Know you need iron but hate how the generic stuff makes you feel?

The stomach issues, constipation and bloating that come with synthetic iron don't have to be part of it.

This is beef spleen, one of the richest natural sources of iron there is, because its literal job in the animal is storing and recycling red blood cells. Rapid Beef Spleen delivers 15mg of natural heme iron per serve, independently verified by BVAQ Laboratories. Easily absorbed, gentle on your gut, and sourced from 100% grass-fed New Zealand cattle.

Made & Manufactured in Australia
Restores Energy & Beats Fatigue, Naturally
Gentle on the Stomach. No Nausea, No Constipation
Supports Immunity, Recovery & Everyday Vitality

To get the heme iron in a daily serving of capsules from food alone, you'd need to eat around 750g of premium steak, impossible right?!

Natural Heme Iron One Ingredient Only Easily Absorbed Gentle On Digestion Grass-Fed BVAQ Lab Tested

✔️Increases Energy & Reduces Fatigue

Beef spleen is one of the richest natural sources of heme iron, the form your body absorbs most easily. It supports red blood cell production and oxygen delivery, helping you feel more energised, alert, and less fatigued.

✔️Supports Strong Immunity

Naturally high in zinc, copper, and peptides, beef spleen helps strengthen immune defences and promote a balanced immune response. Supporting your body’s natural resilience against stress and illness.

✔️Promotes Healthy Blood & Oxygen Flow

The spleen plays a key role in recycling red blood cells and maintaining healthy circulation. Supplementing with spleen provides the same essential nutrients your body uses to build and maintain healthy blood.

✔️Aids Recovery & Performance

The combination of iron, B12, and amino acids supports muscle recovery, endurance, and stamina making beef spleen ideal for athletes or anyone feeling run-down.

✔️Gentle on Digestion

Unlike synthetic iron supplements, which can cause nausea or constipation, beef spleen provides iron in its natural, food-based form, making it easier on the gut and more efficient to absorb.

6. Supports Healthy Skin & Cellular Function

The trace minerals and bioavailable nutrients in spleen particularly copper and zinc, contribute to collagen formation, skin integrity, and overall cellular health.

100% Pure Grass-Fed Beef Spleen... Nothing Else

We believe the best supplements don’t need to be complicated. That’s why our Beef Spleen Capsules contain just one ingredient, pure, freeze-dried grass-fed Australian beef spleen.

No fillers. No flow agents. No additives. Just the real, nutrient-dense organ in its natural form, carefully preserved to maintain its rich content of iron, B12, zinc, and copper exactly as nature intended.

Every batch is independently tested by BVAQ Laboratories to confirm purity and potency, including the highest verified iron level of 10,000 mg/kg.

Pure, powerful, and proven, it’s nature’s most effective form of iron, with nothing to hide.

When it comes to organ supplements, not all organs serve the same purpose. Beef liver and beef spleen both offer benefits...but they shine in very different ways.

🩸 Iron Content: This Is Where Beef Spleen Excels

Beef spleen is one of the richest natural sources of heme iron available.

  • Beef spleen contains up to 5–7× more iron than beef liver (per 100g)

    Iron in spleen is heme iron, the most bioavailable form, meaning your body absorbs and uses it more efficiently

    Spleen is naturally involved in red blood cell storage and recycling, which is why its iron concentration is so high
  • If iron support is your goal, beef spleen is the clear winner.

🧠 Beef Liver: Broad Nutrition, Lower Iron

Beef liver is often called “nature’s multivitamin” — and for good reason. It’s rich in:

  • Vitamin A
  • B vitamins (especially B12)
  • Copper and choline

However, its iron content is significantly lower than spleen, making it better suited for general nutrient support rather than targeted iron replenishment.

Frequently Asked Questions

  • Many people notice improvements in energy, focus, or vitality within a few weeks. However, individual results vary depending on your current iron & B12 levels, diet, and lifestyle. Consistent daily use is more important than the exact timing.

  • Our formula contains just one ingredient — pure grass-fed Australian beef spleen — with no fillers or additions. It has the highest verified iron content of any tested beef spleen supplement (10,000 mg/kg), and uses natural, highly bioavailable heme iron for better absorption and gentler digestion.

  • If you’re using other iron or nutrient supplements, it’s wise to check your total daily intake and consult your healthcare professional. Because our product supports iron and other nutrients naturally, you may or may not need additional ironsupplementation depending on your status.

  • Our beef spleen capsules are generally well tolerated. Because they contain high-potency iron and nutrient cofactors, people with iron overload conditions (e.g., hemochromatosis), certain blood disorders, or those pregnant/breastfeeding should get medical advice before use. Some users find taking with food helps reduce any mild digestive sensitivity.

  • Beef spleen naturally provides iron, vitamin B12, and trace minerals that can support healthy energy and nutrient levels during pregnancy. However, because every pregnancy and nutritional need is unique, it’s important to speak with your healthcare provider before introducing any new supplement while pregnant or breastfeeding.

  • The capsules have no taste or smell.

  • Take your beef spleen capsules once daily with a meal, breakfast or lunch is ideal. Taking it with food helps your body absorb the iron and other nutrients more efficiently and makes it gentler on the stomach. For consistent results, take it at the same time each day.
