Organ meat, and especially liver, is one of the most nutrient-dense foods on the planet. Yet most of us don’t consume nearly enough of this nutritious powerhouse on a daily basis because of its image, its taste, or its lack of availability.

In this article, I’ll share the health benefits of liver. I’ll also provide a list of the best liver supplements from grass-fed and pasture-raised cows, as well as a simple recipe for liver pâté that I use to turn raw liver into something I enjoy eating several times a week.

Learn more about the benefits of eating organ meat, including their nutrient composition and the best organs to choose.

What Are Desiccated Liver Capsules?

Freeze-dried liver capsules
Desiccated means “dried out.”

In the context of liver supplements, the term “desiccated” simply means “dried out.” In other words, some manufacturers of beef liver supplements use a gentle freeze-drying method to turn raw liver into powdered gel capsules that are tasteless and easy to swallow.

Freeze-drying, as opposed to using high heat during the manufacturing process, ensures that most of the liver’s nutrients remain intact.

Nutrients in Liver

Liver is rich in heme iron.

Pound for pound, liver is arguably one of the most nutrient-dense foods available to us. While this article focuses on beef liver and beef liver supplements, you can obtain similar benefits from the livers of other animals, including chicken and ducks. In fact, I sometimes make liver pâté using chicken livers I find at Whole Foods.

Because liver has such a diverse micronutrient profile, it effectively provides the building blocks to support many functions in the body, including your metabolism, immune system, skin, eyes, reproductive organs, mental health and even your own liver.

Additionally, its synergistic combination of vitamins and minerals can naturally boost your energy levels by supporting your mitochondria, which is the part of every cell responsible for energy production.

But that’s not all. Liver is also an abundant source of essential B vitamins that can improve your brain function by fighting fatigue and brain fog and supporting other neurological processes.

Is Beef Liver Good for You?

Michael's Dinner - Beef liver and beef liver pate
My dinner plate the other day included pan-fried beef liver and homemade liver pâté.

As you can see in the list below, liver is an excellent source of vitamins and minerals. It’s also worth noting that liver is a great source of essential amino acids. In fact, most of the calories in raw liver stem from protein.

Despite the obvious benefits of eating liver, most people don’t recognize organ meat as the nutritional powerhouse that it is. I’d even bet that if you asked 100 nutritionists to name their top 10 superfoods, liver would likely not be among them. 

Instead, they’d probably mention primarily plant-based foods, such as kale, spinach, spirulina, chia seeds and some of the other usual suspects. While all of these plants have varying amounts of micronutrients, they also contain chemical compounds like antinutrients that bind minerals and prevent the body from absorbing them

Animals run away or fight, but plants use chemicals (and sometimes thorns) to defend themselves. That’s nature’s way of discouraging animals (including humans) from eating them.

Liver doesn’t have any antinutrients or any other inflammatory compounds that you could be sensitive or allergic to. The only downside to liver is that it has carbs in the form of glycogen (the storage vehicle of glucose and water). But I’d argue that the micronutrients in liver far outweigh the cons of consuming a few extra carbs.

Why Most People Don’t Eat (Enough) Liver

Cooked liver
If seasoned properly, liver can taste delicious.

Despite all the evidence that liver is a nutritional superfood, most people don’t eat liver on a regular basis — if they eat it at all. 

The likely culprit for that is the smell and taste of this organ meat. Honestly, I’m not a huge fan of how unseasoned, pan-fried beef liver tastes. Our four-year-old even left the room the other day when my wife fried liver to use in meatballs.

So I get it! However, looking back at my eating habits over the past four decades, I can name several foods that I once wouldn’t touch but now eat like the proverbial candy. 

So I encourage you to keep trying different ways of preparing liver and to get used to the taste. Personally, I’ve found two ways to truly enjoy liver: homemade pâté and meatballs. The latter even our six-year-old eats without hesitation.

Update: While writing this article, I’ve also started eating pan-fried liver with tons of camel fat* and seasoned with liberal amounts of salt and pepper.

If you haven’t yet found a liver recipe that you feel like you can handle on a regular basis, high-quality beef liver supplements may be the way to go.

I use them on a regular basis instead of vitamin pills, despite the fact that I eat a spoonful of pâté almost daily.

How Many Nutrients are in Liver Supplements?

Now that you know how nutritious beef liver is, the million-dollar question is this: How many of those nutrients are retained in freeze-dried beef liver capsules?

