What is mitochondrial health, really? This guide explains mitochondrial activity, ATP production, oxidative stress, and the connection between mitochondrial dysfunction and cellular senescence—plus which biomarkers and Biostarks tests can help you assess the surrounding biology.

Metabolic health is more than blood sugar. This introduction explains why HbA1c, lipid profiles, ApoB, Lp(a), creatinine, and related biomarkers form the foundation of cardiometabolic screening, risk prediction, and even many biological age algorithms.

Homocysteine is one of the most useful functional biomarkers in methylation biology, but it is often oversimplified. This deep-dive explains what homocysteine measures, what can raise it, which adjacent biomarkers matter most, and how to interpret it with more nuance.

A practical, science-based guide to insulin resistance: what it is, how it develops, which early signs matter, and the key biomarkers to track over time before overt diabetes appears.

How often should you retest biomarkers? This practical guide explains when to repeat nutrition, metabolic, and longevity markers based on biological turnover, intervention timing, and real-world decision making.

Methylation is a core biochemical process linking folate, vitamin B12, homocysteine, and gene regulation. This article explains how one-carbon metabolism works, which biomarkers matter most, and how to interpret methylation biology with more nuance and less hype.

Urolithin A is a gut microbiome-derived metabolite linked to ellagitannin-rich foods, mitochondrial health, and mitophagy. This deep dive explains what it is, how it is measured, what the human evidence actually shows, and why interpretation requires biological context.

What is oxidative stress, really? This introduction explains redox balance, reactive oxygen species, lipid peroxidation, and why biomarkers such as 8-iso-PGF2α help make oxidative stress measurable rather than vague.

Mass spectrometry is a gold-standard technology for identifying and quantifying molecules with extreme precision — powering anti-doping labs, pharma analytics, and modern metabolomics. Here’s how GC-MS, LC-MS, and ICP-MS differ, and why Biostarks uses mass spec on dried blood spots (DBS) to quantify large biomarker panels from a simple finger prick.

TRT isn’t just about raising testosterone — it’s a system-level intervention that affects hormones, blood markers, and cardiometabolic risk. Here’s what TRT is, which biomarkers matter most (beyond total T), and how Biostarks helps you monitor results responsibly.

EPA and DHA are the most important omega-3s for heart, brain, and inflammation biology—but testing can be confusing (Omega-3 Index vs plasma). Learn how to interpret low vs borderline results, the best food sources, smart supplement strategy, and what to measure next.

GLP-1 reduces appetite and improves metabolic health—but it can also shift hydration, recovery, and nutrient intake when food volume drops. Companion biomarker testing helps you track the right signals and personalize your plan for safer, more sustainable results.

Ferritin is your body’s iron storage marker—and one of the most actionable tests for fatigue, performance, and long-term health. Learn how to interpret low, borderline, and high ferritin (including inflammation effects), the best iron-rich foods and absorption tips, and which labs to check next.

NAD⁺ is a core “cellular energy + repair” molecule—and one of the most misunderstood longevity biomarkers. Learn what NAD⁺ measures, why results vary by method, how to interpret low vs borderline levels, and the smartest next steps (lifestyle, trend tracking, and precursors like NR/NMN).

Inflammation isn’t the enemy — it’s your immune system doing its job. The real risk starts when inflammation fails to resolve and becomes chronic, silently increasing cardio-metabolic and recovery burden. In this deep dive, we break down acute vs chronic inflammation, then map the key biomarkers that reveal what kind of inflammatory physiology you’re dealing with: hs-CRP, ferritin, uric acid, cortisol, and 8-iso-PGF2α (oxidative stress). We also explain why omega-3s (EPA & DHA) are less about “blocking inflammation” and more about supporting resolution biology through specialized pro-resolving mediators — and how to use trends, not one-off results, to track progress.

Testosterone is easy to misread: timing, SHBG, and “free vs total” change everything. Learn how to interpret low or borderline results, what to retest next, and the most common root causes.

Magnesium powers energy, muscles, nerves, and recovery—but the common blood test can miss early depletion. Learn how to interpret low vs borderline results, what to check next, and how to fix it with food and smart supplementation.

Longevity starts with measurement. Discover key biomarkers—like NAD+ and essential micronutrients—that reflect cellular energy, resilience, and healthy aging.

Home blood tests and lab visits can both deliver reliable biomarker data. The best choice depends on your goals, convenience, and tracking needs.

A biomarker test measures objective signals in your blood to reveal cellular function, energy, and resilience—helping you make data-driven health decisions.

NAD+ is essential for cellular energy production, DNA repair, and longevity. Learn why declining NAD+ levels matter and how measurement supports long-term health.

Biostarks is partnering with Welldium to bring advanced at-home biomarker testing to healthcare practitioners across Europe—unlocking more personalized, data-driven wellness pathways.

Active B12 (holoTC) shows how much vitamin B12 is truly available to your cells. Learn how to interpret it with MMA/homocysteine and act.
