Beef Spleen: Nutrition, Benefits, and Supplements
Table of Contents
In animals, the spleen promotes a healthy immune system. And when eaten as food, it offers many health-promoting benefits. Many cultural groups have used beef spleen to successfully strengthen their own immune systems.
Let’s explore the benefits of beef spleen, while taking a closer look at its specific bounty of nutrients.
What is Beef Spleen?
Beef spleen is simply the spleen of a cow. In this context, we’re obviously talking about using spleen as food.
- Breaks down old or damaged RBC’s (red blood cells)
- Produces white blood cells to fight infections
- Stores blood in case of sudden demand
Historically speaking, humans have either eaten spleen or processed it into spleen extract, which contains most of the organ’s active ingredients.
But are these uses legitimate? Let’s look at beef spleen’s nutrition values to find out.
Beef Spleen Nutrition
Like nearly every organ meat (besides polar bear liver which has enough vitamin A to kill 52 adults!), beef spleen is incredibly nutritious. It’s rich in protein, cholesterol, heme iron, and more. Here are the full nutritious facts:
Beef spleen nutrition: 100 grams
|Total fat||3 grams||5%|
|Saturated fat||1 gram||5%|
|Vitamin E||0 mg||0%|
|Vitamin K||0 mcg||0%|
|Vitamin B6||0.1 mg||4%|
|Vitamin B12||6 mg||95%|
|Vitamin C||38 mg||76%|
Beef spleen is a good source of dietary cholesterol. Actually, a great source when considering that it is lean and low in calories. Just 100 grams of spleen contains 88% of your recommended daily value.
And no, cholesterol isn’t unhealthy — contrary to conventional opinion. The human body uses both endogenous and exogenous cholesterol to produce important steroid hormones like progesterone, pregnenolone, and DHEA. These “youth-associated” hormones oversee processes as fundamental as cellular regeneration.
The importance of cholesterol is highlighted when you look at what happens when you don’t get enough of it. Low cholesterol levels are correlated with depression, brain fog, and other mental health problems.
Despite the vilification of cholesterol, we’ve known of it importance since at least 1948. Back then the famous Framingham heart study found that people with supposedly optimal cholesterol levels had lower “verbal fluency, attention/concentration, abstract reasoning, and a composite score measuring multiple cognitive domains” than those with ‘high’ cholesterol did.

Beef spleen is also rich in niacin AKA vitamin B3. A 100-gram serving contains nearly half your RDV. Niacin plays an important role in cognitive function and also helps your body utilize carbohydrates for fuel (this is important, even on a low-carb keto and carnivore diet.
Just 100 grams of beef spleen contains 250% your iron RDV. Iron helps your body produce healthy, fully oxygenated blood.
The quality of your dietary iron intake is important, too. Spleen contains highly bioavailable heme iron. Up to 35% of the heme iron you ingest is utilized by your body — many times more than the iron provided by plant-based products.
3 ounces of beef spleen contains nearly all the vitamin B12 you’ll need for the day. If you complement this small portion of spleen with some muscle meat, eggs, and dairy, you’ll meet the full RDV with ease.
Other Nutrients Unique to Spleen
Beef spleen contains certain small proteins, called peptides.
Finally, beef spleen’s peptides and other proteins may enhance the activity of your body’s “natural killer” (NK) cells. NK cells secrete chemicals that turn on the immunological functions of other cells, making them critical to the initial immune response.
The peptides in spleen are so potent that they can be formulated into an extract called splenin. This extract is used to directly support immune health.
Beef Spleen Health Benefits
The immune-boosting effects of beef spleen can be explained by an organ meat principle called like-supports-like.
As naturopathic doctor Ron Schmid explains, “radioisotope labeling studies in animals have shown conclusively that, when eaten, organs and glands selectively travel to the corresponding organs and glands in high concentrations. This research […] lends credence to the ancient practice of eating animal organs to help ensure health in one’s corresponding organs…”
- Boosting the immune system
- Alleviating autoimmune diseases
- Ulcerative colitis
- Rheumatoid arthritis
- Reducing inflammation
- Improving blood health
- Improving digestion
Sourcing Quality Beef Spleen
Quality is everything when it comes to organ meats. And beef spleen is no exception. Animals who live overly stressful lives may have less nutritious organ meats.
More research is needed in this area, but several fascinating studies on worms give us some hints about the potential quality difference. These studies found that the information present in a worm’s polyamine proteins can be transferred from one creature to the next upon ingestion.
For these reasons, we’d encourage you to source your beef spleen and other organ meats from a trusted local source. Or from certified grass-fed and finished cows.
If you live in an area with a local farmer’s market or butcher shop, these are usually the best places to check.
For those of us who lack access or seek greater convenience, online meat subscriptions like butcher box also offer organ meats and may carry spleen.
Beef Spleen Supplements
If you’re unsure of your ability to source high-quality beef spleen, then it may be time to consider a different solution: cow spleen specific, or full-spectrum organ meat supplements.
But not all spleen and organ supplements are created equal. When deciding on a supplement, consider the source! Also consider the following markers. Does it…
- Come from pastured cows?
- Come from grass-fed cows?
- Come from an area known for its cattle?
- Have its fat content intact (i.e, be non-defatted)?
- Contain no fillers, flow agents, or other additives?
- Come from cows that are hormone and GMO-free?
- Have its biological activity intact (ie, be freeze-dried)?
How to Cook Beef Spleen
Spleen may be an unusual food for most Americans, but there’s no reason it should stay that way. The following recipe turns beef spleen into an approachable, enjoyable meal for the whole family.

Beef Spleen: The Takeaway
Nose-to-tail eating is part of our evolutionary dietary heritage. For nearly 2 million years humans ate mostly meat. And by meat, we mean the whole animal, especially nutrient-dense organs like spleen.
It’s no coincidence that when you eat even a small portion of organ meats like spleen, liver, sweetbreads, heart, and brain along with the muscle meats that are popular today, you get a near perfect intake of protein, fat, vitamins, and minerals.
Eating organ meats like beef spleen might seem unusual, but it actually played a significant role in helping us become the super-intelligent animals we are today.
Beef spleen is rich in vitamins, minerals, and rare peptides that are produced exclusively in its tissue.
As far as beef spleens effects go, like-supports-like: spleen and its active ingredients may enhance your own immune health in a way that other foods fall short. If you haven’t already, consider adding spleen or spleen supplements to your keto or carnivore diet.
