Primal Iron - Grass Fed Beef Spleen

Nutritionally speaking, dried and fresh beef spleen are virtually identical. The main difference is that freeze-drying removes water, concentrating the naturally occurring nutrients into a smaller volume.

Beef spleen is a traditional wholefood valued for its unique nutrient profile, particularly its naturally occurring heme iron and vitamin B12. When dried, it retains its nutrients in a form the body can readily absorb.

Key Nutrients Naturally Found in Beef Spleen:

• Heme Iron 
• Vitamin B12 

Our beef spleen comes from 100% grass-fed, grass-finished Tasmanian cattle and is freeze-dried in small batches for maximum purity.

Freeze dried beef spleen is available in both capsule and powder form, and the taste experience can vary depending on which you choose.

• Capsules: Most people find beef spleen capsules virtually tasteless. They’re an easy and convenient way to get the benefits of organ meats without the flavour.
• Powder: Freeze-dried beef spleen powder has a rich, earthy flavour that’s true to its natural source. While some people enjoy the taste in savoury blends, others prefer to mix it into smoothies, broths, or sauces to mask the flavour.

Whether you choose capsules or powder, beef spleen is valued more for its nutrient density than its taste. Tip: If you're sensitive to taste or short on time, capsules are the most neutral option.

As a food, beef spleen can be consumed at any time of day, but many people prefer to consume in the morning as part of their daily routine.

Yes — our beef liver products are sourced from 100% grass-fed and grass-finished, pasture-raised Tasmanian cattle that are not supplemented with Bovaer® or other synthetic feed additives.

We work closely with local farms that focus on natural, traditional grazing practices. This ensures the purity of our products while maintaining full transparency across the supply chain, from paddock to capsule.

No hormones, no antibiotics, no synthetic feed additives, just real food the way nature intended.

While we source our organs exclusively from pristine, pasture-raised cattle in Tasmania, we do not rely on "certified organic" labels. Here is why:

Organic certification is a promise about how the farm is managed, but it does not guarantee that the final capsule is actually free from environmental contaminants. We prefer proof over promises.

Instead of paying for an organic logo, we invest in rigorous, independent lab testing. We screen our finished products using state-of-the-art ICP-MS technology to test for 32 heavy metals (like Lead and Mercury) and agricultural chemicals (like Glyphosate) to guarantee absolute purity.

You never have to take our word for it, you can view our unedited, zero-glyphosate lab results right here.

Yes, freeze dried beef spleen is a good natural source of heme iron. A 2 g serve of powder provides 15.3 mg iron (128% RDI) to support your dietary intake through real, nutrient-dense food.

Our beef spleen sproducts are made using a careful, low-temperature drying process that preserves the natural integrity of the nutrients without the use of heat, additives, or synthetic preservatives.

Here’s how we do it:

Step-by-Step Production Process:

• 1. Sourced Locally: We use 100% grass-fed & grass-finished, pasture-raised beef spleen from Tasmanian farms that meet strict animal welfare and food safety standards.
• 2. Fresh Processing: The spleen is trimmed, gently cleaned, and frozen shortly after harvest to maintain freshness and nutrient quality.
• 3. Freeze-Dried for Potency: Through sublimation, moisture is removed at low temperatures to preserve heat-sensitive vitamins like B12 and folate.
• 4. Milled and Encapsulated (or Powdered): The dried spleen is finely ground and packed into capsules or jars — with no binders, fillers, or flow agents.
• 5. Packed in Our Byron Bay Facility: We manufacture in-house to maintain full control over quality and consistency, from raw ingredient to finished product.

Every batch is third-party tested for safety and packaged in our purpose-built Byron Bay facility ensuring transparency, traceability, and trust.

Both capsules and powder contain the same wholefood beef spleen but differ in format, convenience, and flexibility, depending on your lifestyle and preferences.

Beef Spleen Capsules:

• Pre-measured and easy to take
• No taste or smell, ideal if you’re sensitive to flavour
• Great for travel or daily routines
• 1.5 g beef spleen per serving suggestion (3 capsules)

Beef Spleen Powder:

• Versatile for adding to food (e.g. smoothies, bone broth, patties)
• Slightly more economical per gram
• Mild organ flavour — best for those who are comfortable with natural tastes
• 2 g beef spleen per serving suggestion

Whether you prefer convenience or culinary creativity, both formats provide the same freezedried, nutrient-dense spleen, sourced from grass-fed & grass-finished Australian cattle. The beef spleen does not contain additives or fillers.
