The massive number of tests is great and the explanation is detailed, however, not every human is healthcare savvy on all topics. Being able to talk to a licensed professional would help traction.

Very easy to navigate appointments. Test results took some time but easy to understand results and tips to help

It was interesting to see the results. However, I was expecting more of a one on one conversation regarding the results. It seemed to be essentially an AI report. Overall, I don't think I'd recommend it unless you have concerns and want a basic health check.

I love the comprehensive lab work! I felt like I was getting a complete look at my overall health, which felt empowering. I also loved the food and supplement recommendations. The only knock on the service was the clinician notes, they felt very general and AI generated to me, not very helpful at all.

Easy to schedule appointments, feel cost is reasonable, test locations close to home. Reports through. Only negative is doctor summary not a downloadable doc. Proactive testing gives me peace of mind and in gathering info I can make better proactive decisions on managing my health care.

Having the numbers matters. I love being able to get the data needed and having options for diving deeper into a variety of areas where warranted. This all helps me direct my health journey and supports my knowledge when interacting with various healthcare providers along the way.

Function Health is a game changer! I've tried multiple elimination diets. Until Function Health, though, I never thought to eliminate seven specific foods at the same time. Eureka! That was the secret that had eluded me. I'm so grateful. I've now hooked my family on the benefits, and they are going all out on Function Health.

Makes cancellation difficult, and purposely deceptive. There is no reminder that you are about to be charged $500 for an AUTOMATIC renewal. The cancellation should be a simple 1 button click option, yet Function Health makes it where you have to talk to a bot and wait 5 business days for a human to review! I don't even know if they will refund the hidden renewal charge. These are not ethical business practices. Do better Function!!
