Probiotics are the bacteria inside our intestines that promote digestion. Examples of probiotics are Lactobacillus, Bifidobacterium, and Sacchromyces boulardi, and they are available in supplement form and some foods, such as yogurt. Some studies have shown that probiotics are an effective non-drug cure for constipation. Like fiber, probiotics are a relatively easy home cure for constipation because they are available in foods that many families already have in the refrigerator.
However, the jury is still out on probiotics for constipation. Recently, Polish researchers conducted a systematic review of trials on the effect of probiotics on constipation and concluded that there was not yet strong enough evidence to support their recommendation.
