Please read this quote from the patient handbook by Dr. Schulze the originator of the IF #1 and #2. (especially second sentence)
>>>Start with only one capsule of this formula during or just after dinner. This Formula works best when taken with food, The next morning you should notice an increase in your bowel action and in the amount of fecal matter that you eliminate. The consistency should also be softer. If you do not notice any difference in your bowel behavior today or the difference wasn't dramatic, then tonight increase your dosage to two capsules. You can continue to increase your dosage every evening by one capsule until you notice a dramatic difference in the way your bowel works. There is no limit. Most people need only 2-3 capsules but a few have needed over 30 capsules. It has taken most of us years to create a sluggish bowel, so let us be patient for a few days and increase by one capsule each day only.
This formula can be taken for a week, a month or the rest of your life. Continue to use this formula until you are having one bowel movement each day for every meal you eat, between. 2 and 4 bowel movements a day are normal. Considering all the disease and death we have because of retained fecal matter, I wouldn't worry about taking too much of this formula. Dr. Schulze ICF #1
