What max are yout talking about? I think Dr. Sculze just says to take as many as you need, increasing by only one a day, until you are sucessfully having 1-3 bowel movements. I think the guy who had to take 50 was a very exceptional case that he mentions in his patient handbook
But I agree with you as to their safety and afficacy. I take them all the time and love them! Even when I was first taking them, it only took me maybe 4 pills before stuff started really...er...happening!
