Is there any vitamin or supplement recommended for staving off macular degeneration in someone whose father suffered from it? (Lycopene?) Also, separate question: What is the evidence about the benefits if any of SAM-e? One book by three physicians which was recommended to me by a physician endorses SAM-E: http://www.amazon.com/Herbs-Nutrients-Yoga-Mental-Health/dp/039370744X/ref=sr_1_fkmr1_2?s=books&ie=UTF8&qid=1369341712&sr=1-2-fkmr1&keywords=herbs+yoga+M.D. Thanks for any comments.
