Why this happens
Atorvastatin works by reducing the amount of cholesterol made by the liver. Cod liver oil contains omega-3 fatty acids, which help lower triglycerides (another type of blood fat). While both can slightly influence how blood cells stick together, this effect is generally not strong enough to cause clinical problems for most people.
What you should do
It is generally safe to take these together. If you are also taking prescribed blood-thinning medication (like warfarin or aspirin), or if you have a planned surgery, you should inform your doctor or pharmacist before starting cod liver oil. Always stick to the recommended dose on the supplement packaging.
