5 /5 Jordan Knight: Dr. Gundry has been treating me and my entire family for over a decade. He has made us all healthier and I would put money on it that he is also adding decades to our lives! Yes, he does sell a lot of supplements- but honestly he makes good products. He provides so much information for free, he deserves to make a buck! This man is an encyclopedia and continues to learn and research to this day.
