I know personnaly that I will have a horrible day while doing the diet and candida killing type supplements, and then the next day I will have candida in my stool. Going on about 6 yrs now of diet and supps!!! I know when it first started coming out , it was off white, light brownish and yellow. Now when it comes out, it is usually white. I heard the older it is the darker the color. I guess I have diet dicrepensies(sp) occasionally and the yeast regrows.
