Could extra vitamin d help tiny preemies breathe easier?

This study looks at whether giving a higher dose of vitamin D (800 IU per day) to extremely premature infants (born before 28 weeks or weighing less than 1000 grams) improves their health compared to the usual dose. Researchers will check vitamin D levels and measure effects on the lungs, bones, immune system, and brain. The goal is to see if this simple supplement can reduce breathing problems and other complications in these fragile newborns.
