Lactoferrin vs. Colostrum: What's The Difference?

Key Takeaways:

• Lactoferrin Does Much Of The Work Colostrum Is Known For: It is one of the most researched proteins found in colostrum, particularly for humans. Lactoferrin helps establish the gut barrier, immune system, and iron absorption process in infancy, and it continues to play a role in wellness throughout life.*
• Source Changes How Much Lactoferrin You're Getting: Most colostrum supplements are derived from cows, and cow colostrum contains a measurably lower concentration of lactoferrin than what the human body produces on its own. A label can say "colostrum" while still delivering a relatively small amount of this specific protein.
• Bioidentical Lactoferrin Offers A More Direct Route: Human-identical lactoferrin, made through precision fermentation, is built to match the exact protein your body already produces. It is also dairy-free and cruelty-free, so we leave more cow colostrum for the baby cows.

If you've spent any time researching gut health or colostrum supplements, you've probably noticed that "lactoferrin" shows up in almost every product description. The two terms are often paired together, so it's easy to assume they mean the same thing. They don't. Colostrum is the first milk mammals produce after birth, and lactoferrin is one specific protein found within it. Knowing how the two relate, and where they diverge, matters if you're comparing supplement options and want to know what you're paying for.

We have a stake in this, so read us accordingly. Palisade makes a lactoferrin supplement. But the reason this comparison is worth 1,200 words is that the label conventions in this category genuinely obscure what you're buying, and most people paying for colostrum have no idea how little lactoferrin is in the tub.

Colostrum vs. Lactoferrin: How The Two Are Related

Colostrum is the first milk mammals produce in the days right after birth, and it's a dense mix of immunoglobulins, growth factors, proteins, vitamins, and minerals. Its job is to get a newborn through its first week. That's worth holding onto, because everything colostrum supplements are sold on comes from research into a substance designed for an entirely different body than yours.

Is Lactoferrin The Same As Colostrum?

Colostrum is the first breast milk produced by mammals for their newborns, and it contains hundreds of naturally occurring compounds, and lactoferrin is one of those crucial compounds. It is also present in mature breastmilk, saliva, and tears, though its concentration is highest in colostrum (Kowalczyk et al., 2022). Because lactoferrin exists inside colostrum rather than being a wholly separate substance, the two terms are connected, but connected doesn't mean interchangeable.

That said, a colostrum supplement provides a mixture of these compounds together, in amounts that shift depending on how the colostrum was sourced and processed. Meanwhile, a lactoferrin supplement isolates that one protein and gives it to you directly, without the surrounding matrix. Those are two different bets. Colostrum asks you to take a large amount of a broad mixture and hope the protein you came for is in there at a useful level. An isolated lactoferrin supplement tells you exactly how much of that protein you're getting per serving. If lactoferrin is what you're after, the second approach is the one that lets you know what you bought.

Does Colostrum Contain Lactoferrin?

So, is lactoferrin in colostrum? Yes, colostrum naturally contains lactoferrin, and it's one of the most important proteins within it, especially for humans. Lactoferrin binds and transports iron, helps establish a newborn's gut barrier, and supports early immune development.* That role doesn't end at infancy. Research describes lactoferrin as a multifunctional protein with relevance across the human lifespan, involved in ongoing iron regulation, gut barrier maintenance, and immune signaling well into adulthood (Kowalczyk et al., 2022).* That combination of iron, gut, and immune involvement is part of why lactoferrin draws so much research attention on its own, separate from the broader colostrum conversation.

Why Lactoferrin Matters After Infancy

Here's the part nobody tells you. Lactoferrin doesn't just carry iron. It manages how your body takes iron in and where it goes, which matters more the further you get from infancy, and it matters more for women than for men. You lose iron every month. Most men don't. That's why a woman can eat well, take a multivitamin, and still show up to a blood draw with ferritin in the basement.

Ferritin is your stored iron, the reserve tank. It's the number that explains why you're exhausted at 3 PM when your hemoglobin came back normal, and it's the number most people never think to ask for. Lactoferrin is how your body manages that reserve.* Which is the whole reason we built around it.

Why Sourcing Matters: Cow Colostrum vs. Human Lactoferrin

Most colostrum supplements on the market are derived from cows, largely because bovine colostrum is easier to collect at scale than any human source. The tradeoff is concentration. Lactoferrin content in cow colostrum is measurably lower than the amount present in human colostrum, and it declines further once collection moves from colostrum to mature milk (Jańczuk et al., 2023).* That means a colostrum supplement can list "colostrum" prominently on its label while still offering a relatively small, and often inconsistent, amount of the specific protein most associated with lactoferrin's studied benefits.

This isn't a flaw unique to any one brand. It's a structural reality of sourcing lactoferrin from a species whose colostrum was built for a different purpose entirely: growing a calf, not supporting a human gut, immune system, or iron levels. If lactoferrin is what you're specifically after, the concentration gap between cow and human sources is worth factoring into the comparison.

