Eating Animal Liver? Is It Good For You?

Animal liver has been consumed as food by humans for centuries. Livers of mammals, fowl, and fish like pork, lamb, veal, beef, chicken, goose, and cod livers are widely available from butchers and supermarkets. In some European countries, livers of stingrays and burbots are sold and form part of local cuisines.

If you can’t get your hands on raw beef liver to add to your diet or that sounds a bit daunting, you could look into supplementation. Each of the beef liver supplements we have included in the list below will allow you to incorporate the benefits into your daily routine, in the most straightforward way.

Ancestral Supplement’s GrassFed Beef Liver Capsules – What Customers Have To Say

Here are some reviews from customers regarding their experience with the supplement.

“For months, I was having issues with major hair loss (thyroid and other labs were normal). My doctor was at a loss. I was losing handfuls of hair in the shower and I actually “developed” a bald spot and chopped my long hair to chin length. It might sound vain, but this was very depressing for me.

Benefits of Beef Liver Supplementation

Eating animal liver is a good way to help you meet your daily recommended amount of vitamins and minerals and reduce the risk of nutrient deficiency. 

Beef liver, in particular, is one of the best animal-based sources of vitamin A. It provides more than 100% of the body’s daily vitamin A requirement. Having sufficient amounts of vitamin A lowers the risk of conditions like respiratory tract infections and certain types of cancer. It’s also an excellent source of high-quality protein, as it provides all of the essential amino acids. In fact, over a quarter of beef liver is made up entirely of protein.

Beef liver also contains the following minerals essential for optimal health:

  • Zinc  – a nutrient that helps your immune system and metabolism function. Zinc is also essential in reducing inflammation, boosting immune health, reducing the risk of age-related diseases, facilitating faster wound healing, and preventing acne.
  • Iron – the body needs iron for growth and development. It facilitates the production of hemoglobin and myoglobin, generates energy and focus, promotes gastrointestinal processes, boosts the immune system, and regulates the body temperature.
  • Folate – a vital mineral in red blood cell formation and for healthy cell growth and function. The nutrient is especially important during the early stages of pregnancy to lower the risk of congenital disabilities in the brain and spine.
  • Phosphorus aids in the formation of bone and teeth. It helps the body utilize carbohydrates and fats and facilitates protein production for the growth, maintenance, and repair of cells and tissues.
  • Selenium – plays an important role in metabolism and thyroid function and helps protect the body from damage caused by oxidative stress. Selenium can also help boost the immune system and even reduce the risk of heart diseases and cognitive decline.
  • Copper – a mineral essential for energy production. Like iron, it enables the body to form red blood cells. It helps maintain healthy bones, blood vessels, nerves, and immune function, contributing to iron absorption and cutting the risk of cardiovascular disease and osteoporosis.

Side Effects

While beef liver may be considered a superfood, not everyone can fully enjoy its benefits and may even experience adverse health effects, and the same can be said about taking beef liver supplements.

For example, since beef liver is rich in cholesterol and vitamin A, eating large portions of liver or consuming it every day is not recommended because it can cause a spike in your cholesterol levels and cause vitamin A toxicity. The latter can cause drowsiness, irritability, abdominal pain, nausea, vomiting, coarse hair, and alopecia of the eyebrows. It might also lead to liver damage.

Beef liver sometimes contains traces of antibiotics, which could be due to the cows receiving antibiotics around the time of their slaughter. It could be hazardous to human health and cause allergic reactions, anaphylaxis, and disruptions in the development of embryos. 

Frequently Asked Questions

Can beef liver supplements interact with other medications?

Some medications are known to interact with vitamin A, and since beef liver is a significant source of vitamin A, anyone taking medications such as acitretin, alitretinoin, bexarotene, cholestyramine, isotretinoin, tretinoin, or warfarin should consult with their physician first before taking beef liver either in food or in supplement form.

Can pregnant women take beef liver supplements?

While beef liver is rich in vitamin A and is important for fetal development, high doses of this vitamin can have negative health effects. For example, it can have teratogenic effects, disturbing the development of the embryo or fetus and even resulting in spontaneous abortion.

At any rate, pregnant or nursing mothers should consult a physician before taking this or any dietary supplement.

Is it safe for people with gout?

People with gout should avoid beef liver or red meat at all costs. Red meats like beef and pork contain more purines than white meats, and organ meats like the liver and tongue are particularly high in purines, and consuming them could increase uric acid levels and spurs a gout attack.

Final Take

Beef liver is a nutrient-dense superfood that promises several potential health benefits, such as supporting the immune and nervous systems, boosting energy and mood, reducing inflammation, and lowering the risk of many diseases. However, taking too much of it can do more bad than good for your health, so it’s important to practice moderation at all times. 

Before considering any beef liver supplement, always ask your doctor’s advice first to rule out any possible health risks and side effects.
