Narrator: This is Science Today. Scientists at the University of California, Berkeley have found that there are many genetic differences that make people's enzymes less efficient than normal. Genetics professor Jasper Rine says they found that just taking vitamin supplements can restore some of these deficient enzymes to full working order. Rine says the sequencing of the human genome has paved the way for personalized genome sequencing in the future.

Rine: We will have the reference information that people will need to be able to take charge of their own personalized nutrition. This is a form of personalized medicine and personalized genetics that each consumer will have the opportunity to make their own decisions on and act on in ways that will no doubt improve their health.

Narrator: Rine says he's been very gratified by the power of modern biomedical research.

Rine: The time between when one has the inspiration to try something new and the time which you can actually test the idea and try to act upon it, is really short. We can have an idea, test its validity and then reduce it to practice in a very short period of time. That really thrills me.
