A *dietary supplement*, also known as *food supplement* or *nutritional

vitamins, minerals, fiber, fatty acids, or amino acids, that may otherwise
not be consumed in sufficient quantities. Some countries define dietary
supplements as foods, while in others they are defined as drugs or other

The U.S. National Institutes of Health notes that none of these products
are intended for the prevention or treatment of any disease and in some
circumstances supplements are dangerous; adding that certain supplements
"may have value" for those who fail to consume a balanced diet. ^[1]

There are more than 50,000 dietary supplements available on the U.S. retail
market (broadly similar to the international market). Effects, if any, are
unproven by science. ^[2]

The annual retail value of supplements sold worldwide in 2011 was estimated
at $47 billion, including $25 billion in the U.S. (citation needed).