Three grams of freeze-dried liver — the standard dosage for liver supplements — contains the same micronutrients as 1 ounce of fresh beef liver.

It also has approximately 2 grams of protein (compared to about 7 grams in one ounce of fresh beef liver) and negligible amounts of fat and carbs.

How to Choose a Desiccated Liver Supplement

Below I’ll list some of the supplements that I’ve tried and recommend. But there are certainly other products on the market you could choose from. 

It’s important to keep in mind that supplements are largely unregulated in the United States. As a result, manufacturers have a lot of wiggle room regarding what information they put on the label and how accurately that information reflects the actual ingredients. That’s why I recommend sticking to brands you trust (see my recommendations below).

Here are the most important criteria that I look for when shopping for organ supplements.

Note: I recently launched my own beef liver supplement, which is included in the list below. My supplements are third-party tested and manufactured in a GMP-certified facility.

Grass-Fed and Pasture-Raised

Raw pastured beef liver
Raw pastured beef liver.

Much like when buying fresh meat, I make sure the organs that were used to make a supplement were sourced from grass-fed and pasture-raised animals. 

That’s not only important from an ethical perspective (it ensures sustainable farming practices), but also from a quality perspective, as it leads to a supplement with a better nutrient profile. 

For example, the liver (and muscle meat) of grass-fed beef has a more favorable fatty-acid composition than that of grain-fed beef. 

Additionally, you can find significantly more vitamin A (both provitamin A and preformed A) in the liver and muscle tissue of pasture-raised cows compared to grain-fed cows (as shown in this study). Those are only two of many examples that prove the superiority of pasture-raised vs. grain-fed meats.

Interestingly, New Zealand produces some of the best pasture-raised beef in the world — perhaps because most of the country’s beef herd is entirely grass-fed. 


Whatever product you choose, make sure it has sufficient amounts of liver (and thus, micronutrients). I recommend products with 3,000 milligrams of beef liver per serving or more.

Other Ingredients

I recommend avoiding products that contain unwanted ingredients like fillers, flow agents, artificial colors and sweeteners, sugars, soy, wheat, gluten, dairy and anything else you don’t recognize.

Processing Method

Many vitamins and minerals are heat-sensitive or quickly deteriorate when exposed to air. That’s why the processing method of a whole-food supplement is crucial. 

Freeze-drying is an excellent method to preserve as many micronutrients as possible. That’s why I recommend products that were manufactured using this method.

Third-Party Testing

I prefer products that have been tested to ensure ingredient quality and certain manufacturing standards. So look for ISO or GMP certifications, or ask for a test report if in doubt.

Below is a list of the five supplements we’ve used in the Kummer household. While there might be other brands that offer a similar ingredient quality, these are the ones I have tested and thus recommend.

MK Beef Liver Supplements

Why I decided to launch my own beef organ supplements brand.
Why I decided to launch my own beef organ supplements brand.

When I first wrote and published this roundup, I had no intention of launching my own line of beef organ supplements. I’ve tried and/or researched all of the supplements highlighted in this article and I have no hesitation about recommending them. They’re all high-quality products that can help you optimize your diet. 

But as I analyzed the specific details of the different options available in the marketplace, I started to realize they all fall short of my ideal standard in one area or another — whether that meant using high heat during production (which damages some of the liver’s nutrients) or being shipped in plastic bottles (which contain xenoestrogens that studies have shown can leach into the contents). 

I’m not the kind of person who likes making compromises when it comes to my health. So I decided to develop a supplement that better aligns with my lifestyle and meets my admittedly high standards.

Months of research and development led to what I sincerely believe is the best beef liver supplement on the market.

Ancestral Supplements Grass Fed Beef Liver

Ancestral Organ Supplements
Beef liver is one of many Ancestral Supplements I’ve used on a regular basis.

Ancestral Supplements nose-to-tail product line is always from grass-fed animals that were raised without the use of pesticides, hormones or antibiotics.

What I like about the company is that they produce in small batches but offer a variety of organ meats and beef “byproducts” you often won’t find anywhere else, including: heart, thyroid, pancreas, spleen, bone marrow, thymus, brain, kidney, trachea, prostate, adrenal, intestines, gallbladder, lung, colostrum, eyes and more.

In other words, the company is literally taking “nose-to-tail” eating to the next level — and I love it.

Ancestral Supplements’ beef liver is carefully processed (freeze-dried), non-defatted, and made from only the best and purest ingredients using cattle from New Zealand.

