Why Liver and Kelp?

Why Liver and Kelp? 

“Something in the liver had prevented them from becoming exhausted.”

“To this day scientists have not been able to pin a label on this anti-fatigue factor.”

The Liver Files

The anti-fatigue factor was described by Benjamin K. Ershoff, PhD, in July 1951…..

Anti : reversing or undoing

Fatigue : a reduction in the efficiency of a muscle or organ after prolonged activity

Ershoff divided laboratory rats into three groups. The first ate a basic diet, fortified with 11 vitamins. The second ate the same diet, along with an additional supply of vitamin B complex. The third ate the original diet, but instead of vitamin B complex received 10 percent of rations as powdered liver.

After several weeks, the animals were placed one by one into a drum of cold water from which they could not climb out. They literally were forced to sink or swim. Rats in the first group swam for an average 13.3 minutes before giving up. The second group, which had the added fortifications of B vitamins, swam for an average of 13.4 minutes.

Of the last group of rats, the ones receiving liver, three swam for 63, 83 and 87 minutes. The other nine rats in this group were still swimming vigorously at the end of two hours when the test was terminated. Something in the liver had prevented them from becoming exhausted. To this day scientists have not been able to pin a label on this anti-fatigue factor.

How Vince Gironda Found the Power of Food

Vince Gironda
The Iron Guru Vince Gironda  (1917 to 1997)

One man who had mastered dieting and who never used drugs was the Iron Guru Vince Gironda.

Gironda began competing in the 1950s and then trained both athletes and movie stars for many decades after. So defined was his physique, he often found himself penalized by judges who seemed confused over his appearance.They thought that this type of cut-up physique was slightly repugnant so he lost most muscular titles to smoother men who had that type of definition for that day.

Gironda often stated that nutrition was 85-90 percent of bodybuilding. His alternative to drugs was eggs, he advocated up to 36 eggs a day for 6 to 8 weeks to produce muscle buildup.

He recommended mineral rich sea kelp for its iodine content and dried liver extract for blood building and oxygen capacity boosting. Many bodybuilders used desiccated liver after the early 1950s experiments of Dr. Benjamin Ershoff. Ershoff who conducted the famous liver study wherein rats fed 10 percent desiccated liver swam far longer compared to controls.

Vince Gironda’s 3 Natural Anabolic Secrets

 Anabolic : the synthesis of complex molecules (f.ex muscle tissue) in living organisms


Vince used to suggest taking three to four amino acid tablets and 3 to 10 liver tablets every three hours to help keep the body in a positive nitrogen state between meals and during those times when a person can’t eat a normal meal or snack.

Liver contains a red protein pigment called Cytrochrome P-450 which accounts for the endurance factors that many hard training bodybuilders receive from taking it. Back in the 60’s, 70’s and 80’s it was common to see many bodybuilding competitors take as many as 60 Liver tablets a day in the off-season and 100 tablets the last few weeks prior to a competition.

Recognized the world over as a superfood…

 Superfood : a nutrient-rich food considered to be especially beneficial for health and well-being.

Because mother’s milk is low in iron, liver is a valuable first food for baby, as around six months a full-term baby’s iron stores begin to decrease. In many traditional cultures, pre-chewed liver is a common first food. It is no wonder this food is revered for its nutritional gifts—compared to other foods, it outdoes most others in terms of vitamin and mineral concentration (see chart below).

Feed Your Mind: The Power of Whole Food Nutrition in Boosting Mental Wellbeing

Feed Your Mind The Power of Whole Food beef organ and kelp Nutrition in Boosting Mental Wellbeing

It is Mental Health Month, and we love to talk about mental health and wellbeing as we understand its importance to our quality of life. While we often think of mental health as a complex tangle of emotions and experiences, there’s a surprising connection between our gut and our brain. 

This Mental Health Month, we’re exploring how Grassland Nutrition’s freeze-dried wholefood beef organs and kelp can be a game-changer for your overall wellbeing, including dopamine production, thanks to the rich B12 and iodine content.

The Gut-Brain Connection

Recent scientific research has unveiled the intimate connection between our gut and our brain. This relationship is often referred to as the “gut-brain axis.” It turns out that the health of our gut microbiome – the trillions of microorganisms living in our intestines – can significantly influence our mental health.

