an Instagram post<\/a>. \u201cThere are five biomarkers that can predict not just how long you\u2019ll live, but how well.\u201d<\/p>\nIt\u2019s a bold claim, but one that is increasingly backed by emerging science. As Vass puts it, \u201cThese labs give you real insight into how fast you\u2019re aging on a cellular level, long before symptoms appear.\u201d<\/p>\n
Below are the five key biomarkers he considers essential for anyone serious about protecting and extending their healthspan.<\/p>\n
1. ApoB: The silent predictor of cardiovascular risk <\/p>\n
Apolipoprotein B (ApoB) has gained significant traction in longevity and cardiovascular research as a more reliable indicator of heart-disease risk than LDL cholesterol.<\/p>\n
High ApoB means your blood contains more plaque-forming particles \u2013 tiny, dense lipoproteins that can slip into artery walls and accelerate cardiovascular aging.<\/p>\n
Vass calls ApoB the most important blood marker for long-term heart health, advising people to aim for levels below 80 mg\/dL.<\/p>\n
If healthspan had a villain, it would probably be ApoB: quiet, consistent and capable of aging the arteries long before symptoms show.<\/p>\n
2. hs-CRP: A window into hidden inflammation <\/p>\n
High-sensitivity C-reactive protein (hs-CRP) measures low-grade inflammation, often referred to as \u201csilent inflammation\u201d, the kind that slowly erodes long-term health.<\/p>\n
\u201cThis measures silent inflammation, the root of aging, heart disease, Alzheimer\u2019s, and more,\u201d Vass said. \u201cEven a mild elevation signals oxidative stress and immune activation.\u201d<\/p>\n
He recommends keeping hs-CRP below 1.0 mg\/L to support healthier aging and reduce the underlying inflammatory burden that drives many chronic diseases.<\/p>\n
3. VO\u2082 Max: The fitness marker that predicts longevity <\/p>\n
Widely recognized as one of the strongest predictors of all-cause mortality, VO\u2082 Max measures how efficiently your body uses oxygen. Think of it as your fitness engine and longevity fuel.<\/p>\n
According to Vass, \u201cHigher VO\u2082 Max equals longer life, better brain health, and metabolic resilience. The goal is to stay in [the] top 25 percent for your age.\u201d<\/p>\n
VO\u2082 Max naturally declines with age, but improving it is one of the most powerful ways to extend both lifespan and quality of life. Even small gains can have outsized effects.<\/p>\n
4. Fasting insulin: Your metabolism\u2019s early warning system <\/p>\n
Long before blood sugar spikes or diabetes symptoms appear, fasting insulin reveals the earliest signs of metabolic slowdown.<\/p>\n
As Vass puts it, fasting insulin is an \u201cearly warning sign of metabolic dysfunction, even before glucose spikes. Chronically high insulin drives aging, fat gain, and cognitive decline.\u201d<\/p>\n
Optimal levels should fall between 2 and 5 \u03bcIU\/mL, a range associated with stronger metabolic health, better weight stability, and sharper cognitive performance over time.<\/p>\n
5. GGT: A small enzyme with big longevity clues <\/p>\n
Gamma-Glutamyl Transferase (GGT) is a liver enzyme that quietly reflects oxidative stress and detoxification capacity, two underappreciated drivers of aging.<\/p>\n
Although often overlooked in routine checkups, elevated GGT is linked to faster biological aging and higher mortality risk.<\/p>\n
Vass recommends keeping GGT between 10 and 25 U\/L. He explains that it \u201cpredicts oxidative stress and mortality risk \u2013 quietly tracking both liver health and the hidden oxidative processes that drive aging.\u201d<\/p>\n
A roadmap for longer, better living <\/p>\n
Together, these five biomarkers form a roadmap, not only for predicting lifespan, but for improving it. They offer a rare glimpse into the body\u2019s cellular tempo: how it ages, adapts, and responds to stress long before diseases develop. For Vass, knowledge is something we should leverage.<\/p>\n
\u201cWhen you know these numbers, you have a roadmap to reverse early decline and add healthy years to your life,\u201d he emphasized. \u201cThis is what true preventative medicine looks like.\u201d<\/p>\n
In a world overflowing with longevity hacks, it turns out the most reliable clues are hiding in plain sight \u2013 written not in the stars, but in your blood.<\/p>\n
