🚨 Biological Age scores: buyer beware 🚨 After multiple tests with Function Health, my husband and I saw our “Biological Age” jump 10–30 years — despite only minor, clinically insignificant changes in actual lab markers. When we asked how this was calculated, Function confirmed: • The score is automatic and not reviewable • No member-level breakdown is available • No clinician or data scientist can explain individual results • The only explanation is “it’s based on an NIH study” To be clear: the science exists. The transparency doesn’t. If a health metric: • Can swing by decades • Can’t be reconciled with your labs • Can’t be explained when it looks wrong …it’s not actionable for consumers. My takeaway (opinion): treat “Biological Age” as a wellness/engagement score, not a precise measure of your health. Focus on real biomarkers. Numbers you can’t audit aren’t insight — they’re noise. (Sharing my experience so others can decide for themselves.)

Upsell nightmare and terrible delays. When I reached out to check why the delays existed the reply was "have you completed the exams?" Which I found it outrageous since this should be all automated.

This Company pitched the importance of good health based on a full 100 point blood scan. Reasonably priced at just under $400. Not a big deal when you read the results. I resolved to do it every two years. Then they billed me for a second round 11 months later WITHOUT ADVISING ME OF THE RENEWAL So I get waylaid after the fact with AN UNETHICAL BILLING. And their principal is one of these gadabout talk show white knights that brags on his personal concern for all of us individually. YEA RIGHT! ______________________________________________ they did process a refund, but I was never given advance notice of any kind, and more and more that seems to be the prevailing attitude. Why would I have posted my outrage had I been given advance notice?

I’m very unhappy with the turnaround time for my very simple labs. I received results for the same test the very next day from a different Discount lab company and my labs are still held hostage by Function health. After multiple requests.

Product is okay but has super shady business practices. You have to fill out this long form to cancel. They send no confirmation, so you have no receipts. I first canceled months ago and received a full refund. Then they rebilled a few months later. I flagged it the same day, and the billing is refusing to refund me. It's completely mad, but what can you expect from a soulless VC-backed data harvesting med tech companies?

I hate services like this. They make it super easy to signup but make you jump through hoops to cancel. I recenlt purchase a subscription have reading through all the testing the service offers. However, many of the test do not come with the subscription and are offered at addtional cost. This is understandable, but they do not make that clear on the main page. After realizing this 10 minutes after signing up, i decided to cancel. This is where the it gets infuriating and they make you jump through hoops. The only way to cancel it to go through their stupid chatbot or wait days for your email to be answered by a representative. Then they make you answer a long questionaire of why you want to quit the service and force you to look through additional offers. Even after all of the crap and contacting support a number of times,7 days later I still haven't gotten a confirmation of my cancellation or refund. Don't use this service!!!!!

system was down. drove 90 miles for nothing. Is there not a way you could notify patieces about clithes in the system, which are understandable. But the system was down at 8_00 and my appointment was at 10. I could have been notified.

Super disappointed. I left Lifeforce for Function because it was supported by Huberman. It might be that once you get into the platform it's good, but I have had multiple conversations with their terrible support team simply to get the login to work and still can't work it out. In the middle of a chat session the chat tool quit working. The basic experience is terrible so I can't imagine they are going to get the hard stuff right.
