Constpation is not fun, a blocked bowel is unhealthful, causes many othe symptoms and diseases, When I found Dr. Schulze's formula # 1, I found a true friend for lief! If you want a trew cleaning, use the # 2 as well, I do a compleate clease every few months, and my skin has cleared up, I've lost weight, and just feal so much better!I've done other clenses, And Dr. Schulzes is the best!
