Ginger plus vitamin B6 capsules for travel nausea. Ginger is a genuine antiemetic in pregnancy and after surgery, but its record specifically for motion sickness is old, small and contradictory.

What the science says

  • Ginger for seasickness and motion sickness Limited evidence

    A randomised controlled trial in 80 naval cadets on the open sea found ginger root reduced vomiting and cold sweating compared with placebo. A later comparison of seven commonly used seasickness agents ranked ginger among the weaker options, and laboratory studies using vestibular stimulation have often found no effect.

  • Ginger and B6 for nausea in pregnancy Moderate evidence

    A systematic review and network meta-analysis of interventions for nausea and vomiting in pregnancy found both ginger and pyridoxine (vitamin B6) outperformed placebo, though they ranked below prescription antiemetics. This is the best-supported use of the two ingredients, and it is not motion sickness.

  • The combination products Limited evidence

    No commercial ginger-plus-B6 travel formula has been tested in a randomised trial, and no study has shown the two work better together than either alone for motion sickness.

Dosage & safety

Studied doseThe seasickness trial used 1 g of powdered ginger root roughly 30 minutes before departure. Pregnancy trials used 1-1.5 g/day of ginger in divided doses and 10-25 mg of vitamin B6 three times daily.
SafetyGinger can cause heartburn and, at high doses, may affect platelet function, so discuss it with your doctor if you take anticoagulants or are near surgery. Vitamin B6 above roughly 100 mg/day over extended periods can cause sensory peripheral neuropathy; check that a travel formula is not stacking B6 on top of a multivitamin. Ginger is considered acceptable in pregnancy at the doses studied, but confirm with your obstetric team. For severe or long journeys, scopolamine and antihistamines have far stronger evidence.

How to take it

TimingTake it about 30 minutes before departure, not once you already feel sick.
With food?Take it with a light snack, since concentrated ginger commonly causes heartburn on an empty stomach.
Worth knowingOnce nausea has started, stomach emptying slows and oral absorption becomes unreliable, which is why prevention beats rescue here.

Interactions

With medications

  • warfarin and other anticoagulants or antiplatelet drugs

    High-dose ginger may affect platelet function and add to bleeding risk. talk to your doctor before regular use, and stop before surgery

With other supplements

  • multivitamins and B-complex products containing vitamin B6

    Stacked B6 can push you over the level where long-term use causes sensory nerve damage. add up total B6 across all products and keep it well under 100 mg/day

Well-established interactions only — this is not a complete list. Always tell your doctor and pharmacist what you take.

Frequently asked questions

Does ginger work for motion sickness?

Ginger has limited evidence for motion sickness: one trial in 80 naval cadets found 1 g of ginger root reduced vomiting and cold sweating at sea, but a comparison of seasickness agents ranked ginger among the weaker options and lab studies often found no effect. No ginger-plus-B6 motion sickness formula has been tested in a trial.

When should I take a motion sickness supplement?

Take a ginger-based motion sickness formula about 30 minutes before departure with a light snack, not once you already feel sick. Once nausea starts, stomach emptying slows and oral absorption becomes unreliable.

Do ginger and B6 help nausea in pregnancy?

Ginger and vitamin B6 both outperformed placebo for pregnancy nausea in a network meta-analysis (moderate evidence), though they ranked below prescription antiemetics. Trials used 1–1.5 g/day of ginger and 10–25 mg of B6 three times daily; confirm with your obstetric team.

What works better than ginger for seasickness?

For severe or long journeys, scopolamine and antihistamines have far stronger evidence than ginger-based motion sickness formulas. Keep total B6 across all products well under 100 mg/day, and talk to your doctor about ginger if you take anticoagulants.
