The Claim
Oral supplementation of 10 mg zinc daily increases serum zinc levels in preterm infants born between 28 and 32 weeks gestation from baseline to 40 weeks post-menstrual age, resulting in levels higher than those in placebo-treated infants.
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 who receive 10 mg of oral zinc daily show higher blood zinc levels at 40 weeks post-menstrual age compared to infants who receive a placebo.
See the scientific wording
Serum zinc levels in preterm infants born between 28 and 32 weeks gestation increase significantly from baseline to 40 weeks post-menstrual age when supplemented with 10 mg of oral zinc daily, reaching levels above those in placebo-treated infants, suggesting that enteral zinc replacement can correct deficiency in this population.
When a preterm infant takes a zinc pill, the zinc passes through the gut and enters the bloodstream through special transporters. Once in the blood, the zinc raises the total amount of zinc circulating in the body, which is measured as higher serum zinc levels compared to infants who do not take the pill.
What the research says
1 studyStudy: Zinc supplementation in preterm infants and growth indicators in a developing country
Babies born early who got a daily zinc pill had much higher zinc levels in their blood by the time they were due to be born, compared to babies who got a fake pill. This shows zinc pills can fix low zinc levels in premature babies.
