Does vitamin d affect ALS? researchers check blood levels
NCT ID NCT01823380
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at whether vitamin D levels in the blood are linked to how fast ALS (Lou Gehrig's disease) gets worse. Researchers measured vitamin D in 127 people with ALS and tracked their motor decline, breathing, and weight loss. No treatment was given—the goal was simply to see if a connection exists.
