Benign paroxysmal positional vertigo (BPPV) is a common peripheral vestibular disorder in which early nonresponse and recurrence remain clinically important. Vitamin D has been hypothesized to influence otoconial stability and inner-ear mineral homeostasis and may be associated with BPPV prognosis....
Low vitamin D may be associated with worse BPPV prognosis and higher recurrence; audiologists and ENT clinicians managing BPPV patients could consider flagging low vitamin D for physician follow-up, though this study alone is insufficient to change standard repositioning treatment protocols.
If confirmed in prospective trials, vitamin D supplementation could become a simple, low-cost adjunct to reduce BPPV recurrence — a meaningful quality-of-life improvement for a very common vestibular condition.
- 01Study published in Frontiers in Nutrition examined serum 25-hydroxyvitamin D levels in BPPV patients.
- 02Lower vitamin D levels were associated with poorer treatment outcomes and higher recurrence rates.
- 03BPPV is the most common cause of positional vertigo, making this finding broadly clinically relevant.
- 04Observational/prognostic design; causality and optimal supplementation thresholds not yet established.
- 05Supports growing body of literature linking vitamin D deficiency to vestibular dysfunction.
Lower serum 25-hydroxyvitamin D levels are associated with worse prognosis and higher recurrence rates in BPPV.
