I’m sorry, your Eliquis is already helping thin the blood. I don’t know if it is doing so in the same way as the fish oil or aspirin would, but Omega-3s are needed as an essential fat, anyway, so unless your doctor said you can’t eat salmon, it should be fine.
A 3 ounce portion of sockeye salmon with skin would get you close to four grams of Omega-3, too.
