Your biological age isn't a black box — it maps to the specific mechanisms that drive how you age. Here's every one of them in plain language, the biomarkers that reveal them, and what the evidence actually supports doing about it.
These are the biological processes the field has converged on as the actual drivers of aging. Every point in your Gyotta score traces back to one or more of them.
DNA damage and mutation accumulation outpace repair, especially in mitochondria and stem cells.
Protective chromosome caps shorten with each division, eventually triggering senescence.
DNA-methylation and histone marks drift with age; "epigenetic age" tracks this drift.
Misfolded protein clearance declines — central to neurodegeneration.
Aged cells clear damaged organelles less efficiently.
mTOR / IGF-1 / AMPK / sirtuin balance shifts; the basis of caloric-restriction biology.
Energy production drops; reactive-oxygen species and damaged mitochondria accumulate.
"Zombie" cells that won't divide and won't die secrete inflammatory signals (SASP).
Tissue repair slows as stem-cell pools deplete and lose function.
Inflammaging — chronic low-grade inflammation rewires tissue signaling.
Persistent immune activation drives heart, brain, metabolic, and joint disease.
Gut-microbiome shifts feed back into immunity, metabolism, and cognition.
The longevity supplement market runs on hype. This is our honest read of where the evidence stands — including the ones we think are overrated.
How we grade: Strong = consistent human RCT evidence. Moderate = real effects, smaller or mixed trials. Emerging = promising mechanism, human data still thin. Prescription = requires a clinician. Nothing here is medical advice — talk to your doctor before starting anything.
Hallmarks are mechanisms — biomarkers are how we see them from the outside. These are the signals that move your score the most.
The clearest blood signal of "inflammaging" — and one of the strongest movers of your number.
Where your metabolism sits today. Creeping glucose adds years quietly, long before diagnosis.
Cardiorespiratory reserve — arguably the single best predictor of all-cause mortality we have.
Quiet whole-body markers sitting in a routine panel most people never think to read.
The field moves fast. These are the papers currently shaping how we think about measuring — and moving — biological age.
Ten organ-specific clocks validated across Chinese and US cohorts — brain aging emerged as the strongest single predictor of mortality.
A 24-year longitudinal cohort shows the pace of aging — not just where you start — forecasts when disease arrives.
A state-of-the-art review of how proteomic and epigenetic clocks are moving from research into real clinical decisions.
Early data suggest senolytic compounds can lower epigenetic-age markers and reduce systemic inflammation in older adults.