A balanced gut microbiome can:

  1. Boost Mood: The gut produces many neurotransmitters, including serotonin and dopamine, which play a crucial role in regulating our mood and emotions. An imbalanced gut can lead to mood swings and even depression….
  2. Reduce Anxiety: The gut-brain axis influences the stress response, and an unhealthy gut can lead to heightened anxiety levels.
  3. Enhance Cognitive Function: A healthy gut can improve cognitive functions such as memory and focus.
  4. Support Better Sleep: Gut health impacts sleep patterns, so addressing gut issues can lead to more restful nights.

The Role of Grassland Nutrition Products

Grassland Nutrition offers a unique solution to promote both gut and mental health through their freeze-dried wholefood beef organs and kelp products. Here’s how these superfoods can benefit you:

  1. Beef Organs for Optimal Nutrition: Grassland Nutrition’s freeze-dried beef organs are a treasure trove of essential nutrients. They’re packed with B12, which is essential for brain health and dopamine production. B12 deficiencies are known to cause mood disorders and cognitive decline. By incorporating these nutrient-rich organs into your diet, you’re giving your brain the fuel it needs to function at its best.
  2. Kelp’s Iodine Power: Iodine is another critical nutrient for mental health. Kelp, a type of seaweed, is a fantastic source of iodine. Iodine deficiency can lead to thyroid issues, which are linked to mood imbalances. Adding kelp to your diet helps maintain proper thyroid function, which in turn supports a healthier mind.
  3. Gut Healing: Both beef organs and kelp contribute to gut health. The nutrients they provide support the growth of beneficial gut bacteria, helping to maintain a balanced gut microbiome. A healthier gut means better digestion and absorption of nutrients, which can positively impact your mental health.

Incorporating Grassland Nutrition into Your Diet

It’s easy to integrate Grassland Nutrition’s products into your daily routine. You can sprinkle freeze-dried beef organs onto savoury foods, mix them into smoothies, or enjoy them as a snack. Kelp can be added to soups, stews, or as a seasoning for a nutrient-packed boost.

This Mental Health Month, take a step towards better mental and gut health by exploring the incredible benefits of Grassland Nutrition’s freeze-dried wholefood beef organs and kelp. 

Nourishing your body from the inside out can make a significant difference in how you feel and think, ultimately leading to a happier and healthier you. 

Remember, a healthy gut is a happy mind!

How Beef Organs Can Supercharge Your Mind and Shield Against Dementia

In the quest for a long and healthy life, protecting our cognitive abilities is crucial. Dementia, a decline in cognitive function affects everyday life and is a condition feared by many. Every year, there are nearly 10 million new cases (1)

While genetics play a role in our susceptibility to dementia, lifestyle factors including diet, can also influence our mental and cognitive wellbeing. 

In this blog, we’ll explore the potential benefits of incorporating beef organs into your diet as a preventive measure against dementia.

Understanding Dementia

Dementia encompasses various conditions that result in cognitive impairment, with Alzheimer’s disease being the most common form. Symptoms may include memory loss, difficulty in problem-solving, and changes in behaviour, which can significantly impact an individual’s overall welfare.

The Role of Diet in Brain Health

Research suggests that diet plays a crucial role in brain health and may help reduce the risk of dementia. Consuming nutrient-dense foods can nourish the brain, support cognitive function, and potentially delay or mitigate the onset of dementia-related symptoms.

Beef Organs: A Nutritional Powerhouse

Beef organs, such as liver, have long been celebrated for their exceptional nutritional value. These organs are rich in essential nutrients that are beneficial for brain health:

Vitamin B12 Beef organs, particularly liver, are an excellent source of vitamin B12, a vital nutrient for brain function. A deficiency in vitamin B12 has been linked to cognitive decline and dementia.

Omega-3 Fatty Acids Brain health thrives on omega-3 fatty acids, and beef organs are a source of these essential fats. Omega-3s are known for their anti-inflammatory properties and support of cognitive function.

Choline Beef liver is a top source of choline, a nutrient essential for the production of acetylcholine, a neurotransmitter involved in memory and learning.

Antioxidants Beef organs also contain antioxidants like selenium and vitamin E, which help protect brain cells from oxidative damage.

Add Beef Organs to Your Diet

Here’s some practical ways to incorporate them into your diet:

Classic Danish-Style Liver Pâté: 

Liver pâté is a delicious way to enjoy the nutritional benefits of beef liver. Spread it on toast for a satisfying snack or eat it in its beautiful naked baked state.

