Grass-Fed Beef Liver (Freeze-Dried, Non-Defatted, Non-GMO, 100% Pasture-Raised, 45-Day Supply)

Grass-Fed Beef Liver (Freeze-Dried, Non-Defatted, Non-GMO, 100% Pasture-Raised, 45-Day Supply)

Nature’s Ultimate Multivitamin

3,000 mg / 45-Day Supply

Liver is one of the most nutrient-dense foods on the planet, and something our ancestors and early humans ate regularly for millions of years. 

MK Supplements' Grass-Fed Beef Liver is from 100% pasture-raised New Zealand cattle. Unlike other manufacturers, we use a gentle freeze-drying method to turn fresh liver into a powder before filling it into gelatin capsules.

Additionally, we don't use hexane or other harsh chemicals to defat our organ meats.

Instead, you get what we consider nature's ultimate multivitamin; a high-quality supplement that offers all the benefits of consuming fresh, grass-fed organ meat (without the strong taste).

Beef Liver Benefits

Liver is packed with bioavailable and highly-absorbable nutrients, enzymes and peptides that many Americans are deficient in, including choline, copper, folic acid, iron, potassium, selenium, preformed Vitamin A, Vitamin D, Vitamin B12 and zinc.

Liver is also one of the few dietary sources of bioavailable Vitamin K2 (not to be confused with K1, the much less bioavailable plant-based version) and hyaluronic acid. Getting sufficient amounts of Vitamin K2 is important for calcium absorption, especially if you take calcium supplements. 

Liver is also a rich source of coenzyme Q10 (CoQ10), an important antioxidant that can help improve mitochondrial function, promote healthy aging and longevity, and improve brain and heart health.

Combined, the nutrients found in liver are crucial for many of the body’s metabolic processes, including brain function, proper digestion and stable energy levels.

Why Beef Liver

There is overwhelming scientific evidence that Americans get insufficient vitamins and minerals from their diet, due in large part to the fact that our society has replaced nutritious organ meats — something we ate for millions of years — with breakfast cereals, highly-processed junk food and synthetic multivitamins.

But even plants have fewer nutrients than in the past, thanks to deteriorating soil quality, monocrops and the overuse of fertilizers and other chemicals.

Desiccated organ meat supplements are the easiest way to add highly bioavailable micronutrients back into your diet. 

For example, beef liver is jam-packed with valuable micronutrients like preformed Vitamin A, Vitamin B12 and iron (as well as many others). With over 25 nature-identical vitamins, minerals and cofactors, it’s nature’s ultimate multivitamin. 

In comparison, synthetic multivitamins offer high amounts of mostly lab-grown nutrients that the body can’t absorb and flushes out via urine. 

How to Use Beef Liver Capsules

  • Instructions

    Take four capsules per day, or up to six capsules per day if you suffer from severe micronutrient deficiencies or have increased nutritional requirements (e.g., due to your active lifestyle). Children can take two capsules per day, depending on their weight. Consistent and long-term use produces the best results. Ask us if you need help determining the right dosage.

  • Benefits

    Our Grass-Fed Beef Liver is a foundational supplement for any diet or health status (including paleo and keto dietary frameworks), helping to fill nutritional gaps and improve energy, mood, exercise performance, libido and more. Learn more in our guide to the health benefits of eating organ meat.

    Each serving of our Grass-Fed Beef Liver supplement contains 3 grams of freeze-dried liver. That's the equivalent of one ounce of fresh liver.

MK Supplements Beef Liver Nutrients

Nutrients in Beef Liver (Per Serving)

Jam-packed with valuable micronutrients like preformed Vitamin A, Vitamin B12 and iron (as well as many others), it’s nature’s ultimate multivitamin.

Liver’s diverse micronutrient profile provides the building blocks for a wide range of bodily functions, supporting the metabolism, immune system, skin, eyes, reproductive organs, mental health and more. Plus, its synergistic combination of vitamins and minerals can naturally boost energy levels by supporting mitochondria (the part of every cell responsible for energy production).

  • Vitamins

    Betaine (1.2 mg), Choline (93.3 mg), Vitamin A (4,732 IU), Vitamin B1 (0.1 mg), Vitamin B2 (0.8 mg), Vitamin B3 (3.7 mg), Vitamin B5 (2.0 mg), Vitamin B6 (0.3 mg), Vitamin B7 (10.3 mcg), Vitamin B9 (81.2 mcg), Vitamin B12 (16.6 mcg), Vitamin C (0.4 mg), Vitamin D (4.5 IU), Vitamin E (0.1 mg), Vitamin K (21 mcg)

  • Minerals

    Calcium (1.4 mg), Copper (2.7 mg), Iron (1.4 mg), Magnesium (5.0 mg), Manganese (0.1 mg), Phosphorus (108 mg), Potassium (87.6 mg), Selenium (11.1 mcg), Sodium (19.3 mg), Zinc (1.1 mg)

  • Other

    Coenzyme Q10 (1 mg), Hyaluronic Acid (25 mg)

  • Important Note

    Many synthetic multivitamin supplements contain significantly higher concentrations of vitamins and minerals. That's because your body doesn't absorb most of those nutrients due to their poor bioavailability. However, the nutrients in freeze-dried organ meats are highly absorbable, so you don't need excessive amounts. Additionally, it's virtually impossible to overdose on nutrients from real-food sources. So don't worry about getting a little more Vitamin A or iron than your body may need.

The micronutrient contents listed above are based on data from the USDA and European Food Database for fresh beef liver. Freeze-drying results in a loss of 5% or less of nutrients, and the exact breakdown varies from lot to lot.

    The hyaluronic acid, copper, zinc and selenium in liver are crucial for maintaining healthy skin and connective tissue.

  • Energy and Mood

    Liver is an excellent source of Vitamin B12, copper, heme-iron, CoQ10 and niacin, all of which are crucial for energy, optimal exercise performance, metabolism and mood.

    The highly absorbable B vitamins (riboflavin, folate and B12), amino acids (anserine, carnosine, taurine and l-carnitine), choline and zinc in liver are vital for brain health and cognition as well as neurotransmitter formation.

  • Immune Health & Longevity

    Selenium is a cofactor for the body’s antioxidant defenses and (together with copper) supports optimal immune function. Specific peptides found in liver — including liver expressed antimicrobial peptide (LEAP-2), hepcidin and ergothioneine — support immune health, detoxification and longevity pathways.

  • Teeth and Bones

    The Vitamin K2 in liver is crucial for bone and tooth health because it supports remineralization and absorption of calcium.
