One of the less common probiotic strains you may see in your multi-strain probiotic is Streptococcus salivarius thermophilus. Although most people are familiar with Strep bacteria as the ones that cause Strep throat, this particular strain is actually good for us. It is commonly called Strep thermophilus and is a lactic acid bacterium (like Lactobacillus), meaning that it is commonly found in fermented milk products like yogurt and sour cream.

Benefits of Strep. Thermophillus Probiotics

Strep. Thermophillus is often used in these food products to help break down lactose, the sugar in milk that many people cannot digest. For more information please see our lactose intolerance article.

Protection Against Diarrhea

Strep. Thermophillus has been studied for use in chemotherapy patients and in antibiotic associated diarrhea. In both cases it has been found to reduce damage to the intestinal lining and help to prevent the growth of bad bacteria. This helps to reduce diarrhea and sometimes even prevent it entirely.

How Can I Get More Strep Thermophilus?

Usually Strep. Thermophillus will be found in a multi-strain probiotic in combination with other probiotic strains to help colonize the gut and prevent diarrhea and gut damage. These formulas can come in powder or capsule and can be mixed into food or taken with meals to help colonize the gut with beneficial bacteria.
