Comparison · InsideTracker
InsideTracker's recommendations come from an algorithm with a nutrition and lifestyle lens: concrete next-step lists for diet, supplements and training load, with well-curated science behind the nutrition. That algorithm is tuned for nutrition. Merlin reads the same results the way a functional and integrative medicine clinician would, and reads more than blood: genetics, imaging, body composition, gut, fertility. The voice is closer to a clinician than a nutrition coach.

Anyone with panels they haven't been able to make sense of.
A read, not a panel. Merlin reads whatever you already have - no required panel purchase - the way a functional and integrative medicine clinician would: cross-system reads across blood, imaging, genetics, body composition, gut, musculoskeletal, fertility and neuropsychiatric. Practitioner-friendly. The art-gallery model: the kind that keeps its doors open by keeping them low-cost. Your first month is $35 and reads your results together.

Prices are each platform's own public price, checked in September 2026. Each platform's product evolves rapidly; if anything here is out of date, the underlying structural distinction (cross-source synthesis, surface breadth beyond blood) still holds.
InsideTracker uses an algorithm tuned for nutrition. Merlin reads the way a functional and integrative medicine clinician would. The synthesis covers more than blood - genetics, imaging, body composition, gut, fertility - and the voice is closer to a clinician than a nutrition coach.
None of these platforms are either-or with Merlin: the synthesis layer reads whatever panels you already have, no matter who ran them.
A real Cardiovascular surface from a real anonymized panel: a score, a narrative in plain language, 19 biomarkers read in context, a plan, the follow-up testing worth running, and the questions to ask your physician. Every system you have data for gets this depth.
Bring what you have, wherever it came from - PDFs, portal downloads, a photo of a printout. Your first month reads your results together, across every system, then shows you what they mean and what's worth finding out next. If there's a lot, Merlin tells you what order to bring it in.
If you don't feel the value of Merlin after paying for your first month, tell us and we'll refund you in full. Monthly Core, once per person, by email within 30 days. The terms
