HighWhat the studies found
By outcome
Ginger Extract has an evidence score of 9/10 — very strong evidence based on 45 indexed studies, including 15 meta-analyses. Gingerols and shogaols reduce nausea, accelerate gastric emptying, and provide systemic anti-inflammatory benefits.
The commonly studied dose of Ginger Extract is 250-1000mg extract daily. Research points to an estimated optimal dose around 1000mg, with a minimum effective dose near 500mg. Individual response varies — start low and adjust.
The best time to take Ginger Extract is with meals. Take it with food. Ginger (Zingiber officinale) has been used for millennia as a digestive aid.

Note: For nausea prevention (motion sickness, morning sickness), take 30 minutes before needed.
You can get ginger extract from these foods and drinks. Doses are typical per-serving estimates — actual content varies by brand, brew, cooking, etc.
1000 mg per 5 gs
5 g fresh root (about a 1-inch piece). The supplement is a concentrated extract; ratio above assumes ~4% gingerol content in fresh.
Strong evidence from multiple meta-analyses including pregnancy, chemotherapy, and post-operative nausea. Conservative effectiveness estimates due to variable study populations and outcome measures.
Effective for various types of nausea
Faster stomach emptying
Systemic anti-inflammatory effects
Well-studied for morning sickness; keep under 1g/day
May have mild antiplatelet effects — may affect platelet aggregation or vitamin K-dependent clotting factors, altering anticoagulant efficacy
May lower blood sugar; monitor
Tip: Take with food; reduce dose
Tip: Take with food or water
Ginger Extract is generally well-tolerated and considered safe for most healthy adults at recommended doses. The most commonly reported side effects are heartburn, mouth irritation. Use caution if any of these apply to you: Gallstones (high doses may stimulate bile).
