Gave good insights about my health. But price can still be affordable. Also, very less locations in mississippi.
Response from Function HealthJul 9, 2026
We're glad the insights were valuable. We hear you on pricing and lab availability in Mississippi and will pass that feedback along to the team.

I was given such a thorough summary after all my blood work was done! It was very helpful that they worked with everything I uploaded to go along with my bloodwork. I appreciate all the hard work that was put in into my report!

My story is long, but in short I will focus on one item…I have spent many ways to lower my LDL cholesterol (overall cholesterol 259, LDL 149) with no avail (without meds). I eat whole foods, no ultra processed, I exercise 1.5 -2 hours a day, I am thin. My HDL is 88. I went vegan just to see if it was the saturated fats. Nope. Everyone kept saying it must be genetic. Then I found Dr. Hyman’s podcast where he mentioned Function Health and taking control of your health. I began listening to him and all of his guest about heart health. Within 6 months all my mid year cholesterol levels normal. I spent 30 years with high cholesterol. —Function Health tests give you a better understanding of your where to focus and access to tests that doctors refuse to order /understand. Knowledge is key and Function Health is a fabulous tool to begin that journey.

The initial blood test is very thorough and a great value for the money. The testing covers every organ in your body, therefore the results are very insightful and helpful. The results are detailed, yet easy to read and understand. The suggested supplement regime is very detailed, informative and guidance driven as well. I am very pleased with the service and highly recommend it to everyone as the tests provide more details and are more in-depth vs your typical blood tests performed with your GP.
