                                Benign paroxysmal positional vertigo (BPPV) has a one-year recurrence rate of about 20%, a common issue that significantly impacts quality of life. While not the cause of every case, a growing body of evidence strongly links vitamin D deficiency and suboptimal calcium metabolism to the occurrence and, more notably, the recurrence of BPPV episodes.
