β Frequently Asked Questions
Dr. Sinclair considers NMN (Nicotinamide Mononucleotide) his top anti-aging supplement. He takes 1,000mg daily to boost NAD+ levels, which decline with age and are crucial for cellular energy production and DNA repair.
No, Dr. Sinclair doesn’t endorse specific brands. He focuses on the active ingredients rather than particular manufacturers. Look for third-party tested, high-purity supplements from reputable companies.
Resveratrol and other fat-soluble compounds are better absorbed when taken with fats. Yogurt provides the necessary fats for optimal absorption while being a healthy breakfast option.
No, Metformin requires a prescription. Some people use Berberine as a natural alternative that may provide similar metabolic benefits, but consult your healthcare provider first.
The core supplements (NMN, Resveratrol, Fisetin, Quercetin) typically cost $200-400 per month, depending on quality and brands chosen. Prescription medications like Metformin add additional costs.
Dr. Sinclair suggests that NAD+ levels begin declining in the 30s, but there’s no universal starting age. Consult with a healthcare provider to determine if these supplements are appropriate for your age and health status.
π₯ Dr. Sinclair’s Diet and Lifestyle Integration
Supplements work best when combined with healthy lifestyle practices. Dr. Sinclair follows:
π½οΈ Intermittent Fasting
Only two meals per day, often skipping breakfast to extend fasting periods
πββοΈ Regular Exercise
High-intensity interval training and strength exercises to activate longevity pathways
π΅ Green Tea
Rich in polyphenols and EGCG, which complement his supplement regimen
βοΈ Cold Exposure
Regular cold exposure to activate brown fat and stress response pathways
