Liver is a vital organ, with functions ranging from detoxifying the body, playing a role in digestion and metabolism, and even protein synthesis. No human can live without the liver, so using liver support supplements to protect and help heal any damage done to the liver is a good aid to aid in general health and well being. Liver support supplements are particularly useful if you are on a diet or trying to lose weight, have a poor diet, drink a lot of caffeine, drink alcohol, or smoke tobacco. A high functioning liver has been shown to aid in losing weight, as the liver is involved in much of the metabolic process and the better health your body is in, the easier it is to become even healthier and to maintain that well-being. There are also certain prescription and non-prescription drugs that can damage the liver and liver function, and supporting the liver is an excellent way to protect your body from such injury.
