David Sinclair, PhD, a Harvard professor and leading researcher in aging, has become a prominent figure in the longevity space. His work focuses on understanding why we age and, crucially, how to slow or even reverse the process. A significant part of public interest stems from his personal supplement regimen, sparking debate and curiosity. This article details Sinclair’s commonly discussed supplements, the science behind them, and important considerations.
The Core Four (and Beyond)
Sinclair frequently discusses a core set of supplements he takes daily. It’s vital to remember he emphasizes these are his choices, based on his research and individual needs, and aren’t necessarily a universal prescription. Consult a healthcare professional before starting any new supplement routine.
NMN (Nicotinamide Mononucleotide)
What it is: A precursor to NAD+, a coenzyme vital for cellular energy production and DNA repair. NAD+ levels decline with age.
The Science: Sinclair’s research heavily involves NAD+. Boosting NAD+ levels in mice has shown improvements in various age-related conditions. NMN is believed to be a more efficient way to raise NAD+ than simply taking nicotinamide riboside (NR).
Dosage (Sinclair’s reported): Varies, but often around 1000mg daily.
Resveratrol
What it is: A polyphenol found in grapes, red wine, and berries. It’s a sirtuin activator.
The Science: Sirtuins are proteins linked to longevity and cellular health. Resveratrol activates these proteins, potentially mimicking the benefits of calorie restriction.
Dosage (Sinclair’s reported): Typically combined with NMN, around 500mg.
Betaine (Trimethylglycine)
What it is: An amino acid derivative found in beets and spinach.
The Science: Supports methylation, a crucial process for DNA health and gene expression. May also improve liver function.
Dosage (Sinclair’s reported): 1000-2000mg daily.
Vitamin D3 + K2
What it is: Vitamin D3 is essential for calcium absorption and immune function. K2 directs calcium to bones and teeth, preventing arterial calcification.
The Science: Many people are deficient in Vitamin D. K2 enhances D3’s benefits, particularly for cardiovascular health.
Dosage (Sinclair’s reported): 5000 IU D3 + 100mcg K2.
Other Supplements Sinclair Mentions
- Metformin: A diabetes drug sometimes used off-label for longevity (requires prescription).
- Fisetin: A senolytic – clears senescent (zombie) cells.
- Spermidine: Another compound promoting autophagy (cellular cleanup).
- Creatine: For muscle health and cognitive function.
Important Considerations & Disclaimer
Quality Matters: Supplement quality varies drastically. Choose reputable brands with third-party testing.
Individual Needs: Sinclair’s regimen is tailored to him. Your needs may differ based on genetics, lifestyle, and health status.
Not a Magic Bullet: Supplements are additions to a healthy lifestyle – diet, exercise, sleep, and stress management are paramount.
Ongoing Research: The science of longevity is evolving. Stay informed about new findings.
