I have over my 53 years received many treatments with antibiotics for one thing or another. Since the age of 31, I have suffered the most uncomfortable GI tract disturbances that I don't care to describe. I was actually reaching the point in my life where I did not want to live anymore. Within the last month, I was fortunate to come in contact with a doctor who introduced me to Primal Defense. Rather discouraged and having spent a considerable amount of money on products to assist my GI system to function like it used to, I desperately committed myself to trying PD. To my utter surprise, it is working for me. After taking PD for less then one week, my GI tract is functioning normally!! I have been taking PD for over one month now and I am amazed with how great I am feeling now. I thank you so much for this product. You have no idea how grateful I truly am towards you and the doctor who was so kind to expose me to your product. Comfortable at last after all these years!!!!!!!
