I think the company is doing a great job. I had some questions because a few of the test were not showing up and they were answered immediately

I would highly recommend Function for those who are overloaded with health information and in need of a clear path to wellness. I appreciate how my Function dashboard is geared toward my specific test results and personal goals not one size fits all health advice that we have heard 1000 times. I love the targeted food and supplement list but I really like the AI chat portion of the system. I can enter in specific meals or ingredients and see how they align with my goals based on my biomarkers. It also recommends better substitutions and improvements to recipes I put in. Using the Ai Chat for meal planning focused on my personal biomarkers has cleared away all the overabundance of fad diet and supplement confusion. Finally, I feel like I can see a systematic path to wellness.
