My gut has been noticeably better since starting this. Less bloating, more comfortable digestion and I feel like I'm absorbing nutrients better overall. The 2300mg dose feels like a proper amount.

Our Colostrum formula is engineered to support immune function, gut integrity, and recovery processes at a foundational level.
Designed to support overall physiological resilience, it helps maintain immune strength, digestive health, and performance recovery as part of daily wellness.
At its core is 2300 mg of premium bovine colostrum per serving, standardised to 25% Immunoglobulin G (IgG) — bioactive immune proteins involved in supporting normal immune system function and defence processes.
This is combined with naturally occurring growth factors, peptides, and nutrients found in colostrum, supporting intestinal barrier integrity and gut environment balance, which play a key role in digestion and nutrient absorption.
The formula also supports post-exercise recovery pathways, with colostrum’s bioactive compounds contributing to the maintenance of physical performance and recovery adaptation during periods of training stress.
Our Colostrum formula is designed for daily use to support immune health, gut function, and recovery from physical activity.
The Science
Evidence-Based Formulation
Every ingredient in Colostrum is selected based on peer-reviewed clinical research — standardised bovine colostrum at a therapeutic dose, supporting gut integrity and immune resilience.

Bovine Colostrum and Gut Permeability and Intestinal Barrier Function
“A randomised, double-blind, placebo-controlled study found that bovine colostrum supplementation significantly reduced gut permeability (intestinal leak) caused by NSAID use in healthy athletes, measured by the lactulose:rhamnose ratio. The protective effect was attributed to ...”

Bovine Colostrum and Gastrointestinal Health and Immune Support
“A clinical review found that bovine colostrum supplementation significantly improved markers of gastrointestinal health and systemic immune function, with reductions in gut permeability, improvements in mucosal IgA levels, and reduced incidence of upper respiratory tract infec...”

Immunoglobulins in Bovine Colostrum and Gut Pathogen Binding
“Research on immunoglobulin G (IgG) fractions from bovine colostrum found that these antibodies can bind to and neutralise a wide range of gastrointestinal pathogens, including Clostridium difficile, rotavirus, and enterotoxigenic E. coli, providing passive immune protection in...”

Bovine Colostrum and Immune System Modulation
“A controlled clinical investigation confirmed that bovine colostrum supplementation modulates immune function by increasing salivary and intestinal secretory IgA levels, supporting mucosal immune defences. Colostrum also demonstrated immunomodulatory effects on natural killer ...”

Bovine Colostrum and Strength and Lean Mass in Older Adults During Resistance Training
“An 8-week randomised controlled trial of 60 g/day bovine colostrum versus whey protein in older adults undergoing resistance training found that the colostrum group achieved significantly greater lower body strength gains (leg press +24 kg vs +8 kg for whey; p<0.01) and a grea...”

Bovine Colostrum and IGF-1 Levels and Anabolic Recovery in Strength Athletes
“A randomised controlled trial of bovine colostrum supplementation in strength athletes found significant increases in serum IGF-1 levels compared to placebo, supporting anabolic recovery, muscle protein synthesis, and lean tissue maintenance after intense training. Colostrum-s...”

Benefits
- Supports intestinal barrier integrity and reduces gut permeability
- Strengthens immune defence through IgG and bioactive proteins
- Supports recovery from physical training and digestive stress
- Helps maintain healthy gut microbial balance
- Promotes overall gastrointestinal resilience and comfort
Why our Colostrum
Most colostrum supplements have no guaranteed IgG content — the same product from the same brand can vary significantly in immunoglobulin and growth factor concentration between batches, with no standardisation for the consumer to rely on. Ours is standardised to 25% IgG, delivering 575mg of active immunoglobulins per serving alongside bioactive IGF-1 and TGF-β growth factors. Heat-sensitive proteins like IgG begin to denature at relatively low temperatures, which is why we recommend mixing cold — it's not a preference, it's a formulation decision.

How to Take
Mix one level scoop with 150–200ml of cold water or your preferred cold drink. Consume within 10 minutes of mixing.
Colostrum proteins and immunoglobulins are heat-sensitive — always use cold or room-temperature liquid, never hot. Taking first thing in the morning on an empty stomach maximises absorption through the gut lining before other food competes. Benefits for immune function, gut integrity and recovery typically build over 4–8 weeks of consistent daily use.

Verified Customer Reviews
What our customers say.
Started colostrum for immune support and it's been brilliant. Got through winter without picking up anything. The properly standardised IgG content makes this stand out from cheaper alternatives.
The recovery benefits surprised me most. I train five days a week and I'm bouncing back faster between sessions since adding this. Really well-formulated product — nothing like it on the market.
My gut health has genuinely transformed since starting this. I train hard five days a week and my recovery is noticeably faster — I believe a lot of that comes down to the gut lining support.
The IgG content is what sold me on this product — most colostrum supplements are vague about standardisation. Knowing exactly what you're getting at 30% IgG makes a big difference.
Had recurring mild gut issues for years. Two months on this and the difference is remarkable. Less discomfort, more consistent digestion and a noticeable improvement in overall energy.
I take this for immune support primarily and I've genuinely had fewer bugs this winter. Hard to attribute definitively but I'm now on my third bottle and not planning to stop.
The recovery benefits are real. I do endurance sports and since adding colostrum my gut tolerance during and after long training sessions has improved significantly.
Really well formulated — 2300mg equivalent dose and properly standardised. This is a serious colostrum product, not the underdosed alternatives you see elsewhere.
My bloating has almost completely resolved after six weeks on this. I'd been struggling with gut permeability issues for a long time and nothing else made this much of a difference.
