Is it safe to take ritalin (methylphenidate) and dietary supplements together?

Ritalin (methylphenidate) and suppleme: Yes, this is generally safe as long as the supplements are safe.

Need specifics: We would need to know what specific dietary supplements you plan to take, as some herbals and others can interact with pharmaceuticals. If all you mean is a good multivitamin, probiotic, and omega-3's like in fish oil, those are probably fine.

Depends on supplemen: Speak to your doctor about what you intend to take with Ritalin (methylphenidate). there may or may not be a negative interaction to the combination.
