Mechanism of Action
Gingerols act at multiple levels in the body following oral ingestion. In the digestive system, they stimulate the secretion of pancreatic and biliary enzymes. This accelerates the passage of food through the stomach (gastric emptying), contributing to the reduction of nausea.
At a systemic level, gingerols modulate the production of inflammatory mediators by immune cells. The body reduces pro-inflammatory signals while strengthening regulatory ones, rebalancing the overall response.
Ginger also supports glucose metabolism by promoting cellular sensitivity to blood sugar regulation signals. Its phenolic compounds further contribute to maintaining antioxidant defences by supporting the activity of cellular protection enzymes.
Key Benefits
- Strong
Meta-analyses involving thousands of participants confirm a significant reduction in nausea in pregnancy, postoperative, and motion sickness contexts. The effect is documented at doses of 1 to 2 g per day.
- Strong
Meta-analyses of controlled trials show a significant decrease in C-reactive protein (a blood marker reflecting systemic inflammation levels) in subjects supplemented with ginger extract.
- Strong
Ginger contributes to the normal functioning of the intestinal tract and digestive comfort. This effect is supported by clinical data on gastric emptying and intestinal motility.
- Moderate
Randomized trials in subjects with elevated blood glucose show a reduction in fasting blood glucose and glycated haemoglobin (HbA1c, an indicator of glycemic control over three months). The effect is observed after eight to twelve weeks of supplementation.
- Moderate
A meta-analysis of controlled trials in overweight subjects reports an improved lipid profile, with reductions in total cholesterol and triglycerides.
- Moderate
Randomized clinical trials show a 20 to 25% reduction in delayed-onset muscle soreness in athletes supplemented with ginger after intense exercise.
Dosage & Forms
Ginger is available in several supplementation forms. Dried rhizome powder is the most common form used in clinical trials, at doses of 1,000 to 2,000 mg per day. Standardised gingerol extracts concentrate the active compounds and allow lower doses for equivalent effects. Supercritical CO2 extracts preserve a phytochemical profile close to the fresh rhizome, but production costs are high.
Gingerol bioavailability varies considerably depending on the galenic form. Free gingerols undergo rapid degradation in the acidic gastric environment, reducing their plasma concentration. Among the encapsulation technologies studied, cyclodextrins offer the best balance between gastric protection, solubility, and intestinal release. The dose selected by Singular is calibrated to reach efficacy thresholds documented in trials on inflammatory markers and digestive comfort.
In the Singular Formula
Inclusion rationale
Rhizome of Zingiber officinale, a tropical plant used in Asian culinary and herbal traditions for millennia. Ginger owes its properties to its richness in gingerols and shogaols, pungent phenolic compounds. 6-gingerol is the main bioactive in fresh ginger, while 6-shogaol, produced by thermal dehydration, predominates in dried and concentrated forms. Ginger contributes to digestive comfort and the normal functioning of the intestinal tract. Randomized clinical trials have confirmed its efficacy on nausea in various contexts (motion sickness, postoperative, pregnancy), at doses of 1 to 2 g/day. The warming properties of ginger are linked to the activation of heat-sensing receptors, triggering peripheral vasodilation. Recent meta-analyses have documented significant effects on systemic inflammatory markers (CRP) and glycemic profile. In the formula, ginger is paired with curcumin (also present), another member of the Zingiberaceae botanical family. These two rhizomes, combined for millennia in Asian medicinal traditions, present complementary activity spectra.
Selected form
Ginger rhizome extract (Zingiber officinale), standardised in gingerols, the primary bioactive compounds of the plant. Extraction is performed from the whole rhizome, and the extract is encapsulated in beta-cyclodextrin: a cyclic plant-derived oligosaccharide that forms a molecular cage around gingerols. This encapsulation protects active compounds from oxidation and gastric degradation while improving their aqueous solubility. Ginger has been used for millennia in Ayurvedic and Chinese traditions. Quality: non-GMO, pesticide-free.

Safety & Precautions
Ginger benefits from millennia of culinary use and a well-documented safety profile in clinical trials. At standard supplementation doses (500 to 2,000 mg/day of extract), reported side effects are rare and mild: slight heartburn, belching, or transient gastric discomfort. These effects occur mainly when ginger is taken on an empty stomach.
Ginger supplementation is not recommended for individuals taking anticoagulants or antiplatelet agents without prior advice from a healthcare professional. A potential effect on blood fluidity has been observed in preclinical studies. As a precaution, it is advisable to discontinue supplementation two weeks before scheduled surgery.
During pregnancy, clinical trials have used doses up to 1 g per day without notable adverse effects. Advice from a healthcare professional is nonetheless recommended. In children under six years of age, data are insufficient to make a recommendation.
