(WXOW) -- A recent review by the Annals of Internal Medicine finds there is no clear evidence of the health benefits of vitamins or other supplements.
An editorial published this week tells people to stop wasting money on vitamin and mineral supplements. Physicians refer to three articles that look into the effectiveness for preventing chronic disease.
Authors of these studies concluded there was no clear evidence of a beneficial effect of supplements on mortality, cardiovascular disease or cancer. Another evaluation found no improvement in cognitive function among an older population using multivitamins.
The studies show that in some cases supplements can be harmful, like high doses of vitamin A or E.
Trends show dietary supplement use has increased. The supplement industry continues to grow, reaching $28 billion in annual sales in 2010.
"Most supplements do not prevent chronic disease or death," the editorial states. "Their use is not justified and they should be avoided."
