Randomized Controlled Trial Assessing Vitamin D’s Role in Reducing BPPV Recurrence in Older Adults

To determine if the recurrence rates of BPPV in older adults were lower in the vitamin D‐treated group as compared to placebo groups.

Double‐blinded randomized control placebo trial.

A single‐centre study.

Double‐blinded randomized controlled trial design with 12 months follow‐up. Vitamin D3 deplete participants were randomized into treatment (Group A) or placebo groups (Group B). Treatment group received 13 weeks of 2000 IU vitamin D3 followed by 1000 IU for the next 13 weeks. Patients who were replete were allocated to a control group (Group C) for observation and follow up. All groups had dietary interventions for vitamin D3 and calcium.

Results showed an 87% reduction in recurrence rates of BPPV in the treatment group (Group A), with 0.75 fewer clinical episodes per 1 person‐year as compared to placebo (Group B). Time to first recurrence …
