Doctors test High-Dose vitamin d for sick Kids' bones and health

This study checked if a standard high-dose vitamin D treatment was effective and safe for children and teens with chronic kidney disease, a transplant, or a kidney syndrome. Researchers gave 43 participants a single large dose of vitamin D and measured their vitamin D levels two months later to see if they reached a healthy target. They also carefully tracked calcium in the children's urine to make sure the large dose did not cause any harmful side effects.
