Condition

Chronic Liver Disease

Chronic liver disease is long-lasting liver damage, where inflammation and scarring gradually interfere with filtering blood and making bile. S-adenosylmethionine has the most research behind it, but a review found no clear difference in bilirubin, while liver cell content went up with TUDCA in one small study. That study involved only five people, so the evidence overall is limited.