Enviromedica Pastured Beef Liver

Enviromedica pastured beef liver capsules
When I started supplementing with organ meats two years ago, Enviromedica’s beef liver was the first product I tried.

Enviromedica is at the top of my list of favorite supplement brands because of their unparalleled focus on ingredient quality and clean manufacturing practices. Enviromedica’s facilities are GMP compliant and ISO22716 certified. 

Sourced exclusively from grass-fed, pasture-raised, New Zealand bovine, Enviromedica’s beef liver is an abundant source of nutrients including protein, vitamin B6 and B12, folate, choline, copper, hyaluronic acid and a concentrated source of preformed vitamin A (retinol).

Additionally, all of their supplements are true-to-label. That means what’s on the label is exactly what’s inside, with no exceptions.

Aside from the trust I have in the brand and the positive experience I’ve had with some of Enviromedica’s other supplements, I like their beef liver tablets because they don’t contain anything but liver and gelatin (for the capsule). 

In other words, the product is free of dairy, wheat, yeast, gluten, corn, sugar, soy, shellfish, tree nuts, stearates, fillers, flow agents or any other potentially irritating ingredients.

And at $1.00 per serving, the supplement is also reasonably priced.

Enviromedica Pastured Organ Complex

Enviromedica 5 organ complex capsules
Taking just five capsules delivers a full serving of this organ complex.

Enviromedica Organ Complex is made from a mix of grass-fed liver, heart, kidney and pancreas, and delivers a rich source of vitamins, enzymes, minerals and other cofactors perfected by nature in their most bioavailable forms.

This supplement contains 1,500 milligrams of liver, 600 milligrams of kidney and heart, and 300 milligrams of pancreas. And I think it’s a great alternative to pure beef liver, especially if your goal is to improve your nose-to-tail eating habits.

Heart is a concentrated source of CoQ10 and B vitamins, and the kidney is rich in vitamin B12 and anti-inflammatory omega-3 fatty acids. It also has vitamin A, vitamin D and a variety of essential minerals to support blood flow, immunity, thyroid function, fertility and more. 

Meanwhile, the pancreas is a natural source of digestive enzymes, is rich in numerous essential minerals and vitamins, and provides both amino acids (the building blocks of protein) and nutrients to help with tissue repair and blood sugar regulation.

So if you want to take your “nose-to-tail” eating goals to the next level, check out this organ complex.

Equip Grass-Fed Beef Liver Capsules

Equip Grass-fed beef liver
Equip grass-fed beef liver.

Equip is the sister company of Perfect Keto and another one of the brands that I often purchase from. The company markets its beef liver capsules as a natural whole food alternative to multivitamin supplements, and that’s what it is. 

What I like about the product is its price tag. Unfortunately, as part of the research I conducted for making my own beef liver supplement, I discovered that Equip uses heat-dried liver rather than freeze-dried liver for its supplement. Heat drying can destroy some of the heat-sensitive micronutrients in liver, including vitamin C and B vitamins. 

As a result, I’d only opt for Equip’s product if none of the alternatives are available within your budget.

Detailed Nutrient Analysis of Beef Liver (Supplements)

Below is a list of most of the micronutrients you can find in liver (and liver supplements). All values are based on a one-ounce (28 gram) serving of raw liver.

Note that 28 grams of raw liver contains 19.8 grams of water. That’s why freeze-dried liver capsules have much less “volume” while offering similar amounts of micronutrients.

Vitamins in Liver

Liver is rich in retinol (the real Vitamin A)
Liver is rich in retinol (the real vitamin A).

The tables below give you an overview of the vitamins, minerals and co-factors found in liver. I’ll go into more detail about the nutrients that occur in higher amounts.

Keep in mind that the numbers below are based on a serving size of only one ounce. So you need very little of this nutritional powerhouse to fulfill your daily requirements of many micronutrients. 

