Beef liver as a superfood
Beef liver is rightly regarded as one of the most nutritionally rich foods on the planet. Its exceptional nutrient profile lies not only in the high content of individual nutrients but especially in its natural and complex matrix. Nutrients in liver are often present in synergistic combinations that enhance their absorption and utilization in the body. For example, adequate zinc intake is important for vitamin A metabolism, while copper plays a role in iron metabolism. This natural synergy offered by liver as a whole food may be more effective than isolated supplementation of individual nutrients.
Beef liver contains a wide range of macro- and micronutrients in a highly bioavailable form. In terms of macronutrients, beef liver is an excellent source of high-quality protein containing all essential amino acids, which are vital for tissue building and repair, enzyme and hormone synthesis, and many other essential functions. A 100-gram portion of beef liver contains approximately 20–22 grams of protein.
Beef liver also contains significant amounts of micronutrients.
Vitamin A: The most prominent vitamin in beef liver is vitamin A in the form of retinol, which is the most bioavailable form the body can use immediately. Even a small portion of liver can meet—and significantly exceed—the recommended daily intake of this vitamin, which is essential for vision, immune function, and the health of mucous membranes and skin.
B vitamins: Liver is also a rich source of B vitamins. It is one of the richest natural sources of vitamin B12, which is necessary for proper nervous system function, red blood cell formation, DNA synthesis, and energy metabolism. Liver contains significant amounts of other B vitamins, particularly riboflavin (B2), niacin (B3), pantothenic acid (B5), vitamin B6, and folate (B9), which are involved in hundreds of enzymatic reactions in the body, supporting energy production, nervous system health, hormonal balance, and cellular health.
Iron: Liver is also an excellent source of highly bioavailable heme iron, which the body absorbs much more efficiently than non-heme iron from plant sources. Iron is essential for hemoglobin formation, oxygen transport in the blood, anemia prevention, and maintaining energy levels.
Zinc: This mineral plays a crucial role in immune function, wound healing, DNA synthesis, testosterone production, and over 300 enzymatic reactions. One portion of liver can cover up to 40% of the daily zinc requirement.
Copper: Liver is one of the richest sources of copper. It is an essential trace element necessary for collagen and elastin production, iron metabolism, nervous system function, and cellular protection against oxidative stress.
Selenium: A powerful antioxidant that protects cells from damage caused by free radicals and is important for proper thyroid function and the immune system.
Phosphorus: Together with calcium, it is a fundamental building block of bones and teeth and plays a role in energy metabolism.
Coenzyme Q10 (CoQ10): Liver is also a good source of CoQ10, an antioxidant involved in energy production in the mitochondria (the cell’s powerhouses) and cellular protection against oxidative damage. It is especially important for heart health.
Choline: This essential nutrient is key for brain health (memory, learning), liver function, fat metabolism, and the integrity of cell membranes.
Trime “Grass-finished” freeze-dried liver = premium superfood with naturally higher nutrient content
Trime beef liver from cattle raised exclusively on grass (known as "grass-finished" or "100% grass-finished") in a regenerative agriculture system differs significantly in nutritional value from liver from conventionally raised cattle fed primarily on grain.
The difference between grass-finished and grass-finished
The term "grass-fed" intuitively evokes the image of cattle grazing on green pastures. However, the reality is much more complex. This term only indicates that the animal consumed grass at a certain stage of its life, but does not specify how long this stage lasted or what the animal was fed for the rest of its life. In the final stage of fattening, animals may be moved to large-capacity feedlots, where they are fed a high-energy grain-based mixture (mainly corn). This process, known as "finishing," aims to rapidly increase weight and create intramuscular fat (marbling). Even meat from animals raised in this way can be legally labeled as "grass-fed" because the animals were actually fed grass in the early stages of their lives.
In contrast, "grass-finished" (or "100% grass-fed") means that the cattle have been fed exclusively on grass and other forage throughout their lives. In the summer, they graze on fresh pasture, and in the winter months, they are fed preserved forage such as hay or silage (fermented grass).
The "grass-finished" label is therefore a more reliable indicator of true pasture-raised cattle and also guarantees higher nutritional quality.
Feed has a significant impact not only on the fat composition of the meat, but also on the overall content of vitamins, antioxidants, and other bioactive substances. The animal's diet is thus directly reflected in the quality and nutritional value of the final product.
Fatty Acid Profile:
Omega-3 vs. Omega-6: Beef products from grass-finished cattle show significantly higher levels of beneficial omega-3 fatty acids (such as alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA)) and a more favorable omega-6 to omega-3 ratio. Some sources indicate that grass-fed beef can contain two to six times more omega-3s. EPA levels may be up to ten times higher and DHA three times higher compared to grain-fed animals. A lower omega-6 to omega-3 ratio is associated with anti-inflammatory effects and a reduced risk of chronic diseases.
CLA (Conjugated Linoleic Acid): Grass-finished beef liver contains higher amounts of CLA, a group of polyunsaturated fatty acids with proven potential anti-obesity and muscle-building effects.
Vitamin and Antioxidant Content:
-
Vitamin E (α-tocopherol): Grass-finished beef is richer in vitamin E, especially α-tocopherol, a key antioxidant that protects cell membranes from oxidative damage. α-tocopherol content can be up to three times higher.
-
Vitamin K2: Grass-finished freeze-dried liver contains significantly more vitamin K2 compared to liver from conventionally raised animals. This difference is due to a higher intake of phylloquinone (vitamin K1) from fresh green pasture, which is efficiently converted to vitamin K2 MK-4 in ruminant animals. The higher vitamin K2 content is a significant nutritional benefit, especially for supporting bone and vascular health.