Danish-style Beef Burgers with cheese and beef liver cream sauce

Whole food beef organ supplements: If you’re not a fan of organ meats, consider high-quality supplements that provide the essential nutrients found in beef organs. 

Slow-Cooked Stews: Add beef organs to slow-cooked stews or soups, allowing the flavours to meld together.

As we mark Dementia Action Week (2), let’s remember that a proactive approach to brain health can make a world of difference. Embrace a diet enriched with beef organs, soak in the morning sun for that essential DHA boost, engage in regular exercise, and indulge in mind-stimulating activities like reading and problem-solving puzzles. Together, these steps can help safeguard your cognitive wellbeing and contribute to a brighter, healthier future. Let’s act now, because a dementia-friendly world begins with our actions today.

If you have a loved one with Dementia and are seeking practical caring support we urge you to look at the services provided by Dementia Doulas International (3), a professional compassionate care approach that supports families and those impacted by advancing dementia, to prepare them for what’s to come so that everyone can come back to living for today. Check out the series of Dementia experience books by Wendy Hall of Dementia Doulas International to help you navigate and best support those needing help – at all stages.

Beef Organ Supplements: Your Personalised Path to Optimal Health!

As we are becoming increasingly health-conscious and discerning about what we consume for the betterment of our health, individuals are seeking ways to enhance their wellbeing through balanced nutrition and dietary supplementation. 

The consumption of beef organ wholefood supplements in capsule or powder form is thankfully now back on the rise after becoming out of favour across the last decade, yet some of us in Western society recall how these were a regular feature of everyday meals (liver and onions, beef and kidney pie…) when we were ‘knee high to a grasshopper.’ 

These supplements offer a concentrated source of essential nutrients found in organ meats, promoting overall health and vitality. However, determining the right amount of supplementation can be perplexing. In this blog, we will explore a personalised approach to using beef organ wholefood supplements to maximise their benefits and support individual requirements.

The Power of Beef Organ Wholefood Supplements

Beef organ wholefood supplements have gained popularity due to their rich nutrient content. These supplements include organs such as liver, heart, and kidney, which are nutritional powerhouses. Organ meats are packed with vitamins, minerals, proteins, and healthy fats that can significantly contribute to various aspects of our health, including energy levels, immune function, and overall wellbeing.

Understanding Individual Requirements

Before starting any supplement routine, it’s pertinent to understand that everyone’s nutritional needs differ.  This is based on numerous factors such as age, sex, lifestyle, and underlying health conditions. While some individuals may have nutrient deficiencies that warrant higher doses, others may only require maintenance-level supplementation.

Starting with 3 Capsules: A Gradual Approach

For those opting for beef organ wholefood supplements in capsule form, we recommend starting with three capsules per day. This allows your body to acclimate to the new supplement and ensures you don’t overwhelm your system with an excessive intake of nutrients all at once. Over the course of two weeks, monitor how your body is responding to this initial serving.

Gradually Increase to 6 Capsules

After the initial period of three capsules per day, you may gradually increase your intake to six capsules daily. This step provides a higher concentration of nutrients, which can be particularly beneficial for individuals with specific health concerns or those with nutrient deficiencies. Pay close attention to your body during this phase. Look for signals it may send, and reduce if there are any unwanted effects. In the vast majority of individuals a rise in energy levels and vitality will be experienced 

Finding Your Optimal Maintenance Level

Once you’ve reached the stage of six capsules per day, you may begin to assess how your body responds to this level of supplementation. Some individuals may find that they achieve their desired health goals and maintain optimal wellbeing with this dosage. If you feel good and experience positive effects, you may continue with six capsules daily as part of your maintenance routine.

Reducing to 3 Capsules for Maintenance

For others, after achieving the desired health benefits, it’s possible to reduce the intake back to three capsules daily. This maintenance level should be optimal to sustain your health and wellbeing while still providing the essential nutrients your body requires. Again, individual differences play a significant role, so be attentive to your body’s needs.

Freeze-Dried Beef Organ Powder: Serving Suggestions

For those who prefer the freeze-dried beef organ powder, the recommended serving is 1 1/2 teaspoons. This versatile powder can be added to various cooked meals, smoothies, yogurt, shakes, meats, or eggs, providing a convenient and tasty way to incorporate the health benefits of organ meats into your diet.

