How does InsideTracker determine optimized zones?Updated a year ago

When you get blood lab results from your doctor, you typically see how your levels compare to the “normal range” compared to the population average for that marker. InsideTracker’s optimal zones go beyond this and personalize a range just for you. 


Instead of just telling you whether you fall within the normal range for these markers, InsideTracker gives you a more precise range called the “optimal zone.” Differences in individuals’ optimized zones don’t end with age. They also vary based on sex, race, habits, and even athletic activity.


For example, the normal range for a woman’s ferritin level is between 12-150 ng/dL. But InsideTracker recommends that an active woman in her 20s should have blood levels of ferritin between 40-150 ng/dL for peak endurance performance. 


If your biomarker levels do not fall within your personalized optimal zone, InsideTracker’s algorithm recommends effective yet simple interventions including diet, supplements, and training modifications to improve your unoptimized biomarkers. 


To properly understand how all of these factors impact biomarkers, InsideTracker is constantly extracting information from peer-reviewed research on these relationships, and using it to create personalized "optimal zones." Therefore, as new research is published, you may see your optimal zones adjust accordingly. Read more about InsideTracker’s optimal zones in these two blogs.
