Dear X: Cholodin is a dietary supplement with the following ingredients: Phosphatidylcholine (from soy lecithin), choline (as chloride), dl- methionine, inositol, zinc (as oxide), niacinamide, vitamin E, thiamine (mononitrate), riboflavin, pyridoxine (HCl), selenium (sodium selenite), vitamin B12 (cobalamin concentrate), and dexpanthenol. Formulated with a flavor base. Unfortunately, without more information on George's liver enzymes, I am unable to confirm the possibility of liver failure. While this supplement is not harmful, I do not see anything in it which would reverse liver failure. Elevated liver enzymes are a common finding in ferrets who are not eating well, and may be misinterpreted to represent primary liver disease. I would be hesitant in ascribing miraculous actions to this particular formulation - I would much rather ascribe them to your wonderful nursing care. With kindest regards, Bruce Williams, DVM [Posted in FML issue 3481]
