MK Supplements Grass-Fed Beef Liver - Features

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 (instead of heat) 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).



Liver is packed with bioavailable and highly-absorbable nutrients 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.

MK Supplements Grass-Fed Beef Liver contains 100% bioavailable micronutrients.

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 the urine instead.

Great product replaced my multivitamin

Starting my 3rd bottle and have been impressed with the product. I replaced my multivitamin with these beef liver capsules, and is now part of my daily stack. Most noticeable effect is the raise in energy levels. Capsules are easy to swallow. Shipping has been spot on. Glass bottles are used and come in a well packed box. No issues so far and will continue to use!

Big fan -- noticeable improvement in 2 weeks!

The title just about says it all. I wanted to add a high quality beef liver supplement to my life, for overall wellness. I take certain limited individual supplements such as Vit D+K, Vit C, Zinc--each separate with high quality sourcing and the best forms of each vitamin/mineral. Not a multivitamin fan...believe in only supplementing what your body tells you it needs, not just throwing a ton of stuff at it in hopes that it is a blanket fix. But beef liver felt like a great whole food source supplement that could function to help provide my body with anything it may be lacking in my diet--I eat well, but even the soil today isn't as rich as it was 100 years ago, so we just don't get all the goodies we think we could be getting from our food. To get to the point here... within two weeks of taking these MK beef liver supplements, an itchy skin rash that had plagued me on and off for almost 4 years (and nonstop for the past 8 months), cleared up completely. And a month later there is no sign it ever existed still. I am sold. Between the quality of the ingredients and the best value around (45 days in a bottle vs 30), I cannot recommend them highly enough. Buy them, and you'll probably notice positive changes before you finish the first bottle :) Whether in energy level or other aspects. Even if you don't notice a big shift (you may not if you're already feeling really good all the time), the nutritional boost is an excellent thing to do for your body.

Absolutely love this product

This has solved my problem of adding ***** meat to my diet. I have MS and the protocol I follow has this as a requirement. Also I am able to open them capsules and add the powder to my smoothies as I have trouble swallowing large pills...Win-win for me!!

High quality, so far so good

I've tried the Ancestral Supplements liver pills in the past and these seem identical (but cheaper). I can't say I've noticed any difference in my health yet, but my body tolerates them quite well (rare) and I plan to continue taking them. I enjoy supporting smaller businesses and MK Supplements has treated me very well. Thank you!

Liver for All

Knowing how nutritious liver is, we tried to eat it in various forms, especially now knowing the details of vitamin K2 and other nutrients. Never a fan however it is great to have a form that is easy to eat and has no after taste. That is what is important to us. Glad to say this is the situation with the beef Liver capsules. I am sure we will benefit in short order so will stick with them.
