David Sinclair
Harvard geneticist; longevity researcher
David Sinclair is a Harvard Medical School geneticist and one of the most prominent — and most debated — scientists in longevity. He is the public face of NAD+ boosting: he takes a gram of NMN daily and has argued it roughly doubles the NAD+ levels that decline with age. Strictly, NMN is a NAD+ precursor (a nucleotide), not a peptide — but his work sits at the center of the NAD+ conversation that runs through this index's celebrity entries. Documented from his book and interviews; his commercial ties to longevity ventures are part of the public record.
NMN, NR, Resveratrol & Other Longevity Molecules — Lifespan #4
I take one gram of NMN every morning along with my resveratrol… in humans we know that doubles NAD levels.
Takes 1 g each morning; argues it doubles age-declined NAD+. A NAD+ precursor, not a peptide.
The coenzyme his protocol aims to restore — the throughline to the celebrity NAD+ trend.
Taken alongside NMN in his long-standing personal regimen.
