Ginger Extract
Ginger Extract (Zingiber officinale)
A powerful digestive aid that reduces nausea, supports gut motility, and has anti-inflammatory properties.
Ginger has been used for thousands of years across cultures for digestive complaints. Modern research strongly supports its efficacy for nausea (especially pregnancy-related and motion sickness), improved gastric emptying, and anti-inflammatory effects. The active compounds gingerols and shogaols provide most of its therapeutic benefits.
Mechanisms of Action
Anti-Nausea Effect
Blocks serotonin receptors in the gut
Prokinetic Action
Speeds gastric emptying
Anti-inflammatory
Reduces inflammation throughout the body
Recommended Dose
250-1000mg extract daily
Loading: Not required
Optimal Timing
- Before meals for digestion
- 30 min before travel for motion sickness
- As needed for nausea
Take with food
Best Form
Standardized extract (5% gingerols)
Alternatives: Fresh ginger, Ginger tea, Crystallized ginger
Standardized extracts provide consistent gingerol content. Fresh ginger is also effective but dosing is less precise.
Duration
Minimum: 1 weeks
Optimal: 4 weeks
Cycling: Not required
Note: For nausea prevention (motion sickness, morning sickness), take 30 minutes before needed.

Top studies from 40+ peer-reviewed papers
Arruda APN et al. • BMJ open (2019)
“There is very low-certainty evidence regarding the efficacy of both Zingiber officinale and Rosa damascena in reducing vomiting (200 fewer cases per 1000; 288 fewer to 205 fewer), nausea (207 fewer cases per 1000; 333 fewer to 27 fewer) and the need for rescue medication for pain (666 fewer cases per 1000; 580 fewer to 752 more) in patients undergoing either laparoscopic or obstetrical/gynaecological surgeries.”
Key Findings:
- Results suggested a non-statistically significantly reduction in the need for rescue medication for pain (RR 0.52; 95% CI 0.13 to 2.13) with Rosa damascena (damask rose) and ginger compared with placebo in laparoscopic and obstetrical/gynaecological surgery.
- Among our eligible studies, there was no reported evidence on AEs.
- Further research warranted to confirm findings
Pattanittum P et al. • The Cochrane database of systematic reviews (2016)
“There is no high quality evidence to support the effectiveness of any dietary supplement for dysmenorrhoea, and evidence of safety is lacking.”
Key Findings:
- Supplements versus other supplementsThere was no evidence of a difference in effectiveness between ginger and zinc sulphate (MD 0.02 points, 95% CI -0.58 to 0.62; one RCT, 101 women).
- Vitamin B1 may be more effective than fish oil (MD -1.59 points, 95% CI -2.25 to -0.93; one RCT, 120 women).
- There is no high quality evidence to support the effectiveness of any dietary supplement for dysmenorrhoea, and evidence of safety is lacking.
- However for several supplements there was some low quality evidence of effectiveness and more research is justified.
Malcangi G et al. • Nutrients (2025)
“Natural products, including single extracts and polyherbal formulations, provide effective and safe alternatives for managing gingivitis and PD.”
Key Findings:
- Natural products, including single extracts and polyherbal formulations, provide effective and safe alternatives for managing gingivitis and PD.
- Their anti-inflammatory, antimicrobial, and antioxidant properties support their adjunctive role alongside with scaling and root planning therapy (SRP) in periodontal therapy.
- However, further large-scale, long-term studies are needed to standardize formulations and establish optimal protocols.
Jotic A et al. • International journal of molecular sciences (2024)
“However, a lack of data about reliable and efficient compounds used in therapy of different types of otitis media still remains in the literature.”
Key Findings:
- Staphylococcus aureus was the most commonly studied pathogen, followed by Pseudomonas aeruginosa and Haemophilus influenzae.
- Biofilm inhibition only by an examined compound was assessed in six studies; biofilm eradication in four studies, and both biofilm inhibition and biofilm eradication were examined in five studies.
- This systematic review indicates that some compounds like NAC, prebiotics, nanoparticles and MESNA that have significant effects on biofilm are safe and could be researched more extensively for further clinical use.
- However, a lack of data about reliable and efficient compounds used in therapy of different types of otitis media still remains in the literature.
Long Z et al. • Frontiers in immunology (2023)
“Dietary polyphenols may improve DAS28, reduce C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR), and improve oxidative stress, etc.”
Key Findings:
- Dietary polyphenols may improve DAS28, reduce C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR), and improve oxidative stress, etc.
- However, more RCTs are needed to verify or modify the efficacy and safety of dietary polyphenols.
- Further research warranted to confirm findings
