People should do labs with function health very easy and explains everything a lot instead of regular dealing with crazy insurance

What a great understanding of what's going on with my physiology. A great price too, literally a few dollars per biological data point!!! After 2 years of dealing with Long COVID this Function Health test gave me solid foundational understanding of my health - finally some hard data. I couldn't get my Doctor to do any testing other than what the insurance company allowed, the $499 investment was the best money I've spent!!!! The analysis, feedback and corrective action was better information and advice than I ever received from traditional western medicine - I highly recommend it

They lay it out so it is easily understood. They give diets and supplement information.

I've been going to Naturopathic Doctors since 2010. Each time it's a different lab with paper print outs. In the past few years, I even created a Spreadsheet to track that data from year to year. I discovered Function Health in 2024 and it's been a game changer. All my results in one place and even more data than what the doctors intially order. I feel so much more knowledgeable about my results and can always go back to review. I'm a customer for life!

The reminders prior to the visits along with step by step instructions on how to check-in! I loved having the summary for the results, which made it very easy to read. The ability to also share the results via PDF with my doctors was fantastic!

The information that I received from function health was invaluable. From the blood results spanning a whole wide range of things, to the doctors notes and the advice on what to eat and what to avoid and what supplements to take and what to avoid. I am very grateful. Thank you.
