What ingredients are in Iron Repair Plus and how are they sourced?

Iron Repair Plus is intentionally formulated with clean, minimal ingredients designed to support healthy iron levels without unnecessary additives.

Each capsule contains:

• 20 mg elemental iron (from natural iron concentrated from non-GMO, grass-fed & finished bovine spleen)

• 25 mcg Methylcobalamin (active vitamin B12)

• 50 mcg 5-MTHF (active folate)

Why we use this source of iron

Iron Repair utilizes natural animal-sourced iron from bovine spleen, which is naturally rich in the iron-containing proteins the body uses to support healthy ferritin levels and hemoglobin production.

Our bovine spleen is sourced from non-GMO, grass-fed and finished cattle raised in the pristine pastures of Argentina, a region known for its strong animal welfare standards and clean agricultural practices.

Why we use methylated B12 and folate

Iron Repair Plus uses the bioactive forms of B vitamins that the body can use immediately.

Many supplements use cyanocobalamin (vitamin B12) and folic acid, which must first be converted by the body into their active forms before they can be fully utilized.

However, research suggests that 40–60% of the population carries genetic variations in the MTHFR gene, which may reduce the body’s ability to efficiently convert folic acid into its active form. Because of this, some individuals may benefit from receiving folate in its already active form.

Iron Repair Plus instead provides:

• Methylcobalamin – the active form of vitamin B12

• 5-MTHF (methylated folate) – the active form of folate used by the body

These bioactive forms are often preferred because they do not require the same conversion steps as synthetic forms like cyanocobalamin and folic acid.

By providing these nutrients in their methylated, ready-to-use forms, Iron Repair Plus helps support healthy red blood cell production, hemoglobin formation, and overall iron metabolism.

Clean label ingredients

Iron Repair Plus does not contain the synthetic fillers, artificial colors, or unnecessary additives that are common in many iron supplements.

Instead, the formula contains only:

• Natural iron concentrated from grass-fed bovine spleen

• Methylcobalamin – the active form of vitamin B12

• 5-MTHF (methylated folate) – the active form of folate used by the body

• L-Leucine, a naturally occurring amino acid used to support capsule flow

• Bovine gelatin capsule

This simple formulation helps ensure Iron Repair remains a clean-label iron supplement designed for purity and effectiveness.

Why do you use L-Leucine?

L-Leucine is a naturally occurring essential amino acid that is commonly found in protein-rich foods. For example, a single chicken breast contains roughly 2,500 mg of L-Leucine, while each Iron Repair capsule contains only 50 mg.

As a natural product, our iron powder tends to be a bit 'sticky' in our encapsulation machines, so we include a small amount of L-Leucine simply to help the natural iron powder flow smoothly into capsules during manufacturing. This allows us to maintain a clean, minimal formula without relying on the heavy binders and lubricants commonly used in tablet manufacturing.

Many conventional supplements use inexpensive flow agents such as magnesium stearate, titanium dioxide, polyethylene glycol, and other synthetic fillers. While these ingredients are often considered “industry standard,” they are typically added purely for manufacturing convenience rather than nutritional value.

At Three Arrows Nutra, we prefer to use simple, recognizable ingredients whenever possible. L-Leucine allows us to keep the formula clean while avoiding the long list of unnecessary additives commonly found in conventional supplements.

How should I take Iron Repair for best results?

Iron Repair is designed to be simple and flexible to take.

Unlike many traditional iron supplements that must be taken on an empty stomach, Iron Repair can be taken with or without food, making it easy to incorporate into your daily routine.

Because every person’s iron levels and causes of iron deficiency are different, there is no one-size-fits-all approach to restoring healthy iron stores. The amount of iron needed to support ferritin and hemoglobin levels can vary depending on your current iron status.

Iron Repair uses natural iron concentrated from non-GMO grass-fed bovine spleen, which many individuals find easier to tolerate than traditional synthetic iron supplements.

