Supplementing is one of the hot button issues of Paleo. From what I have read, the general consensus is that some need it more than others to heal from SAD or to be more "Optimal".
So with that in mind what "Food Supplement" do you take to try to optimize nutrition?
I've read about Offal (Liver, Heart, Kidney), Fish with bones/skin, Seaweed and Caviar.
If you've read some of my other posts, I am all for optimal but am weary of supplementing. I believe you can get not just "regular" but "optimal" nutrition from food. You may have to go outside your comfort zone about what you consume but I believe it is possible.
I don't want to fall into nutritionism but I agree with Paul of PHDs idea that a lot of diseases are caused by vitamin/mineral deficiencies and can be helped by fixing them.
What real food do you eat that gives you the most bang for you vitamin/mineral buck?