VitaminsAmount% DV
Betaine1.2 mgN/A
Choline93.3 mgN/A
Vitamin A (Retinol)4,732 IU (1,385 IU)95%
Vitamin B1 (Thiamin)0.1 mg4%
Vitamin B2 (Riboflavin)0.8 mg45%
Vitamin B3 (Niacin)3.7 mg18%
Vitamin B5 (Pantothenic Acid)2.0 mg20%
Vitamin B6 (Pyridoxine)0.3 mg15%
Vitamin B9 (Folate)81.2 mcg20%
Vitamin B12 (Cobalamin)16.6 mcg277%
Vitamin C0.4 mg1%
Vitamin D4.5 IU1%
Vitamin E (Alpha Tocopherol)0.1 mg1%
Vitamin K0.9 mcgN/A

Betaine: Betaine protects cells, proteins and enzymes from environmental stress (e.g., low water, high salinity or extreme temperature). It also plays an important role in liver metabolism and can reduce the risk of developing metabolic diseases.

Choline: Choline plays an important role in numerous bodily functions, including metabolism and cellular growth. Choline is an essential nutrient; while the body can make some of it the majority must come from dietary sources.

Vitamin A and retinol (95% DV): Vitamin A is a fat-soluble vitamin that exists in different versions, including retinol (preformed vitamin A) and beta-carotene (provitamin A). The former is only found in animal sources (such as liver) and is much better absorbed than beta-carotene, which the body has to convert into retinol before it can be utilized.

Almost 30% of the vitamin A in bovine liver is retinol.

Vitamin B2 (45% DV): Riboflavin is one of the eight B vitamins and is responsible for cellular respiration (mitochondria), breaking down food components, absorbing nutrients and maintaining tissue.

Vitamin B3 (18% DV): Niacin is used by the body to turn food into energy. It also supports the body in maintaining the health of the nervous system, the digestive system and the skin.

Vitamin B5 (20% DV): Pantothenic acid is necessary for making blood cells, as well as for synthesizing coenzyme A — an important factor in fatty acid metabolism.

Vitamin B6 (15% DV): Pyridoxine is an important player involved in brain development and keeping the nervous and immune systems healthy.

Vitamin B9 (20% DV): Folate (also called folic acid) plays an important role in the creation of oxygen-carrying red blood cells. A deficiency in this essential vitamin can lead to anemia (low red blood cell count). Pregnant women often get folic acid supplements prescribed to ensure proper red blood cell counts as the body makes more blood to support the growth of the baby and to reduce the risk of birth defects.

Vitamin B12 (277% DV): Cobalamin plays an important role in red blood cell formation, cell metabolism, nerve function and the production of DNA, according to the Mayo Clinic. Vitamin B12 deficiency, if left untreated, can lead to anemia, fatigue, muscle weakness, intestinal problems, nerve damage and mood disturbances. 

Vitamin B12 is most prevalent in animal foods, which is why vitamin B12 deficiency is most prevalent among those who follow a pure plant-based diet (i.e., vegans and vegetarians).

Minerals in Liver

Liver is rich in copper and other minerals.
Liver is rich in copper and other essential minerals.
MineralsAmount% DV
Calcium1.4 mg0%
Copper2.7 mg137%
Fluoride11.1 mcg16%
Iron1.4 mg8%
Magnesium5.0 mg1%
Manganese0.1 mg4%
Phosphorus108 mg11%
Potassium87.6 mg3%
Sodium19.3 mg1%
Zinc1.1 mg7%

Copper (137% DV): Copper is an essential trace mineral and plays an important role in making red blood cells, as well as in supporting both nerve cells and the immune system. It helps the body form collagen to support skin, joint, hair and nail tissue, and it plays a role in energy production.

Fluoride (16% DV): Fluoride is an important mineral in your bones and teeth. Specifically, fluoride helps with the formation of teeth and bones and in maintaining their structural integrity. But note that a study found that too much of it can increase your risk of bone fractures.

Iron (8% DV): Liver is one of the best sources of heme iron, a type of iron that is predominantly found in the bodies of humans and animals (more than 95% of the functional iron in the human body is heme). Heme iron is exceptionally well absorbed and thus much more bioavailable than the non-heme iron found in plants.

Phosphorus (11% DV): Phosphorus is the second most abundant mineral in the human body (calcium is number one) and is present in every cell, as well as in bones and teeth. It also plays an important role in carbohydrate and fat metabolism, and is needed to make proteins for cell growth, cell maintenance, and cell repair.

Zinc (7% DV): Zinc is one of the most important nutrients when it comes to supporting the body’s defenses and immune functions. It also plays a role in cell division, cell growth, wound healing and carbohydrate metabolism. You also need zinc to smell and taste. In other words, these senses wouldn’t work correctly without the involvement of zinc. 