When you purchase Iron Repair, you also receive access to our Warrior Success Tools. These resources help guide you through:

• how to take Iron Repair for best results

• suggested dosing guidance based on recommendations from the American Society of Hematology

• strategies for supporting ferritin restoration and iron recovery

These tools are designed to help you stay consistent and successful on your Iron Repair journey toward rebuilding healthy iron levels.

Of course, this is NOT medical advice. It's important to discuss your iron requirements and any new supplements with your doctor...we encourage  you to share Iron Repair with your doctor.  Many don't know Iron Repair is an option and once they learn about it they are able to help many of their other patients with this knowledge!

How long does it take iron supplements to start working?

Restoring healthy iron levels takes time, because your body must gradually rebuild its iron stores and produce new red blood cells.

Red blood cells have a lifespan of about 90 days, which means it can take several weeks to months for iron levels and ferritin stores to improve.

Many people begin noticing improvements in energy, focus, and overall well-being within a few weeks, but rebuilding healthy ferritin and hemoglobin levels typically requires consistent supplementation for at least 90 days.

For this reason, we recommend taking Iron Repair consistently for a minimum of three months while monitoring your iron levels with your healthcare provider.

The good news is that Iron Repair is designed to be gentle and easy to tolerate, so you can focus on restoring your iron levels without the stomach upset often caused by traditional iron supplements.

And for added peace of mind, every purchase is backed by our 90-day 100% Happiness Guarantee.

How much elemental iron is in each Iron Repair capsule?

Each capsule of Iron Repair provides 20 mg of elemental iron from natural animal-sourced iron concentrated from non-GMO, grass-fed and finished bovine spleen.

Why the source of iron matters

Iron exists in two main forms in both food and supplements:

• Animal-sourced iron

• Plant-based or synthetic iron compounds

Animal-sourced iron is generally considered the most bioavailable form because the body can recognize and absorb it efficiently in its natural structure.

For this reason, people working to improve low iron or low ferritin levels are often encouraged to include iron-rich foods like red meat in their diet.

The challenge with dietary iron

While foods like red meat contain bioavailable iron, the amount per serving is relatively small.

For example:

• 1 serving of beef ≈ 2.6 mg of iron

• 1 serving of chicken ≈ 0.9 mg of iron

Even organ supplements such as desiccated liver contain only modest amounts of iron.

For example:

• 1 serving desiccated liver (6 capsules) ≈ 2.5 mg of iron

Iron Repair provides concentrated natural iron. Iron Repair is made from ultra-filtered and hydrolyzed bovine spleen powder, which allows the iron-containing proteins to be concentrated into a convenient capsule.

This means you can receive significantly more iron without needing to consume large quantities of meat or organ supplements.

1 capsule of Iron Repair = 20 mg of elemental iron

This concentrated natural iron source helps support individuals working to rebuild iron stores, ferritin levels, and healthy hemoglobin production.

What is Iron Repair Plus?

Iron Repair Simply is a clean-label iron supplement made with natural iron concentrated from non-GMO, grass-fed and finished bovine spleen. It is designed to help support healthy ferritin levels, hemoglobin production, and overall iron status without the harsh side effects often associated with traditional synthetic iron supplements.

Who should take Iron Repair Plus?

Iron Repair Plus may be helpful for individuals who:

• have been told they have low iron or low ferritin levels

• want to support healthy hemoglobin production

• experience symptoms commonly associated with iron deficiency

• prefer a natural, clean-label iron supplement

• have difficulty tolerating traditional iron supplements

Always consult your healthcare professional before beginning supplementation.

How is Iron Repair Plus different from traditional iron supplements?

Many conventional iron supplements use synthetic iron salts, which can be difficult for some people to tolerate and may cause digestive discomfort such as nausea, constipation, or stomach upset.

Iron Repair Plus takes a different approach. It provides natural animal-sourced iron concentrated from non-GMO, grass-fed and finished bovine spleen, a natural source of iron-containing proteins that support healthy ferritin levels, hemoglobin production, and overall iron status.

