Caution Advised: Fish Oil and Blood Pressure Drugs May Clash
Cardiologists warn that taking fish oil omega-3 supplements with blood pressure medications can cause mild blood thinning and may lower blood pressure too much, especially at high doses or if the oil is rancid; while often safe with medical guidance, supplements should not replace prescribed meds—discuss use with a clinician, consider dietary omega-3 sources, and monitor for side effects.
