Protocol

Amount

500-2000 mg

Frequency

Divided into 2-3 doses daily, or 30-60 minutes before a nausea trigger

When

For nausea, take 30-60 minutes before travel or in the morning; for pain or digestion, take with meals.

Condition-Based Dosing

Pregnancy-related nausea (1st trimester)

250 mg ginger powder, 4 times daily (total 1 g/day)— Generally regarded as safe at this dose; check with an obstetric provider before use.

Motion sickness

500-1000 mg 30-60 minutes before travel— Prevention works better than treating symptoms after they start.

Primary dysmenorrhea

1500-2000 mg daily for the first 3 days of menses— Start at onset of pain or 1-2 days before the expected period.

Knee osteoarthritis

1000-2000 mg daily in divided doses— Effects may take 3-6 weeks to become noticeable.

Functional dyspepsia / post-meal fullness

250-500 mg 3 times daily before meals— May help fullness and bloating more than reflux.

Post-operative nausea

1000 mg 1 hour before anesthesia— Hospital protocols vary; confirm with the surgical team.

Safety & Limits

Upper Safe Limit

4 g/day dried ginger (highest studied adult dose without serious adverse effects)

Cycling

Safe for continuous use

Contraindications

Warfarin or other anticoagulants — additive antiplatelet effect may increase bleeding risk, especially at high doses

Gallstones or bile duct obstruction — cholagogic effect may trigger colic

Upcoming surgery — stop 1-2 weeks before due to possible bleeding risk at higher doses

Synergies

Vitamin B6

Vitamin B6 and ginger are often combined for pregnancy-related nausea and act through different antiemetic pathways.
