Can Lactobacillus rhamnosus GR-1Help With a UTI or a Vaginal Infection?
Lactobacillus rhamnosus GR-1 is a lactic acid bacteria from the genus Lactobacillus and the species rhamnosus. Like other Lactobacillus rhamnosus, it is a Gram-positive, rod-shaped bacterium which does not produce spores and is not capable of moving itself with flagella.
L. rhamnosus GR-1 was isolated from the urethra of a healthy woman. The urethra is a tube that connects the urinary bladder to the urinary meatus for the removal of fluids (urine) from a woman's body. Dr. Gregor Reid and Dr.
Andrew Bruce at Urex Biotech discovered and developed Lactobacillus
rhamnosus, GR-1® and then sold the
rights to Chr. Hansen of Denmark.
Is L. rhamnosus GR-1 Safe?
The Lactobacillus rhamnosus species as a whole are listed on the European QPS (Qualified Presumption of Safety) list. Lactobacillus bacteria as a whole are considered to be routinely encountered in the environment, in fermented foods and drinks, and are frequently isolated from feces. Unless a person is immune-compromised, Lactobacillus are generally considered safe. If you ever have any questions about your immune status, please talk with your doctor.
What Does Research On L. rhamnosus GR-1 Show?
Some studies show that it is very helpful for a vaginal infection such as a vaginal yeast infection or bacterial vaginosis, and also for a urinary tract infection (UTI).
For more information on the specifics of the probiotic Lactobacillus rhamnosus GR-1, including details of what studies have shown for the strain and at which dosages and duration, look for a future publication, "The Lactobacillus rhamnosus GR-1 Guide."
Where to Find Lactobacillus rhamnosus GR-1?
L. rhamnosus GR-1 is available, combined with Lactobacillus reuteri RC-14, in products such as Fem-Dophilus® and RepHresh Pro-B®. Always read ingredients prior to purchasing.

In Fem-Dophilus® , the recommended dosage is one capsule per day for
maintenance with 2.5 billion cfu of each strain per capsule. Increase to
two(2) capsules a day as needed, or use as directed by your qualified
health care consultant. Fem-Dophilus® is marketed by Jarrow and is
recommended to be refrigerated. |

RepHresh Pro-B (clinically called
Urex-Cap-5) is marketed by Lil’ Drug Store Products, Inc and contains 2.5 billion each of GR-1 and RC-14. The recommended dosage is one capsule per day. It can be
stored at room temperature, but I’d recommend refrigeration if possible
to prolong microbe life. |
