I asked ChatGPT but it didn't know for sure. It said:
"David Sinclair, a renowned biologist and longevity researcher, indeed advocates for the use of resveratrol as a potential longevity-promoting supplement. His personal regimen of taking 1 gram of resveratrol per day may seem high compared to dosages suggested by some studies in mice. However, several factors may influence his dosage choice and cycling approach:
Individual Variation: Response to supplements can vary greatly among individuals. What works for one person may not work for another. Sinclair might have found through personal experimentation or observation that 1 gram per day works best for him.
Bioavailability: Resveratrol's bioavailability is a significant concern. The body metabolizes and eliminates it rapidly. Taking a higher dosage might be a strategy to ensure a sufficient amount reaches target tissues.
Human Studies: While mouse studies are valuable for initial insights, human studies provide more relevant data. Sinclair might be basing his dosage on human trials or anecdotal evidence rather than solely on mouse studies.
Personal Experience: Sinclair might have observed positive effects from this dosage in himself or others, which influences his recommendation.
Cycling Strategy: Cycling the supplement, such as skipping it on gym days, could be a strategic decision to avoid potential interactions or interference with exercise-induced signaling pathways. It might also be a way to manage potential tolerance or desensitization to the effects of resveratrol.
Longevity Goals: Sinclair's dosage and cycling strategy might be aligned with his specific longevity goals or theories, which could be based on his extensive research and understanding of aging processes.
Overall, while the dosage and cycling strategy may appear unconventional compared to some research findings, Sinclair likely has valid reasons based on his own research, experience, and observations. As with any supplement regimen, individual variations, personal goals, and responses should be considered."
