Hi Marie09! Thanks for your question! I found an article that may be helpful that talks about probiotics and RA, https://rheumatoidarthritis.net/living/can-probiotics-help/
However, probiotics can affect each individual and any conditions they may have (like RA) differently, which is why it's important to talk to your doctor if you're interested in trying these. Your doctor can help review your specific situation with you and determine what probiotics may be beneficial. If you do get a chance to talk with your doctor, let us know what they say! Thanks again for your question, I hope the article helps some too! -Casey, RheumatoidArthritis.net Team
