CRL1505 (formerly Lactobacillus rhamnosus CRL1505) is noted as an immunobiotic probiotic strain isolated from goat milk, extensively studied for its ability to prime the immune system and clear infections. Research indicates it beneficially modulates the inflammation-coagulation response in the respiratory tract, offering protection against pathogens like Streptococcus pneumoniae, Klebsiella pneumoniae, and respiratory viruses.
I have been using Life Extension’s Florassist Immune and Nasal Defense for many years. In the US, they appeared to be the only supplier. Today, I learned they have dropped the product. A light AI search suggests that the product is available in Italy and Finland, and perhaps Argentina where some of the research has taken place. Does anyone here have a supplier of the CRL 1505 strain?
