  • Supplement-Supplement: One supplement affecting another's absorption or effects (e.g., calcium blocking iron absorption)
  • Condition-Supplement: Supplements that may worsen certain health conditions (e.g., ginkgo with bleeding disorders)
  • Dosage-Dependent: Higher doses increasing interaction risk

Common High-Risk Interactions:

  • Blood thinners + Omega-3, Vitamin E, Garlic: Increased bleeding risk
  • Diabetes medications + Chromium, Cinnamon: Risk of low blood sugar
  • Blood pressure medications + Hawthorn, Garlic: Excessive blood pressure reduction
  • Antidepressants + St. John's Wort: Serotonin syndrome risk
  • Thyroid medications + Iron, Calcium: Reduced medication absorption
