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.
Magnesium and longevity: The mineral 31% of people get too little of (and why aging research cares)
31% of the global population and 48% of Americans get too little magnesium from food and beverages. Learn how magnesium connects to telomeres, mitochondria, DNA repair, inflammation, dosing, food sources, and testing.
Omega-3 and biological aging: The nutrient that slows your cellular clocks by nearly 4 months
A 2025 DO-HEALTH analysis found that 1g of omega-3 daily modestly slowed several epigenetic aging clocks. Discover the 6 anti-aging mechanisms of omega-3s, practical dosages, best food sources, and the evidence-based stack with vitamin D and exercise.
Taurine and aging: What the science really says (after the 2025 NIH reversal)
The 2023 Science study suggested taurine could reverse aging — but a 2025 NIH study found taurine levels actually rise with age in humans. Here's what the evidence really supports for heart health, sleep, and longevity.
Vitamin K2 and biological aging: What the evidence says about arteries, bones, and longevity
The Rotterdam Study linked higher vitamin K2 intake with lower coronary mortality, and a 2026 randomized trial found slower CAC progression with MK-7. Here is what K2 can and cannot prove for artery, bone, and longevity health.
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.
Fasting insulin: the early metabolic signal your glucose can miss
Fasting insulin can reveal early insulin resistance before glucose rises. Learn useful ranges, HOMA-IR context, and safer ways to improve your metabolic trend.
