Lactobacillus jensenii (L. jensenii) is a type of probiotic ("good" bacteria) found naturally in the human body. It's also found in fermented foods.
"Good" bacteria such as L. jensenii might help the body break down food, absorb nutrients, and fight off "bad" organisms that might cause diseases. These bacteria are sometimes added to fermented foods like yogurt and also found in dietary supplements.
People use L. jensenii for many different purposes, but there is no good scientific evidence to support its use.
Don't confuse L. jensenii with other probiotics, or with fermented food products such as fermented milk, kefir, or yogurt. These are not the same. Also note that the Lactobacillus genus was split up into 25 different genera in April 2020. Many species were reclassified at this time, but L. jensenii remains in the Lactobacillus genus. Its name did not change.
Is It Effective?
There is interest in using L. jensenii for a number of purposes, but there isn't enough reliable information to say whether it might be helpful.
Is it Safe?
When taken by mouth: L. jensenii is possibly safe for most people. Probiotics similar to L. jensenii have been used safely and seem to be well-tolerated.
Special Precautions & Warnings:
Pregnancy and breast-feeding: There isn't enough reliable information to know if L. jensenii is safe to use when pregnant or breast-feeding. But there are no reasons to expect safety concerns when used appropriately.
Children: There isn't enough reliable information to know if L. jensenii is safe for children, including very small premature infants.
Weakened immune system: Probiotics have caused blood infections in a small number of people with weakened immune systems. If you have a weakened immune system, talk with your healthcare provider before taking probiotics, including L. jensenii.
Damaged heart valves: Probiotic preparations can cause an infection in the inner lining of the heart chambers and heart valve. This is extremely rare, but people with damaged heart valves should stop taking probiotics, including L. jensenii, before dental procedures or surgical procedures.
