Bovine Colostrum 500mg | 30% IgG | Immune and Gut Support | 60 Vcaps

Each vegan capsule delivers 500 mg of bovine colostrum (Bos taurus, colostrum), standardized to 30% immunoglobulin G (IgG) providing 150 mg of IgG per capsule. At the recommended dose of 3 colostrum capsules once daily, each serving provides 1,500 mg of bovine colostrum and 450 mg of IgG. Sourced from Canadian pasture raised dairy cows. Supports immune health.

What Is Bovine Colostrum?

Bovine colostrum (colostrum bovin) is the first milk produced by dairy cows (Bos taurus) in the 24–72 hours after calving, before the onset of regular milk production. It is compositionally distinct from regular cow’s milk, containing significantly higher concentrations of immunoglobulins (particularly IgG), growth factors, lactoferrin, lysozyme, and other bioactive proteins. Colostrum is the richest natural source of immunoglobulin G (IgG) the primary antibody class in bovine colostrum, comprising approximately 70–80% of its total immunoglobulin content.

Why 30% IgG Standardization?

The IgG content of raw bovine colostrum varies naturally depending on the cow, time of collection after calving, breed, and processing method. Without standardization, IgG levels in colostrum supplements can vary significantly between batches and products. Standardization to 30% IgG means every colostrum capsule contains a consistent, verified 150 mg of IgG per 500 mg capsule regardless of natural variation in the raw material. This ensures consistent potency and a quantified colostrum IgG dose with every serving.

Immune Support & Gut Health

IgG immunoglobulins are the primary bioactive marker used to assess bovine colostrum supplement quality and potency. This colostrum supplement provides 450 mg of standardized IgG per daily serving the quantified, Health Canada licensed dose for immune support. In addition to colostrum immune support, the bioactive proteins in bovine colostrum including growth factors and lactoferrin are associated with gut health benefits, particularly in supporting the integrity of the gut lining.

Canadian Pasture Raised Source

This bovine colostrum supplement is sourced from pasture-raised dairy cows (Bos taurus) in Canada, under federal and provincial regulatory oversight with defined standards for animal welfare, veterinary care, and milk quality. Formulated and manufactured entirely in Canada under Health Canada oversight.

Clinical Research

Bovine colostrum supplementation and immune function: a systematic review

Nutrition Reviews, 2011

This systematic review examined randomized controlled trials of bovine colostrum supplementation in healthy adults and athletes. The review found consistent evidence that bovine colostrum supplementation supported immune function markers, including immunoglobulin levels and immune cell activity, compared to placebo. The authors identified IgG content as the primary bioactive fraction responsible for immune related outcomes, supporting the rationale for standardization to a guaranteed IgG percentage in bovine colostrum supplements.

Bovine colostrum and gastrointestinal health: a review of clinical evidence

Journal of Nutritional Science, 2016

This review examined clinical evidence for bovine colostrum's effects on gastrointestinal mucosal integrity and gut associated immune function. The research found that bovine colostrum's immunoglobulin and lactoferrin content supported gut mucosal health markers in clinical studies. The authors concluded that bovine colostrum represents a well tolerated natural health ingredient with a documented safety profile and evidence base for gut and immune health applications.

Immunoglobulin G from bovine colostrum: bioavailability and immune effects in humans

European Journal of Clinical Nutrition, 2003

This clinical study examined the bioavailability and immune effects of IgG derived from bovine colostrum in healthy human subjects. The study found that orally administered bovine colostrum IgG was detectable in the gastrointestinal tract and was associated with measurable immune activity. The findings support the use of standardized bovine colostrum IgG as a bioavailable immune health ingredient and confirm that IgG content is the critical quality marker for bovine colostrum supplementation

Frequently Asked Questions

What is bovine colostrum and what is it used for?

Bovine colostrum is the first milk produced by dairy cows (Bos taurus) in the first 24 to 72 hours after calving. It is compositionally distinct from regular cow's milk, containing significantly higher concentrations of immunoglobulins, lactoferrin, and bioactive proteins. Bovine colostrum supplements are used to support immune health in adults. Consult a healthcare practitioner before use.

What does 30% IgG mean in a bovine colostrum supplement?

IgG (immunoglobulin G) is the primary immunoglobulin class in bovine colostrum and the key marker used to assess colostrum quality and potency. Standardized to 30% IgG means every capsule is manufactured to contain 30% IgG by weight providing 150mg of IgG per 500mg capsule, and 450mg of IgG per daily serving of 3 capsules. Non-standardized colostrum products may have variable and unverified IgG content.

Who should not take bovine colostrum?

Do not use bovine colostrum if you have a known allergy or hypersensitivity to cow's milk. Consult a healthcare practitioner before use if you are pregnant or breastfeeding, have diabetes, a history of cancer, or an immune system disorder including Crohn's disease, myasthenia gravis, multiple sclerosis, rheumatoid arthritis, systemic lupus erythematosus, or HIV/AIDS. Consult a healthcare practitioner before use if you are taking immunosuppressive medications. Keep out of reach of children.

Is bovine colostrum dairy-free or suitable for lactose intolerant individuals?

Bovine colostrum is derived from cow's milk and is not suitable for individuals with a known allergy or hypersensitivity to cow's milk. Those with lactose intolerance should consult a healthcare practitioner before use, as colostrum contains milk-derived proteins. The capsule shell is hypromellose (plant-derived) no gelatin making it suitable for vegetarians.

Does bovine colostrum support gut health?

Bovine colostrum contains immunoglobulins, lactoferrin, and bioactive proteins naturally present in the first milk of dairy cows. Consult a healthcare practitioner for advice specific to your digestive health needs and to determine whether bovine colostrum is appropriate for your individual situation.
