Probiotics May Be Equally Effective in Any Form

Probiotics come in a variety of forms, from powders and capsules to foods such as yogurt, dairy drinks, infant formulas, cheese, and even snack bars that are supplemented with specific probiotic organisms. Any of these forms may be effective for some digestive problems as long as they contain the beneficial organisms in adequate numbers.

“Some people prefer to take probiotics in the form of food. Others prefer taking a capsule or powder,” says Stefano Guandalini, MD, a professor of gastroenterology at the University of Chicago School of Medicine. “It’s really a matter of personal preference.”

Probiotic supplements should be taken according to label directions, under the guidance of your doctor. Your doctor can advise you about which probiotics foods or supplements may help you and how often and how long you should use them.

Choose the Right Microbes for Your Needs

More important than the form of the probiotic product you use are the particular microbes that it contains. “Many different potentially useful probiotic organisms exist, including both bacteria and yeast,” says Martin Floch, MD, a leading gastroenterologist at Yale University, author of Probiotics: A Clinical Guide, and a consultant for the Dannon Company. “Their effects are very specific. Certain strains appear to be helpful only for certain conditions.”

The strains that appear to be most effective in treating infectious diarrhea, for instance, include Lactobacillus GG and Saccharomyces boulardii.

Probiotics Won’t Help All GI Problems

Convincing evidence shows that probiotics can speed recovery from infectious diarrhea. They may also ease symptoms of irritable bowel syndrome. But probiotics may not offer much benefit for people with Crohns disease. There is benefit in preventing remission of pouchitis, but other areas are not conclusive.

For some conditions, even the experts disagree about whether or not probiotics help.
