Conflicts of interest
- Co-founded Sirtris (resveratrol → GSK $720M); flagship compounds failed/were discontinued
- Co-founder Metro Intl Biotech (pharma-grade NMN) — direct interest in NMN's status
- Co-founder Tally Health (epigenetic 'biological age' tests) + ~30 longevity-company roles
Stated factually. Conflicts do not by themselves make a claim wrong; they are context for weighing it.
