Our Pure, First-Milking Grass-Fed New Zealand Colostrum:A Powerful Matrix of Bioactive Compounds and Essential Nutrients to Support Immune Health, Gut Integrity, and Cellular Regeneration
Immune-Supporting Powerhouses:
- Immunoglobulins (IgG, IgA, IgM) – Research shows these antibodies play a crucial role in supporting gut barrier function and immune defense. Studies demonstrate that IgG specifically helps maintain intestinal integrity and healthy immune responses
- Lactoferrin – This remarkable compound helps maintain a healthy gut environment by binding to iron, making it less available to harmful bacteria. Studies show it supports natural immune defenses, aids in maintaining healthy gut flora balance, benefits athletes during intense training, and helps maintain healthy inflammatory and respiratory responses. Lactoferrin content is highest in true first-milking colostrum and requires careful processing to preserve its benefits.
- Proline-Rich Polypeptides (PRPs) – These powerful immune modulators have been shown in research to help regulate immune system function and support the body's natural inflammatory response


Growth & Regenerative Factors:
- Insulin-like Growth Factor 1 (IGF-1) – Research shows IGF-1 plays a vital role in muscle recovery, tissue repair, and metabolic function
- Transforming Growth Factors (TGF) – Studies indicate these compounds support gut barrier integrity and help maintain healthy tissue repair processes
Gut Health Supporters:
- Support the growth of beneficial bacteria (Bifidobacteria and Lactobacilli) while helping maintain healthy gut flora balance
- Help maintain intestinal barrier integrity by supporting tight junction proteins and the gut's protective mucus layer
- Work alongside lactoferrin, immunoglobulins, and PRPs to create a comprehensive approach to gut and immune health


Essential Nutrients:
- Complete profile of vitamins, minerals, and other nutrients that support overall health and vitality

Be Wary of Fake Colostrum and False Advertising From Many Brands.
Our Colostrum is The Real Deal.
Colostrum has skyrocketed in popularity, becoming one of the most sought-after supplements in natural health. While over 3,500 human studies demonstrate colostrum’s remarkable benefits for gut health, cellular regeneration, and immune function, there’s something critical you need to know:

The "Fake Colostrum" Problem

The IgG Deception
- The processing has denatured the other crucial compounds
- The IgG itself has been damaged by high-heat treatment
- Other key bioactive factors are missing or compromised

The Processing Problem
- Growth factors and regenerative peptides
- Proline-rich polypeptides
- Lactoferrin and immune factors
- Transfer factors
- Oligosaccharides

The "Grass-Fed" Deception
- Giving conventionally raised cows brief access to grass
- Adding grass to conventional feed
- Using standard industrial farming practices while marketing "grass-fed"


What makes our MIP New Zealand Grass Fed Colostrum different:
- True first-milking collection within 24 hours
- Low-temperature processing preserves bioactive compounds
- Controlled cold chain logistics
- Protected storage conditions
- Rigorous testing for potency and purity
- Genuine pasture-raised sourcing with documentation
- No genetically modified organisms
- Strict oversight of dairy partners
Our pristine New Zealand pastoral system allows cows to roam freely on grasslands, producing pure, clean colostrum as nature intended, without antibiotics, hormones, or toxic feed.
The difference between true first-milking colostrum from pasture-raised New Zealand cows and conventional products isn’t subtle – it affects everything from bioactive compound concentrations to your health outcomes.
The Gut Barrier:
Your Body's Critical Defense System
Your gut barrier isn’t just another organ – it’s the command center of your health, housing over 80% of your immune cells [4].
When compromised, it affects your entire body.
A damaged gut barrier (commonly called “leaky gut”) causes your digestive system, microbiome, and immune system to suffer. This can trigger:
- Body-wide inflammation
- Digestive symptoms like belly pain, gas, and bloating
- Increased risk of immune conditions
- Deep fatigue and unresolvable pain [2]
“Mounting evidence now suggests that the intestinal barrier is compromised not only in digestive disorders, but also in disorders of the central nervous system, such as Parkinson's disease, autism spectrum disorder, depression, multiple sclerosis, and Alzheimer's disease” [3].


Your Gut Barrier: Mission Control for Health
- Acts as mission control for your immune system
- Regulates what enters your bloodstream
- Maintains the delicate balance of your microbiome
The Hidden Crisis of Compromised Gut Barriers
Research reveals that compromised gut barriers are shockingly common, affecting far more people than previously thought.
Studies now link gut barrier issues to:
- Chronic inflammation and digestive disorders
- Chronic immune conditions
- Neurological health challenges
- Reduced athletic performance
- Compromised immune function
Colostrum: Nature's Most Potent Solution for Gut Barrier Health
Key Research Findings:
- A landmark double-blind, placebo-controlled study showed colostrum reduced exercise-induced gut permeability by 125%
- Research demonstrates colostrum maintains intestinal tight junction strength, specifically preserving occludin and claudin proteins
- Clinical trials show colostrum reduces intestinal permeability in athletes and patients with gut disorders
- Studies indicate colostrum helps maintain healthy zonulin levels - a critical regulator of intestinal tight junctions
Research demonstrates colostrum’s power comes from its synergistic matrix of compounds: immunoglobulins (IgG, IgA) that support barrier integrity and mucosal immunity, lactoferrin that helps maintain healthy gut flora, growth factors that support intestinal tissue health, and proline-rich polypeptides that help regulate immune responses and inflammatory balance.
Each of these bioactive compounds works together to provide comprehensive gut barrier support.

