Here’s something beautiful and often overlooked: all mammals produce colostrum. From horses and humans to elephants, whales, and yes, of course — cows. This first milk is rich in life-giving immune factors and growth compounds that jump-start the health and resilience of a newborn.
But what’s truly remarkable is that cows are considered "universal donors" when it comes to colostrum. Bovine colostrum can safely be used by other mammals—including humans—because it’s so biocompatible. That’s why supplementing with high-quality bovine colostrum, like ProColostrum LD, can provide essential immune and gut health support across species.
Recent Research
A recent study out of the University of Glasgow focused on mare colostrum and foal health, but the message is crystal clear for us, too: colostrum quality directly affects immune strength—and early immunity has lasting impact.
The researchers found that foals who didn’t get enough high-quality colostrum were much more vulnerable to illness. Even more surprising, the larger and seemingly healthier the foal, the more at risk they were if they didn’t get enough immune support early on. It’s a reminder that immune needs can’t be assumed based on how we look on the outside. Robust immunity has to be built from within—and it starts in the gut.
That’s where ProColostrum LD comes in.
Our formula delivers professional-grade bovine colostrum with a unique liposomal delivery system, ensuring it survives digestion and actually reaches the small intestine where it can do the deep work of healing, nourishing, and defending.
The study used a tool called a Brix refractometer to measure how antibody-rich each mare’s colostrum was. Even small increases in colostrum quality led to significant boosts in foal immunity (measured through IgG levels in the blood). What does this mean in human terms? Higher-quality colostrum equals stronger, smarter immune function. And that’s something every body—young or old—can benefit from.
Colostrum Isn't Just For Babies
It’s also worth noting that older mares in the study produced lower-quality colostrum, similar to how aging and stress can reduce immune resilience in people. For adults navigating chronic inflammation, gut issues, or just the wear-and-tear of modern life, colostrum isn’t just for babies—it’s for anyone who wants to rebuild and protect their health at the foundational level.
What's The Bottom line?
Nature knew what it was doing with colostrum. And thanks to our "universal donors" cows and advanced liposomal delivery, we can all benefit from that first, best gift of immunity—no matter what stage of life we’re in.
The Universal Power of Colostrum: Why ProColostrum LD Supports Immune Health at Every Stage of Life
As I said before: all mammals produce colostrum. From humans and horses to elephants, whales, and yes—cows—this “first milk” is rich in immune-boosting compounds that help newborns thrive.
But what’s truly remarkable is how bovine colostrum—especially in professional-grade formulas like ProColostrum LD—can support immunity and gut health across species, including humans.
What Is Colostrum?
Colostrum is the pre-milk liquid, the first form of 'milk' produced by mammals immediately after giving birth. It’s loaded with antibodies, growth factors, and nutrients that are crucial for kick-starting a newborn’s immune system and digestive health.
This nutrient-dense fluid offers foundational support for:
Immune system development
Gut lining repair and protection
Inflammation response
Whole-body resilience
Why Bovine Colostrum Is a “Universal Donor”
Unlike other types of colostrum, bovine colostrum is considered biocompatible with many other species—including humans. That means it can be used safely and effectively as a supplement for immune and gut health in people of all ages.
Bovine colostrum contains significantly higher concentrations of immune factors—especially Immunoglobulin G (IgG)—than human colostrum, sometimes up to 40 times more. While both bovine and human colostrum share similar components and functions, bovine colostrum stands out for its potency and broad-spectrum immune benefits.
In fact, cows are considered universal donors—their colostrum can be safely used by other mammals, including humans, making it an ideal supplement to support immune and gut health across species.
ProColostrum LD takes this even further by using a liposomal delivery system to ensure the colostrum survives digestion and reaches the small intestine—where it can do the real work of healing and protection.
Colostrum Quality Directly Impacts Immune Strength
A recent study out of the University of Glasgow examined how the quality of mare colostrum affected foal immunity. The findings have clear implications for us, too:
Foals who didn’t receive high-quality colostrum were significantly more vulnerable to illness.
Surprisingly, larger and seemingly stronger foals were at greater risk when they lacked immune support—proving that external appearance doesn’t always equal internal strength.
In human terms: just because someone looks healthy doesn’t mean their immune system is functioning optimally. True immunity starts in the gut—and that’s where colostrum plays a critical role.
Measuring Colostrum Quality: What the Science Says
Researchers used a Brix refractometer to evaluate the antibody concentration (IgG levels) in each mare’s colostrum. Even small increases in quality led to meaningful boosts in immunity for the foals.
For humans, that translates to this simple truth:
Higher-quality colostrum = stronger immune defense and better health outcomes.
Colostrum Isn’t Just for Babies—It’s for Anyone Who Wants to Thrive
The study also found that older mares produced lower-quality colostrum, mirroring what we know about human aging: immune function and gut health decline over time, especially with stress, poor diet, and chronic inflammation.
That’s why adults with autoimmune conditions, leaky gut, or fatigue are increasingly turning to colostrum supplementation. It’s not just about recovery—it’s about rebuilding and protecting from the inside out.

Frequently Asked Questions (FAQ)
What is colostrum, and why is it important?
Colostrum is the first milk produced by mammals after giving birth. It’s rich in antibodies and immune-supporting nutrients that help build a strong immune system and healthy gut.
Can humans take bovine colostrum?
Yes! Bovine colostrum is considered a “universal donor” because it’s highly biocompatible with humans and other mammals. When taken in supplement form, it can help support gut health, immunity, and inflammation response.
Is ProColostrum LD safe for everyday use?
Absolutely. ProColostrum LD is made with professional-grade bovine colostrum and uses a liposomal delivery system for maximum absorption and safety. It’s suitable for daily immune and gut support for both adults and children.
What makes ProColostrum LD different from other colostrum supplements?
ProColostrum LD uses a unique liposomal delivery system, which protects the colostrum as it passes through the digestive tract. This ensures more active ingredients reach the small intestine—where they can do their work.
Who can benefit from taking colostrum?
Anyone looking to support or rebuild their immune system, gut health, or overall vitality. This includes people dealing with:
Chronic gut issues (like leaky gut or IBS)
Autoimmune conditions
Recovery from illness or antibiotic use
Aging-related immune decline
Everyday stress and inflammation
Final Thoughts: Nature’s First and Finest Immune Booster
