Not only do you get peace of mind, you get a comprehension explanation of why each lab is important and also how to make diet and lifestyle improvements. They give details on what supplements to get too. I’m 63 and my health means everything to me. I don’t have to ask doctors for tests they are reluctant to order. I just make an appointment and go at my convenience. Loving it!

Alethia
It was just ok. I won’t be doing this route again. Again, not much direction. Results come and have no idea if the range is functional or conventional, no doctor reviews them with the patient.
