Optimal AgingThe PhysioAge Composite index
The PhysioAge Composite index explains 84% of the differences in the aging process.
Working with a Stanford University biomathematician, the PhysioAge Systems analyzes relationships among various biomarkers to develop the formulas used to calculate the physiological ages of six important organ systems. The result is the development of the PhysioAge Composite, a weighted composite index of these six underlying ages. The PhysioAge Composite is able to explain 84% of the difference amongst individuals in the aging process. No other system comes close to this benchmark in measuring the physiological age of important organ systems.
