The 9 Biomarkers That Power Your Biological Age
The validated Levine PhenoAge model synthesizes these nine specific routine blood markers to calculate your cellular wear-and-tear and actual physiological age.
1. Albumin
Liver & NutritionA primary protein synthesized by the liver. Optimal levels reflect strong liver function and sound nutritional status, whereas declining albumin is frequently associated with systemic inflammation or chronic stress states.
2. Creatinine
Renal HealthA natural metabolic waste product filtered out by your kidneys. It serves as a direct indicator of renal filtration efficiency and muscular integrity. Maintaining stable filtration is essential for long-term healthspan.
3. Fasting Glucose
MetabolicMeasures how well your body processes sugar after an overnight fast. Elevated fasting glucose points toward insulin resistance, which heavily accelerates cellular aging across major organ systems.
4. hs-CRP
InflammationThe gold-standard systemic marker for chronic inflammation. High levels act like cellular "rust," driving vascular wear, metabolic dysfunction, and cardiovascular risk long before physical symptoms surface.
5. Lymphocyte %
Immune StatusRepresents the proportion of white blood cells dedicated to adaptive immunity. Balanced percentages indicate a resilient immune system, while imbalances reveal underlying chronic stress or immune system fatigue.
6. Mean Cell Vol (MCV)
Cellular HealthEvaluates the average physical size of your red blood cells. Abnormal values often point toward underlying micronutrient deficiencies (such as B12 or iron) that impair cellular replication and oxygen delivery.
7. RDW
Systemic StressMeasures the variation in size among your red blood cells. Elevated RDW signals increased physiological stress, underlying inflammation, or impaired cell production, and correlates strongly with mortality risk.
8. White Blood Cells
Immune FunctionThe total count of your circulating immune cells. Mild, chronic elevations frequently signal low-grade immune activation and persistent systemic inflammation, which directly speeds up biological aging.
9. Alkaline Phosphatase
Liver & BoneAn essential enzyme linked heavily to liver and bone metabolism. Elevated ALP indicates hepatic stress or accelerated bone turnover, capturing broader shifts in metabolic vitality as we age.
The Systantra Advantage: Real-Time Tracking
While the 9 PhenoAge markers provide the ultimate baseline, they can be slow to move. To give you immediate, real-time feedback on your new diet and lifestyle protocols, the Systantra Engine tracks these advanced, highly sensitive markers alongside your Biological Age.
Fasting Insulin
Detects insulin resistance years before glucose levels become abnormal.
HOMA-IR
The clinical gold-standard calculation for deep metabolic health tracking.
ApoB
A highly precise marker for assessing true cardiovascular disease risk.
GGT
A sensitive liver enzyme that acts as an early warning for oxidative stress.
