Essence of chicken is a type of liquid nutritional supplement that is generally derived from cooking whole chickens down into a liquid. Any animal fats are generally removed from the liquid, in order to produce a nutritional supplement that contains little or no cholesterol. Essence of chicken is said to support health, promote healing, increase metabolism, and relieve fatigue. It is said to have its origins in the kitchens of England's King George IV. Cooks there are said to have concocted this mixture as a way to help the king improve his flagging health.

Manufacturers often stress that essence of chicken is not the same thing as chicken broth or chicken soup. Some have described this liquid nutritional supplement as a highly concentrated version of chicken broth. Essence of chicken doesn't necessarily have a strong chicken flavor. Many users report that this liquid supplement is largely tasteless, or that it has a bitter taste.

The supplement known as essence of chicken is believed to provide all the same nutrients found in chicken or chicken soup. Manufacturers typically stress that a serving of essence of chicken can provide up to three times as many nutrients as a serving of chicken soup or a normal serving of chicken meat. Fats and cholesterol are typically removed from essence of chicken, so it is generally considered safe for people suffering from heart problems and high blood cholesterol.

Most essence of chicken supplements are manufactured without added preservatives, chemicals, or flavorings. Stimulants, such as caffeine, generally aren't included in the ingredients of this product. Essence of chicken is, however, sometimes combined with ginseng and other liquid supplements, which may have a stimulant effect.