Beef organ wholefood supplements, whether in capsule or powder form, offer an excellent way to boost your nutrient intake and support your overall health. Remember that each person’s requirements are unique, and it’s important to begin with a gradual approach when incorporating supplements into your routine. From three capsules, gradually increase to six capsules to assess your body’s response, and then find your optimal maintenance level. With freeze-dried beef organ powder, you can conveniently add this nutritious supplement to a variety of dishes, allowing you to experience the benefits in a way that suits your taste and lifestyle.

We’ve provided a simple table below to help you on your supplementation journey. Let us know how you find incorporating beef organ wholefood supplements and share your experiences with others yet to join our community.

Remember that the information provided in the table is a general guideline and should be adapted based on individual health needs and goals.

Mawson and Mertz: what really happened? Another perspective

During the Australasian Antarctic Expedition of 1911–1914, Douglas Mawson and two companions, Belgrave Ninnis and Xavier Mertz, undertook an ill-fated mapping journey.

Ninnis died when he fell down a crevasse, together with the sledge carrying most of their food supplies, and later Mertz became ill and died. Only Mawson returned.

In 1969, Cleland and Southcott proposed that Mertz died of vitamin A toxicity and Mawson suffered from the effects of hypervitaminosis A because, with little food left, they were forced to eat their surviving dogs, including the liver.

This hypothesis was supported by Shearman in 1978. After re-evaluating this hypothesis, I propose that Mawson and Mertz suffered from the effects of severe food deprivation, not from hypervitaminosis A, and that Mertz died as he was unable to tolerate the change from his usual vegetarian diet to a diet of mainly dog meat.

I also suggest that Mertz’s condition was aggravated by the psychological stress of being  forced to eat the dogs he had cared for for 18 months.

Mertz leaving from the Base Camp hut via the trapdoor in the verhanda’s roof

A mapping exercise

In 1915, Mawson published an account of the 1911–1914 expedition, including the mapping  journey.3. From this we know that Mawson, Ninnis and Mertz had taken sledge dogs with them to enable rapid travel over the first part of their journey to map an area more distant than that being mapped by other members of the expedition. We also know that Mertz and Ninnis were close friends. Together they had brought the dogs by ship from England and they cared for the dogs for the 10 months the expedition party spent in the Antarctic before they set out on their fateful mapping venture.

When Ninnis fell into a crevasse to his death on 14 December, the sledge carrying most of the food supplies was lost too. Mawson and Mertz were faced  with the daunting prospect of making their way  back to Base Camp on reduced rations.

To survive, they had no option but to kill and eat the six remaining dogs.

The tragedy occurred as Mawson’s party were approaching the end of  their proposed outward journey, and the dogs were already weakened from the exertion of pulling sledges against strong winds and over very rough ground. By this time, Mawson had divided the dogs into two  teams — the strongest and fittest pulling the heavier load, which included all of the dog food and most of the human food, while the weaker dogs pulled the lighter sledge. It was the heavier sledge, with most of the food and the stronger dogs, that was lost in the crevasse.

The first of the remaining dogs died the next day. The dogs continued working until they ‘dropped’, as was their nature. They were then carried on the sledge in a comatose 

condition until shot and used for food for both man and dog. It is clear that the dogs were  already severely malnourished  — Mawson described the dog meat as “tough, stringy and without a vestige of fat”.

In his account, Mawson made it clear that all rations were shared with the utmost impartiality. It may be assumed, therefore, that Mawson and Mertz shared all rations equally until  31 December, when Mertz began to feel unwell and being vegetarian and understandably finding the dog meat difficult to stomach, requested an extra  portion of dried milk powder, while Mawson took an extra ration of dog meat in exchange. This is contrary to the suggestion by Shearman that Mertz may have found the liver less repulsive and they may have struck a ‘bargain’ on this issue.

If the food was shared equally, then in the three weeks before he died, Mertz could have eaten no more than three husky livers — about one a week or one-seventh per day. Levels of vitamin A in Antarctic husky liver vary considerably, even in healthy dogs. Although it is difficult to form an estimate of the likely vitamin A content in the livers of these emaciated dogs, it was probably low.

Vitamin A toxicosis?

