Could a simple supplement soothe arthritis? small study investigates

This study tested whether a short-chain fatty acid (SCFA) supplement, taken by mouth, could change gut bacteria and immune responses in people with rheumatoid arthritis (RA) who did not get enough help from methotrexate. About 20 to 35 adults with RA took the supplement for one to two months. Researchers collected blood, stool, and urine samples to measure changes in gut microbes and immune cells, aiming to understand how the supplement might work rather than directly treat symptoms.
