How does Liver Extract work?

Liver extract contains vitamin B12, folic acid, and iron. In animals, it seems to increase the number of liver cells. It is not known how liver extract might work for medicinal uses in people.

Are there safety concerns?

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.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There is not enough reliable information about the safety of taking liver extract if you are 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. If you have one of these disorders, don't use liver extract.

Dosing considerations for Liver Extract.

The appropriate dose of liver extract depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for liver extract. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
