• Beef Liver boasts elevated energy and stamina levels: Its ample supply of vitamin B12 serves a pivotal function in generating red blood cells and transporting oxygen throughout the body. Recent research published in the 2017 edition of the Journal of the International Society of Sports Nutrition discovered that taking vitamin B12 supplements can enhance athletes' endurance and aerobic capabilities.
  

  In order to maintain proper brain function and the synthesis of neurotransmitters, it is essential to have adequate levels of choline in our bodies. Beef liver is a rich source of this nutrient. A study that was published in the American Journal of Clinical Nutrition revealed that individuals who consumed higher amounts of choline exhibited enhanced cognitive performance.
  

  Beef liver is a significant contributor to liver health and detoxification due to its richness in cytochrome P450 enzymes. These enzymes play a critical role in eliminating harmful toxins from the body. According to a 2018 research paper published in the Journal of Nutritional Biochemistry, these enzymes are essential in safeguarding the liver from damage while enhancing healthy liver function.
  

  Enhances Skin, Hair, and Nails: Beef Liver boasts a high concentration of vital nutrients such as collagen and biotin that promote optimal health for skin, hair, and nails. According to a 2019 evaluation published in the Journal of Cosmetic Dermatology, collagen intake can enhance skin elasticity and moisturization, thereby providing a more rejuvenated and youthful appearance.
  

  Beef liver is a great source of heme iron, which is readily absorbed by the body and more effective than non-heme iron from plant sources. Sufficient iron consumption is crucial for generating hemoglobin, a protein that carries oxygen throughout the body. A Nutrients journal study conducted in 2014 concluded that heme iron plays a crucial role in preventing anemia and supporting overall health.
  

  Beef liver has abundant trace minerals like zinc and selenium that are vital for promoting a robust immune system. According to an article in the journal Nutrients of 2018, zinc is an essential mineral that regulates the immune response, while a Journal of Nutrition study conducted in 2015 underscored the role played by selenium in maintaining optimal immune function.
  

  Beef liver contains a high concentration of vitamin B12 that is crucial for DNA synthesis and restoration. According to a 2012 research study released in the International Journal of Molecular Sciences, vitamin B12 helps maintain genome stability and prevents DNA damage.
  

  Beef liver is a beneficial food that encourages healthy bone development. This is due to the high levels of vitamin K2 it contains, which is vital for maintaining calcium metabolism and bone structure. A recent scientific study published in the journal Nutrients in 2017 stated that vitamin K2 is crucial for preventing bone degradation, enhancing bone density, and minimizing the likelihood of fractures and osteoporosis.

  The truth about the meaning of Grass-Fed:

  Even though cattle are free roaming on a pasture (grass) based farming system, it should be noted that pasture growth is seasonal, therefore supplementary feeds may be used in times of feed shortages during winter or dry summers. If supplements are used then converted pasture feeds (such as hay and silage) or winter crops (such as fodder beet) are most commonly used.

  
  

• You might be surprised to learn that in some traditional cultures, only the organ meats were consumed. The lean muscle meats, which are what we mostly eat in Australia today, were discarded or perhaps given to the dogs - Chris Kresser

  
  

  Aside from the macronutrients, beef liver is an ancestrally revered food because it is a nutrient-dense source of vitamins and minerals: - Mark Sisson

  
  

  I had a friend who was deficient in all sorts of things. I gave him a bottle of desiccated grass fed beef liver those and he took them and he was like, I feel like I’m on crack. Like, I have so much energy that I cannot even begin to understand how tired I was for so long. So yes, the desiccated beef liver. - Tim Ferris

Additional notes:

• Un-defatted beef liver includes fat-soluble vitamins, like vitamin A.
• If a beef liver supplement claims to contain 0% fat and vitamin A, it may be questionable, as vitamin A is a fat-soluble vitamin.
• 3g of desiccated (dried) beef liver equals 28g of fresh liver.
