Question 1

What is longevity science?

Accepted Answer

Longevity science studies the biological mechanisms of aging and develops interventions to extend healthy lifespan. It encompasses nutrition, exercise, supplements, genetic testing, and emerging therapies aimed at slowing or reversing age-related decline.

Question 2

What are the most evidence-based longevity supplements?

Accepted Answer

The most researched longevity supplements include NMN and NR (NAD+ precursors), resveratrol, spermidine, omega-3 fatty acids, vitamin D, and magnesium. Emerging compounds like rapamycin and metformin are being studied in clinical trials.

Question 3

How can I measure my biological age?

Accepted Answer

Biological age can be measured through epigenetic clocks (DNA methylation tests like TruAge), blood biomarker panels (InsideTracker), telomere length tests, and comprehensive metabolic panels. These provide more meaningful health data than chronological age.

Question 4

Is it possible to reverse aging?

Accepted Answer

Partial age reversal has been demonstrated in animal studies and early human trials. Practical interventions like exercise, caloric restriction, quality sleep, and certain supplements can measurably reduce biological age markers. Full reversal remains a research frontier.
