Ginger — strongest evidence for motion-related vertigo
Ginger has solid clinical evidence for motion sickness and reducing nausea associated with vertigo. Standardized extracts (Gingever) work better than generic powders.
Ginkgo Biloba — for circulation-related dizziness
Ginkgo improves microcirculation and has moderate evidence for vertigo of vascular origin and tinnitus-associated dizziness. Effects build over 8-12 weeks.
B12 & Folate — for deficiency-related dizziness
B12 deficiency commonly causes dizziness, balance problems, and gait instability — particularly in older adults and vegetarians. Methylcobalamin is preferred for symptomatic deficiency.
Iron — for anemia-related lightheadedness
Iron-deficiency anemia is a common cause of lightheadedness, especially in menstruating women. Ferrous bisglycinate is gentler on the stomach than sulfate.
Magnesium — for vestibular migraine
Vestibular migraine (migraine-related vertigo) responds to the same magnesium prophylaxis as classic migraine. AHS lists magnesium at Level B evidence for migraine prevention.
Hydration & Electrolytes — for dehydration dizziness
Mild dehydration is a common, often-overlooked cause of dizziness on standing. Electrolyte support matters, especially in active people, hot climates, or with reduced fluid intake.
Vitamin D — for postural dizziness
Vitamin D deficiency is associated with BPPV (benign paroxysmal positional vertigo) recurrence. Correcting deficiency reduces BPPV recurrence risk in some studies.
Frequently Asked Questions
What is the best supplement for vertigo?
It depends on the cause. For motion-related vertigo and nausea: ginger 500-1,000 mg before triggering activities. For B12 deficiency-related dizziness: methylcobalamin 1,000 mcg/day. For vestibular migraine: magnesium 400-600 mg/day plus riboflavin. For BPPV recurrence: correcting vitamin D deficiency. Vertigo isn't one condition — match the supplement to the underlying cause.
Does ginkgo really help with vertigo?
Modestly, for vertigo of vascular origin. Ginkgo at 120-240 mg/day standardized extract (EGb 761) shows moderate improvement in vertigo symptoms in older adults with circulatory contributions. Less effective for BPPV or pure inner ear vertigo. Effects build over 8-12 weeks. Reasonable trial when other causes are ruled out.
When is dizziness an emergency?
Sudden severe vertigo with: trouble speaking or walking, facial drooping, weakness on one side, severe headache, or chest pain — call 911 (possible stroke). Other red flags requiring same-day medical attention: vertigo with high fever, vertigo after head injury, vertigo with new hearing loss, or vertigo with vomiting that prevents fluid intake. Most vertigo is benign, but new severe vertigo warrants evaluation.
Could my dizziness be from a B12 deficiency?
Possibly, especially if you're over 50, vegetarian/vegan, on metformin, or on long-term acid blockers (PPIs). B12 deficiency causes dizziness, balance problems, tingling, and cognitive symptoms. A simple blood test confirms it. If deficient, methylcobalamin or sublingual B12 reverses symptoms over weeks. Don't self-treat with high-dose B12 without testing first — masking actual deficiency without treating its cause (often impaired absorption) creates problems.
Does dehydration cause dizziness?
Yes, very commonly. Even mild dehydration (1-2% body weight loss) reduces blood volume enough to cause dizziness on standing (orthostatic dizziness). Older adults are especially vulnerable. If you get dizzy when standing up quickly, especially in mornings or after exercise, try increasing water and electrolyte intake first. If symptoms persist with adequate hydration, see a doctor.
When should I see a doctor about vertigo?
See a doctor for: vertigo lasting more than a few days, recurring vertigo episodes, vertigo with hearing loss or tinnitus (possible Meniere's), severe vertigo causing falls, new-onset vertigo in someone over 50, or vertigo with neurologic symptoms. ENT specialists and vestibular physical therapists have specific treatments (Epley maneuver for BPPV, vestibular rehabilitation, Meniere's management) that work far better than supplements for established conditions.
