Vitamin D3 to help recovery after mild-to-moderate traumatic brain injury

Official title: Vitamin D3 for Moderate to Mild Traumatic Brain Injury: A Randomized Trial on Inflammation and Recovery (VIMOT)

Run by Lagos State University · NCT07269457 · Data updated 2026-11-12

This trial will test whether a short course of vitamin D3 helps adults (18–65) recover better and reduce inflammation after mild-to-moderate traumatic brain injury.

Is this trial a fit for you?

Likely a good fit

Adults aged 18–65 presenting within 24 hours of a mild-to-moderate TBI (GCS 9–15) who can consent and do not have contraindications such as recent vitamin D use, hypercalcemia, severe liver or kidney disease, or pregnancy are ideal candidates.

Probably not a fit

People with severe TBI (GCS ≤8), recent vitamin D supplementation, pregnancy or lactation, hypercalcemia/hyperparathyroidism, end-stage renal disease, chronic liver disease, or those on immunosuppressive drugs are unlikely to be eligible or to receive benefit from this protocol.

What this trial studies

This Phase II, randomized, quadruple-blinded, placebo-controlled trial will enroll 240 adults with mild-to-moderate TBI at Lagos State University Teaching Hospital. Participants will be stratified by baseline vitamin D status and randomized into four arms receiving either a high-dose loading plus daily cholecalciferol, standard-dose cholecalciferol, or placebo for three weeks. Outcomes include blood markers of inflammation and functional recovery measures such as the Glasgow Outcome Scale–Extended and the modified Rankin Scale, with safety monitoring and follow-up to 24 weeks. The design tests both correction of deficiency and dose effects in a low- and middle-income country setting.

Why it matters

Potential benefit: If successful, this could offer an inexpensive, widely available way to reduce brain inflammation and improve functional recovery after TBI.

How similar studies have gone: Preclinical and observational data suggest vitamin D has anti-inflammatory and neuroprotective effects, but randomized trials of vitamin D for TBI—particularly in LMIC settings—are limited or absent.