In 1912, while Mawson’s expedition was in the Antarctic, the term ‘vitamins’ was first used to describe a new class of nutrients believed necessary to support life, and 1915 saw the discovery of the fat-soluble vitamin “A” in cod-liver oil and in butter. The period between the World Wars was one of great discoveries in relation to the role of vitamins and the effects of vitamin deficiencies, but it was not until after World War II that vitamin preparations became widely available, were consumed in large quantities by the general public, and attention began to focus on the possible effects of vitamin overdoses.

The symptoms of chronic hypervitaminosis A are well documented. Vitamin A, being fat soluble and stored in the body to some extent, is known to exhibit toxicity at very high doses taken over long periods of time. However, most reports have been related to the ingestion of large amounts of the vitamin in tablet form over extended periods of time — usually several years rather than weeks.

Symptoms have included coarseness and sparseness of hair of the scalp, eyebrows and other parts of the body; dryness of the skin, ulceration, and desquamation;

hepatosplenomegaly; anorexia and diarrhea; cessation of menstruation; hemorrhagic tendency; hyperostosis, bone tenderness or pain, especially of the distal extremities

(which may be accompanied by weakness); myalgia; and dizziness, blurred vision, increased intracranial pressure (causing bulging of the fontanelles in infants and severe headache in adults); and irritability and depression.

Furman described a laboratory worker who self-medicated with 1 300 000 IU of vitamin A over a 27-hour period and suffered intense headache, blurred vision, and was unable to sit or stand because of dizziness and vertigo. Desquamation followed a few days later. This is one of the few cases of acute vitamin A poisoning in which there was immediate medical evaluation. However, Furman noted that this case appeared to be one of individual hyperreactivity, as many other patients have taken far higher doses over longer periods without ill effect.

Nevertheless, similar to all accounts to date of presumed acute vitamin A toxicity, in this case there was a rapid onset and a rapid recovery.

Vilhjalmur Stefansson made it his life’s work to study the life and diet of the Eskimo. Some of his companions had experienced headache, nausea and weakness after eating bear liver, although they recovered the next day. On one occasion, Stefansson and three companions experimented by dividing up a bear liver between them. One man felt very nauseous, Stefansson suffered loss of appetite, the other two suffered no ill effects.

UND Office of University Relations

While some of the symptoms suffered by Mawson and Mertz occur in hypervitaminosis A, none were exclusively those of vitamin A toxicity. However, these symptoms may also be attributed to severe food deprivation and the effects of the cold and wet conditions which the pair were forced to endure. Mawson and Mertz had no change of clothing and wore their damp clothing for weeks on end, to say nothing of sleeping in damp sleeping bags.

Further, no mention is made by Mawson, in his meticulous account, of the symptoms which would have been expected in acute vitamin A toxicity — headache, nausea, vomiting, dizziness, weakness of the legs, excessive tiredness or hemorrhaging. If there was sufficient vitamin A present in the husky livers to cause acute toxicity, more of these acute symptoms should have been apparent. Indeed, it is difficult to comprehend how Mawson could have completed his journey enduring the unrelenting extreme physical exertion.

Vitamin A toxicosis?

Why did Mertz, and not Mawson, die? Mertz was a near vegetarian. He accepted the need to eat pemmican biscuits, made from dried, powdered beef, as part of the sledging rations, but this is a far cry from being forced to eat the flesh of his beloved dogs.

When Ninnis died, Mawson suffered the loss of a companion and a member of the party for whom he was ultimately responsible, but Mertz had lost a close friend. Indeed, he had lost seven friends, one human and six animals.

Not only did Mertz lose these friends, but the remaining dogs were dying, one by one. In addition to witnessing their suffering, he then had to assist in their final moments

and eat their flesh. Also, a sudden change of diet to one consisting mainly of meat would have added to the difficulties that he and Mawson faced. Draper has reported that a sudden change from a mixed diet to a primarily meat-based diet leads to asymptomatic ketosis and ketonuria. This being the case, the change by Mertz, not from a “mixed” diet but from a vegetarian one, to a diet based primarily on meat may have resulted in problems which have not yet been considered.

These two additional factors, the psychological stresses related to the death of a close friend and the deaths of the dogs he had cared for, as well as the need to kill and eat his remaining dogs, and the physiological stress caused by a change in diet, may have contributed to Mertz’s death.

Paradoxically, Mertz’ death probably saved Mawson’s life, as it made available a double ration of the remaining food. Although the nutritional value of the dog meat would have been low, such little as there was, may have contributed to Mawson’s survival.

