What are best supplements should i take for slipped disc ?! glucosamin and chondroitn?

Varies: There is really no known supplement that has been shown to treat a "slipped disc" . If you are having back pain, there is some thought that an anti-inflammatory diet can be helpful. This can be done just changing what you eat and not necessarily using supplements, but omega3s are among the most common supplements to treat inflammation. Keep your core strong, avoid smoking and obesity can help.

None: Glucosamine and chondroitin have no value in treating disc herniations. Neither do any other supplements.
