I love function. It gives me the ability to monitor my bios twice a year and make adjustments with food first and supplements if needed. I’m able to stay on top of my health and basically functional!

Very quick and efficient process from start to finish; very informative and affordable if you're into longevity and monitoring an array of blood factors. The tests are affordable and the app has an integration with Claude and the Apple Health app, so you can do indepth analysis of the data. I highly recommend. I just wish that there was a Quest lab in the Ann Arbor area.

The analysis of my blood was complete in the extreme. When the work was done it asked for feedback. If I were not very focused on my health, I would never have submitted to it. So, when FH gave me a biological rating four years older than my chronological age I commented about it. I was told to make a suggestion. FH uses certain blood markers to determine biological age. There are many other factors that contribute to a person's biological age that FH ignores. Its chatbot admitted that. I think FH fails miserably in its definition and use of the term biological age.
