Probiotics are beneficial bacteria that are sometimes called friendly germs. They help maintain a healthy intestine and aid in digestion. They also help keep harmful bacteria and yeasts in the gut under control. Most probiotics come from food sources, especially cultured milk products. Probiotics can be taken as capsules, tablets, beverages, powders, yogurts, and other foods. In a small study Lactobacillus GG was associated with improved subjective well-being and trends in reduced symptoms of rheumatoid arthritis. However, the results were not statistically significant. More studies on the effects of probiotics on rheumatoid arthritis are needed.
Probiotics are generally considered safe and well tolerated. Avoid if allergic or hypersensitive to probiotics. Use cautiously if lactose intolerant.
