Great detailed, helpful information! Nothing like I’d ever received from a doctor visit. I’m using the recommendations all the time - foods to enjoy / avoid, etc. Can’t wait to re-test to see any changes!

The Function health app work very well.. it scheduling for lab appts was easy and they sent multiple reminders. Viewing results was easy and so informative. I love that it explains why the test is relevant, and suggests foods and supplements that can help to achieve optimal results! I sent copies to all my doctors which was easy as well. Great customer service too. Highly recommend!
