
See the scientific wording
Oral zinc supplementation at 10 mg per day for up to 40 weeks post-menstrual age significantly increases serum zinc levels and improves weight gain velocity in preterm infants born between 28 and 32 weeks gestation, without causing observable side effects, suggesting targeted zinc replacement may support nutritional recovery in this vulnerable population.
Zinc from supplements enters the bloodstream and activates molecules that turn on genes for cell growth and protein production. This causes cells in muscles, fat, and other tissues to divide faster and make more protein, leading to faster weight gain.
What the research says
1 studyStudy: Zinc supplementation in preterm infants and growth indicators in a developing country
Giving preterm babies a daily zinc pill helped their blood zinc levels go up and made them gain weight faster than babies who got a fake pill — and no side effects were seen.
