IronKind

30 Servings (60 Capsules)
Powered by lactoferrin and prebiotics.
From Milk

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.
  • More affordable and scalable
  • 100% cruelty-free
  • Sustainable for the planet
  • Better for you

Prebiotics

Prebiotics are fibers that feed the good bacteria in your gut, helping strengthen digestion, immunity, and overall health. They're naturally found in foods like fruits, vegetables, and grains.

How prebiotics help you feel your best:
  • Strengthen digestion
  • Support immune health
  • Improve nutrient absorption
  • Balance gut bacteria
  • Boost overall vitality
  • Naturally improves iron absorption
  • Gentle on the gut (no nausea or bloating)
  • Boosts and sustains energy

MONTH 1
Building the

MONTH 2
Boosting energy

MONTH 3
Strengthening

How it works

1. Supports gut-friendly iron absorption
Lactoferrin binds to free iron, preventing it from reaching harmful bacteria that thrive on iron and cause gut issues like bloating and discomfort.
2. Nourishes good bacteria
Prebiotics feed and support beneficial bacteria
in your gut, promoting a healthy, balanced microbiome for improved digestion and overall gut health.
3. Fuels energy levels
Lactoferrin helps your body absorb iron, which makes hemoglobin to carry oxygen to your brain and muscles. This supports energy, growth, and muscle function.

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.

Clinical Trials

Lactoferrin is clinically proven to support iron absorption, with fewer side effects than traditional iron supplements.

Study 1

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

greater
improvement
in hemoglobin
concentrations1

greater
improvement
in serum iron
levels2

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

Lactoferrin is clinically proven to have fewer gastrointestinal side effects.3

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.
