How We Chose These Products
We scored every contender on the 5weighted criteria below. Evidence quality and third-party verification carry the most weight; value, clean-label formulation, and transparency round out the score. Where tradeoffs appear — a higher-evidence form that costs more, a research-grade dose in a product with a heavier price tag, a commodity ingredient at a rock-bottom price — the pick that wins on evidence-grade criteria takes the top slot. Business partnerships never move a product's score, and lower-cost non-affiliate alternatives are included when they meet the same evidence bar.
Clinical Evidence for Nausea
35%How directly the ingredient has been tested for nausea endpoints in controlled trials. Ginger carries the strongest evidence (12-RCT meta-analysis, Viljoen et al. 2014; NCI-funded chemotherapy-nausea trial, Ryan et al. 2012). Probiotics and peppermint have more targeted use cases. We weight this criterion highest because many general-purpose digestive supplements have no nausea-specific data.
Bioavailable Form & Clinical Dose
25%Standardized extracts dosed to match published trials (250mg ginger root extract four times daily; 10-25mg vitamin B6 three times daily; 0.2mL enteric-coated peppermint oil). Non-standardized preparations and sub-clinical doses score lower. Enteric coating is specifically required for peppermint oil to reach the small intestine without gastric irritation.
Third-Party Testing & GMP
20%USP, NSF, ConsumerLab, or independent COA verification of identity and potency. Particularly important for ginger products, where gingerol and shogaol concentrations vary widely between suppliers. GMP certification is a baseline requirement.
Pregnancy & Chemotherapy Safety
12%Because two of the highest-volume nausea use cases are morning sickness and chemotherapy-induced nausea, products must have a documented safety profile in these populations. The Natural Medicines database classifies ginger as "likely safe" in pregnancy; vitamin B6 is ACOG first-line. Products lacking pregnancy safety data are penalized.
Value per Clinical Serving
8%Cost per serving at the clinically effective dose, not cost per capsule. A $0.10 capsule delivering a sub-therapeutic dose is worse value than a $0.25 capsule delivering a full clinical dose.

Ginger's anti-nausea effect operates through two mechanisms — 5-HT3 receptor antagonism (the same target as ondansetron) and enhanced gastric emptying. Motility Activator combines standardized ginger with artichoke leaf to amplify the prokinetic side of that mechanism, making it especially effective when nausea is driven by delayed gastric emptying or functional dyspepsia.

ACOG (Obstet Gynecol 2018 Committee Opinion 189) recommends pyridoxine as first-line for NVP. The Matthews et al. 2010 Cochrane review (PMID 20824863) concluded vitamin B6 reduces NVP severity versus placebo. Thorne's P5P is the pre-activated form (pyridoxal-5'-phosphate) — bypasses hepatic conversion and reaches therapeutic levels faster. NSF Certified for Sport is the highest third-party testing tier available for supplements. One capsule every 8 hours totals 99mg P5P per day, approximately equivalent to 75mg pyridoxine — top of ACOG's 30-75mg/day range.

