Probiotics (healthy colon bacteria) can help restore normal bowel function. Excess antibiotics and sugar cause the overgrowth of yeast and unhealthy bacteria, and the healthy bacteria in the bowels are needed to keep them in check. Unfortunately, unless protected, over 99% of these bacteria are killed by stomach acid before they get to the bowels where they are needed. Because of this, you should take probiotics in a "pearl" form. Pearls do not dissolve in stomach acid, and keep the bacteria safe during their ride through your stomach (like troops in a tank). Once they hit the alkaline intestines, they dissolve and release the troops.
