Autism and Cod liver oil

Since I work and have personal experiences with autism, I was doing some research on Cod Liver Oil and Autism. It seems that fish oils are generally good, but Cod Liver Oil has a specific ingredient in it that improves Autism! The feedback I noticed from parents were that they saw a difference within hours from repetitive behaviors. I also found out that it is good for your bones,skin and Osteoporosis which I have. There was one warning I did see. You shouldn't have too much of it. I went to the drugstore and bought the lowest dose. I came home and did some more research about interactions with medicine. I couldn't believe it! It interacted with my son's Enalipril! Since I know that he takes a low dose, I called the cardiologist and I am anxiously awaiting her approval. If you have any comments or opinions on this subject please share.
