Dr. David Sinclair, an internationally acclaimed genetic professor at the Harvard Medical School, first discovered resveratrol as an anti-aging agent and subsequently NMN (Nicotinamide MonoNucleotide), another anti-aging agent but more effective in reversing aging cells in our bodies. He started taking 1000mg of NMN daily in 2013. When he was interviewed in 2022, as shown in the before and after photographs, his physical appearance looks significantly younger than in 2013.
