The overall value of the laboratory tests, that are not normally ordered by your primary care physician, is incredible. I learned so much more about how these labs impact my health. There is so much more information and the clinical notes pull it all together. And it's an amazing economical value, too!

Enjoyed the detailed explanations of my tests, and what I could do from a lifestyle perspective to make myself healthier, as well as supplements that could move me towards optimal health.

Everything was outlined and explained well. Intuitive application and easy to use. A plethora of information well outlined so you don’t need a phd to understand the results or recommendations.

The scheduling process was very flexible, I had to reschedule several times and it was fairly easy to do so. I thought that someone would call me and discuss the results but I got a long report full of terms I don’t understand so that was disappointing and I feel like the point of having the tests done was not met.

It's great for finding out every bio marker in your body very informative but would have been nice to have someone to talk to and give better guidance for the money at 500 dollars

I bought function after hearing it plugged on the Huberman podcast I listen to, who promoted labs such as heavy metals and cancer biomarkers. Unfortunately, all of these labs are extra and if you want all of them that will cost you about an extra 3k in testing. The labs provided are all labs that are free with preventative labs with any health insurance plan. I tried to cancel after not completing any labs but was still charged a $133 enrollment fee, biggest load of bs I ever heard of. This product is in no way worth the money get individual ala carte labs from the testing companies they use for a 1/4 of the price if you want them. And as per their response yes they responded to me but still can't explain why it cost them $133 to add you to their system which should be completely automated and not cost them anything. They say it is for access to their platform but I never used the platform so again they are just using well known podcasters to toute their product and then swindling you out of $133 when you realize that nothing that is touted is actually included.
