Curcumin
Also known as: Turmeric extract (joint), Curcumin (Systemic Inflammation), Turmeric extract (systemic), Curcumin (GI/IBD Support), CuroWhite™ Curcumin Extract (Curcuma longa)
Overview
Curcumin is the primary active polyphenol from turmeric (Curcuma longa) with well-established anti-inflammatory and antioxidant properties supported by numerous clinical studies. Standardized extracts like CuroWhite™ (25% curcuminoids) are designed to improve bioavailability over whole turmeric powder.

Compare Forms
6 formsDifferent chemical forms vary in absorption, side effects, and best use cases. Higher bioavailability scores indicate better absorption.
Curcumin Phytosome (Meriva)
HIGH 100Curcumin complexed with phosphatidylcholine
💡 ~29x higher than unformulated curcumin. Best clinical data of any branded form.
- • Best joint-pain trial data
- • Lower effective dose (~1000 mg/day)
- • Well-tolerated
- • Expensive
- • Contains soy lecithin
📝 Best evidence-based choice for OA pain. Indena's branded Meriva is the studied form.
Longvida Optimized Curcumin
HIGH 95Solid lipid particle technology for free curcumin in plasma
💡 ~285x systemic bioavailability vs standard curcumin; uniquely produces free curcumin in blood.
- • Brain-relevant research
- • Free (active) curcumin in plasma
- • Lower dose
- • Expensive
- • Best for cognitive use cases specifically
📝 Unique for neurological applications. Verdure Sciences' branded form.
Theracurmin (Submicron Particles)
HIGH 90Submicron-particle curcumin colloidal dispersion
💡 ~27x bioavailability vs standard. Studied in heart-health trials.
- • Good cardiovascular trial data
- • Water-dispersible
- • Expensive
- • Branded supply only
📝 Strong CV evidence. Theravalues' branded form.
BCM-95 / Curcugreen
HIGH 85Curcumin combined with turmeric essential oils (ar-turmerone)
💡 ~7x standard curcumin. Essential oils enhance uptake naturally.
- • Natural enhancer (no synthetic carrier)
- • Good general bioavailability
- • Less than phytosome/Longvida
📝 Solid mid-tier option. Used in mood/depression trials.
Curcumin 95% + Piperine
GOOD 75Standardized 95% curcuminoids with black pepper extract
💡 ~20x with piperine vs without; still well below phytosome forms.
- • Affordable
- • Most common form on shelves
- • Decent absorption boost from piperine
- • Piperine can interact with many drugs (CYP3A4 inhibition)
- • Less potent than branded forms
📝 Watch drug interactions due to piperine. Consider Meriva if on medications.
Standard Curcumin 95% (no enhancer)
LOW 40Plain standardized curcuminoid extract
💡 Very poor (~1% bioavailability). Most is excreted unabsorbed.
- • Cheapest
- • Most of the dose is wasted
- • Need very high doses to work
📝 Not recommended without an absorption enhancer. Choose Meriva, Longvida, or piperine.

OA, inflammatory joint conditions
Research & Studies
Landmark clinical studies on Curcumin. Each title links to a plain-English breakdown — what the study shows, what its limitations are, and how to read around them.
- Efficacy and safety of curcumin for osteoarthritis of the knee: 4-week study compared to ibuprofenKuptniratsaikul V, Dajpratham P, Taechaarpornkul W, et al. · 2014 · Clinical Interventions in AgingRCTPubMed ↗
4-week non-inferiority RCT (n=367) found C. longa extract 1500mg/day produced similar pain and function improvements to ibuprofen 1200mg/day, with fewer GI adverse events.
- Curcuminoid treatment for knee osteoarthritis: a randomized double-blind placebo-controlled trial
6-week RCT (n=40) found 1500mg/day curcuminoids (equivalent to high-absorption phytosome) significantly reduced WOMAC pain, stiffness, and physical function scores vs placebo.
