Can fish oil cause your heart rate to rise or even your resting heart rate? i get about 2, 000mg of epa and 2, 000mg of dha daily.

Not usually: Fish oil consumption at doses less than 3000 mg is thought to be generally safe, although there are potential interactions with many medications. There are 2 unlikely situations where fish oil might cause increased resting heart rate. First, fish oil can lower blood pressure in some people and might cause heart to beat faster. Second, fish oil might affect clotting, causing bleeding and anemia.
