My GI doctor also does not address SIFO. I have done curcumerin 300 to 500 mg orally twice daily for 4 weeks as outlined in Dr. William Davis' book Super Gut. Because you want the supplement to stay in the intestinal tract and NOT get absorbed, he recommends only certain brands for this purpose: NOW curcumerin softgels, Jarrow Formula curcumin 95, Life Extension curcumin Elite rxtracr, and Solaray curcumin. He also has other ideas in the book. I have seen some improvement when I have implemented his strategies, but I certainly do not agree with everything he says.
