What’s possible when you own your health? Our members say it best.
Function gives me the view and accountability into the things that need improvement and the things that need work. This is a new standard of care as health is more than just the absence of disease. This is easily the best healthcare purchase I've made in the last 20 years.
Function is a blessing to my life. If I had Function earlier in my life, I would not have struggled with PCOS, IBS, and food sensitivities for as long as I did. I am SO excited to have this moving forward. I feel relieved, empowered, and inspired. Thank you Function team!
Real people. Real results.




As someone navigating an autoimmune condition, it's been such a relief to finally have a clear, visual way to track what’s going on in my body—and actually understand it.

Early detection has given me this amazing gift of extra years, probably extra decades, with my family.

After 10 years of dealing with a health issue, 5 years of trying to get doctors to run more in-depth tests, Function finally helped me uncover the root cause.
