Daily vitamin d may slash lung risks in kids with sickle cell disease

NCT ID NCT04170348

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This study tested whether taking vitamin D every day could reduce lung complications in children and teens with sickle cell disease. Lung problems like infections, asthma attacks, and acute chest syndrome are major causes of illness and death in this condition. Researchers gave daily or monthly vitamin D3 or a placebo to 58 participants aged 3-20 to see if it lowered the rate of these respiratory events.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Vitamin D3 (cholecalciferol)

What this could lead to

If it works, daily vitamin D could become a simple, low-cost way to cut the risk of serious lung problems in children with sickle cell disease.

What could go wrong

This is a small Phase 2 trial with only 58 participants, so results may not apply to everyone. Vitamin D is generally safe, but high doses can cause side effects like high calcium levels.