How colostrum helps your gut:
- Strengthens tight junction proteins between intestinal cells
- Supports the gut's protective mucus layer
- Helps maintain healthy inflammatory responses
- Provides immune factors that protect barrier integrity
Whether you’re an athlete pushing your limits, dealing with digestive challenges, or focused on optimal health, research suggests true first-milking New Zealand colostrum provides comprehensive gut barrier support through multiple, clinically validated mechanisms.

Learn what the science has to say about colostrum and…
Intestinal permeability (“leaky gut”):
- A double-blind, placebo-controlled study of healthy athletes examined the effect of 20 days of colostrum supplementation on gut permeability, measured by the lactulose/mannitol test and stool zonulin concentration. The use of colostrum fully resolved and even improved GI markers in the 75% of participants with irregular test results [6].
- In a double-blind, placebo-controlled, crossover protocol exploring the use of colostrum to mitigate exercise-induced intestinal permeability, those in the placebo arm experienced a 2.5-fold increase in intestinal permeability while those given colostrum buffered this rise by 80%. On top of this, colostrum decreased the effect of heat stress by 66% in an in vitro arm of the study. The authors conclude that colostrum reduced gut permeability, likely through its positive influence on temperature-induced cell death (apoptosis) [7].
- In a randomized, double-blind, placebo-controlled study of 70 hospitalized patients, colostrum supplementation led to significantly decreased endotoxin and zonulin levels, well-established markers of intestinal permeability. Additionally, incidences of diarrhea were significantly lower in the colostrum group than in the placebo group [8].
- A randomized, controlled, crossover trial of healthy men given acute doses of a non-steroidal anti-inflammatory drug, such as is commonly taken for injuries, pain, or fever, found that the group co-supplemented with colostrum experienced no increases in gut permeability as measured by lactulose/rhamnose ratios. However, those in the control group not given colostrum experienced a 3-fold increase in gut permeability during acute NSAID use. The authors state that colostrum may provide a novel approach to NSAID-induced gastrointestinal damage in humans [9].
[10]

Immune and metabolic function
- In a 12-week randomized, double-blinded, placebo-controlled study of healthy older adults, those given colostrum had lower levels of inflammatory compounds such as C-reactive protein, IL-6, and TNF-α. The authors concluded that colostrum likely led to metabolic changes that improved immune function in people between the ages of 50 to 69 years old [11].
- A double-blind, placebo-controlled crossover protocol examining the effects of 6 weeks of colostrum or placebo on 28 healthy males found a significant increase in immunoglobulin G—one of the most abundant and crucial antibodies for infection prevention—and a decrease in inflammatory markers after standardized exercise tests [11,12].
- In a randomized study of type 2 diabetic patients, 4 weeks of supplementation with bovine colostrum led to significant, gradual decreases in both 2 and 8-hour postprandial blood glucose throughout the 4-week supplementation period, along with decreases in total cholesterol and triglyceride levels [13].
- A randomized, double-blind study of 53 male runners given colostrum or a placebo for 12 weeks found that those given colostrum had a significantly lower proportion of upper respiratory tract infections (URI) and number of URI episodes. Additionally, real-time quantitative PCR testing found a significant increase in salivary bacterial load in the placebo versus the colostrum group [14].
- A double-blind, randomized, placebo-controlled study of critically ill patients explored the use of just 10 days of colostrum as part of an enteral nutrition formula. In the group receiving colostrum, researchers found significantly higher levels of the immune proteins CD4 and CD8, higher levels of lymphocytes, and much lower incidences of ventilator-associated pneumonia and C. difficile-associated diarrhea, an often life-threatening condition in hospitalized patients [15].
- In a six-month placebo-controlled clinical trial of female athletes supplemented with bovine colostrum, those in the colostrum group experienced decreases in thiobarbituric acid reactive substances (TBARS), a marker of lipid peroxidation, along with increases in superoxide dismutase (SOD), an antioxidant enzyme, transferrin, a protein that transports iron through the blood and lactoferrin, an anti-bacterial iron regulating protein. The authors state that “bovine colostrum supplementation is beneficial in the reduction of the harmful effects produced by free radicals (ROS), oxidative stress, and inflammation. In consequence, alleviation of the inflammatory response by bovine colostrum supplementation may also cause positive action on iron homeostasis in female athletes” [16]

