What this score is: a measure of how much research exists and how far along it is (animal-only vs. human trials, research-stage vs. FDA approved) — not how safe, effective, or worth trying a compound is. A low score usually means “early stage” or “understudied,” not “bad.” A high score doesn’t mean “better” for your goals than a lower-scored one.
This is not my personal rating of the compound, not a recommendation, and not medical advice. It’s a general research synthesis for informational purposes only, not a live literature count. See the linked research and talk to a licensed clinician before making decisions based on it.
Mechanism
Curcumin is the primary active compound in turmeric, studied for anti-inflammatory and antioxidant effects through modulation of inflammatory signaling pathways (e.g. NF-kB). Its major practical limitation is very poor natural bioavailability — most positive trial results use enhanced formulations (with piperine/black pepper extract, or phospholipid/liposomal delivery) rather than plain turmeric powder.
Common Protocols
- 500–1000 mg daily of a bioavailability-enhanced formulation, with food
- Plain turmeric powder would need far higher doses to reach comparable blood levels
Side Effects
- GI upset at higher doses
- Rare reports of liver enzyme elevation, mostly with high-dose enhanced formulations — discontinue and seek care for jaundice or unusual fatigue
Interactions
- Mild antiplatelet effect — caution combining with blood thinners
- May increase absorption of other drugs when combined with piperine, which also affects liver drug-metabolizing enzymes
