Frequently Asked Questions About VSL#3®

VSL#3® for Irritable Bowel Syndrome (IBS)

What is a probiotic and how can it help me?

Your digestive tract contains trillions of bacteria. Most bacteria are considered good bacteria—the kind that keep you healthy.

But you also have bad bacteria. People with conditions such as IBS have more bad bacteria than good bacteria in their digestive tract. More bad bacteria can cause problems that lead to uncomfortable and even debilitating symptoms, as well as anxiety that comes from having to cope with those symptoms.

VSL#3® is an advanced probiotic option that provides multiple strains of bacteria needed to restore the necessary amount of good bacteria in your digestive tract to manage your condition.

What should I look for when choosing a probiotic?

Different probiotics provide different types or strains of good bacteria in different amounts. The number of good bacteria is measured in colony-forming units (CFU). Studies have shown that greater diversity of bacteria may provide better results than just 1 strain of bacteria. Studies have also shown that bacteria need to remain alive in the digestive tract in high amounts to have a positive impact. When choosing a probiotic, you should consider both the number of different strains and the total CFU count, which is usually measured in billions.
