Iron (as Ferrous Fumarate)

Iron is an essential trace mineral found in red meat, legumes, and dark leafy greens that transports oxygen throughout the body via haemoglobin — making it one of the most critical nutrients for sustained energy in women over 35. In element3 Rise (AM Formula), iron is dosed at 9mg as microencapsulated ferrous fumarate to support daily energy production, mental clarity, and immune resilience without the gastrointestinal discomfort common to conventional iron supplements.

[ 02 ] Rationale

Why this ingredient is in element3

Iron's primary role in the body is straightforward but non-negotiable: it forms the core of haemoglobin, the protein in red blood cells that carries oxygen from your lungs to every tissue and organ. Without adequate iron, your cells are effectively starved of oxygen — and the downstream effects show up as fatigue, reduced concentration, and a weakened immune response.

The 9mg dose in element3 Rise was chosen deliberately. It provides 50% of the recommended dietary intake for women, designed to complement dietary iron rather than replace it. This approach avoids the nausea and constipation that commonly accompany high-dose iron supplements, while still providing meaningful support for women whose intake may fall short through diet alone.

The form matters as much as the dose. element3 Rise uses microencapsulated ferrous fumarate, a highly bioavailable iron salt protected by a lipid coating that acts as a protective shell around each iron particle. This coating is the key engineering choice. Standard ferrous fumarate is well absorbed, but unencapsulated, it can react with the gut lining and trigger the nausea, constipation, and metallic aftertaste that lead many women to abandon iron supplementation. Microencapsulation delays release until the iron reaches the small intestine — the site of optimal absorption — and shields it from interacting with other nutrients during transit. The result is an iron form that delivers the elemental iron content of ferrous fumarate (which is one of the highest of any iron salt at roughly 33%) with markedly improved gastrointestinal tolerability and reduced taste impact.

Within the element3 Rise formula, iron works synergistically with Vitamin C, which enhances non-haem iron absorption by converting ferric iron to the more bioavailable ferrous form. Vitamin B12 and Folate (B9) further support iron's role by contributing to healthy red blood cell formation. Together, these nutrients form a complete oxygen-transport and energy-production chain.

For women experiencing persistent low energy, brain fog, or the kind of fatigue that sleep doesn't resolve, iron is foundational.

[ 03 ] Formulator's Notes

From the formulator

Iron is dosed to the RDI for women over 50. Once periods stop, your iron needs drop, so we've matched the level to this stage of life rather than overloading it.

[ 04 ] At 35+

Relevant at 35+

Iron requirements remain high for women throughout their reproductive years, but the landscape shifts meaningfully after 35. Menstrual blood loss continues to deplete iron stores, while the metabolic demands of perimenopause — including the hormonal shifts that can affect how energy feels day to day — increase the body’s baseline need for oxygen-efficient energy production.

Many women in their late 30s and 40s find their energy isn’t what it was. Iron intake is one of the everyday foundations worth keeping an eye on through this stage.

This is why iron sits in element3 Rise. At 9mg, half the recommended daily intake, it’s designed to complement dietary iron rather than replace it, delivered in a form built for absorption.

[ 05 ] Your Questions

Your Questions

What is iron?
Iron is an essential trace mineral that your body cannot produce on its own and must obtain through diet or supplementation. Its primary role is forming haemoglobin, the protein in red blood cells that carries oxygen from your lungs to every cell in your body. Iron is also required for myoglobin (oxygen storage in muscle tissue), ATP energy production, and the synthesis of several neurotransmitters including dopamine and serotonin.

What are the benefits of taking iron?
Iron supplementation supports sustained energy production, mental clarity, and immune function in women whose dietary intake falls short of requirements. Research indicates iron supports normal energy levels and concentration. For women of reproductive age, consistent iron supplementation also helps offset losses from menstruation.

What are the benefits of iron in the element³ protocol?
In element3 Rise, iron at 9mg as microencapsulated ferrous fumarate supports the oxygen transport and energy production that underpin the rest of the formula. It's paired with Vitamin C, which supports iron absorption, and works alongside Vitamin B12 and Folate in supporting normal red blood cell formation. The zinc in element3 Rest is kept separate from the iron here to avoid absorption competition.

What is the recommended daily intake of iron?
The recommended dietary intake for adult women aged 19–50 is 18mg per day, reflecting the additional requirements of menstruation. This drops to 8mg per day post-menopause. element3 Rise provides 9mg per serve — 50% of the adult female RDI — designed to complement dietary iron intake rather than replace it. The upper safe intake level is 45mg per day; amounts above this are associated with gastrointestinal distress and should only be taken under medical supervision.

What food provides iron?
Iron is found in two forms in food: haem iron (from animal sources, more bioavailable) and non-haem iron (from plant sources, absorption enhanced by Vitamin C). Rich haem iron sources include red meat, liver, and shellfish. Non-haem sources include lentils, chickpeas, tofu, spinach, pumpkin seeds, and fortified cereals. Women eating a predominantly plant-based diet often find it challenging to meet the 18mg RDI through food alone, which is where targeted supplementation like element3 Rise supports the gap.

Are there any iron side effects?
Iron supplements can cause gastrointestinal side effects including nausea, constipation, and dark stools, particularly at higher doses or with poorly tolerated forms. The microencapsulated ferrous fumarate in element3 Rise is specifically chosen to minimise these effects — the lipid coating delays release until the small intestine, reducing direct contact between iron and the upper gut lining where most discomfort originates. Iron should not be taken in excess of requirements without confirmed deficiency, as very high intake can be harmful. Always confirm iron status with a ferritin blood test before taking high-dose iron.

What are iron deficiency symptoms?
Iron deficiency symptoms range from subtle to severe depending on how depleted stores become. Early signs include persistent fatigue that doesn't resolve with rest, brain fog, difficulty concentrating, and low mood. As deficiency progresses, symptoms may include pale skin, pale inner eyelids, brittle or spoon-shaped nails, shortness of breath during exercise, and increased susceptibility to infections. Importantly, ferritin (stored iron) can be low enough to cause these symptoms before haemoglobin falls below the clinical threshold for anaemia — meaning standard blood tests may miss the issue.

What form of iron is in the element³ blend?
element3 Rise uses microencapsulated ferrous fumarate. Ferrous fumarate is a well-established iron salt with one of the highest elemental iron contents of any common form (around 33%), meaning a smaller dose delivers more usable iron. The microencapsulation — a thin lipid coating around each particle — protects the iron during transit through the stomach and delays release until it reaches the small intestine, where absorption is most efficient. This is the engineering that makes the difference: it reduces the GI side effects, taste issues, and mineral interactions that make many women discontinue iron supplementation, while preserving the bioavailability that ferrous fumarate is known for.

What are the symptoms of iron deficiency in women?
The most common symptoms of iron deficiency in women include persistent fatigue that doesn't improve with rest, brain fog, difficulty concentrating, pale skin or inner eyelids, brittle nails, and increased susceptibility to infections. Many women experience these symptoms well before they meet the clinical threshold for iron deficiency anaemia.

[ 07 ] In the Protocol

Where Iron (as Ferrous Fumarate) sits in the element3 Protocol

In element3 Rise (AM Formula), iron at 9mg as microencapsulated ferrous fumarate supports normal oxygen transport and energy production. It works alongside Vitamin C, which supports iron absorption, plus Vitamin B12 and Folate, which support normal red blood cell formation. Taken in the morning, iron is kept separate from the zinc and magnesium in element3 Rest to avoid absorption competition.