Macros and Other Functional Nutrients

Besides vitamins and minerals, a one-ounce serving of liver provides the following functional nutrients:

Coenzyme Q10 (1 milligram): Organ meats are one of the most abundant sources of CoQ10, a micronutrient that helps generate energy in your cells. While your body can make its own CoQ10, production usually slows down as you age. Coincidentally, some metabolic diseases, such as brain disorders, diabetes and cancer, have been linked to low levels of CoQ10.

Carbohydrates (1.1 grams): Red meat is normally not a source of carbs, but liver is different because it stores glucose (sugar) in the form of glycogen. When a cow is butchered, all the glycogen in its muscle tissue gets released. That’s why you won’t find any carbs in a piece of steak. However, the liver retains all of its glycogen.

Protein (5.7 grams): Protein is one of the two essential macronutrients (fat is the other) humans need to get from food. The amino acids of liver protein help the body create and repair muscle tissue, make collagen and support the body’s immune function.

Frequently Asked Questions

Liver has greater amounts of certain nutrients than the daily recommended value. Is that a problem?

Beef liver has ample amounts of cholesterol, certain minerals, and fat-soluble vitamins (such as vitamin A) that can become toxic if ingested in excess amounts.

While it’s true that, in theory, you can have too much of these nutrients, I don’t see that as being an issue in real life. I don’t know anybody who consumes large amounts of liver every single day.

Doing so would also not mimic the eating habits of our ancestors, because they didn’t have access to fresh liver every day. Plus, they would have shared every “kill” among a tribe of up to 40 members. 

Based on the scientific evidence that I’ve found, it’s perfectly safe to consume between four and eight ounces of liver per week.

Also, dietary cholesterol is not unhealthy and has no impact on blood cholesterol levels. I’ve said that numerous times before on this blog (here and here), but I feel like it’s worth repeating.

Why are none of the recommended brands labeled as organic?

100% pasture-raised and grass-fed cows that don’t receive any non-organic or GMO feed are, by definition, organic. I’ve found only one brand (Grassland) that carried the “organic” label, but that referred to the kelp in the product, not the liver.

What is defatted liver?

Defatting a liver means removing its fat, and with that fat many of the fat-soluble vitamins. That’s why it’s important to choose beef liver supplements that contain non-defatted liver. All of the recommended products above fall into this category.

Considering that some supplement manufacturers make it a point to mention that the livers they used are un-defatted, it’s reasonable to assume that others use de-fatted livers. Why someone would want to remove fat from the liver before freeze-drying it is beyond me. Maybe to satisfy those consumers who are still riding the “low-fat” train!?

Where does the gelatin of some of the capsules come from?

Gelatin is a protein (similar to collagen) that’s made from boiling skin, tendons, ligaments and/or bones. Most gelatin capsules are made from bovine gelatin.

Can I cook or bake with beef liver powder?

At least one of the brands* I stumbled across while writing this article also offers beef liver powder, meant for mixing into shakes, cooking or baking. While making a smoothie or shake with desiccated beef liver powder is perfectly fine, I wouldn’t recommend heating it to avoid destroying the heat-sensitive micronutrients.

Can I use beef liver supplements instead of eating liver?

The best source of nutrients is fresh food. In the case of animal products, that means unprocessed liver sourced from grass-fed, pasture-raised and grass-finished cattle. 

However, if you follow a healthy dietary lifestyle, rich in healthy fats and low in carbs (especially processed carbs), adding organ meats in the form of supplements is your second-best option.

I eat organ meats but probably not as much as I could. That’s why I supplement with beef liver and organ meat pills.

Where can you buy fresh beef liver?

We buy a whole pasture-raised cow every year from a local farmer, and that’s how we get our liver. We also buy organic chicken livers at Whole Foods. 

If you want to buy liver online, I recommend checking out White Oak Pastures. They offer a wide variety of different organ meats from grass-fed cows. We often buy their liver, heart, suet and other organs.

Is eating liver good for liver health?

Absolutely! Organs are usually excellent sources of the nutrients those organs need to thrive. So eating liver supports your liver, eating heart is good for heart health, etc.

Is eating beef liver paleo?

Eating nose-to-tail is arguably the most paleolithic way of eating. So yes, liver is definitely paleo!

Do I still need to eat veggies if I consume a lot of organ meat?

If you regularly consume sufficient amounts of organ meat, including liver, you’ll get all the nutrients your body requires. So there’s no need to worry about your veggie intake, in my opinion.

