Dr. Amy Nett: There are a few different cod liver oils. I think Chris’s favorite is Rosita Real Foods cod liver oil, and it comes both in oil and also capsules. I like the NutraPro International cod liver oil because there there’s a peppermint flavor and a lemon flavor, and it’s just a little bit less fishy, so more and my patients will tolerate it. It doesn’t come in capsules, and it’s also a little bit more cost effective than the Rosita Real Foods cod liver oil. Another capsule option is Dropi Pure Icelandic Cod Liver Oil. That one I’m not as familiar with. I haven’t tried it, but one of my patients actually found it on Amazon when she was desperate for finding capsules before the Rosita Real Foods had capsules. Those are the three that I most often recommend for cod liver oil sources. Generally, for a maintenance dose, it would be about one-half to 1 teaspoon daily depending a little bit on whether or not the patient’s eating organ meats. If you’re using it for more therapeutic purposes, or if someone does have low A, D, and K—remember for the K, you’ll want to do a separate supplement either Thorne K2 drops or maybe some butter oil. But if you’re using it for more of a therapeutic purpose, I will go up to 2 teaspoons daily, but I don’t generally do that long term and not if somebody is otherwise eating a lot of organ meats.
