What truly is considered older anyway? Most older woman I know do not eat enough to sustain the vitamin and minerals needed for their best health. So my guess is that it is worth the risk for many. A lot of elderly woman I know actually are anorexic as a lot of them work so hard to stay thin and as we all know when one is old the metabolic rate crawls even with a decent workout regime.
This says that some, not all, supplements may be harmful.
