In 2025 wellness The industry is worth over $2 trillion, according to McKinsey & Companywith health, sleepnutrition, fitnesswith appearance and mindfulness fixed as its defining pillars. But the questions dominating the conversation are no longer just how to get healthy, but how to stay healthy for longer. as longevity is accelerating into one of the key trends of 2026, as is our desire to measure, monitor, and optimize every aspect of our health.
Please enter your biomarker. “The body’s measurable signs that provide information about how the body and its systems are functioning,” says Longevity Expert, HUM2N Clinic Dr. Mohamed Enayat. “These include molecules in your blood, hormones, inflammatory markers, fitness indicators, and even body composition and sleep quality.”
Blood pressure, heart rate, blood pressure, etc. are nothing new. vitamin D Levels are already familiar biomarkers that doctors test, as well as metrics provided by wearables and wearable devices. wellness technology However, the field of longevity medicine is rapidly expanding both the scale of what can be tracked and the sophistication of how it is interpreted. What is your teaching philosophy? “Rather than treating the disease after it occurs, it is about maximizing healthy lifespan,” says Dr. Enayat.
More than 100 biomarkers can now be measured through expert lifespan assessments collected through blood, urine, saliva, or stool samples, imaging tests, or performance tests. the aim, Doctor Mark Hyman, M.D. He explains that it is “early indication of changes in areas such as heart health, metabolism, inflammation, and hormonal balance, often before symptoms appear.” His experience was “transformative.” “For decades, I’ve seen patients who were told they were ‘normal’ even though they were clearly unwell. When I started looking more closely at biomarkers, I started seeing problems years before the disease showed up in the diagnosis code.”
One of the most important markers that has received attention is ApoB. “Rather than just looking at cholesterol, we are now focusing on ApoB, which represents the number of atherogenic particles that can damage arteries. Elevated ApoB is strongly associated with cardiovascular disease, the number one cause of death worldwide,” notes Dr. Enayat.
The other is hs-CRP (high-sensitivity C-reactive protein), a marker of systemic inflammation. “It is a central factor in many age-related diseases, including heart disease, cancer, and neurodegeneration. Lower hs-CRP is generally associated with improved long-term health,” he continues. Olga Donica, Longevity Director clinique la prairiealso highlights the value of IgG glycan testing. “Glycans are chains of sugar that attach to the surface of cells. One of the cells they attach to is immunoglobulin G (IgG), one of the most important antibodies we have. Glycan structure changes the function of IgG, and its profile can predict various health problems such as cardiometabolic disorders and autoimmune diseases,” she explains.
In addition to blood tests, both experts emphasize the importance of cardiopulmonary function tests, especially VO₂ max. “This is a good functional biomarker of longevity because it reflects how the heart, lungs, blood vessels, and muscles work together to supply and utilize oxygen,” Donica says. “It is more systemic than other biomarkers that reflect the status of a single body function or pathway, and there is strong evidence that: longitudinal study We show that good cardiorespiratory fitness is a strong predictor of longevity. ”
At its core, “biomarkers take health from guesswork to precision, and from reactive medicine to truly proactive care,” Hyman says. Because most are influenced by lifestyle, diet, and environment, data can inform deeply personalized interventions, from nutrition and training to advanced medical protocols. Dr. Enayat says, “Heredity influences guns, but lifestyle is often the trigger.”
“Successful use of biomarker testing can help make health capital more tangible and adjust longevity strategies based on real-world data,” adds Donica. As testing technology becomes more available and interpretation becomes more sophisticated, annual screening is increasingly encouraged.
“In my opinion, anyone concerned about their future health, not just those who are already unwell, should consider a thorough biomarker evaluation even earlier, starting in their mid-30s and with a strong family history of cardiovascular disease, diabetes, cancer, or autoimmune disease,” Dr. Enayat says. “If you wait for symptoms, it’s too late. Longevity medicine and biomarker testing aim to detect subtle changes long before you get sick.”
Still, the rise of health score culture poses important warnings. “Biomarkers are tools, not verdicts. Numbers should not scare people, they should empower them,” he reminds us. “No single biomarker tells the whole story. Longevity medicine is about putting patterns and puzzle pieces together to discover how multiple markers, genes, lifestyle, and lived experiences interact.”
So instead of chasing perfection, biomarkers are becoming one of the most powerful tools available to those looking for deeper insight into their bodies in order to manage their future health.
