LDH: The cell damage enzyme that reveals how fast you're aging
Lactate dehydrogenase (LDH) is an underrated biomarker. Discover why elevated levels indicate tissue damage, accelerated aging, and what you can do to optimize them.
Urea and BUN: Your kidneys as a mirror of health (and longevity)
Blood Urea Nitrogen (BUN) is an often-overlooked kidney biomarker. Discover why blood urea predicts aging, what the optimal values are, and 6 strategies to protect yourself.
NLR: The neutrophil-to-lymphocyte ratio hidden in your CBC that predicts longevity
The neutrophil-to-lymphocyte ratio (NLR) is a powerful biomarker of chronic inflammation and aging. Discover optimal values, what it reveals, and how to improve it.
ApoB: The real enemy of your arteries (and why LDL cholesterol isn't enough)
Apolipoprotein B is one of the clearest markers of atherogenic particle burden. Learn what ApoB is, when it beats LDL cholesterol, risk-based targets, and how to lower it.
DHEA-S: The youth hormone that declines with age (and how to slow it down)
DHEA-S declines with age, but it is not a proven anti-aging target. Learn how to interpret levels, cortisol balance, lifestyle levers, and supplement risks.
GGT: the liver marker linked with longevity and mortality risk
GGT is more than a liver enzyme. Learn how it relates to mortality risk, oxidative stress, fatty liver, and practical ways to improve trends.
Lp(a): The genetic cardiovascular marker you need to know about
Lipoprotein(a) is the most underestimated inherited cardiovascular risk factor. Learn what Lp(a) is, optimal levels, how it differs from LDL and ApoB, and how to protect your heart.
Alkaline phosphatase (ALP): Liver, bones, and the hidden link to longevity
Alkaline phosphatase (ALP) links liver, bone, inflammation, and biological aging. Learn high vs low patterns, practical tracking zones, and when to follow up.
Creatinine: What your kidneys can reveal about longevity
Creatinine links kidney filtration, muscle mass, and biological age. Learn how to read eGFR, cystatin C, UACR, trends, and longevity context.
