A new clinical report demonstrates that adequate vitamin D supplementation markedly increases the long-term efficacy of the Epley maneuver, reducing vertigo attacks after initial maneuvers. The researchers concluded, “The results of this study demonstrated a significant decrease in the intensity of BPPV two months after treatment in all groups irrespective to serum 25-OHD status. Thereafter, improvement persisted in vitamin D sufficient and vitamin D treated groups but regressed to baseline value in vitamin D deficient group.” They added, “Based on the results of this study, Epley’s therapy is effective in the treatment of BPPV for a short time period but persistent of improvement requires normalization of serum vitamin D in those who have vitamin D deficiency.” The amount of vitamin D required for this good result was not specifically stated, but 5000 IU of vitamin D-3 daily tends to be required for adequate health benefits.
