A dietary supplement is a manufactured product intended to supplement a person's diet in the form of a pill, capsule, tablet, powder, or liquid. A supplement can provide nutrients that are either extracted from food sources or are synthesized (to increase the quantity of their consumption). The classes of nutrient compounds in supplements include vitamins, minerals, fiber, fatty acids, and amino acids. Dietary supplements may also contain substances that have not been confirmed as being essential to life, such as plant pigments or polyphenols, and so, by definition, are not necessarily nutrients. However, they may still be marketed as having a beneficial biological effect. Animals can also be a source of supplement ingredients; for example, collagen may be extracted from chickens or fish. Supplements are sold in multiple doses, ranging from one time usage to entire courses. They may also be enhanced with nutrient ingredients.
