Is It Safe to Take Fish Oil with Blood Thinners?

Taking fish oil with blood thinners requires medical supervision due to potential interaction risks. Fish oil contains omega-3 fatty acids that can enhance the anticoagulant effects of medications like warfarin, increasing bleeding risk. Studies show omega-3 supplements may prolong bleeding time by 15-20% when combined with anticoagulants. The interaction varies based on fish oil dosage, with higher doses (above 3 grams daily) posing greater concern. Your doctor may need to adjust blood thinner dosages or monitor your INR levels more frequently if you take both supplements. Always consult your healthcare provider before adding fish oil to your medication regimen to ensure safe, personalized dosing.
