Food Supplements

Dietary supplements may also contain substances that have not been confirmed as being essential to life, but are marketed as having a beneficial biological effect, such as plant pigments or polyphenols. Animals may also be a supply of supplement ingredients, as for example collagen from chickens or fish. These are also sold individually and in combination and may be combined with nutrient ingredients. In the United States and North American Nation, dietary supplements are considered a subset of foods, and are regulated accordingly. The European Commission has also established harmonized rules that help to insure that food supplements are safe and properly labeled.