How to Choose
Match the Supplement to the Cause
For pregnancy nausea, the ACOG first-line recommendation is vitamin B6 (pyridoxine) 10-25mg three times daily, either alone or combined with ginger 250mg four times daily — this mirrors the combination that became the prescription drug Diclegis. For chemotherapy-induced nausea, ginger (500mg to 1g daily starting 3 days before treatment) added to the oncologist's standard antiemetic significantly reduced acute nausea severity in the 576-patient Ryan et al. (2012) NCI-funded trial. For motion sickness, 500mg-1g of ginger taken 30-60 minutes before travel is the best-supported protocol. For gut-driven or post-antibiotic nausea, probiotics with Saccharomyces boulardii or Lactobacillus rhamnosus GG have the strongest evidence.
Dose Is the Single Most Important Factor
The most common failure mode for nausea supplements is under-dosing. The 2014 Viljoen meta-analysis used 250mg ginger four times daily (1,000mg total); products delivering 50-100mg per capsule require four or more capsules per day to match that protocol. Vitamin B6 was studied at 10-25mg three times daily; the ubiquitous 100mg "high-potency" B6 supplement actually exceeds the ACOG-recommended daily total and risks peripheral neuropathy at prolonged high doses. Enteric-coated peppermint oil must be 0.2-0.4mL per capsule to match the IBS and postoperative nausea trial protocols.
What Doesn't Work
Homeopathic "nausea relief" products have no clinical evidence beyond placebo. Chamomile tea, despite being commonly recommended, has no controlled trial data for antiemetic effects. Activated charcoal helps with specific poisoning-related nausea but can interfere with medication absorption and has no evidence for other types of nausea. Acupressure wristbands (Sea-Bands) targeting the P6 point show mixed evidence — a Cochrane review concluded low-quality evidence of modest benefit for postoperative nausea, but many trials cannot distinguish effect from placebo. OTC CBD at consumer doses has not been shown to reduce nausea in controlled trials, despite pharmaceutical cannabinoids (dronabinol, nabilone) having FDA approval for chemotherapy nausea at much higher doses.
When to See a Doctor
Persistent nausea lasting more than 48 hours, nausea accompanied by severe abdominal pain, signs of dehydration, bloody vomiting, or projectile vomiting requires medical evaluation rather than supplementation. Pregnancy nausea that prevents adequate fluid intake (hyperemesis gravidarum) requires OB/GYN management. Chemotherapy nausea supplementation should always be discussed with the oncology team first — some supplements have drug interactions with specific regimens.

Frequently Asked Questions
What is the best supplement for nausea overall?
What is the best supplement for nausea overall?
Ginger has the strongest and broadest evidence base of any supplement for nausea, with a 12-RCT meta-analysis (Viljoen et al., 2014) confirming significant reduction in both nausea severity and vomiting episodes across pregnancy, chemotherapy, motion sickness, and postoperative contexts [1]. A separate meta-analysis of postoperative nausea trials confirmed ginger's effect across multiple surgical contexts [3]. The clinically studied dose is 250mg four times daily (1,000mg total). Vitamin B6 is a close second and specifically remains ACOG first-line for morning sickness.
Evidence:Meta-analysis (2014) · 12 RCTs · n=1,278 · high confidence[#1]. See full reference list below.What is the best supplement for morning sickness during pregnancy?
What is the best supplement for morning sickness during pregnancy?
The American College of Obstetricians and Gynecologists recommends vitamin B6 (pyridoxine) at 10-25mg three times daily as first-line treatment for pregnancy-related nausea, based on controlled trials including Sahakian et al. (1991) and Vutyavanich et al. (1995). Ginger (250mg four times daily) is the second-line natural option with strong safety data across 12 RCTs and can be combined with B6. Both have favorable pregnancy safety profiles — ginger is classified "likely safe" by the Natural Medicines database.
Does ginger actually work for nausea?
Does ginger actually work for nausea?
Yes, with strong evidence. Ginger operates through two complementary mechanisms: antagonism of 5-HT3 serotonin receptors in the GI tract — the same target as the prescription antiemetic ondansetron — and enhanced gastric motility via cholinergic and serotonergic pathways. The 2014 Viljoen meta-analysis of 12 RCTs (1,278 pregnant women) found significant reduction in nausea severity versus placebo. The 2012 Ryan NCI-funded chemotherapy trial in 576 cancer patients confirmed ginger added to standard antiemetics significantly reduced acute nausea severity.
How much ginger should I take for nausea?
How much ginger should I take for nausea?
The clinically effective dose across nausea trials is 1,000mg (1g) of ginger daily, typically divided as 250mg four times throughout the day. For motion sickness, 500mg-1g taken 30-60 minutes before triggering activity is most effective. For chemotherapy-induced nausea, Ryan et al. used 500mg-1g daily starting three days before the chemotherapy infusion. Standardized extracts provide more reliable gingerol and shogaol content than dried powder.
Can probiotics help with nausea?
Can probiotics help with nausea?
Evidence is emerging but still preliminary. Probiotics may reduce nausea when the driver is gut microbiome disruption — for example, after antibiotics, during chemotherapy, or in IBS-associated nausea. Saccharomyces boulardii has the strongest evidence for antibiotic-associated GI disturbance, and Lactobacillus/Bifidobacterium blends have suggestive evidence for pregnancy and chemotherapy nausea. Probiotics are not first-line for motion sickness or pure morning sickness, where ginger and B6 remain the stronger choices.
