Reviewers often highlight fast, solutions-focused customer support and clear, science-based biomarker reports. Many mention practical recommendations that helped with training, recovery, or everyday health tracking. A smaller group describes major issues with billing, account changes, and trouble stopping unwanted emails. Some also ran into app glitches and confusing interface behavior during uploads or regular use.
Examples from available reviews (Dec 2021 – Mar 2026).
Support was very fast and helpful.
“Very fast and helpful!”
Science-backed insights clarified bodily performance and offered clear recommendations.
“InsideTracker gives me science-backed insights into my blood results”
Company allegedly refused data deletion requests and kept sending harassing emails.
“They will steal your data and won't suppress it”
App fails to open and displays a blank screen.
“App doesn’t open, just get blank screen.”
Reviewers say support responds quickly, stays flexible, and fixes issues like expired tests or lab-draw scheduling. Several name specific staff who sped up solutions and extended access. A minority report problems that didn’t get resolved, including denied prescriptions, extra charges, and refused refunds.
Many users accept the higher price for detailed, usable biomarker analysis and describe the data as invaluable for tracking progress. Some connect the insights directly to better training or recovery. A smaller group questions the price for what they expected and complains about paid tests expiring before they could use them.
Many describe an easy signup, quick turnaround on results, and reports that are simple to understand. Others mention buggy or confusing app behavior, uploads being changed by the system, and gaps in features such as food tracking. These interface and app issues show up less often, but they trigger strong negative reactions.
Reviewers point to science-backed analysis, clear biomarker explanations, and practical action plans. Several note that results are pulled together in a thorough, easy-to-follow way with specific recommendations. No comments criticize the science or question report accuracy.
Some reviewers describe ongoing marketing emails and say they couldn’t stop messages or delete personal data; one describes it as harassment. Others report quick, helpful replies when they reach out to support. Complaints about suppressing data and unwanted messages stand out as a key negative theme.
Reviews are sharply split between very positive experiences and clearly negative complaints. Many users report strong results, helpful support, and actionable reports. A smaller but vocal group raises billing disputes, account changes, communication breakdowns, and app usability problems.
For each review, the core experience based on original source reviews.
