Common questions about Age Well Science and longevity research
Age Well Science is a research institute and educational organization dedicated to understanding the biology of healthy aging. We compile, analyze, and communicate peer-reviewed research on longevity, cellular health, and the biological processes that influence how we age. Our mission is to make complex aging science accessible to the public while maintaining rigorous scientific standards.
Age Well Science is operated by independent researchers and science communicators who specialize in gerontology and aging biology. Our team reviews published research from leading scientific journals and translates findings into accessible educational content. We maintain independence from commercial interests to ensure objective, science-based information.
No, absolutely not. Age Well Science provides educational information about aging biology and research. Nothing on this site constitutes medical advice, diagnosis, or treatment recommendations. We are not medical practitioners, and our content should never replace consultation with qualified healthcare professionals. All health decisions should be made in partnership with your medical providers.
No. We do not sell, endorse, or promote any products, supplements, treatments, or commercial services. Age Well Science is purely educational. We present what research shows about aging biology without making product recommendations or health claims. We are not affiliated with supplement companies, pharmaceutical firms, or commercial interests in the longevity space.
Age Well Science operates as an independent 501(c)(3) educational organization. We are not affiliated with pharmaceutical companies, supplement manufacturers, medical institutions, or commercial entities. This independence allows us to present research objectively without commercial bias. We do not accept advertising, sponsorships, or payments that could influence our content.
We use rigorous criteria to assess research before including it in our content:
We clearly distinguish between preliminary findings and well-established science.
Yes, always. Every scientific claim on our site is backed by citations to peer-reviewed research. We provide PubMed IDs, DOIs, and journal references so readers can verify our sources and examine the original research. We believe in transparency and encourage critical evaluation of all scientific information, including ours.
When research findings conflict, we present both sides and explain the nature of the disagreement. Science is an iterative process, and conflicting results are common, especially in emerging fields. We acknowledge uncertainties, discuss limitations, and avoid cherry-picking studies that support a predetermined narrative. Our goal is to represent the current state of knowledge accurately, including its complexities and contradictions.
Yes. The field of longevity science evolves rapidly, with new findings published regularly. We review emerging research and update our content to reflect the current scientific consensus. Major updates are noted with revision dates. We believe in maintaining accuracy as scientific understanding advances.
Cellular senescence is a state where cells stop dividing but don't die. These senescent cells accumulate with age and secrete inflammatory molecules that can damage surrounding tissue—a phenomenon called the senescence-associated secretory phenotype (SASP). Research suggests that accumulation of senescent cells contributes to age-related tissue dysfunction, inflammation, and various age-related pathologies.
The field of senolytics—compounds that selectively remove senescent cells—has shown promise in preclinical studies and is now being tested in human trials.
Telomeres are protective DNA sequences at the ends of chromosomes that shorten with each cell division. When telomeres become critically short, cells can no longer divide and may become senescent or die. Telomere shortening is considered one of the hallmarks of aging.
Factors that influence telomere length include:
However, the relationship between telomere length and lifespan is complex and not fully understood.
Epigenetic aging refers to age-related changes in gene expression that occur without changes to the DNA sequence itself. These changes primarily involve DNA methylation—chemical modifications that affect which genes are turned on or off.
Scientists have developed "epigenetic clocks" that measure biological age based on DNA methylation patterns. These clocks can predict health outcomes and sometimes show that biological age differs from chronological age. Research explores whether lifestyle interventions or treatments might slow epigenetic aging.
This is an area of active research without definitive answers. Some studies suggest certain interventions may slow biological aging markers or improve age-related biomarkers:
However, "reversing" aging is not well-defined scientifically. Most research focuses on extending healthspan—the period of life spent in good health—rather than reversing chronological age.
Autophagy is a cellular "housekeeping" process that removes and recycles damaged proteins, organelles, and other cellular components. It's essential for maintaining cellular health and function. Autophagy activity declines with age, which may contribute to the accumulation of cellular damage.
Research has examined interventions that may enhance autophagy, including intermittent fasting, caloric restriction, and certain compounds. However, the long-term effects of manipulating autophagy in humans are not yet fully understood.
Chronic low-grade inflammation increases with age, a phenomenon scientists call "inflammaging." This persistent inflammation is associated with numerous age-related diseases, including cardiovascular disease, diabetes, neurodegenerative conditions, and cancer.
Sources of age-related inflammation include:
Understanding and potentially reducing inflammaging is a major focus of aging research.
This is an important distinction: while several interventions extend lifespan in model organisms (yeast, worms, flies, mice), proven lifespan extension in humans is more limited. The interventions with the strongest evidence for improving human healthspan and potentially lifespan include:
Many promising interventions (senolytics, NAD+ precursors, metformin, rapamycin) are still being studied in human trials.
Age Well Science provides educational information about aging biology and longevity research. This information is for educational purposes only and does not constitute medical advice, diagnosis, or treatment recommendations. The field of longevity science is rapidly evolving, and interventions discussed may not have established safety profiles or regulatory approval for anti-aging purposes.
Individual health outcomes are influenced by numerous genetic, environmental, and behavioral factors. Always consult qualified healthcare professionals before making changes to your health regimen, starting supplements, or implementing lifestyle modifications.
