Curcumin : Ulcerative Colitis (UC)
B エビデンス 少なくとも1件のランダム化試験がこれを支持しており、おおむね一貫した結果が得られています。Multicenter RCT (CUBE trial) showed curcumin (2 g/day) plus mesalamine maintained remission better than mesalamine alone. Reduced relapse rate from 20% to 5% over 12 months.
結論

Safety & Side Effects
報告されている副作用
- ⚠ GI discomfort (nausea, diarrhea, abdominal pain) at high doses
- ⚠ Yellow staining of skin/teeth with topical/oral contact
- ⚠ Increased gallbladder contractions (avoid with gallstones or bile duct obstruction)
- ⚠ Iron chelation (may reduce iron absorption at very high doses)
既知の相互作用
- ● 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)
耐容上限摂取量: Well-tolerated up to 8 g/day in clinical trials (most studies use 1-2 g/day)
