I learned through my participation with Function that I have CLL. I am now under the care of MD Anderson Cancer Center for my form of Leukemia.

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!

With my test results, I was able to identify several markers in need of improvement. With addition of many of the supplements listed, I was able to reduce my mercury from 25 to 16 in less than 2 months. I was able to order the mercury test individually for a very reasonable price, which allowed me to monitor the efforts I have been putting in to reduce that marker.

Finding and using Function Health may have been life saving. I had no idea, but I may be dealing with a serious cardiovascular concern that's related to my family history. I thought I was healthy and fit and didn't have to worry. I'm really glad I did this and now have the opportunity to make changes before it's too late. Thank you!

Based on my cardiovascular history, I found very useful to know how my body is improving on the ApoB and LDL biomarkers, as well as my biological age: from -13 years to -15 years, based on the Action Plan you recommended.

Thank you for all you are doing for chronically ill patients like me! This has already saved me thousands of dollars in lab costs. My other medical dr bills, meds & tests are already at $4,000 towards our deductible so this savings is a big help!

Thank you so much for all the work you put into this company. I wish I had this years ago when I was struggling with conventional medical practitioners. I believe this company is the future! Much love to your team.

Function detailed labs provide valuable information that allows me to control my health. It will be valuable to have insight on how to make lifestyle changes that would help correct the areas that need improvement.

I am so impressed. I texted on a holiday Sunday about my period starting/rescheduling bloodwork and I got an answer within 5 minutes. Plus help scheduling. I’m impressed with the lab info so far. I really love this more than I thought I would.

I appreciate the detailed feedback regarding the test results... food, supplements, causes and whys. It makes understanding my health and making smart choices easier. - Mother of 4 in Kansas
