Biological Age Calculator
Estimate your biological age using the PhenoAge algorithm.
Understanding the Biomarkers
This calculator uses several key biomarkers that are strongly associated with aging and overall health. Here's a brief overview of two of the most important ones:
Creatinine (mg/dL)
Creatinine is a waste product from muscle metabolism. Healthy kidneys filter it out of the blood. While levels vary based on muscle mass and diet, a lower creatinine level within the normal range is generally associated with better kidney function and overall health. In the context of aging, maintaining kidney function is crucial, and elevated creatinine can be an early indicator of decline.
Albumin (g/dL)
Albumin is the most abundant protein in your blood plasma, produced by the liver. It's essential for maintaining osmotic pressure and transporting hormones, vitamins, and enzymes. Higher albumin levels are a marker of good liver function, nutritional status, and low inflammation. As we age, albumin levels can decline, making it a powerful predictor of health outcomes and longevity.
Case Studies: Age is Just a Number... or is it?
The Optimized Biohacker
A 45-year-old with excellent biomarkers: low inflammation (CRP), optimal albumin, and great kidney function (creatinine).
Bio Age: 38.2
The Average 45-Year-Old
A 45-year-old with typical, slightly suboptimal biomarkers that fall within the standard lab ranges.
Bio Age: 47.5
The Unhealthy 45-Year-Old
A 45-year-old with high inflammation (CRP > 3.0) and other poor markers, indicating accelerated aging.
Bio Age: 55.1