More important than getting the required amount of vital nutrients is getting the right and most-usable nutrients. 

Organ meats contain heme iron and retinol (aka the real vitamin A). Plants contain the inferior non-heme iron and beta-carotene (a precursor to vitamin A). Both are examples of nutrients found in plants that the body can’t absorb and use as well as their animal-based counterparts.

I’m not recommending avoiding seasonal fruits and certain veggies (I eat them), but I remain unconvinced as to their importance in the context of human evolution. You can learn more about the differences of meat vs. plants in this article.

Is Liver High in Tyramine?

Certain foods, such as aged cheese and (aged) liver, contain relatively high levels of tyramine, an amino acid that can cause migraines and high blood pressure in some people. 

The issue is often exacerbated in people who are on certain antidepressants, such as monoamine oxidase inhibitors (MAOIs). Monoamine oxidase is an enzyme that breaks down excess tyramine in the body. If that process is inhibited by medication, you might end up with elevated levels of tyramine (leading to high blood pressure and migraines).

The good news is that, based on the latest scientific evidence, fresh or freeze-dried liver has relatively low levels of tyramine. Only aged liver has been shown to have high enough levels of tyramine to cause issues and interact negatively with MAOIs.

However, to be on the safe side, if you are taking MAOIs, we recommend having a discussion with a knowledgeable healthcare professional before consuming liver supplements.


Michael uses beef liver supplements
I take beef liver capsules several times a week.

Organ meats have been an essential part of human nutrition for millions of years. Unfortunately, the combination of our modern lifestyles and the industrialization of food has removed these nutritional powerhouses from the plates of most people. 

The results of our modern eating habits are a dramatic increase in metabolic disease and obesity rates, as well as widespread deficiencies of essential vitamins and minerals. So it’s time to reverse that course and to start nourishing our bodies with the foods we are genetically primed to consume.

While I highly recommend trying to get pasture-raised organ meat (including liver) back on the dinner table, I also understand that this isn’t as easy for everyone as I might make it sound. 

At the Kummer household, we started including liver in our diet a few years ago. But we still don’t consume the variety and amount of organ meat that we should.

That’s why I believe including the right supplements on top of a solid dietary framework — even if that doesn’t yet include the regular consumption of organ meat — is an excellent idea.

55 thoughts on “Best Beef Liver Supplements”

    • Hi Shree,

      one serving of MK Supplements Grass-Fed Beef Liver has about 20% DV of folate (Vitamin B9). Depending on your diet, you might need some more and I’d recommend checking with your OBGYN how much folate (not the synthetic folic acid) you need.


    • Hi Rewa,

      If you’re an adult, you can take 3 grams as well (that’s 4 – 6 capsules, depending on the manufacturer). My wife weighs 110 lb and takes 4 capsules of my supplement (that’s 3 grams of liver).


        • Hi Jolene,

          yes, my wife takes it daily and so do our kids. Consuming organ meats (fresh or freeze-dried) on a daily basis is perfectly safe, unless you suffer from a preexisting condition that would prevent you from metabolizing some of the vitamins or minerals in liver.


  1. Thanks for the article and the suggestions. I really appreciate you coming out with glass bottles instead of plastic!

    You mentioned a concern in the processing of liver, that heat drying is worse than freeze-drying because the liver loses some of its nutrients but also that eating fresh liver is the best option. Wouldn’t cooking liver at home also affect its nutrients? So why would heat-drying be worse? Trying to understand the scientific difference between cooking at home, freeze-dried liver pills and heat-dried pills.

    • Hey Ian,

      yeah, cooking liver will also degrade some of the heat-sensitive micronutrients. That’s why I fry only the outside and leave the inside as pink as possible when I make pate at home.

      To get the most nutrients out of the liver, you’d have to eat it raw as I did during the last Thanksgiving dinner :)

      But there is obviously a risk of food-borne pathogens by doing so. That’s why I pop one or two capsules even on days where I eat cooked liver.


  2. I see a lot of claims but almost no peer reviewed scientific studies. I think there’s probably a net benefit in most cases, but how can you really be sure if you don’t have experimental data to back it up. I think it is best to consult with your doctor before taking this supplement.

    • Consult a doctor? Why? So he can steer you toward big pharma products that instead of supporting and healing you at the cellular level actually just mask your symptoms, toxify your body and cause chronic illness and disease?
      Wake up, bro.
      Big pharma medicine is a for-profit, turn-key operation that doesn’t take your long-term well-being into account.

