Curcuma longa extract
Curcumin
Curcumin is the primary bioactive polyphenol extracted from turmeric root. It modulates multiple inflammatory pathways simultaneously - including NF-κB, COX-2, and key cytokines - but its clinical impact depends entirely on the formulation. Standard curcumin without a bioavailability enhancer is poorly absorbed; piperine, phospholipid complexes, and nanoparticle delivery systems can increase absorption by up to 2,000%.
| Decision signal | Ginger Extract | Curcumin |
|---|---|---|
| Evidence grade | Moderate | Moderate |
| Primary health goal | Inflammation & Recovery | Inflammation & Recovery |
| Research focus | Nausea and motion sickness relief; Digestive motility and GI comfort; COX/LOX anti-inflammatory support | Joint comfort and osteoarthritis support; Exercise recovery and DOMS reduction; Systemic inflammation and oxidative stress |
| Studied dose and form | 250–1000 mg standardized extract/day; for nausea, 500–1000 mg before travel or meals. | Curcumin + piperine (BioPerine®) ... 500–1,500 mg curcuminoids + 5–20 mg piperine ... With a fat-containing meal; split into 2 doses if >1,000 mg |
| What to check on the label | Check the label for a clearly named form, disclosed dose and independent testing. | Formulation is everything with curcumin - this is not a supplement where higher milligrams on the label equals better outcomes. A product with 1,500 mg of unformulated 95% curcuminoid extract and no bioavailability enhancer will produce lower serum concentrations than 500 mg of a… |
| Main safety note | May potentiate anticoagulants at high doses; mild heartburn possible; consult in pregnancy beyond culinary amounts. | Curcumin is well tolerated at standard doses; GI upset (nausea, loose stools) is the most common side effect and usually resolves with dose reduction or taking it with food. Curcumin inhibits platelet aggregation and potentiates anticoagulant and antiplatelet medications (warfari… |
