Plain-English deep dives on every major biomarker, risk calculation, and treatment — grounded in real, recent peer-reviewed research from Lipa's 1.6M+ and growing study corpus. Every claim cited. Every grade visible.
The inflammation marker your standard lipid panel doesn't capture. What 47 peer-reviewed studies actually show about hs-CRP and your cardiovascular risk.
Vitamin D is one of the most-supplemented and most-debated markers. What the research actually supports for cardiovascular, immune, and bone outcomes — and why the standard reference range may be too low.
Ferritin can be depleted long before hemoglobin drops. The research on iron deficiency without anemia — a common finding that's often overlooked in routine bloodwork.
TSH is the standard screening marker — but it can be normal while free T3 and free T4 tell a different story. The peer-reviewed case for measuring the full thyroid panel.
Chronic low-grade inflammation is linked to nearly every major disease of aging. What your inflammatory markers actually tell you, and what the intervention research shows.
If you've ever walked out of a doctor's office told you're "fine" while feeling anything but, this is for you. The gap between "normal" and "optimal" is real — and the research explains a lot.
Up to 50% of the population may be magnesium-deficient, yet serum magnesium is rarely tested. Why standard blood tests miss it and what the research says about RBC magnesium.
Liver enzymes are on every basic metabolic panel, but most people don't know what mild elevations mean. The research on ALT, AST, GGT patterns and what they signal beyond liver disease.
eGFR and creatinine are part of every standard blood panel, but subtle declines often go unnoticed. What the research says about early kidney function changes and the markers worth tracking.
B12 deficiency can cause fatigue, cognitive fog, and neuropathy — yet serum B12 alone often misses functional deficiency. Why MMA and homocysteine tell the real story.
Ferritin is more than an iron storage marker. It reflects inflammation, liver health, and metabolic status. What the research says about optimal ranges versus standard reference ranges.
The Omega-3 Index measures EPA and DHA in red blood cell membranes — a marker increasingly studied as a predictor of cardiovascular events. What the research actually supports.
Cortisol is the primary stress hormone, but a single blood draw rarely tells the full story. The research on diurnal patterns, cortisol awakening response, and what your levels mean in context.
Biological age algorithms use routine blood markers to estimate how fast your body is aging compared to your chronological age. The research behind KDM, PhenoAge, and what the numbers mean.
Fasting glucose is one of the most commonly tested markers — but "normal" doesn't always mean optimal. What the research says about glucose thresholds, variability, and early metabolic signals.
The CBC is the most ordered blood test in the world — and one of the least understood. What each line actually measures, why ratios matter, and the patterns worth knowing about.
Total cholesterol, LDL-C, HDL-C, triglycerides — and why this panel is both the most familiar and most misunderstood test in routine bloodwork. What the research actually says about each number.
Uric acid is typically associated with gout, but emerging research links elevated levels to cardiovascular risk, metabolic syndrome, and kidney disease. What your level actually means.
Elevated homocysteine is linked to cardiovascular risk, cognitive decline, and B-vitamin status — yet it's rarely included in routine panels. What the research says about testing and intervention.
DHEA-S is the most abundant circulating steroid hormone and declines steadily with age. What the research says about DHEA as a marker for adrenal function, stress, and aging.
Testosterone replacement therapy moves more than total T. Hematocrit, estradiol, SHBG, lipids, liver enzymes — what the research says about monitoring each one while on TRT.
Total T, free T, SHBG, and the difference between "normal" and optimal. What the research says about testosterone levels, testing methodology, and when the numbers actually matter.
FSH, estradiol, progesterone, and the hormone shifts that start years before menopause. The blood tests that track perimenopause and what the research says about interpreting fluctuating values.
Polycystic ovary syndrome affects up to 10% of women, yet diagnosis is often delayed. The blood markers that matter — androgens, insulin, SHBG, AMH — and how to interpret them.
Insulin resistance can develop years before glucose markers shift. Why fasting insulin and HbA1c together are the early-warning system most physicians don't routinely order.
Metabolic syndrome is diagnosed by five measurable criteria — waist circumference, triglycerides, HDL, blood pressure, and fasting glucose. What the research says about each threshold and why they matter together.
Semaglutide affects more than weight. The research on lean body mass loss, B12 deficiency, metabolic markers, and the blood tests worth tracking while on GLP-1 medications.
Tirzepatide is a dual GIP/GLP-1 receptor agonist with distinct metabolic effects. The blood markers worth tracking — HbA1c, lipids, liver enzymes, thyroid, and body composition changes.
Body Protective Compound 157 has been studied for tendon healing, gut barrier function, and inflammation. What the peer-reviewed research actually shows — and where it's still preliminary.
If you're using or considering BPC-157, here's what the research says about the biomarkers worth tracking — inflammatory markers, liver enzymes, and the safety profile from published studies.
A synthetic fragment of a natural protein with documented effects on cell migration and tissue repair in published research. Where the evidence is — and where it isn't.
What the research says about monitoring blood markers while using TB-500. Inflammatory markers, liver function, and the safety data from published thymosin beta-4 studies.
