How Cowboy Works

Cowboy Colostrum delivers nature's first food - liquid gold - in its purest and most bioavailable form, rich in vital nutrients and antibodies that bolster the body's immune defenses. By preserving the natural potency of colostrum, Cowboy’s full-fat, first-milking formula is crafted exactly as nature intended.

When you take Cowboy Colostrum, its proteins, natural growth factors, and antimicrobial peptides work in harmony to enhance your immune response and reduce inflammation, while also repairing and balancing your gut lining. Packed with immunoglobulins that create a protective barrier against infections, Cowboy Colostrum synergizes with your body’s natural defenses to support recovery, immunity, and overall wellness, making it a true superpower in your cup.


Bioactive Potency

Bovine colostrum is a potent source of unique bioactive compounds not commonly found in nutrition. Cowboy Colostrum features significantly higher bioactivity due to our first-milking philosophy. Its rich profile includes immunoglobulins, cytokines, lactoferrin, vitamins, minerals and more, contributing to benefits like gut fortification, immune enhancement, energy balance, and pathogen protection. Notably, oligosaccharides offer prebiotic effects and inhibit harmful bacteria; meanwhile, high levels of glycosylated proteins and whey proteins enhance gut microbiome health and support immune modulation and tissue repair.

“Bovine colostrum-derived lactoferrin has antimicrobial activity by inhibiting the growth of disease-causing protozoa, yeasts, bacteria, and viruses, and lactoferrin may prevent the attachment of pathogens to epithelial cells and help maintain intestinal permeability and stability…”

Colostrum's Key Players

Colostrum is a natural source of various beneficial components, including vitamins, minerals, proteins, and enzymes.*

Let's take a closer look:

Lactoferrin: 

An important protein that promotes the health of the intestinal lining and contributes to immune system functioning.*

Cytokines: 

These act as messengers, facilitating communication among immune system cells to ensure their coordinated response.*

Immunoglobulins (IgG, IgA, IgD, IgE, IgM): 

These antibodies play a crucial role in modulating the body's immune response.*

Proline-Rich Polypeptides (PRPs): 

Amino acids that help regulate the immune system and support the production of white blood cells.*

Growth Factors (IGF-I, IGF-II, EGF): 

Essential hormones that contribute to the growth and maintenance of tissues in the gastrointestinal tract. Colostrum houses vital growth factors, including TGF-a, TGF-b, IGF-1, and IGF-2. Colostral IGF-1 enhances lean muscle and, when integrated into exercise, orchestrates a metabolic shift from glycolysis to lipid metabolism, optimizing fat catabolism and imparting a nuanced biochemical impact to physical activity.*


Your golden years are ahead.

First milking method to maintain bioactive potency

Once baby calves finish feeding, we collect 4-6 hour first milking colostrum from grass-fed cows, then turn it from liquid gold to powdered gold. This first milking approach gives our colostrum the highest level of bioactive potency.

Collected with intention

Our colostrum comes from U.S. dairy farms where the needs of the baby calves always come first. Cows produce more milk than their spawn can consume, so we up-cycle their surplus, ensuring no gold goes to waste.

Handled with care

We leave our colostrum fully intact - full-fat, unstripped, undiluted. Nature created a perfect formula with no need to tweak it in a lab. Our colostrum is made in smaller and fresher batches, filled with fat and protein for ultimate nutrient density.*
