Yes, the Schulze formula#2 contains both and is also soothing to the digestive tract. Are you doing a grain free diet? I ask because as compromising as grains can be for those of us with candida, they also are excellent for absorbing intestinal toxins. If you aren't doing brown rice, Perhaps some quinoa amaranth or millet? Maybe just until you recover fully.
I would take them until you feel sufficiently better. And also adding some essential fatty acids. Your system is burdened not just by the flush but by the release of toxins and you need to make sure you are adequately recovering.
Your vegan diet sounds excellent for the week prior to a flush, however in the time between you should eat healthy fats, to keep your bile flowing.
