I have been using Quantum Nutrition Labs products for many years and will continue to use their products. Gallbladder Support is my favorite of all of the products that I use even though they all work well for me. I'm 76 years old and several years ago I was having trouble eating certain foods so after listening to Dr. Bob one day I decided to try the Gallbladder Support. I don't remember how many years ago it was but I'll tell you if I don't take it I have trouble digesting many different foods and that's why I make sure that I take 1 each morning and it WORKS! I believe that I take at least 5 of their products daily and I always stock up and make sure I don't run out !
