Longevity thought‐leaders at SXSW London demonstrate that aging is influenced by lifestyle and community, using precision biomarkers, NAD+ supplements and social events to extend healthy years with targeted, data‐driven interventions.
Key points
Biomarker evidence confirms aging as a malleable process influenced by lifestyle beyond genetics.
Precision medicine panels use individual data—epigenetic clocks, glycan aging—to tailor targeted interventions.
Emerging NAD+ supplementation and community-based ‘Longevity Raves’ combine biochemical and social strategies to extend healthspan.
Why it matters:
This shift toward personalized, lifestyle-driven aging strategies marks a paradigm change from genetic determinism and opens new paths for equitable healthspan interventions.

Healthspan vs. Lifespan
Definitions and importance: Lifespan measures the total years lived, whereas healthspan assesses the duration of life spent in good health free from chronic disease. Many people experience a widening gap between their lifespan and years of healthy living, leading to prolonged periods of poor quality of life. By targeting healthspan, scientists and healthcare providers aim to compress morbidity—reducing the time spent with age-related ailments—and improve overall well-being.
Key factors affecting healthspan:
- Nutritional choices: Diets rich in whole foods, lean proteins, healthy fats and antioxidants support metabolic health and reduce inflammation.
- Physical activity: Regular strength training, aerobic exercise and flexibility work maintain muscle mass, cardiovascular function and joint mobility.
- Sleep quality: Adequate, restorative sleep underpins cognitive performance, hormonal balance and immune resilience.
- Stress management: Techniques such as mindfulness, breathwork and social support help lower chronic cortisol levels that accelerate aging.
- Social connection: Positive relationships and community engagement boost mental health and can trigger neurochemical pathways linked to longevity.
Measuring progress: Individualized biomarkers—including epigenetic clocks, glycan aging assays and metabolomic profiles—track how lifestyle interventions affect biological age versus chronological age. These tools allow for precision adjustments to diet, exercise, supplementation and stress-reduction protocols to optimize healthspan.
NAD+ and Aging
What is NAD+? Nicotinamide adenine dinucleotide (NAD+) is an essential coenzyme found in every cell. It plays a critical role in redox reactions for energy production, supports DNA repair enzymes like PARPs, and regulates key signaling proteins known as sirtuins. As we age, NAD+ levels naturally decline, impairing mitochondrial function and increasing oxidative stress.
Why NAD+ matters for longevity:
- Energy metabolism: NAD+ accepts and donates electrons in metabolic pathways such as glycolysis and the electron transport chain, directly influencing cellular ATP generation.
- DNA repair: Enzymes that maintain genomic stability, including PARPs, depend on NAD+ to fix DNA damage that accumulates with age.
- Sirtuin activation: Sirtuins are NAD+-dependent proteins that regulate inflammation, stress responses and metabolic health, all of which are central to healthy aging.
Supplementation strategies: Researchers are exploring NAD+ precursors—nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN)—to restore intracellular NAD+ pools. Preclinical studies demonstrate improved mitochondrial function, metabolic profiles and markers of cellular aging in animal models. Human trials are underway to establish optimal dosing, safety and long-term efficacy.
Considerations and safety: While early results are promising, supplementation should be guided by biomarker data and medical supervision. Potential interactions with medications or underlying health conditions warrant careful evaluation. Ongoing research aims to clarify best practices for integrating NAD+ modulation into comprehensive longevity protocols.