  3. Is there a chicken liver supplement or something? I’d like my family to start eating more liver but they don’t eat beef so I’m not sure what to do at this point.

  4. Thanks for the informative article! We have been buying Ancestral Supplements and I’m pleased to see it on your list. I noticed you say you take 1 capsule (of one of the above products) per day. Ancestral’s dose is 6. I’m a smaller woman, so I decided I’d take less because I’d eat a smaller serving if I were eating it on my plate AND I dont take it every day, because I wouldn’t eat liver every day. My question is, based on your research, does that make sense to you? Does it make sense to take the supplements a few times per week rather than every day? And maybe a smaller quantity if you aren’t a 180# male? Thanks

    • Hi Anne,

      where in the article do I say to take only 1 capsule a day? I couldn’t find it but if I say so, it’s a typo :)

      I eat an ounce or so of liver (fresh or freeze-dried) almost every day but also try to mix it up with other organ meats (from Ancestral Supplements). I’d try to eat small amounts of liver several times (3-4x) a week and then mix in other organs.


  5. Great info. Since e coli can survive freezing temps, do you know if it is possible for e coli to survive in the freeze dried liver powder supplements?

    • Hi Ann,

      Yes, that’s possible but highly unlikely. Plus, the livers are usually tested for common pathogens before being processed. So I don’t think you should be concerned about an E.coli contamination in liver supplements.


  6. Hello, and thank you for your article. I have some questions ….mostly about the amount of fresh liver and nutrients per serving of the 6 liver capsules. If the liver loses average of two thirds of its weight during the drying process……6 capsules equaling 3 grams of dry weight….would mean that each serving would be equivalent to 15 grams of fresh weight. My question is …How does this equate to the nutrients being equal to 1 ounce of fresh liver….ie 1 ounce is 28.3495 grams. I have reached out to Ancestral Supplements about this….great company, Brian very approachable and willing to answer questions. But he told me the same thing……one serving ..(6 capsules, weight 3grams is equal to the nutrients in 1 ounce of fresh liver……they measure by nutrient content)…..this makes no sense to me. 15 grams of freah liver cannot contain the same amount of nutrients as 28 grams.
    I have actually dried some liver and weighed it before and after and it does actually lose roughly two thirds of its weight…….If you know of any answers to this I would very much like your opinion….I think it is an important point because of the amount of vitamin A in liver

    • Sorry….I meant ..every serving of 6 capsules consisting 3 grams dry weight liver would equal 9 grams fresh liver . Not 15 grams fresh liver as I mentioned above

      • Hi Candi,

        one ounce of fresh liver has about 6 grams of protein, 1 gram of carbs and 1 gram of fat. So assuming none of the macronutrients are lost during the freeze-drying process, the capsules should have about 8 grams (and not 3).

        So yeah, good question and it doesn’t make any sense. I’ll try to find out more!


        • Thankyou…..this issue has been been realy bugging me. I’ve been low on iron and want to use the liver caps to try and correct that but I don’t want to either overdo or underdo it

          • Here is the explanation from Ancestral Supplements: When freeze-drying the macronutrients are also concentrated. The Carbon, Hydrogen and Oxygen molecules in carbohydrates and fats for example bond closer together and some of the hydrogen and oxygen are dried out. The micronutrients stay mostly intact and that’s why we say 1 ounce of fresh liver is equivalent to 6 capsules of our organs supplements.

  7. Thank you for writing this all out. I have been dealing with low Vitamin B12 levels the last year and my general doctor told me to start taking B12 supplements. Shortly after taking B12 (methylcobalamin) supplements, my arms broke out with pretty nasty acne that wouldn’t clear, and this also ended up on my chest and stomach (in smaller quantities). I believe that this was caused by the supplement, but haven’t been able to prove it. My question to you would be if you thought a Beef Liver supplement would cause similar reaction? Does my body process it differently than it would a B12 supplement? I’ve been trying to find a solution, because taking the B12 supplements did help in many other ways, but the breakouts on my arms were too much to continue taking them.

    • Hi Jason,

      generally speaking, your body absorbs micronutrients from real food better and more efficiently than from synthetic sources. I have never heard about issues with Vitamin B12 from liver (freeze-dried or fresh), so I’d definitely give that a try.


  8. Hi Michael,
    Thanks for the great info. The discount code for Enviromedica Beef Liver has expired. Do you have a new one?

