Taking vitamin D and calcium twice a day may reduce your chances of getting vertigo again, according to a study published in the August 5, 2020, online issue of Neurology, the medical journal of the American Academy of Neurology.

"Our study suggests that for people with benign paroxysmal positional vertigo, taking a supplement of vitamin D and calcium is a simple, low-risk way to prevent vertigo from recurring," said Ji-Soo Kim, M.D., Ph.D., of Seoul National University College of Medicine in Korea. "It is especially effective if you have low vitamin D levels to begin with."

Benign paroxysmal positional vertigo happens when a change in head position gives you a sudden spinning sensation. It's one of the most common types of vertigo. Treatment includes a doctor performing a series of head movements that shift particles in the ears that cause the vertigo, but the condition tends to recur frequently. About 86% of people with this form of vertigo find that it interrupts their daily life or causes them to miss days at work.

The study looked at 957 people in Korea with benign paroxysmal positional vertigo who were treated successfully with the head movements. The participants were separated into two groups, intervention and observation.
