Vitamin D and calcium for repeat inner-ear vertigo
Part of Brain & nervous system, Ear, nose & throat, Hormones & metabolism clinical trials.
This trial looks at whether taking vitamin D and calcium can reduce repeat episodes of benign paroxysmal positional vertigo (BPPV), a type of brief spinning dizziness caused by inner-ear crystal movement. If your dizziness keeps coming back, this may help prevent future episodes.
Summary written for real people, not researchers, by Clin2.

This trial tests a new way to treat a common inner ear condition called BPPV that hasn't improved with standard head maneuvers. It aims to help people whose dizziness keeps coming back.
This study looks at people with a common inner ear dizziness problem called BPPV, and compares them to healthy volunteers. It uses brain scans and other tests to learn more about the condition.
This study tests if adding special head exercises (Brandt-Daroff) to two different repositioning maneuvers (Epley or Semont-Plus) helps reduce dizziness and improve quality of life in people with a common inner ear condition called BPPV.
This study tests if chewing gum helps reduce dizziness in people who come to the emergency room with a common type of vertigo caused by loose crystals in the inner ear. If you qualify, you will get the standard medicine for dizziness, and half the participants will also chew gum to see if it makes them feel better faster.
This study tests whether head acupuncture can help with lingering symptoms (like unsteadiness or discomfort) that sometimes remain after a successful repositioning procedure for BPPV, a common cause of vertigo. If you feel better but not fully steady, this treatment might help.
This study checks whether people with Meniere’s disease have different bone density (bone strength) compared with expected patterns. It may help spot bone health risks early, especially if you’re affected by other conditions or medicines that weaken bones.
