Safety & Side Effects

Gemeldete Nebenwirkungen

  • 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)

Bekannte Wechselwirkungen

  • 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)

Tolerierbare Höchstaufnahmemenge: Well-tolerated up to 8 g/day in clinical trials (most studies use 1-2 g/day)