It’s important to note that Iron Repair is not the same as standard desiccated spleen or organ supplements.

Many organ supplements simply contain dried organ powder and typically provide very small amounts of iron. While they can be nutritious whole-food supplements, they are not designed to deliver meaningful levels of iron for people working to restore low iron or ferritin levels.

Iron Repair uses bovine spleen as the source material, but then goes a step further by concentrating the iron-containing proteins through a specialized filtration and hydrolysis process.

This allows Iron Repair Plus to provide 20 mg of elemental iron per capsule, offering significantly more iron than typical organ supplements while maintaining a clean-label, natural iron source.

The result is a concentrated natural iron supplement designed to support healthy iron levels without the harsh side effects often associated with synthetic iron supplements.

Can Iron Repair Plus be taken with food?

Yes. Iron Repair Plus can be taken with or without food, which may help make iron supplementation easier for people who experience stomach discomfort with traditional iron supplements.

Always follow the dosage instructions provided on the label or by your healthcare professional.

Is Iron Repair Plus safe to take during pregnancy?

Iron Repair Plus may be used during pregnancy when iron supplementation is recommended by your healthcare provider.

Iron needs increase significantly during pregnancy because your body must support both your own blood supply and your baby’s development.

Iron Repair provides natural iron concentrated from non-GMO, grass-fed and finished bovine spleen, designed to support healthy ferritin levels, hemoglobin production, and overall iron status.

Many women experience iron deficiency or low ferritin during pregnancy, which is why doctors often recommend iron supplementation to support healthy red blood cell production and oxygen delivery.

If your doctor has recommended an iron supplement, Iron Repair can be a gentle, natural option that many women choose when working to restore iron levels.

A personal note from Krystal

As a mother who experienced severe anemia during multiple pregnancies, I often wish Iron Repair had been available during those pregnancies. Our goal at Three Arrows Nutra is to provide iron support that is both effective and easier to tolerate during important seasons of life like pregnancy.

Why do so many people struggle with traditional iron supplements?

Traditional iron supplements often rely on synthetic iron forms that can cause digestive side effects such as nausea, constipation, or stomach discomfort.

Iron Repair Simply uses natural iron concentrated from a whole-food source, offering a gentler option for individuals who have struggled with tolerance.

Why did you choose this form of iron?

Iron Repair uses natural animal-sourced iron concentrated from non-GMO, grass-fed and finished bovine spleen.

This source of iron naturally contains iron-binding proteins that support the body’s ability to absorb and utilize iron for important functions such as hemoglobin production and maintaining healthy ferritin levels.

Many conventional iron supplements rely on synthetic iron salts, which can cause digestive discomfort for some individuals.

By using a natural source of iron and concentrating the iron-containing proteins, Iron Repair is designed to provide meaningful levels of iron in a form that many people find easier to tolerate while supporting healthy iron levels.

Our goal when developing Iron Repair was to create a clean-label iron supplement focused on absorption, tolerance, and transparency.

Who should not take Iron Repair?

Iron supplements should only be taken when iron supplementation is appropriate.

Individuals with conditions related to iron overload or other medical conditions affecting iron metabolism should consult their healthcare provider before using iron supplements.

As with any supplement, it is important to discuss iron intake with your doctor, especially if you are pregnant, nursing, or taking medications.

What symptoms can low iron cause?

Low iron levels may contribute to symptoms such as:

• fatigue or low energy

• hair shedding or hair thinning

• shortness of breath

• brain fog or difficulty concentrating

• dizziness or headaches

• pale skin

Many people experience these symptoms when ferritin levels are low, even before anemia is diagnosed.

What is ferritin and why does it matter?

Ferritin is a protein that stores iron in the body. It reflects the amount of iron reserves available for important functions such as oxygen transport, energy production, and cellular metabolism.

Low ferritin levels are one of the most common indicators of iron deficiency.

Supporting healthy ferritin levels can help maintain normal energy, cognitive function, and overall vitality.
