Gut Health / Immunity
Nature's first food. Grass-fed bovine colostrum with >25% IgG antibodies for gut lining repair, immune transfer, and growth factor support.
Why It Works
Colostrum is nature's mechanism for transferring immune intelligence from mother to newborn. It's loaded with immunoglobulin G (IgG) antibodies that survive digestion and directly support the immune system in the gut — where 70% of your immune function resides. Our colostrum is standardised to >25% IgG, well above the industry average.
Growth factors in colostrum — including IGF-1, TGF-β, and EGF — directly support the repair and regeneration of intestinal epithelial cells. Colostrum has been shown to strengthen tight junctions between gut cells, addressing the root cause of intestinal permeability ("leaky gut") rather than just managing symptoms.
Intense exercise increases intestinal permeability and temporarily suppresses immune function. Colostrum has been studied in athletes and shown to reduce exercise-induced gut damage, support post-workout immune recovery, and decrease upper respiratory infections during heavy training blocks. It's why elite athletes are increasingly adding colostrum to their protocols.
Colostrum contains over 90 bioactive compounds including lactoferrin (antimicrobial, iron transport), proline-rich polypeptides (immune regulation), and a spectrum of growth factors that support tissue repair throughout the body — not just the gut. It's the most complex whole-food supplement available.
Formula
Each batch is independently tested to verify IgG content (>25%), screen for antibiotics, hormones, heavy metals, and microbial contamination. Grass-fed sourcing is verified. Certificate of Analysis available on request.
Protocol
Dose: 1 scoop (2g) daily
Timing: First thing in the morning on an empty stomach, 20 minutes before food. This maximises contact with the gut lining.
Research
Bovine colostrum is the pre-milk fluid produced by cows in the first 24–48 hours after giving birth. It's fundamentally different from regular milk — it contains 100x more immunoglobulins, concentrated growth factors, and a unique profile of bioactive compounds evolved specifically to establish immune function and gut integrity in newborns. Bovine colostrum is remarkably similar to human colostrum in composition, and the IgG antibodies it contains are bioactive in the human gut.
The gut health mechanism centres on tight junctions — the protein structures that seal the gaps between intestinal epithelial cells. When these junctions break down (due to stress, NSAIDs, alcohol, or chronic inflammation), the gut becomes permeable, allowing undigested food particles and bacterial endotoxins to enter the bloodstream. This triggers systemic inflammation. Colostrum's growth factors — particularly IGF-1, TGF-β, and EGF — directly stimulate epithelial cell proliferation and tight junction protein expression, physically repairing the gut barrier. Studies using NSAID-induced gut damage models show colostrum can prevent and reverse intestinal permeability.
The immune benefits are equally compelling. IgG antibodies in colostrum bind to pathogens, toxins, and allergens in the gut lumen, neutralising them before they can interact with the immune system. Lactoferrin provides antimicrobial activity and modulates iron availability (starving pathogenic bacteria of iron). Proline-rich polypeptides (PRPs) regulate the immune response — upregulating when needed and calming overactive immune responses. For athletes, multiple studies demonstrate that colostrum supplementation reduces exercise-induced gut permeability, decreases upper respiratory tract infection rates during heavy training, and supports faster recovery between sessions.
Quality
Sourced from grass-fed, pasture-raised cows. No feedlot animals, no routine antibiotics, no added hormones. The health of the animal directly impacts the quality of the colostrum it produces.
We use only first-milking colostrum (collected within 6 hours of calving) for maximum IgG concentration. Processed using low-heat spray drying to preserve fragile immunoglobulins and growth factors that high-heat methods destroy.
GMP-certified facility with dairy-grade hygiene standards. Every batch tested for IgG content (>25%), antibiotic residues, hormone contamination, heavy metals, and microbial limits. Full COA available.
Reviews
Dealt with gut issues for years — bloating after meals, food sensitivities getting worse over time. Four weeks on colostrum and the bloating has reduced significantly. I can eat foods that used to wreck me. The gut lining repair is real.
Training 6 days a week and I used to catch a cold every time I ramped up volume. Started colostrum two months ago and haven't been sick since, even during a heavy overreaching block. The immune support during hard training is noticeable.
The >25% IgG is what sold me — most colostrum products won't even disclose their IgG content because it's embarrassingly low. Taste is mild and creamy, mixes easy into water. Taking it with collagen peptides as a morning gut protocol.
My naturopath recommended colostrum for leaky gut. After trying two other brands with no results, this one actually worked — I think it's the IgG concentration difference. Digestion is smoother, less reactive to foods, and my seasonal allergies have improved too.
