The study indicates that taking a vitamin D and calcium supplement is an easy way for preventing recurring vertigo in individuals with benign paroxysmal positional vertigo.

Benign paroxysmal positional vertigo is is one of the most prevalent kinds of vertigo that occurs when changes in a head position give an abrupt sensation of spinning. Treatment includes a health practitioner carrying out several head movements to shift the ear particles that cause vertigo, but the disorder has a tendency to frequently recur.

The researchers examined 957 individuals who had benign paroxysmal positional vertigo and had been successfully treated with the head movements. They were divided into 2 groups, a treatment group, and an observation group.

The 445 individuals in the treatment group had vitamin D levels checked at the beginning of the study. The 348 individuals with levels under 20 ng/mL supplemented with 400 IUs of vitamin D and 500 mgs of calcium twice a day, while individuals with vitamin D levels equivalent to or more than 20 ng/mL weren’t given supplements.

The vitamin D levels of the 512 observation group individuals weren’t monitored and they didn’t get supplements.

Individuals in the treatment group taking the supplements had a lower rate of recurrence for vertigo episodes after 1 year on average compared to the observation group individuals. Those who took supplements had a rate of recurrence of 0.83 times per person-year on average, in comparison to 1.10 times per person-year for the observation group individuals, or a 24% decrease in the rate of annual recurrence.

There seemed to be more of a benefit for individuals who were more vitamin D deficient at the beginning of the study. Individuals who began with vitamin D levels less than 10 ng/mL had a 45% decrease in the rate of annual recurrence, while individuals who started with vitamin D levels at 10 to 20 ng/mL had just a 14% decrease.

A total of 38% of the treatment group individuals had another vertigo episode, in comparison to 47% of the observation group individuals.
