Vitamin health of future generations?

I read an interesting article today in the San Francisco Chronicle. UC Berkeley scientists are researching the idea of looking at a person's genes and using vitamins as treatments for their specific genetic flaws. Currently, people with or at risk for age-related macular degeneration take a compilation of high amounts of vitamins A, C, E, copper and zinc (AREDS formula). Those with osteoarthritis are recommended to take glucosamine supplements. This article points to research that would take this to a whole new level. Could personalized vitamins be the wave of the future?
