Longevity
Longevity is not about living longer. It is about functioning at your best for as long as possible.
Key takeaways
- Healthspan, not lifespan, is the target: how long you function well.
- The processes that drive aging are measurable now, before they are symptomatic.
- VO2 max, muscle mass, ApoB, hsCRP, and blood pressure carry more weight than any supplement.
- The best window to start is while things still look fine.
Longevity, in this context, means the biological processes that determine how well your body ages, things like cellular repair, inflammation, and energy production, tracked and supported before they become symptomatic.
Cellular senescence, NAD+ decline, mitochondrial dysfunction, chronic low grade inflammation, and declining growth factor signaling are each measurable. Baseline tracks the markers that reflect these processes.
The longevity interventions with the most research support work best when started before dysfunction becomes symptomatic. People who are functioning well at 45 and want to maintain that through 65 are exactly who this is built for.
Biomarkers tracked here: IGF-1, hsCRP, Homocysteine, Lp(a), ApoB, Cystatin C, Vitamin D, B12, Folate, MMA, Omega Panel, HRV. Full detail on each in the Biomarker Hub below.
The measurable side of aging
Aging is not a single process. Chronic low-grade inflammation, mitochondrial decline, falling NAD+ availability, cellular senescence, reduced growth-factor signaling, and vascular stiffening each proceed at their own rate and each leave a signature you can measure.
That matters because it makes aging addressable in parts. You cannot act on 'getting older.' You can act on an hsCRP of 2.8, an ApoB of 105, a VO2 max in the bottom quartile, or a homocysteine of 14.
The interventions with the strongest evidence
- Cardiorespiratory fitness. VO2 max is among the strongest single predictors of all-cause mortality, and it is trainable at any age.
- Muscle mass and strength. Lean mass protects against frailty, falls, and metabolic decline in the last two decades of life.
- ApoB reduction. Lifetime arterial exposure to atherogenic particles is cumulative, so lowering it earlier compounds.
- Blood pressure control. Under 120/75 rather than merely under 130/80.
- Metabolic health. Insulin resistance accelerates nearly every other aging process on this list.
- Sleep. The repair window that everything else depends on.
Where supplements and peptides fit
They are the smallest lever, applied after the large ones are in place. Omega-3s for inflammatory load and omega index, vitamin D3 with K2 where deficient, magnesium glycinate for sleep and glucose handling, methylated B-vitamins where homocysteine is elevated. Each is chosen because a marker justified it.
Growth-hormone secretagogue and repair peptide protocols may be appropriate for some people, prescribed by a licensed provider in our network after review. Notably, the IGF-1 target is the middle of the age-adjusted range, not the top, since chronically high IGF-1 carries its own risk.
Tracking over years, not weeks
Longevity work is judged on trend lines. A single panel is a coordinate. Two or three panels across a year are a direction, and direction is what you can steer.
We recommend repeating the same markers on the same cadence so the comparison is honest, and protocol changes should follow the trend rather than a single anecdote.
What this means for you
If you are functioning well at 45 and want the same at 70, start measuring now. The interventions that work best are the ones started before dysfunction is symptomatic.
