Discover Why Liver is King of the Organ Meats

internal organs cow

Organ meats are becoming increasingly popular in the health and supplement space with requests for obscure organs hitting our inbox each day. Thymus, spleen, brain, tongue and ovaries (yes really) are commonly sought-after products as the marketers claim wildly creative benefits.

As a organ supplement company ourselves we look at every new request by asking the following questions;

  1. What are the nutritional benefits from organ X
  2. Can organ X be reliably/regularly sourced at a high quality
  3. Will organ X be cost effective for the consumer 
  4. How does it stack up against the big 3 (liver, heart & kidney)

More often than not our investigations into nutritional information, supply chain, consumer benefits and pricing lead us to the same conclusion ... 

Beef liver is One of the Most Nutritionally Dense Organs on the Planet.

In the table below we explore the most common nutrients across 100g of 7 popular organs outlining the percentage of recommended daily intake. The green coloured cells denote the highest values.

As you can see from the data if your goal is to obtain the best nutritional punch for your dollar, beef liver takes centre stage. This is the core reason that we offer it as a standalone product in our Primal Energy and why it's a foundational organ in our Primal Multi blend. Yes we could source other organs, put them in a bottle with a fancy label but the data doesn't lie and the benefits are simply outweighed by the mighty liver king and its two close relatives the heart and kidney - which contain selenium, CoQ10, collagen and elastin.

Note - We do plan on expanding our range but our team have clear goals to research complementary products that truly add value in light of the information above.

Why Size Matters

It's also important to note that beef liver is a large organ in comparison to the brain, spleen and thymus etc. Smaller organs offer less product making them more difficult to obtain in volume which ultimately have to be offered at a premium price... all while delivering less nutrients than beef liver!

The Big Benefits of Beef Liver 

As you've probably gathered beef liver is THE most concentrated source of just about every nutrient, including vitamins, minerals, healthy fats and essential amino acids. You can learn more about the specific nutrients in liver here. While less common organs may offer varying nutritional profiles, liver deserves the crown and is truly king of the organ supplements.

Beef Liver Capsules

Our beef liver and beef organ supplements are contained in easy-to-take flavourless capsules. They are non-defatted to preserve the fat-soluble nutrient content (including vitamin A) and are freeze-dried, which also helps preserve the full range of nutrients. They are 100% hormone, antibiotic and GMO-free and are 100% grass-fed and organic from the pristine Tasmanian pastures.
