Your Optimal Zones...New and Improved

By Gil Blander, PhD Feb 05, 2014

 

My lifetime goal is to help humankind to live longer, delay the onset of age-related disease, and improve quality of life. Very early in my professional career, I learned that to do that we need to know what is happening inside our bodies. The best indicator for that is blood analysis, as it reflects the current status of our organs and body systems.image

 

1)   They are most relevant for a healthy person looking to improve his or her health and performance;

2)   A high percentage of the healthy population is not optimized: I was not looking for markers where just one out of one million people is optimized; and

3)   They are actionable: marker levels can be modulated by food, supplements, exercise, and lifestyle changes.

My next task was to develop an optimal zone for each of these 30 biomarkers. The rationale was simple: before InsideTracker, all of us had the same normal zone for specific markers, regardless of if you were male or female, old or young, white or African American, athletic/active or a couch potato, or a heavy drinker or sober. We developed the optimal zone by extracting relevant information from peer-reviewed scientific publications about specific populations in relationship to specific markers. For example, the normal zone for ferritin for females is above 12, but young athletic females might need more iron due to monthly iron loss with the menstrual cycle, or exercise that depletes iron levels. That is why the optimal zone for ferritin for such a person is much higher than 12. The second method of developing the optimal zones was by using a large database of hundreds of thousands of data points from the American population that includes all of the demographic information (age, gender, ethnicity, athletic activity, and so on) connected to those biomarkers. That mega-database allowed us to find the zone in which the majority of your peers’ levels fall, and then based on that, create and draw the optimal zone for you. We use a mix of these two methods to calculate the optimal zone for each of our customers.

Recently, you may have logged into your InsideTracker account and noticed your personalized optimal zones are different. The reason your optimal zones have changed is that last year, we decided that we needed to re-evaluate the validity of each marker’s optimal zone in order to provide our customers with the most innovative information possible. To do that, we significantly expanded the size of the population database and in addition, we reviewed all of the rules extracted from the peer-reviewed scientific publications and updated them based on newer, more cutting-edge research. One area we specifically focused on was the impact of specific markers on the aging process and how that affects the optimal level for a specific customer (unique age, gender, ethnicity, athletic activity, and so on). Our goal is to provide personalized, powerful, and practical information to each customer, allowing you to live longer and delay the onset of age-related disease.

InsideTracker helps you maintain and kick up a notch your health and performance by defining your personalized optimal zones for a specific, relevant set of blood biomarkers. We still provide this service, but now, your zones are updated and even more relevant and accurate than before. The simple and natural recommendations we prescribe to you to bring your out-of-the-optimal-zone biomarkers in to your unique optimal zone are therefore also now even more valuable.
