Summary

This study looks at whether giving extra vitamin D (800 IU daily) to extremely premature infants (born before 28 weeks or weighing under 1000 grams) improves their lung, bone, immune, and brain health. About 180 babies will receive either the extra vitamin D or usual care for the first 28 days after birth. The goal is to see if this simple supplement can help these fragile infants grow stronger.
