- ⚠ Increased gallbladder contractions (avoid with gallstones or bile duct obstruction)
- ⚠ Iron chelation (may reduce iron absorption at very high doses)
Known Interactions
- ● Anticoagulants (curcumin has antiplatelet properties; may increase bleeding risk)
- ● Chemotherapy agents (curcumin may alter drug metabolism via CYP enzyme inhibition)
- ● Sulfasalazine (additive anti-inflammatory effect — may be beneficial in IBD)
- ● Iron supplements (curcumin may chelate iron; space dosing)
- ● Piperine/black pepper (enhances curcumin bioavailability by 2,000% — commonly co-administered)
Tolerable upper intake: Well-tolerated up to 8 g/day in clinical trials (most studies use 1-2 g/day)
