Should healthy adults take vitamins?

In the past, many…: …docs would have answered "no" with the explanation that a nutritious diet should be adequate. Today, however, many docs feel vitamins are beneficial: people under much stress benefit from extra b & c. Vitamin d is being advised for many preventive reasons. Multivitamins often contain trace minerals essential to good health that many might not otherwise receive.

Not generally.: If you are eating a nutritious diet the answer is no. If you are eating something less then they might be beneficial. However, if that is the case, you have bigger concerns. There is no evidence that supra physiologic doses of any of the vits or minerals is beneficial.
