1. IronKind is carefully optimized for superior iron absorption.

Traditional supplements overload your body with iron, causing bloating, nausea, and fatigue.

IronKind Takes A Different Approach:
  • Balances iron absorption naturally to work with your body, not against it.
  • Fuels sustained energy by supporting better oxygen delivery.
  • Avoids common side effects like bloating, nausea, and constipation.

2. Our breakthrough vegan formula includes lactoferrin, a powerful ingredient that supports immunity and gut health.

Lactoferrin is a protein known for supporting immunity, gut health, performance, and recovery.

It’s most abundant in colostrum, the first milk produced after birth.

IronKind is the first lactoferrin produced through precision fermentation without the use of milk.

  • Sustainable for the planet
  • Better for you

3. IronKind approaches gut health in 
three powerful ways.

Balances the
microbiome

IronKind promotes a healthy gut by supporting good bacteria and reducing bad bacteria that feed on iron, helping ease bloating, nausea, and discomfort.

Dual-action formula

IronKind works in two ways: lactoferrin locks away excess iron, while prebiotics fuel good bacteria—supporting balance, comfort, and long-term gut health.

Supports gut barrier
& absorption

By limiting harmful bacteria and inflammation, IronKind helps maintain the gut lining and boosts nutrient absorption—allowing your body to better use iron and other key nutrients.

4. Lactoferrin is clinically proven to improve iron absorption and has fewer gastrointestinal side effects.

Study 1

Lactoferrin supplementation outperforms traditional iron supplementation in women with iron deficiency:

1-2 Based on a meta-analysis of 7 clinical studies with 813 total participants (pregnant and non-pregnant women) with various iron deficiency conditions. Participants took 100 mg lactoferrin 2x/day for 1-3 months vs ferrous sulfate (Zhao et al, 2022).

Study 2

3 Based on a randomized controlled clinical trial of 100 pregnant women with iron deficiency anemia. Participants took lactoferrin for 30 days vs ferrous sulfate (Nappi et al., 2009)

5. Not only has it been clinically studied, it’s backed by experts.

Lactoferrin

FE (Iron)

Lactoferrin is a protein found in milk, known for supporting immunity, gut health, performance, and recovery.

Milk does not contain ACTIVE lactoferrin as it is denatured in the pasteurization process. Most abundant in colostrum, the first milk produced 
after birth.

IronKind has the first vegan-certified lactoferrin produced through precision fermentation without the use of milk.

About 80% of your daily iron needs come from your body recycling your red blood cells, whereas 20% comes from your diet. If your regular diet lacks iron, consult your physician to see if IronKind can replace or work together with your iron supplement.

Results that speak for themselves

I’ve always had been told by doctors that my iron levels were low. Since I started taking IronKind regularly, I noticed that my daily brain fog has gone away and I’ve been able to focus throughout the day. I no longer have mid day energy crashes and I wake up clear headed now. IronKind has helped me tremendously and I’m definitely going to keep taking it!

I had been searching for a bio-compatible lactoferrin product for years due to health reasons. From the beginning, I’ve been watching this company grow to create this wonderful first-of-its-kind product and I couldn’t be happier!

Verified Buyer

I've had anemia for several years due to heavy periods and vegetarian diet. My body struggled with iron absorption. I learned about lactoferrin this year. So I researched to see if I could find a lactose free kind. I was so relieved to find Intentional. I have since completed one bottle so far. I'm happy to say, I had my first normal period in years. I can't wait to get blood work to check my iron levels next month. Thank you Intentional!!

I feel great after taking IronKind for only 14 days. I usually feel tired on the daily, not having enough energy to get through my 9-5. But taking this makes me feel more awake throughout the day !! I wasn’t sure if IronKind lactoferrin was for me at first, but trying it out changes my view on it! Would definitely recommend giving it a try!

Your questions, answered

  • When should I take IronKind?

    IronKind can be taken anytime of day, but for optimal absorption, we recommend taking it before a meal on an empty stomach.  If discomfort occurs, try taking IronKind with a meal.

  • What is Lactoferrin?

    Lactoferrin is a multifunctional protein found in milk. It is known for its benefits to the immune system, gut health, performance, and recovery. It is particularly abundant in colostrum, the first milk produced by mammals in the first few days after birth.

  • How is IronKind vegan if it contains lactoferrin, a milk protein?

    We’ve used groundbreaking precision fermentation technology to produce vegan lactoferrin by harnessing the power of microbes. In the same way that kombucha or kefir are brewed, our specially engineered microbes ferment sugars to produce vegan lactoferrin. 

  • How old do my kids need to be to take IronKind?

    We know Lactoferrin, IronKind's hero ingredient, is used in some infant formulas.

    However, always recommend consulting with a healthcare provider for anyone wanting to take IronKind under the age
of 18.

    Children under the age of 2 years should not take IronKind.

  • Can I take IronKind when pregnant or nursing?

    IronKind is made with precision-fermented lactoferrin and prebiotics to support healthy iron levels and overall well-being. Studies suggest lactoferrin can help improve hemoglobin levels, reduce inflammation, and support immune function during pregnancy and postpartum.

    While these benefits are promising, every pregnancy and postpartum journey is unique. We recommend consulting with your healthcare provider before adding IronKind to your routine.​

  • Can I take IronKind with my iron supplement?

    While IronKind can be taken with traditional iron supplements, some clinical studies indicate that lactoferrin supplementation alone can outperform traditional iron supplementation.

    A meta-analysis of 7 clinical studies looked at pregnant and non-pregnant women with various iron deficiency conditions taking lactoferrin vs ferrous sulfate (Zhao et al, 2022).  Participants with iron-related deficiencies saw a 2x greater improvement in hemoglobin concentrations and an 8x greater improvement in serum iron levels.

    While these benefits are promising, every health journey is unique. We recommend consulting with your healthcare provider before adding IronKind to your routine.​

  • What is the prebiotic in IronKind?

    Our prebiotics are mannan polysaccharides. These are larger than the mono and oligosaccharides categorized under FODMAPs.  Beneficial gut species like Bacteroides can utilize these mannans.

  • Why take IronKind over Colostrum?

    IronKind is a great alternative to bovine colostrum. It has many of the same functions as bovine colostrum, and is vegan. Despite its health benefits, bovine colostrum has several drawbacks:

    Unethical Animal Welfare: The collection of colostrum often involves separating calves from their mothers shortly after birth, causing distress to both animals.

    Supply Constraints: The calving cycle of dairy cows limits the production of bovine colostrum, leading to an unstable supply and difficulty meeting growing demand.

    High Environmental Impact: The dairy industry, including the production of bovine colostrum, has a significant negative impact on the environment, contributing to greenhouse gas emissions, water consumption, and land use.

Feel the difference with balanced iron and a stronger gut.
