Science Ratings Health Concerns

Iron-deficiency anemia

3Stars Reliable and relatively consistent scientific data showing a substantial health benefit.
2Stars Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
1Star For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support and/or minimal health benefit.

Who is likely to be deficient?

As it is not an essential nutrient, no deficiency state exists.

How much is usually taken?

The recommended amount depends on the concentration, method of preparation, and quality of the liver extract.

Are there any side effects or interactions?

No side effects or adverse reactions have been reported. Liver extracts should not be used by people suffering from iron-storage disorders, such as hemochromatosis.

As the liver is a major filtering organ for many potentially toxic environmental chemicals, some doctors are concerned that consumption of liver extracts may result in increased intake of these chemicals.

At the time of writing, there were no well-known drug interactions with liver extracts.
