Eating Raw Liver on a Carnivore Diet: Healthy or Dangerous?

Just a small portion exceeds your daily needs for key vitamins that support blood production, brain function, and detoxification [2].

Its high content of heme iron is especially beneficial for those prone to anemia, while its vitamin A content supports immune health, vision, and skin regeneration [3] [4].

When you consume liver raw, none of these nutrients are lost to heat, and this rich nutrient profile leads to various health benefits.

Proven Health Benefits of Raw Liver

• The liver can reverse deficiencies of common nutrients, including heme iron, B-12, and pre-formed vitamin A [5] [6].
• Liver supports hormones and fertility because its fat-soluble vitamins A, D, and K2 nourish endocrine function [7] [8].
• Liver can boost energy metabolism because its B-vitamin content acts as co-enzymes in cellular ATP production [9].
• Liver can improve skin, hair, and dental health because of fat-soluble vitamins and minerals [10].

Many people today are deficient in micronutrients like B-12, iron, and vitamin A, especially those following restrictive or plant-based diets.

Liver, especially raw, can refill nutrient stores quickly due to its bioavailability and increase energy levels, concentration, and mood stabilization.

Additionally, nutrients in liver help hormonal regulation, which is why some people report improved libido and more regular menstrual cycles after eating it.

The fat-soluble vitamin profile in liver also supports skin and dental health, as found by Dr. Weston A. Price, who documented the superior dental health of traditional societies consuming organ meats [11].

Despite these excellent health benefits, consuming ear liver can come with certain drawbacks.

Real Risks of Raw Liver You Must Consider

While raw liver is nutrient-rich, it’s also biologically active and prone to contamination. Bacteria such as Listeria or Campylobacter can survive even in cold storage and cause serious illness, especially in vulnerable individuals [12].

Parasites like Toxocara can also pose a risk, especially if the animal wasn’t raised in sanitary conditions.

Overdosing on vitamin A is another concern. Because the liver is so concentrated, eating large amounts frequently, especially raw, where nothing is decreased, can result in toxicity [13].

Symptoms may include nausea, joint pain, and, in extreme cases, liver damage. That’s why moderation and sourcing are critical if you choose to eat it raw.

So, Is Eating Raw Liver Safe?

Here’s the controversial part. While raw liver is undeniably nutritious, it can carry harmful bacteria and parasites.

Pathogens like Salmonella, E. coli, and Campylobacter may be present in raw meat, especially if the liver is not sourced and handled properly. These can cause food poisoning or more serious problems.

Some believe that buying from trusted sources, such as grass-fed, pasture-raised farms, reduces the risk of contamination. Freezing liver at sub-zero temperatures may also kill parasites, but not all bacteria.

So, eating raw liver carries inherent risk, and it's not advised for people with weak immune systems, pregnant women, or those unsure of the source.

If you want to try raw liver, you must follow the guidelines below to ensure it is safe to consume.

How to Eat Raw Liver More Safely

1. Choose 100% grass-fed/ pasture-raised from reputable farms.
2. Freeze the raw liver for 14 days at ≤ -18 °C because it helps kill most parasites (but bacteria survive).
3. Keep your consumption to ≤ 100 g per week to avoid vitamin A overload.
4. Handle liver sushi. Thaw it in the fridge, cut on a sterile board, and eat immediately.
5. When in doubt, sear. A quick 30-second per side sear kills bacteria while preserving much of the nutrient content.

If you choose to eat raw liver, proper sourcing and handling are essential. So, shop liver from healthy, grass-fed animals raised without hormones or antibiotics.

Is It Healthy to Freeze Liver?

Freezing liver at very low temperatures for at least two weeks can significantly reduce the risk of parasitic infection, although it doesn’t kill bacteria [14].

Keeping portions small also reduces the chance of toxicity. If you are unsure, lightly sear the liver to reduce the risk while preserving much of the nutritional value.

So, if you have decided to eat liver raw, you should know how it may taste!

What Does Liver Taste Like?

Beef liver has a rich, earthy, and slightly metallic taste. Some describe it as meaty with a mineral kick. The flavor is much more intense when raw, which can be unpleasant to beginners.

Chicken liver is usually milder and more palatable than beef liver.

Texture plays a big role, too. Raw liver is soft, slippery, and gelatinous. Many who eat it raw cut it into frozen cubes and swallow it whole to avoid the taste and texture.

If it is your first time eating liver, start with cooked chicken liver or pâté, and then slowly work your way up to beef liver or raw, because when you eat seared liver, you won’t lose many nutrients.

[cta-shop-products]

Raw vs. Cooked Liver: What Do You Really Lose?

Preserving nutrients is the biggest argument for eating liver raw. But cooking doesn’t remove everything.

Light searing maintains about 90% of water-soluble B-vitamins and makes the texture more palatable for many. Fully cooking does lower some nutrients, but also nearly eliminates microbial risks [15].

