The liver is a vital organ with functions ranging from detoxifying the body to 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 treat any liver damage is a great tool for overall health and wellness. Liver support supplements are especially helpful if you are dieting or trying to lose weight, have a poor diet, drink a lot of caffeine, drink alcohol, or smoke tobacco. A well-functioning liver has been shown to aid weight loss, as the liver is involved in much of metabolism, and the healthier your body is, the easier it is to get even healthier and maintain that well-being. There are also some prescription and over-the-counter medications that can damage the liver and liver function, and supporting the liver is a great way to protect the body from such damage.
