Inside Tracker sells blood panels for example, 20 things measured in your blood (e.g., hemoglobin, magnesium, Vitamin D). It was founded in 2009 in Boston, Mass., by Gil Blander, a biology Ph.D., and two other people. They started offering the service in late 2011. Their main customers are athletes (20% professional, 30% amateur) and many Quantified Selfer’s (20%). I recently interviewed Dr. Blander:
What have you learned from the data you’ve collected?
Around 60% of the population has low Vitamin D.[What's low Vitamin D?] As of today, if you look at the ranges of the diagnostic companies, they are saying that everything below 30 ng/ml is low Vitamin D. We are giving you your optimal zone based on age, gender, athletic activity and ethnicity. We also compare you to your peers.
