Description

Lactoferrin is an iron-binding protein found naturally in milk, part of the same protein family as transferrin, which carries iron in the blood. Double Wood Lactoferrin provides 250mg of bovine lactoferrin per 2-capsule serving to support healthy immune function, normal iron transport and utilization, and a balanced intestinal environment.* It is a concentrated milk protein, not a conventional elemental iron supplement.

One serving is 2 capsules (125mg each), with 30 servings per bottle, a one-month supply. Every batch tested. Third-party tests by ISO/IEC 17025 accredited labs. COAs published openly. For a broader gut-wellness routine, pair Lactoferrin with Digestive Enzymes. Lactoferrin supports a balanced intestinal environment, while Digestive Enzymes support the normal breakdown of proteins, fats, and carbohydrates around meals.*

The Science Behind Bovine Lactoferrin

What lactoferrin is. Lactoferrin is an iron-binding glycoprotein in the transferrin family, the same family as the protein that carries iron in the blood. It occurs naturally in milk, with especially high levels in colostrum, and is also found in other body fluids. Supplements typically use bovine lactoferrin, which is similar in structure to the human form.

Lactoferrin and immune markers in a small human study. This research is provided for general ingredient background and does not establish that this product will produce the same results. In a small study published in Nutrition Research (Mulder et al., 2008), 8 healthy men took placebo, then 100mg, then 200mg of bovine lactoferrin daily, one week each. After the 200mg phase, researchers measured increased T-cell activation, a marker of immune activity, and higher antioxidant capacity in the blood. Most other immune measures did not change. The study was very small, had no separate control group, and did not test this product.*

Iron binding, not iron supplementation. Lactoferrin’s defining feature is that it binds iron. That is why it is studied for its role in normal iron transport. It is different from a conventional iron supplement, which provides elemental iron. Much of the published research on lactoferrin and iron involves people with low iron, so those findings should not be assumed to apply to everyone.

Frequently Asked Questions

What is lactoferrin and what does it do?

Lactoferrin is an iron-binding protein found naturally in milk. It supports healthy immune function, normal iron transport and utilization, and a balanced intestinal environment.* Double Wood’s formula provides 250mg of bovine lactoferrin per 2-capsule serving.

How much lactoferrin is in each capsule?

One serving is 2 capsules, providing 250mg of lactoferrin, so each capsule contains 125mg. Take 1 serving per day, with or without food. Each bottle provides 30 servings, a one-month supply.

Is lactoferrin the same as an iron supplement?

No. Conventional iron supplements provide elemental iron. Lactoferrin is a milk protein that binds iron and supports normal iron transport and utilization.* If your healthcare provider has recommended iron for low iron levels, lactoferrin is not a substitute for that care.

What supplements pair well with lactoferrin?

Digestive Enzymes are the pairing for Lactoferrin. Lactoferrin supports healthy immune function and a balanced intestinal environment, while Digestive Enzymes support the normal breakdown of proteins, fats, and carbohydrates around meals.* This is complementary routine support, not a claim that either product increases the effect of the other. Take enzymes with meals and Lactoferrin according to its own label.

Is lactoferrin dairy-free or vegetarian?

No. Lactoferrin is derived from bovine milk, and the capsule is made from gelatin, so this product is not dairy-free, vegetarian, or vegan. Do not use it if you have a milk-protein allergy.

Are there side effects of lactoferrin?

Some people may experience mild digestive discomfort. Do not use if you have a milk-protein allergy, or if you are pregnant, nursing, or under 18. Consult your physician before use, especially if you are being evaluated or treated for low iron or another medical condition, and discontinue use if any adverse reaction occurs.

Is Double Wood Lactoferrin third-party tested?

Yes. Every batch tested. Third-party tests by ISO/IEC 17025 accredited labs. COAs published openly.

Overall rating: 5.0 / 5 from 2 reviews.

Great quality

"Overall happy with this product so far, about half way through my 30 day supply. No side effects or irritation which I am prone to. Skin is clearing up and gut health has improved."

— April D. (5/5)

This is the only iron my body can handle

"I have had a anemia for a long time because my body doesn't absorb iron properly. I may have something called iron pill gastritis. I've been searching for a form of iron that my body will absorb. I've only be taking the bioferrin/lactoferrin for about a month, but I know I feel much better. I will have my blood numbers checked again in a couple of months to see what they look like. I'm very hopeful."

— Judy M. (5/5)

Q&A

Is your lactoferrin free dried?
Our Lactoferrin is the patent formula Bioferrin 2000. Bioferrin is typically freeze-dried during its production. This method helps preserve its bioactivity and ensures the product retains its functional and nutritional properties. Freeze-drying is commonly used for high-quality lactoferrin products to maintain their purity and efficacy.
There seems to be a lot of confusion as to if this supplement contains iron or not. Thats very important. The other question has an answer saying it is bioferrin 2000 but nothing in the product page indicates that. The product page also alludes to that it does contain iron. So does it contain iron or not?
Bioferrin 2000 (lactoferrin) is a bioactive protein found in milk that can bind iron but is not the same as elemental iron typically found in iron supplements. If the product contains Bioferrin 2000, it indicates that the supplement supports iron metabolism but doesn’t necessarily contain iron itself. However, lactoferrin can help with iron absorption. Lactoferrin or Bioferrin is associated with iron because it binds iron, but it doesn’t supply iron directly.
I previously asked what percentage of this is saturated with iron, but I would also like to know the percent of actual lactoferrin this contains.
No, Bioferrin 2000 does not contain saturated iron. Bioferrin 2000 is a trademarked bioactive protein derived from bovine colostrum, specifically lactoferrin, which is a glycoprotein known for its ability to bind and transport iron. Lactoferrin is involved in iron metabolism but does not itself contain iron in a saturated form.
