Very satisfied with Function! And the team is beyond helpful. Will keep using this and refer to my people. Also, booked my mom for her bloodwork! Thank you, Function!

I have been able to learn so much through the detailed labs especially for something like leptin which no one has ever tested. Now in year two of my membership with 2.5 year improvement in my biological age I’m fine tuning my health as well as encouraging my family and friends and other connections to take charge of their own health by signing up. The new AI chat is superb. I’ve been able to connect some dots that I’ve never connected.

Very good value. The blood test suite would hav cost far more, and the in/range-out of range indications are very useful. However; the website does not make it easy to print out the results or download them in a useful manner.

Incredible program. Not only getting valuable lab information to understand my labs but now able to utilize the chat to gain insights and best practices to make important changes that can affect my health with a more positive trend. Worth every penny spent.

Appreciate you sharing this, Vicki. Your experience shows what’s possible when you have access to clear health data and a plan to act.
Brandy
I prefer function over super power because the results are easy to read and more bio markers are tested twice a year opposed to once a year.