Bioidentical Lactoferrin: A More Direct Path

Bioidentical lactoferrin offers a convenient way around the sourcing gap altogether. Rather than extracting the protein from cow colostrum, it's made through precision fermentation. In plain terms: yeast cells are taught to produce lactoferrin identical to the kind the human body makes. No cows, and to answer the question everyone asks next, no humans either. Your body recognizes it as its own protein rather than a foreign one, which is not a small distinction. In a head-to-head trial against bovine lactoferrin, people taking effera™ developed no antibodies against the protein. The people taking bovine lactoferrin did.*

This approach also removes some practical friction. Bioidentical lactoferrin can be produced without dairy and without collecting colostrum from cows or their calves, which makes it both dairy-free and cruelty-free by design. For anyone who has considered colostrum but hesitated because of the sourcing, or who avoids dairy for other reasons, that distinction is often the deciding factor. At Palisade, this is the whole formula. Two heart-shaped blackberry gummies deliver 100mg of effera™ bioidentical lactoferrin, the same dose used in a published case series in active women with persistently low iron, where ferritin and serum iron both rose with no GI side effects reported.* Alongside it: AstraGin® to help the gut absorb what you're taking, and Bacillus coagulans Unique IS-2® for the live layer behind the barrier. The complete formula is backed by 16 completed adult human clinical trials across those three ingredients.

No dairy, no cow, no scoop. We leave the cow colostrum for the baby cows.

What To Consider Before Choosing A Supplement

Here are a few details worth checking before browsing colostrum and lactoferrin products:

• Source: Note whether the lactoferrin or colostrum is bovine-derived or produced through fermentation, and whether that source fits a vegan or vegetarian diet, since bovine-derived options are animal-based while fermentation-derived versions are not.
• Concentration: This tells you how much lactoferrin, specifically, is in each serving, not just how much "colostrum" appears on the label.
• Processing: Heat treatment and filtration can destroy active protein before it ever reaches you. This is also why most lactoferrin can't be made into a gummy. Bovine-sourced lactoferrin degrades under the heat the process requires. Bioidentical lactoferrin survives it, which is the reason this format exists at all.
• Serving Size and Format: A scoop you have to mix is a scoop you'll skip by week three. Check what a full serving actually requires of you, and check that the lactoferrin amount is stated per serving rather than buried in a proprietary blend.
• Third-Party Testing: Independent verification of purity and potency adds a layer of confidence that a label alone can't.

Run a colostrum tub and a lactoferrin supplement through that list and the difference stops being philosophical. One will tell you the lactoferrin per serving. The other usually can't, because it varies batch to batch depending on the cow.

One more thing worth setting expectations on: this is a daily-consistency ingredient, not a fast one. Two gummies a day, any time of day, and give it 90 days before you judge it. Iron stores rebuild slowly no matter what you take. If iron and ferritin levels are your priority, Palisade’s Lactoferrin Gummies can be used alongside your iron supplement or an iron-rich diet. Continue taking Lactoferrin Gummies daily to maintain your results.*

Final Thoughts

Here's the short version. Colostrum's reputation rests largely on one protein, and lactoferrin is that protein. It's what builds the gut barrier, trains the immune system, and moves iron where it needs to go. Cow colostrum holds far less of it than human colostrum does, in a form your body reads as foreign, which means scoops of the wrong thing to get a little of the right one.

Bioidentical lactoferrin skips the detour. Same protein your body already makes, made without a cow, at an amount printed on the label. That's the whole argument, and it's why we built Palisade around it.

Frequently Asked Questions About Lactoferrin vs. Colostrum

Where does supplemental lactoferrin typically come from?

Most lactoferrin supplements are derived from bovine milk, though bioidentical, fermentation-derived versions are also available. Check the label and source information before choosing a product.

Is lactoferrin found only in milk?

No. Lactoferrin is also present in saliva and tears, though milk and colostrum contain it in far higher concentrations.

Is lactoferrin a probiotic?

No. Lactoferrin is a protein, while probiotics are live microorganisms. The two are different categories of ingredients, even though both sometimes appear in gut-health formulas. However, lactoferrin is considered a prebiotic that supports the growth of probiotic bacteria in the digestive system (Kowalczyk et al., 2022).*

Can lactoferrin and colostrum be taken together?

Some routines include both, since the two aren't mutually exclusive. Individual needs vary, so it's worth speaking with a healthcare provider before combining supplements, especially alongside any medication.

Does processing affect colostrum supplements?

Processing methods can influence the composition of a colostrum product. Factors such as heat treatment and filtration may affect certain naturally occurring components, making this information useful when comparing options. This is why bovine colostrum and bovine lactoferrin can’t effectively be used in a gummy form. The dose is too large, and the ingredient is too unstable under high temperatures.

What should you look for on a lactoferrin supplement label?

Check the lactoferrin amount per serving, the source (bovine vs. bioidentical), the format, and whether the product has been third-party tested for purity and potency.

Can vegetarians use lactoferrin or colostrum supplements?

Traditional bovine-derived lactoferrin and colostrum typically come from animals, so suitability depends on your approach to a vegetarian diet. Checking the source and other ingredients can help determine whether a product fits your personal dietary preferences. Ours are vegan and dairy-free.
