Biological Age Calculator
Your Estimated Biological Age
Based on lifestyle markers relative to your chronological age.
Your birth certificate tells you your chronological age, but biological age measures how your body has aged at a cellular level. Two people can both be 45, but one may have the vitality of a 35-year-old. This "Aging Gap" is often driven by lifestyle choices, sleep, and stress.
Unlike your Chronological Age, your biological age is plastic—it can be lowered! This tool uses health markers to see if you are biologically closer to a different Generation. Use it as a baseline to optimize your health before you reach Retirement.
