Fish oil has a mild blood‑thinning effect because EPA and DHA influence platelet aggregation. If you are prescribed anticoagulants (e.g. warfarin, apixaban, rivaroxaban) or antiplatelet drugs, adding a concentrated omega‑3 supplement may increase bleeding risk and requires medical supervision — your doctor may want to monitor clotting parameters or adjust the dose. The same caution applies if you have a bleeding disorder or are scheduled for surgery. During pregnancy and breastfeeding, omega‑3 needs change and not all supplements are formulated for those stages; a specialist can confirm whether this product’s EPA/DHA ratio and the added sea buckthorn oil fit your situation. Even without medication, if you have a chronic condition or take multiple supplements, a brief check‑in with a pharmacist or physician helps avoid unintended interactions. The product is a food supplement, not a medicine, and is not intended to diagnose, treat, or prevent any disease.