Hunter-Gatherers Prized Organ Meats

Liver in particular is famous for its “anti-fatigue factor.” It’s used worldwide by athletes & everyday individuals as a natural, long-lasting energy boost.

Who wouldn’t love some extra (all-natural!) energy? Our hunter-gatherer ancestors viewed raw organ meats as their #1 prized delicacy for a reason.

Raw organ meats

In particular, Weston A. Price discovered that certain foods, such as liver, bone marrow, fish eggs, egg yolks, and tallow, were staples in our ancestors’ diets to allow for easyconception and the creation of healthy, beautiful babies.

Today, modern science tells us why. For instance, we know that healthy sperm and fertile eggs require animal-sourced vitamin A to function properly. Organic Grass fed, liver is hands down the best source.

Our approach at Grassland Nutrition 

At Grassland Nutrition we care about sourcing the highest quality liver on the market and work with OBE organic in the Australian Channel Country, where the cattle naturally grazes on over 250 native species of plants and watered by natural rainfall. 

Our Organic liver has been freeze-dried, the term desiccated is a broad term and could indicate a variety of drying methods, including heat which can destroy the nutritional content of the liver, basically leaving the desiccated liver with no national value.  

The benefit of freeze drying the liver is the flavour is milder and much more palatable and can be easily mixed into your existing foods.  One standard serving of Grassland Nutrition Liver/Kelp  taken daily is 3 grams (3.5:1 Ratio), which roughly works out to a standard serving of liver per week.

Debunking concerns over eating Beef Liver: Is It Safe?

We often hear concerns about the safety of frequently consuming beef liver. 

The liver is a vital organ in the body performing several important functions. It stores nutrients, detoxifies the blood and makes bile to aid the digestion of fat. 

This blog has been created to look more closely at these common objections in order to debunk exactly what is perceived to be a risk and your key considerations to make an informed decision for what is right for you. 

Beef liver is a renowned superfood containing around 25 essential vitamins and minerals, such as vitamin A, vitamin B12, and iron. 

Is it safe? And if so, how much is healthy? Read on…

Beef liver is ‘nature’s ready-made nutrient package’ and is also a good source of many trace minerals, such as copper and selenium. As it is also high in folic acid, it helps the body to produce and maintain new cells. This is essential for fertility, and particularly in pregnancy to support foetal development. 

A great source of essential fatty acids like Omega-3s and Omega-6s, for heart, brain and eye health. Beef liver supports cognitive development in young children and throughout the development cycle, from 6 months to adulthood.

It improves energy levels and has anti-inflammatory and antioxidant properties. With a good metabolic health approach, consuming beef liver can help to offset the biggest diseases in modern society today, such as heart disease, cancer and dementia.

Beef Liver ‘risks’

Beef liver contains high levels of Vitamin A that helps support vision, the immune and reproductive system…but Vitamin A is reported to cause adverse effects when excessive amounts are consumed as reported through Government and by standardised dieticians and nutritionists.

This deemed to be high risk Vitamin A advice is two-fold and without evidence: 

  • beef liver contains many toxins, and 
  • the dangers to be aware of given its high vitamin A content.

As we began in this blog, the liver plays a vital role in neutralising toxins, yet it does not store them. Instead the liver serves as storage for essential nutrients such as vitamins A, D, E, K, B12, folic acid, as well as minerals like copper and iron. These nutrients equip the body with the necessary tools to eliminate toxins.

Concerns about vitamin A arise from studies where doses of synthetic vitamin A were discovered to cause problems and potentially lead to birth defects. However, the natural form of vitamin A found in the liver is an essential nutrient for human health and does not cause issues unless in extremely large amounts.

Here we refer to the comprehensive The Liver Files as detailed in Weston A Price’s blog.

  • acute toxicity from vitamin A has only been induced by long-term consumption of megavitamin tablets containing 100,000 IU synthetic vitamin A per day over many months. 

The suggested toxic dose of 100,000 IU per day can be found in approximately three 100-gram servings of beef liver. 

“It is estimated that primitive diets included around 50,000 IU of vitamin A per day.”

