Yes, cod liver oil, or CLO for short. I've been reading about its health benefits, and even tried to consume it daily, but just couldn't get past the ick factor, regardless of the health that might come from it. I'm encouraged to try again after reading this review at Kitchen Stewardship, but the giveaway would be helpful. The good stuff is expensive, so it makes it harder to part with the cash and then not be able to "stomach" it. Her review is funny and uplifting, so take the time to read it.
In my defense, I am taking a high Vitamin A capsule daily, and that's one of the nutrients in CLO. What about you?
