Background
Liver extract is a product that comes from animal liver, most commonly from cattle. Liver extract is used to make medicine.
People take liver extract by mouth or by injection for various conditions, especially for liver health or as a source of iron and vitamin B12, but there is no good scientific evidence to support these uses.

Safety Safety definitions
When taken by mouth: There isn't enough information to know if liver extract is safe. Since some preparations of liver extract come from animals, there is concern about possible contamination from diseased animals. However, so far there are no reports of diseases in humans that were caused by ingestion of contaminated liver.
Too much iron in the body, including a condition called hemochromatosis: Liver extract contains iron and might make iron metabolism disorders worse. If you have one of these disorders, don't use liver extract.
Special Precautions & Warnings:
Pregnancy and breast-feeding: There isn't enough reliable information to know if liver extract is safe to use when pregnant or breast-feeding. Stay on the safe side and avoid use.Too much iron in the body, including a condition called hemochromatosis: Liver extract contains iron and might make iron metabolism disorders worse.

Effectiveness
NatMed Pro rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, Ineffective, and Insufficient Evidence to Rate.
Possibly ineffective Effectiveness definitions
- Chronic fatigue syndrome (CFS). Some research suggests that injecting a combination of bovine liver extract, folic acid, and vitamin B12 for 3 weeks does not seem to improve fatigue in people with CFS.
Insufficient evidence Effectiveness definitions
- Swelling (inflammation) of the liver caused by the hepatitis C virus (hepatitis C). Early research suggests that injecting liver extract plus flavin adenine dinucleotide intravenously (by IV) or as a shot into the muscle might improve response to interferon-alpha or interferon-beta therapy in people with hepatitis C.