-
Provitamin A Carotenoids: Meat and liver from grass-finished cattle contain higher levels of carotenoids such as β-carotene, which are precursors to vitamin A and have antioxidant properties of their own.
Other Phytonutrients: Meat from pasture-raised animals may contain higher levels of various beneficial phytonutrients that animals ingest from plants. Studies have identified hundreds of compounds whose levels differ between pasture-finished and grain-finished beef, with pasture-finished meat showing, for example, 2.6 times higher levels of phenolic antioxidants.
Regenerative agriculture is a holistic approach to food production that focuses not only on yields but also on soil health, ecosystems, animal welfare, and ultimately human health. Liver from cattle raised in such systems carries the stamp of this comprehensive care and offers the potential for even higher quality and nutritional value.

Benefits of Freeze-Dried Liver
Freeze-drying, or lyophilization, is a modern and gentle preservation method that exceptionally preserves the nutritional value and overall quality of food. Unlike thermal drying, it has minimal impact on the content and biological activity of vitamins, minerals, enzymes, and other bioactive compounds. Freeze-dried products also retain their original structure, color, taste, and aroma much better.
Other practical benefits of freeze-drying include:
-
Long shelf life, even at room temperature, while preserving high nutritional value.
-
Low weight: The final product is very lightweight, making it easy to transport, store, and handle.
-
Ease of use: Freeze-dried liver is often available in powder or capsule form, allowing for very simple consumption and precise dosing. This format is ideal for individuals who may be averse to the taste or texture of fresh liver or for those seeking a convenient way to incorporate this nutrient-dense food into their diet.
Health Benefits of Consuming Beef Liver
Thanks to its extraordinarily rich nutritional profile, consuming beef liver offers a wide range of potential health benefits that support optimal bodily function on many levels.
Immune System Support: Liver is packed with nutrients that are essential for a strong and resilient immune system. The high vitamin A content is crucial for maintaining the integrity of mucous membranes, which form the first line of defense against pathogens, and for the proper development and function of immune cells. B vitamins, zinc, selenium, and copper also contribute to immune regulation, antibody production, and protection against infections.
Increased Energy and Fatigue Reduction: One of the most frequently reported benefits of liver consumption is increased energy and reduced fatigue. This is largely due to its high content of heme iron, which is essential for hemoglobin production and oxygen transport to cells, including muscles and the brain. The B vitamins also play a key role in energy metabolism, the process of converting food into usable energy.
Eye Health: The high amount of vitamin A in the form of retinol makes liver one of the best foods to support eye health. Retinol is essential for the production of rhodopsin, the visual pigment in the retina that allows us to see in low-light conditions. Adequate vitamin A intake may help prevent night blindness, dry eyes, and macular degeneration — a leading cause of vision loss in older adults.
Brain Health and Cognitive Function: Several nutrients found in liver play key roles in brain health and cognitive function. Vitamin B12 is essential for maintaining healthy nerve cells and the formation of myelin, the protective sheath around nerve fibers. Choline is a precursor to acetylcholine, a critical neurotransmitter for memory and learning, and it also supports fetal brain development. Omega-3 fatty acids, which are found in higher amounts in liver from grass-finished cattle, are also known for their positive effects on brain health and may help reduce the risk of age-related cognitive decline. Some studies even suggest regular liver consumption may be linked to better memory.
Muscle Mass and Recovery Support: Liver is an excellent source of complete protein, meaning it contains all essential amino acids that the body cannot produce on its own and must obtain from food. These amino acids are the fundamental building blocks for the growth, repair, and maintenance of muscle tissue. It is no coincidence that bodybuilders and strength athletes have historically included liver in their diets to support muscle growth and recovery after intense training.
Skin Health: Vitamin A is essential for the healthy growth and regeneration of skin cells. Together with other antioxidants present in liver — such as vitamin E (especially in the grass-finished variant) and selenium — it may help maintain healthy, elastic skin and potentially reduce signs of aging.
Consumption Recommendations
Beef liver is a naturally rich source of vitamin A in the form of retinol, which is vital for numerous physiological functions. Although vitamin A is essential, excessive intake can lead to toxicity (hypervitaminosis), especially with long-term consumption of high doses. Pregnant women should be particularly cautious, as too much retinol may increase the risk of birth defects.
The European Food Safety Authority (EFSA) has set a tolerable upper intake level of vitamin A for adults, including pregnant women aged 19–50, at 3000 µg retinol activity equivalents (RAE) per day.
Freeze-dried beef liver offers the advantage of controlled dosing — for example, 6 capsules may contain approximately 1013 µg RAE. Nevertheless, it is important to account for total daily vitamin A intake from all sources, including regular food and other supplements.
Conclusion: A Comprehensive View of Freeze-Dried Liver from Regenerative Agriculture
Freeze-dried beef liver, especially when sourced from grass-finished cattle raised in a regenerative agriculture system, represents an exceptionally concentrated source of a wide range of essential nutrients. Its nutritional profile is rich in highly bioavailable vitamin A, a complex of B vitamins (especially B12), heme iron, zinc, copper, selenium, choline, and coenzyme Q10. These nutrients work synergistically to contribute to numerous health benefits, including immune system support, increased energy levels, maintenance of healthy vision, muscle mass support, and cognitive function. The added value of regenerative farming is reflected in a better fatty acid profile, with higher levels of beneficial omega-3s, as well as higher levels of vitamins and antioxidants such as vitamin E, vitamin K2, and carotenoids.
