InsideTracker analyzes your blood biomarkers and provides recommendations. Singular analyzes your biomarkers and delivers the formula, with bioactives selected to target the biological hallmarks of aging. That's the fundamental difference between these two services: one advises, the other produces. InsideTracker excels in data analysis. Singular integrates analysis and manufacturing into a complete longevity-oriented service.

InsideTracker provides a detailed dashboard with personalized recommendations: nutrition, exercise, sleep, and supplements. The quality of the analysis is well-regarded. But execution rests entirely on the user.
Singular analyzes biomarkers and manufactures the corresponding formula. The member directly receives their precision powder, ready to consume. No product research, no assembling separate supplements. What goes into the formula is validated by an independent scientific committee — experts in longevity medicine, clinical pharmacology, cellular biology, and functional nutrition. Every bioactive passes three filters: proven efficacy through meta-analyses or randomized controlled trials, documented superior bioavailability, and no functional redundancy. The scientific framework is built on the 12 hallmarks of cellular aging (López-Otín et al., Cell 2023). InsideTracker excels at data analysis; Singular translates that analytical rigor into a physical product formulated according to an explicit longevity framework.
The difference is measured in adherence rates. Receiving a list of recommendations and receiving the tailored formula do not produce the same level of compliance over time.
InsideTracker is based in Cambridge, Massachusetts. The full service — including blood draws at a partner laboratory — is available only in the United States.
International users can create an account and upload their blood results. But they do not have access to InsideTracker-organized blood draws or the full range of features.
Singular operates from France and delivers to Europe, the United Kingdom, Switzerland, and the United States. The blood test is organized at a partner laboratory near the member.
InsideTracker charges $149 per year for the dashboard subscription. Each blood analysis costs between $340 and $528 depending on the panel. With two panels per year, the total cost reaches $830 to $1,200. With four panels: $1,510 to $2,260. Recommended supplements are purchased separately.
Singular charges 349 € per month, all-inclusive: blood test, analysis, formulation, manufacturing, and delivery. Over 12 months: 4,188 €.
InsideTracker is cheaper if you only want the analysis. Singular costs more if you include the delivered formula. The relevant comparison adds the cost of separately purchased supplements to the InsideTracker price.
InsideTracker offers InnerAge, a biological age score calculated from blood biomarkers. This indicator synthesizes multiple parameters into a single number, which makes communication and motivation easier.
The methodology relies on statistical models linking certain biomarkers to aging. The indicator is useful as a longitudinal tracking tool — observing the trend over time — rather than as an absolute measurement.
Singular does not offer a biological age score. The approach prioritizes individual tracking of each biomarker with personalized optimal ranges, rather than a composite indicator.
