Many of them die because they fight, Gorbunova says. National Geographic: Can aging be cured? What sets NR apart from Niacin (NA) is that it has a slightly different structure, enabling the cell to skip an otherwise necessary step in the production of NAD+ and instead use the salvage pathway[2,3]. This is perhaps the reason that NR does not have some of the common side-effects associated with Niacin, i.e. National Geographic writer and explorer Dan Buettner studies the world's longest-lived peoples and their lifestyles. This pursuit was significantly ramped up 30 years ago when Cynthia Kanyon could adjust a gene of tiny roundworms that enabled the doubling of their life.