Choosing between nutrient preservation and safety is highly personal. If you value maximum nutrition and are confident in your sourcing and prep, you can choose raw liver [16].

However, if safety and taste matter more, you can choose seared or cooked liver, which has far fewer health risks.

Types of Liver

The following table shows the most common types of liver and their nutritional value:

Beef liver is the most popular type of liver, but many individuals also eat chicken livers. But are they really healthy or nutritious?

Are Chicken Livers Good for You?

Absolutely, but like beef liver, you shouldn’t overeat chicken liver. Too much vitamin A from liver can lead to hypervitaminosis A, a condition that causes fatigue, headaches, and liver damage [17].

As long as you’re eating liver once or twice a week in normal portions, it can be a healthy and beneficial part of your diet [18] [19].

Since these two types of liver are the most popular, let’s compare them and see which one can be a better option on a Carnivore Diet.

[cta-gocarnivore-plans]

Chicken Liver vs. Beef Liver: Which Is Better?

Both chicken liver and beef liver are nutritious, but they have different nutrient profiles. Beef liver is higher in vitamin A, B12, and copper, while chicken liver is milder in flavor and higher in folate and iron.

Chicken liver is generally the choice of those who find beef liver too strong or too rich. It is also more affordable and accessible.

In terms of safety, chicken liver is just as susceptible to bacterial contamination as beef liver, so you should apply the same precautions if you want to eat chicken liver raw.

From a Carnivore Diet standpoint, both livers are acceptable, but beef liver is considered the best due to its nutrient content. Having said that, we shouldn’t ignore the significant nutritional profile of chicken liver.

Chicken Liver Nutrition

A 100-gram serving of chicken liver contains [20] [21]:

• Vitamin A: ~330% of the RDA
• Folate: ~70% of the RDA
• Iron: ~50% of the RDA
• Vitamin B12: ~280% of the RDA

It’s also a good source of selenium, riboflavin (B2), niacin (B3), and protein, which support cell repair, metabolism, cognitive function, and red blood cell production.

Thanks to its iron and folate levels, chicken liver is especially beneficial for women of reproductive age or anyone with iron deficiency anemia. It’s also easier to digest for some people than beef liver.

However, if you're strictly following a Carnivore or nose-to-tail diet, beef liver is generally more common due to its superior vitamin A content.

Practical Ways to Try Raw Liver

• Swallowing frozen liver cubes is one of the most popular and least risky ways to begin. You get the benefits without the metallic taste or texture.
• Liver sashimi and blended shots are for more experienced or adventurous eaters who buy liver from trustworthy and clean sources.
• Monitor how you feel and look out for any digestive discomfort or symptoms of excess vitamin A, including nausea, vomiting, headache, dizziness, fatigue, dry or peeling skin, hair loss, and bone and joint pain. Adjust accordingly and don’t feel pressured to eat raw if it doesn’t sit well with you. Cooking is always a safer option.

Despite its significant health benefits and rich nutrient profile, some people should avoid raw liver completely. Let’s check out the list and see if you are among them.

Who Should Skip Raw Liver Altogether?

If you are among the following individuals, it is wise to avoid consuming raw liver [22]:

• Pregnant or breastfeeding women: The risk of foodborne illness and vitamin A toxicity can negatively impact fetal development.
• Anyone with a compromised immune system: They are more susceptible to infections, even from small traces of pathogens that a healthy person might handle without issue.
• Individuals with gout: The Liver is high in purines, which can increase uric acid and worsen gout.
• People on Accutane or other high-vitamin A medications
• Children under 5
• Those with type 2 diabetes and high cholesterol: Eating liver or other organ meats can increase the risk of fatty liver disease in these individuals.

If you fall into any of these categories, fully cooked liver or liver supplements are a safer alternative with many of the same benefits. But always take supplements after consulting a healthcare professional.

[cta-meal-plan]

Beef Liver Supplement Benefits

Beef liver supplements are freeze-dried and encapsulated forms of grass-fed beef liver, which provide most of the nutrients of raw liver without the risks.

The benefits of beef liver supplements include:

• Convenience and shelf-stability
• No need to cook or prepare
• Providing high levels of vitamin A, B12, and iron
• Safe and pasteurized (if made by reputable brands)

They’re especially helpful for people with nutrient deficiencies, fatigue, or anyone who can’t tolerate the texture or flavor of liver.

Conclusion

Raw liver is one of the most nutrient-dense foods on earth, but those nutrients can come with real microbial and vitamin-A risks.

If you’re healthy, buy grass-fed organs from reliable sources, handle them cleanly and properly, and keep portions small, raw liver can be a powerful nutrient source for you on a Carnivore Diet.

For everyone else, it is best to lightly cook liver or take capsules, which offer nearly the same benefits with far less danger.