      • The energy boost of Grass fed organic Beef liver capsules is incredible. I have just started taking them and the boost in energy you get is like nothing I have ever experienced. Also, how much K2 is in there, because correct me if I am wrong, K2 moves the calcium out of the arteries into the bones. Very good for heart health and bones?

        • Hi Bert,

          one ounce of beef liver (or 3 grams of freeze-dried liver) has approximately 3-4 mg of K2 which helps get calcium into bones and teeth, among other benefits!


  9. I’ve been severely anemic and also have a copper deficiency. Infusions haven’t helped and I want to have a baby. Trying anything I can except I can’t eat liver. Just ordered the supplements. Think it’ll
    Help increase rbc and deficiencies?!

  10. This article was exactly what I was looking for, lots of helpful information! I’m convalescing from a nasty bout of Covid, and am looking for ways to support my body and regain some much needed energy. I’m thinking organ meats would be effective. It’s so important to me to trust the companies I buy animal products from. Thanks so much for sharing your findings.

  11. Hi Michael,

    I have a question about dosage. On the packing on Ancestral it is recommended to take at least 6 pills per day or what is suggested by a healthcare provider. What is your suggestion? I’ve read from previous people who consume 3 pills per day.

    Thank you!

  12. what are your thoughts on daily vitamin supplements and liver supplements in the same day. I was thinking if i start to take a liver supplement skipping some of the other ones that i would normally take that day? then on the days i dont take the liver i’d take my normal regimen of daily vitamins?

  13. If I eat zero liver per week, how often should I supplement? Many of those brands suggest daily but, like you mentioned, that might be a little much and not in line with ancestral patterns.

    • Hi Leroi,

      I think taking a 3g serving every day is just fine. In fact, that’s what I do on days where I don’t eat liver. It’s not in line with ancestral eating habits but neither is having regular meals :) So I wouldn’t overthink it. What I mean by that is to have a serving every day while supplies last. When you travel or go on vacation, don’t bring the supps and don’t worry about stocking enough for a continuous supply. I use them when I have them and don’t when I don’t.


  14. Great article. Can I ask why perfect supplements didn’t make the list? They first introduced me to desiccated liver, even before I changed my eating habits, and it definitely improved my health and energy. Now I am interested in other brands that carry different organs as well, but I have always been happy with perfect supplements. Plus if you buy a bunch at once, you can’t beat the price.

    • Hi Casie,

      mostly because I didn’t know about that brand when I wrote the article and I never tried their products :) But I mentioned their liver powder in the FAQ. From what I can tell, their product is a perfectly fine choice!

  15. Great article man. Ive been eating liver regularly for the past year. Beef liver is my least favourite in taste, lamb liver is much better and chicken liver is delicious. Im gonna assume chicken liver is not as nutrient/mineral dense as the former two though… I’ve also had kidneys a few times and even a lambs brain curry!

    I am travelling a lot at the moment and finding it hard to source and work organ meats into the diet, so I will be buying supplements. I have few questions though.

    1. If I eat real liver once in the week, do I still need to supplement that week as well? If so how much?
    2. Should I be considering both liver supplement and other organ supplements alongside it to? I also take bone broth drink everyday. I don’t want to overdo it.
    3. If no organ meat is consumed in the week I am assuming I should take organ meat supplements everyday?

    Thanks again for this beaut article

    • Hi Hank,

      1) It depends on the amount of liver you eat. Liver has a lot of fat-soluble vitamins that can be toxic if consumed in larger amounts. So if you eat a couple of ounces a liver once a week, I wouldn’t worry about liver supplements on the remaining days.
      2) I’d definitely considering eating other organs as well. But if that isn’t an option, I’d use supplements. That’s what I do because I find it harder to source kidneys, heart, pancreas…than liver.
      3) That’s what I do.


    • Hi Steve,

      I’m not a medical doctor and I don’t know the details of your bloodwork. However, I can tell you that elevated LDL is not an issue for most people if you eat well (high fat, low carb, no seed oils). My LDL is elevated too and I take the MOFO supplements.


    • Hi Patrick,

      you can take liver supps anytime, with or without a meal. Just be aware that liver supplements break your fast because they contain protein, fat and carbs. So if you fast intermittently, take them after breaking your fast.

  16. Great article. After reading I was inspired to begin utilizing a liver supplement since the presence of liver has been non-existent in my diet for the majority of my life.
