  • Traditional cultures and early ancestral healers believed that eating the organs from a healthy animal would strengthen and support the health of the corresponding organ of the individual. The immune-boosting effects of beef spleen may be partly attributable to this principle called ‘like-supports-like’. In other words, many of beef spleen's potential health benefits may stem from its ability to nourish the spleen of the person or animal consuming it. 

  • Spleen tissue extracts may be of benefit in enhancing general immune function because of the many potent immune system-enhancing compounds secreted by the spleen, such as the peptides tuftsin and splenopentin.(1) 

  • Tuftsin stimulates macrophages that have taken up residence in specific tissues like the liver, spleen and lymph nodes. Tuftsin also helps mobilise other white blood cells to fight against infection and cancer. A deficiency of tuftsin has been associated with signs and symptoms of frequent infections.(1) 

  • Splenopentin, like tuftsin, has also demonstrated significant immune-enhancing effects. Its effects are primarily directed toward enhancing the immune system’s response to regulating compounds that stimulate the production of white blood cells.(1)  

  • Splenopentin has also been shown to enhance the activity of natural killer cells. Natural killer cells destroy cells that have become cancerous or infected with viruses and are the body’s first line of defence against cancer.(1)

  • Beef spleen is an exceptionally rich source of highly bioavailable iron, containing five times as much total iron and nearly 30 times as much heme iron, as compared to beef liver.(2)  Iron is vital for a number of key bodily functions, such as helping to provide oxygen to organs and muscles, and for certain enzymes in the body to function normally. When a dog is deficient in iron it can lead to anemia. Dogs can become lethargic, weak, and more prone to disease and illnesses.

  • Beef spleen is a rich source of selenium. Selenium is a potent antioxidant which is essential for the correct function of metabolism. In a dog’s body, it is important for its role in thyroid metabolism, synthesis of DNA and reproduction.(3) Its antioxidant properties can help to prevent oxidative damage that can cause premature aging, cancer and inflammatory diseases.

  • According to Traditional Chinese Medicine theory, the Spleen plays an important role in various physiological functions, including digestion and absorption of nutrients, regulation of water retention and excretion, facilitation of blood perfusion to skeletal muscle and on the optimal functioning of the immune system.(4)

Top quality & easy to use

Sheba & Takoda are my young and fit herding mix dogs. They’re mostly raw fed. I use Narelle’s beef spleen and pancreas to add healthy variety to their meals. These two ingredients aren’t so easy to come by fresh from our local butcher. These products are also soo easy to use when we’re travelling so I don’t have to handle fresh offal.
My dogs will certainly get to enjoy more of Narelle’s creations over time. Very much appreciate her learned nutritional advice.
Thank you for your all round excellent service!

Great product

My dogs love the essential organs but especially the organic beef spleen. It’s also great to be able to add organs to their diet that, as a diy raw feeder, I find hard to access. Shipping is always prompt and products always look ver high quality.

Organic Beef Spleen powder

My 8 yo Danny has recently had bad blood results & 1 1/2 years ago had his cancerous spleen removed.
He likes the product & I am hoping it will help, 1/2 way through the 1st container. Have just ordered another. 🤞


Hi Narelle,

My long coat GSD is the fussiest dog and will NOT eat anything that isn’t chicken…
As I’ve been worried about him not having all the core nutrients he needs to to grow healthily and have tried everything from Prime rolls, to Lyka, to raw in which he would not eat, not to mention all the money that has been spent. I am writing to tell you that you are a genius! I purchased the beef liver and spleen as recommended by you and we have success! My boy eats everything!
Thank you so much on creating such a wonderful product.
This is a first, we will continue to use your products in his food.

Thank you again!
Jess Leaf & Kingston 🐶