  • With reference to pregnant women, a study found no cases of congenital malformations among 120 infants exposed to more than 50,000 IU of vitamin A daily
  • Another study examined blood levels of vitamin A in pregnant women and discovered that a dosage of 30,000 IU per day did not correlate with birth defects

In pregnancy, beef liver helps support healthy iron levels and traditional nutrition journals recommended consuming beef liver regularly. Nowadays the message has turned to that of caution and thus hesitation and even avoidance when so many benefits are to be had. 

The Natural Library of Medicine also emphasises in a paper focused on Vitamin A toxicity, published in August 2022 that:

  • “Reported incidences of vitamin A toxicity are quite rare, with fewer than 10 cases per year from 1976 to 1987.” 

Therefore it is highly unlikely to develop vitamin A toxicity from consuming liver. 

How to enjoy beef liver safely

As we have reviewed, whole food beef liver is known for its high bioavailability and nutrient content, including iron. When it comes to iron, beef liver is regarded as the best food source as it contains a type of iron called heme iron, which is more easily absorbed and utilised by the body, compared to non-heme iron found in plant-based sources. Heme iron has a higher bioavailability, meaning a greater percentage of the iron can be absorbed by the body.

Mercola recently published a paper on the possible effects of too much iron in the brain stating: 

“Most people are deficient in copper and actually need more copper in order for their iron metabolism to function properly.

Depending on your copper levels, you may need to eat copper-rich foods, such as grass fed

beef liver.”

“Retinol, which makes copper bioavailable, is also important. It’s found in beef liver and

beef organs, so if you eat that, you may not need any kind of supplement.”

Freeze-dried beef liver is highly concentrated, three times as nutrient dense as its raw equivalent. The freeze-drying process helps preserve the nutritional content of beef liver, even after the water content is removed.

Freeze-dried beef liver is lightweight and convenient to store, with a long shelf life (Grassland Nutrition’s products can be stored for three years). Freeze-dried beef liver doesn’t need to be refrigerated and can be carried when on the move or added to meals for a boost. This is a practical option for those with busy lifestyles, or that have limited regular access to fresh liver.

Convenience and peace of mind with wholefood supplements 

Overall, freeze-dried beef liver is a convenient and beneficial option for individuals seeking to increase their overall health, build strength, optimise energy levels  and thrive. In practical terms it has been known to aid sleep, digestion, build strength, support and maintain energy, improve the condition of skin, hair and nails as well as alleviate headaches. 

By choosing whole food products you can enjoy a plethora of nutrients and live life to the full, naturally without fear of overdoing it. 

By reading trusted sources and understanding what your individual body needs, you can safely enjoy beef liver and get all its amazing health benefits.

Consider beef liver supplements; taking a natural whole food supplement with no fillers or flow agents will help you maintain a healthy balance. Always source organic or grass-fed beef liver from trusted suppliers. This will ensure that the liver comes from grass-fed and nurtured animals that haven’t been exposed to antibiotics or other toxins. Here at Grassland Nutrition, it is essential we know the animal has lived a full life and has been free to roam natural pastures where no pesticides have been present and fed on a diet of grass all its life.

Grassland Nutrition’s organic sourced Australian grass-fed freeze-dried beef liver is available in capsules and powder and whole food chunks

4 Benefits of Beef Liver for Your Child’s Health

We’ve compiled 4 great reasons to begin incorporating beef liver to your child’s diet and easy ways for you to add beef liver in your daily family food preparation.

Nutrient-Dense: Beef liver is a nutrient-dense food, meaning it is packed with vitamins and minerals that are essential for the body’s growth and development. It is a rich source of vitamin A, iron, zinc, and vitamin B12, all of which are crucial for maintaining good health.

Supports Brain Development: The high levels of iron and vitamin B12 found in beef liver are important for brain development and function. These nutrients are essential for the production of myelin, a fatty substance that surrounds nerve fibers and helps to transmit signals between brain cells.

Boosts Immune System: The high levels of vitamin A and zinc in beef liver also play a crucial role in supporting the immune system. Vitamin A is important for maintaining healthy skin and mucous membranes, while zinc is involved in many aspects of immune function, including the production of white blood cells.

Helps with Anemia: Beef liver is a great source of iron, which is important for the production of hemoglobin, a protein in red blood cells that carries oxygen throughout the body. Iron deficiency anemia is a common problem in children, and including beef liver in their diet can help prevent or treat this condition.

Follow the daily recommended guidelines and ensure that the beef liver you purchase is from a reputable source to avoid potential contamination with harmful substances.
