The Iron Mistake You Might Be Making (and How to Fix It)

Chances are… you’ve done everything right.

✓ A visit to your GP

✓ Lab results showing low iron

✓ Picking up the prescription or supplement

...but weeks later, you’re still fatigued and foggy, maybe even accepting this as your “normal.” Now constipation, nausea, and a funny tummy are in the mix. 

Why am I still feeling like this?

Well, let's take a pause for a moment. We need to consider how the body absorbs, regulates, and uses iron.

When it comes to iron, more is not always better — especially when it comes to supplementation. We have to look beyond the numbers and consider how the body actually absorbs, regulates, and uses iron.

So, are you ready to find out what's actually in that 7.21mg of iron in Beef Liver & Spleen Capsules?

Let's dive in.

SYNERGY – Cofactors

In nature, nothing exists in isolation. Our bodies work best with foods that are as close to their natural form as possible. Every vitamin, mineral, and enzyme interacts in a finely tuned system that your body instinctively knows how to use.

When we isolate one nutrient and take it in high doses, we lose the natural cofactors that help it do its job, and that’s where problems start. With iron supplements, the most common issue is constipation.

It sounds counterintuitive, doesn’t it? You’d think more of a “good thing” would help, but nutrients don’t work alone.

Take Vitamin A, for example. Research shows that correcting a Vitamin A deficiency can actually resolve iron deficiency — even without adding more iron. That’s because Vitamin A helps mobilise stored iron and supports red blood cell production.

In other words, the key isn’t just more iron — it’s the right balance of nutrients that help iron function properly.

This is the principle behind Beef Liver & Spleen. It’s not just another iron supplement — it’s a whole-food source designed by nature for synergy. Spleen provides one of the richest sources of bioavailable heme iron, while liver contributes Vitamin A, copper, and B vitamins — all crucial cofactors for iron absorption, transport, and utilisation.

DOSE – Regulation

Iron is one nutrient where more is not always better. Our clever bodies have systems to regulate iron levels and protect against overload. Too little leads to fatigue and brain fog; too much becomes toxic, damaging tissues, driving oxidative stress, and disrupting gut health.

One mechanism is known as the Mucosal Block Theory — a safety system that limits how much iron the intestines absorb. When your stores are full, your gut absorbs less. When they’re low, absorption increases.

Another is Hepcidin — a hormone made by the liver that acts like a gatekeeper. When iron levels or inflammation are high, hepcidin rises, blocking iron absorption from the gut. When iron is low, hepcidin drops, allowing more in. It’s a fine-tuned system that keeps iron tightly controlled.

Here’s the catch: traditional iron supplements often overwhelm these natural controls. The body can only absorb a small portion of the dose — the rest lingers in the gut, where it can generate free radicals, irritate the intestinal lining, and disrupt gut bacteria. The result? Nausea, constipation, bloating, and inflammation.

So, is 7.21mg of iron in Beef Liver & Spleen enough?

Surprisingly, yes — when it’s in the right form. Clinical research has shown that just 10 mg of ferritin-bound iron per day significantly improved iron status in women with iron deficiency anaemia within 9 weeks (1). Because this form mirrors iron in nature — bound to proteins and delivered with its cofactors — it’s absorbed efficiently and used effectively, without triggering those regulatory blocks or gut side effects.

That’s exactly how Beef Liver & Spleen works: a modest yet highly bioavailable dose of heme iron, naturally packaged with the nutrients your body recognises and knows how to use.

Less is more.

INHIBITION – Competition

Certain foods and nutrients can block or reduce iron absorption. For example:

• Coffee and tea contain polyphenols and tannins that bind to iron in the gut.
• Calcium (from dairy or supplements) competes for the same transport pathways, crowding iron out.
• Zinc and other minerals share similar absorption sites, so high doses of one can reduce the uptake of another.

This is why timing matters: spacing your iron-rich foods or supplements away from coffee, dairy, or zinc can make a meaningful difference in how much iron your body actually gets — and keeps.

In summary

Nature Knows Best

Your body is incredibly intelligent. It knows how to absorb, regulate, and use nutrients when they come in the right form, balance, and dose. Isolated, high-dose supplements may seem like a quick fix — but they often work against your body’s natural systems, causing side effects and poor absorption.

Beef Liver & Spleen works differently. It delivers a modest, functional dose of heme iron (7.21mg), paired with nature’s own cofactors — Vitamin A, copper, and B vitamins — that help your body use iron effectively. It supports gut health and works with your body’s natural regulation, not against it.
