Curcumin
Also known as: turmeric extract, curcuminoids
Recommended Dosage
500–1000 mg
Curcumin is the primary bioactive compound in turmeric, responsible for its anti-inflammatory and antioxidant properties. It modulates multiple molecular targets including NF-κB, COX-2, and various inflammatory cytokines. The major challenge with curcumin is bioavailability — standard curcumin extract is poorly absorbed, rapidly metabolized, and quickly eliminated. Enhanced formulations (with piperine, phospholipids, or nanoparticles) dramatically improve this.
TL;DR: Potent anti-inflammatory from turmeric. Must enhance bioavailability with piperine or specialized formulations.
Evidence Rating: Grade B — Moderate Evidence
Some RCTs with positive results, or strong observational evidence. More research may refine our understanding.
Forms Comparison
Curcumin + Piperine (BioPerine)
~ Moderate AbsorptionBlack pepper extract increases curcumin absorption by ~2000%. Most affordable enhanced option.
Longvida (SLCP)
✓ High AbsorptionSolid lipid curcumin particle technology. Designed to cross the blood-brain barrier.
Meriva (Phytosome)
✓ High AbsorptionCurcumin bound to phosphatidylcholine. 29x better absorption than standard curcumin.
Theracurmin
✓ High AbsorptionNano-particle curcumin with 27x higher bioavailability. Well-studied in clinical trials.
Standard Curcumin 95%
✗ Low AbsorptionUnenhanced extract. Very poor absorption on its own — most passes through unabsorbed.
Interaction Warnings
May increase bleeding risk
May enhance blood sugar lowering
⚠️ Important Notes
- Poor bioavailability without piperine or lipid formulation
- May cause GI issues at high doses
