Is omega-3 fish oil good for the liver?

Take better care!: Don't waste your time, money, or health--liver "detoxing" is worthless, & liver supplements can't fix a diseased liver. If you indeed have liver disorder, see a specialist who can help design appropriate treatment for you. At this time, re-evaluate what you're taking that may hurt the liver (e.g. over-the-counter agents, herbals, too much alcohol--as you asked about before).
