We all need vitamins and minerals.
What we may not need are vitamins and minerals that come in a bottle.
According to the National Institutes of health, about a third of all Americans age 1 and older take a multi-vitamin/mineral (MVM) supplement. NIH says that MVMs are a nearly $5.5 billion industry, making up more than a third of the over $13 billion in vitamin/supplement sales annually.
So, vitamins are big business.
A number of recent studies, however, doubt the efficacy of MVMs and other supplements.
A 2006 study is blunt in its assessment.
“Considering only published, randomized, controlled clinical trials, the investigators found that use of MVMs did not reduce the risk of any chronic disease,” according to the NIH.
