I once was told by a doctor:
"There's no drug that will make a healthy person more healthy"
In response to some question I had about a supplement. I've spent some time wondering if this is always true or not. For instance: is fish oil only a good supplement for someone with a heart condition. If not, would it be considered part of a healthy diet?
I've wrestled with this when walking past the supplements at the pharmacy many times. Whatever the answer, I've found this thread a very good source of knowledge.