Tissue regeneration and wound healing
- A randomized, controlled clinical trial of 94 patients recovering from a surgically-repaired femur fracture found that supplementation with colostrum for 21 days led to a significant, positive increase in weight gain, appetite, serum albumin, hemoglobin, and lymphocytes when compared to whey protein. Additionally, patients given colostrum reported lower disability index scores compared to the whey group [17].
- A comparative study of 200 patients on the efficacy and safety of biological wound dressings (colostrum) versus conventional dressings in deep wounds found that those in the colostrum group experienced shorter healing times, less pain, and fewer dressings when compared to the conventional group [18].
“There are seven different growth promoters identified in colostrum involved in growth and repair of body cells. Three of the seven factors identified are involved in the healing of wounds. Nucleotides, EgF (Epidermal growth factor), TgF (Transforming growth factors), FgF (Fibroblast growth factors) and IgF-I (Insulin-like growth factor) stimulate skin growth, cellular growth, and repair by direct action on DNA and RNA.”
A Comparative Study of Colostrum Dressing Versus Conventional Dressing in Deep Wounds, Kshirsagar et al., 2015
Better performance & faster recovery
- In a randomized, double-blind, placebo-controlled, parallel-design study of 51 men, 8 weeks of supplementation with colostrum versus whey protein led to significant increases in peak vertical jump power and peak cycle power, along with non-significant increases in alactic anaerobic work capacity and one-rep max capacity [19].
- A double-blind, randomized, placebo-controlled study of both male and female field hockey players found that 8 weeks of colostrum supplementation versus placebo (whey protein) led to significant improvements in 5 x 10-meter sprint test performance, along with non-significant improvements in vertical jump performance [20].
- An 8-week study of 42 cyclists randomized to three groups—low dose colostrum and whey, high dose colostrum, or moderate dose whey (placebo)—found that participants given either low or high doses of colostrum were significantly faster during a work-based time trial following a 2-hour cycle at 65% VO2max compared to the participants given placebo [21].
- A randomized, double-blind, parallel design, placebo-controlled 8-week study of 30 active men found that when colostrum supplementation was compared to placebo (whey protein powder), those in the colostrum group’s second exercise test were improved by 5.2% by week 8, likely due to the enhancement of recovery. This improvement was measured by calculating participants’ effective peak running speed during two incremental treadmill sessions separated by 20 minutes of passive recovery, conducted three times over the eight-week period [22].
“Colostrum…increases appetite, hemoglobin, serum albumin level, and the number of blood lymphocytes…it can also accelerate weight gain [muscle] and physical performance after surgery.”

Frequently Asked Questions
What is the serving size for our New Zealand Grass-Fed Colostrum?
The standard serving for our colostrum is 1 teaspoon (2g). This can be somewhat confusing because a teaspoon is a volume measurement (5mL), while 2g refers to the powder’s weight.
New Zealand colostrum powder has a lower density due to its fine, light texture, meaning 1 teaspoon weighs approximately 2g.
Is dosing different for babies or children?
- Between 2-5 years of age: 1/4 teaspoon (0.5 g) daily
- Over 5 years of age: 1/2 teaspoon (1 g) daily
- Infants can be given colostrum powder with their formula.
What if I’m pregnant or nursing?
Can I take colostrum with other prescription medications?
Please seek the advice of your doctor if you’re taking prescription medication.
For example, it is not recommended to take bovine colostrum if you are on immunosuppressive medication. Discontinue use if you experience adverse reactions and consult your doctor.
What about dosing for athletes?
Can I give colostrum to my pets?
Yes! It’s great for animals as well.
Sprinkle New Zealand Grass-Fed Colostrum directly in their dish.
- Small dogs and cats: 1 tsp daily
- Medium to large dogs: 1 tsp twice daily (morning and night)
- Horses: 2 tsp twice daily (morning and night)
How is your colostrum collected? Is it harmful to baby cows?
Is your colostrum organic? I don’t see that label on the bottle.
Why is colostrum from New Zealand so special? Other brands advertise colostrum collected in the United States…wouldn’t that be a better option?
- Year-round pasture grazing: Thanks to New Zealand's temperate climate, cows graze on grass year-round, unlike in the US, where seasonal feed supplements are often required.
- Strict farming practices: New Zealand prohibits the use of synthetic growth hormones like rBST, ensuring natural and clean dairy production.
- High animal welfare standards: New Zealand’s regulations emphasize sustainable and humane farming practices.
Additionally, our colostrum is collected, chilled, and transported immediately to the processing plant, preserving the delicate proteins and nutrients without freezing.
Unlike other colostrum products that may be frozen and stored for long periods, our low-temperature processing ensures that the biological activity of the proteins remains intact, allowing for maximum potency and effectiveness in every dose.
Moreover, we are aware of several large companies claiming that their US-sourced colostrum is “grass-fed” when in fact it is actually sourced from conventionally raised cows that are simply supplemented with some grass, rather than truly pasture-raised. If you’re in doubt about the farming practices of the company you’re sourcing from, please ask for 3rd party proof that the animals truly are pasture-raised.
Are there alternative ways to use colostrum rather than eating it?
- Cuts/skin irritation: Sprinkle some of the powder on the affected area (please refer to the study above that used colostrum in wound dressings).
- Oral issues (e.g., sensitive gums or teeth): Apply some powder along the line of your affected gum or teeth and let it dissolve.
- Sore or inflamed throat: You can gargle colostrum with lukewarm water.
