Typical dosage: Typically 1-3 grams per day, depending on the formulation.
- Fishy aftertaste

Warfarin is a potent anticoagulant with a narrow therapeutic index, requiring careful monitoring of INR levels to avoid bleeding complications.
Typical dosage: Varies by individual; follow prescriber guidelines.
- Bleeding
- Bruising
- Gastrointestinal upset
- Monitor INR levels regularly; avoid sudden changes in diet, especially regarding vitamin K intake.
Take Omega-3 consistently at the same time each day to maintain stable levels, and consult your healthcare provider regarding the timing of Omega-3 relative to Warfarin doses.
- Blood thinners and antiplatelet drugs, combined with supplements that also slow clotting, can add up and raise the risk of serious bleeding. Watch for unusual bruising, nosebleeds, bleeding gums, or blood in urine or stool, and check with the prescriber who manages your medication before combining. Stop bleeding-risk supplements about 1-2 weeks before any surgery or dental work, and never stop a prescribed blood thinner on your own.
- Regularly monitor INR levels due to potential increased bleeding risk when combining Omega-3 with Warfarin.
