Let's be honest: eating liver a few times a week is a commitment. You need a butcher you trust, a recipe that works, and — for most of us — a way past the taste. Our grass-fed Beef Liver pills skip all of that. Each serving delivers the concentrated nutrition of fresh, pasture-raised liver, gently freeze-dried and sealed into a capsule you can take anywhere. It's all the nourishment of nose-to-tail eating, with none of the acquired taste.
Somewhere along the way, most of us started treating “tired” as normal — the afternoon slump, the second (and third) coffee, workouts that take more than they give. It doesn't have to be that way. Our Beef Liver capsules supply the raw materials your body actually runs on, and our customers tell us they feel the difference where it counts: steadier energy, a clearer head, and strength that lasts the whole day.
Beef liver is one of the most nutrient-dense foods on earth. For generations, it was prized above muscle meat and kept at the center of the family table. But modern diets have pushed organ meats aside, meaning we miss out on the vital micronutrients liver delivers in abundance — including natural choline, copper, folate, iron, selenium, preformed Vitamin A, and Vitamin B12.
Our MK Supps desiccated Beef Liver bridges that nutritional gap effortlessly. It takes just seconds a day to restore the highly bioavailable nourishment of the fresh organ directly to your diet. We captured this ancestral superfood in a simple supplement, giving you an incredibly easy way to reclaim those missing vitamins and minerals.
This whole-food approach offers a massive advantage over average multivitamins. Most supermarket and drug store options rely on synthetic, lab-created formulas that the body struggles to recognize. Because the nutrients in our beef liver exist in their natural, food-bound state, your body instinctively knows how to absorb them. This ensures far more of every dose actually reaches your cells, while being gentle on the stomach and perfectly safe for daily use.

View Product →Beef liver is one of the few dietary sources of bioavailable Vitamin K2 — not to be confused with K1, the far less bioavailable plant-based form. Adequate K2 matters for directing calcium where it belongs, supporting bone and dental strength, which makes it especially relevant if you supplement with calcium.
Liver is also rich in Coenzyme Q10 (CoQ10), an antioxidant that supports mitochondrial function — the energy-producing engine inside every cell. CoQ10 is associated with healthy aging, cardiovascular health and cognitive function, and natural dietary sources of it are relatively rare.
Together with liver’s hyaluronic acid content, these cofactors are a large part of what sets whole-liver nutrition apart from a standard multivitamin.
Every batch begins on regenerative ranches across the United States, where cattle graze on open pasture, grass-fed and grass-finished the way nature intended. We only use cattle raised without hormones, antibiotics, pesticides or GMOs, ensuring that our Beef Liver capsules are 100% pure and additive-free.
Our beef liver is gently freeze-dried in small batches — never exposed to high heat or harsh solvents — to protect the fragile vitamins, enzymes and peptides that make it so valuable. Freeze-drying removes only the water, locking in nutrients at their natural potency with a loss of 5% or less compared to fresh organ meat.
We prioritize purity and potency with rigorous third-party lab testing at every stage of production. Transparency matters, so we make our test results available in our help center. You can learn more about our five-stage testing process in this blog article.
Our Beef Liver capsules come in amber glass bottles with metal lids (never plastic). Dark glass helps preserve nutrient integrity by protecting against light and oxygen, while eliminating the risk of microplastic leaching. It’s safer for you, better for the environment and fully recyclable — giving you peace of mind with every bottle.

Each serving delivers over 25 nature-identical vitamins, minerals and cofactors — the equivalent of roughly one ounce of fresh liver.
Vitamins A, D, E and K2 support immune defense, bone strength, hormone balance and antioxidant activity.
B12, riboflavin, folate, niacin and choline promote red blood cell formation, cardiovascular function, brain health and energy metabolism.
Essential minerals for thyroid function, antioxidant defense, mood and connective tissue health.
The most bioavailable form of iron. Essential for endurance, oxygen delivery and recovery.
A rare antioxidant amino acid that supports detoxification and longevity pathways.
Liver-expressed antimicrobial peptide that’s involved in immune defense and glucose metabolism.
Per serving · 5 capsules · 3,000 mg
Values based on USDA and European Food Database data for fresh beef liver. Freeze-drying results in a loss of 5% or less; exact amounts vary from lot to lot.
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).
The Vitamin A (retinol) and B vitamins in liver play a crucial role in vision, helping to maintain a clear cornea (which is the outside covering of your eye).
The hyaluronic acid, copper, zinc and selenium in liver are crucial for maintaining healthy skin and connective tissue.
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.
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.
The Vitamin K2 in liver is crucial for bone and tooth health because it supports remineralization and absorption of calcium.
Beef Liver is nature’s multivitamin — rich in preformed Vitamin A (retinol), B12, heme iron, copper, choline and folate. These nutrients support energy metabolism, skin and collagen integrity, immune function, thyroid health, and red‑blood‑cell formation.
Yes. Every batch is tested for heavy metals and microbial contaminants (bacteria, yeast, mold), among other quality checks. You can find the results in our help center.
The standard serving is five capsules per day. New to organ supplements? Start with 1-2 capsules and ramp up over several days. Take them all at once or split doses — both approaches work.
Any time. Many customers take it with their first meal. Consistency matters more than timing, and you can split the serving across the day.
Ye. Great pairings include Ironclad or Female Vitality (for extra iron support), Bone & Marrow, and Collagen & Colostrum. Avoid doubling up on liver‑heavy formulas (e.g., Beef Organs) unless you're aiming to increase your intake of specific micronutrients (e.g., Vitamin A).
Yes. You can open the capsules and sprinkle the contents on food or mix into a cool beverage. Expect a naturally rich, meaty aroma; avoid high heat to protect nutrients.
No. There have not been any reported cases of vitamin A toxicity from consuming the liver of ruminant animals (e.g., cows). All reported instances stemmed from consuming synthetic supplements or polar bear/seal liver (both of which have dramatically higher levels of Vitamin A than beef liver).
