Beef liver is one of the most nutrient-rich foods there is. Even so, it hardly ever ends up on your plate these days.
In 100 grams, it contains more vitamin A, vitamin B12, and copper than almost any other food. No vegetable or muscle meat comes close to this density.
Here you will learn which nutrients it contains, how healthy beef liver is, and how much is appropriate per person.
Why beef liver is so nutrient-rich
The liver is the body's metabolic center. Vitamin A, vitamin B12, folate, and copper are stored here. That is why liver is not ordinary meat, but a concentrated storehouse of nutrients.
A common misconception is that the liver is a filter that stores toxins. It transforms harmful substances so that the body can excrete them. What can accumulate as the animal ages are heavy metals such as cadmium. That is precisely why the source matters.

What vitamins does beef liver contain?
Vitamin A as retinol
Beef liver is the most concentrated natural source of vitamin A. The form is crucial: In the liver, vitamin A is present as retinol, meaning it is ready for use. Plant sources provide beta-carotene, which the body first has to convert, and how well this works varies from person to person.
Vitamin A contributes to the maintenance of normal vision, normal skin and mucous membranes, and normal iron metabolism.
Vitamin B12 and the B vitamins
Vitamin B12 is found almost exclusively in animal foods, and beef liver is the richest source. B12 contributes to normal energy metabolism, the normal functioning of the nervous system, and the reduction of tiredness and fatigue.
It also contains riboflavin and folate. Both are involved in energy production in the mitochondria - where your body actually produces energy.
Beef liver and iron: how high is the iron content?
The iron content is around 4.9 mg per 100 grams. The point is not the amount but the form: liver provides haem iron, which the body absorbs much better than iron from legumes or grains. Iron contributes to normal oxygen transport in the blood and to the reduction of tiredness and fatigue.
Copper and vitamin A are both needed for iron metabolism, and beef liver provides all three together. Copper contributes to normal iron transport in the body.
Is beef liver healthy?
Yes. Beef liver provides exactly the nutrients that are often lacking in today's diet, in a form that your body can readily use.
The difference from a multivitamin lies in the matrix. In the liver, the nutrients are combined with their co-factors, just as they occur in nature. Your body recognizes them as food.
There is one limitation: liver is so nutrient-dense that it is not an everyday food in large portions. Vitamin A in particular has a clear upper limit.
How much beef liver per person?
For preformed vitamin A, the tolerable upper intake level for adults is 3,000µg per day. A 100-gram portion of beef liver exceeds this amount. Therefore, the recommendation is to limit liver and offal to about once a month.
As a guide:
- 100 to 150 grams, once or twice a month
- Not as a daily side dish
- Children need significantly less
- Or: 5 capsules per day
The maximum amount refers to continuous daily intake. A single portion is not a problem; regular excess over several months would be.
Organic pasture-raised beef liver: why origin matters
Because the liver processes metabolic products, it reflects how the animal lived and what it ate. Residues from feed and heavy metals are more likely to be an issue in intensive farming.
What you can rely on:
- Organic certification and controlled feeding
- Grass-fed animals from pasture-based farming
- Traceable origin instead of anonymous bulk goods
- Young animals, as heavy metals accumulate with age
Organic pasture-raised beef liver costs more than conventional products. For an organ that reflects precisely these differences, this is the wrong place to save money.
If you do not like liver: the simpler alternative
The most common argument against liver is the taste. Then there is the effort involved in buying, preparing and eating it promptly. That is precisely why so few people eat liver regularly, even though they intend to.
Our organic beef liver capsules are made from organic beef liver from Estonian pasture-raised cattle, with no additives and a neutral taste in the capsule.
What are beef liver capsules good for?
For people who want the nutrient density of liver but neither the taste nor the preparation. They provide iron, vitamin B12, vitamin A, choline and copper in the form in which they occur in the food.
Regularity is another factor. Instead of one large portion every few weeks, you get a small, consistent amount spread throughout the day.
Conclusion
Beef liver is one of the most nutrient-dense foods we know. Vitamin A as retinol, vitamin B12, copper and heme iron in a combination that hardly any other food offers.
Just not as an everyday food in large portions. If you do not like the taste, dried beef liver is a straightforward alternative.
Frequently asked questions
Which vitamins does beef liver contain? Mainly vitamin A as retinol, vitamin B12, riboflavin (B2), folate and vitamin B6. It also contains copper, iron, zinc, selenium, choline and coenzyme Q10.
How much beef liver per person? 100 to 150 grams, once or twice a month. The reason is the high content of preformed vitamin A, for which a maximum daily amount of 3,000 µg applies.
How much iron does beef liver contain? Around 4.9 mg per 100 grams, in the form of heme iron. The body absorbs this much better than plant-based iron.
