What the Research Says
Ginger extract is well-supported by evidence for its applications in gastrointestinal health. It has demonstrated robust efficacy in reducing nausea across various settings, including pregnancy, chemotherapy, and post-surgical recovery. A systematic review and meta-analysis of 12 randomized controlled trials (RCTs) involving 1278 women found that ginger significantly reduced nausea symptoms during pregnancy without affecting vomiting episodes or posing significant risks (Viljoen et al., 2014). Similarly, a large multicenter RCT with 576 chemotherapy patients reported that ginger effectively mitigated acute nausea (Ryan et al., 2012).
The prokinetic effects of ginger are attributed to its ability to antagonize the 5-HT3 receptor, enhance antral contractions, and exert anti-inflammatory properties through gingerols. These mechanisms contribute to its effectiveness in treating nausea and vomiting (Giacosa et al., 2015). Additionally, a systematic review of randomized, double-blind, placebo-controlled studies supports the use of ginger extract for preventing and treating nausea and vomiting (Giacosa et al., 2015).
Beyond its anti-nausea effects, ginger extract has shown promise in other areas. A randomized, double-blind, placebo-controlled trial with 80 overweight adults found that steamed ginger extract significantly reduced body fat, weight, and lipid levels after 12 weeks without adverse effects (Kwon et al., 2026). Another study protocol outlines plans to investigate the impact of ginger root extract on the microbiota-gut-brain axis in individuals with sciatica, highlighting its potential broader applications (Shen et al., 2026).
Overall, ginger extract is a safe and effective supplement for managing nausea and may offer additional benefits in weight management and gut health.
