What do you mean by "skin food"? I do take vit C and zinc. I can't take cod liver oil because I am allergic to codfish, but I take flax seed oil, and emergen-C. I will try the GCG and let you know how I do on that, but I don't really get gallbladder attacks, I just have an off and on very dull achiness in that area and the constant nausea.
