Extracts of beef (bovine) liver are a rich natural source of many vitamins and minerals, including iron.
Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
3 Stars Reliable and relatively consistent scientific data showing a substantial health benefit.
2 Stars Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
1 Star For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
If deficient: several grams per day for up to one year under medical supervision
Bovine liver extracts provide the most absorbable form of iron—heme iron—as well as other nutrients critical in building blood, including vitamin B12 and folic acid.
Liver extracts from beef are a rich natural source of many vitamins and minerals, including iron. Bovine liver extracts provide the most absorbable form of iron—heme iron—as well as other nutrients critical in building blood, including vitamin B12 and folic acid. Liver extracts can contain as much as 3–4 mg of heme iron per gram.
The recommended amount depends on the concentration, method of preparation, and quality of the liver extract.
Liver extracts are available as nutritional supplements in capsules and tablets.
As it is not an essential nutrient, no deficiency state exists.
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.
