Liver extracts, usually from pork and beef liver, are widely available in both liquid and dried form. Some preliminary research suggests that taking these extracts may be helpful in treating various medical conditions, though more research is needed to confirm their effectiveness. The source of the extract is more important than whether it is in liquid or dried form.
Benefits of Liver
People commonly eat poultry, beef, pork, lamb and fish liver, according to the European Food Information Council. Liver is a good source of vitamin A. iron, zinc, copper and manganese, and is a very good source of protein, vitamins C and D, various B vitamins, phosphorus and selenium.
Liver Extract
Liquid liver extract -- as well as desiccated liver -- has been marketed as an iron supplement for more than a century, according to Natural Standard research published by AARP. Whether in dried or liquid form, the extract is made from processed pig or cow liver that has had most of the fat and cholesterol removed. Preliminary data indicates that the dried or liquid extract may be helpful in treating a number of diseases and conditions such as hepatitis and other viral infections, anemia, certain cancers and chronic fatigue. But additional research is needed to confirm its effectiveness and safety.
Desiccated Liver
Desiccated liver is concentrated, dried liver that is sold in either powdered or tablet form, according to "Prescription for Natural Healing." It contains vitamins A, B-complex, C and D, as well as the minerals calcium, copper, phosphorus and iron. Dessicated liver is used to treat anemia and build healthy red blood cells. It also increases energy and reduced stress.
Cautions
Liver may contain heavy metals and other contaminants that accumulate in liver tissues, according to the European Food Information Council. For this reason, "Prescription for Natural Healing" recommends using only liver products that are derived from organically raised beef. In addition, the European Food Information Council notes that since liver contains large amounts of vitamin A, which can harm fetuses in excess amounts, pregnant women should seek medical advice before consuming liver in any form.
Bottom Line
Eating liver provides generous doses of various vitamins and minerals, but also large amounts of fat and cholesterol. Taking liquid extract in either liquid or desiccated form provides essential nutrients without the fat and cholesterol. More important than the form of liquid extract is that it come from organically grown animals.
