He's a biologist, and his major discovery was finding a gene that controls aging by experimenting with yeast. Subsequent supporting research has been done on rats as well.

Subsequent supporting research has been done on rats as well. There are 2 important substances at work here. Sirtuins, a protein that regulates aging and other processes at a cellular level. We need them particularly to make nicotinamide adenine dinucleotide (NAD+), a required material for conversion of food into energy and other cell functions. NAD supplies in the body deteriorate over time, though some can come can be gained from certain food substances like tryptophan, aspartic acid and niacin. From this comes the idea of supplementation.
