What is the recommended dosage for Bovine Colostrum?

General: 10-20 g/day; Travelers Diarrhea: Hyperimmune colostrum: 400-3,600 mg/day (anti-ETEC formulation); Exercise Gut Protection: 20 g/day starting 14 days before intense exercise; Intestinal Permeability: 20-60 g/day for gut barrier support

What are the side effects of Bovine Colostrum?

Potential side effects include: Mild GI discomfort (bloating, nausea) during initial use, Not suitable for individuals with cow's milk protein allergy, Lactose content may affect lactose-intolerant individuals, Potential concern about growth factor (IGF-1) content in cancer survivors (theoretical).

What is bovine colostrum and how does it work for gut health?

Bovine colostrum is the first milk produced by cows after giving birth, rich in immunoglobulins (IgG), lactoferrin, growth factors, and proline-rich polypeptides. Research suggests it may help strengthen the intestinal barrier, reduce gut permeability (often called "leaky gut"), and support mucosal immune function. Its growth factors, particularly IGF-1, may help repair and regenerate intestinal tissue.

What is the recommended dosage of bovine colostrum?

Clinical studies have used bovine colostrum at dosages ranging from 500 mg to 20 g per day, with most trials using 3-10 g daily. For gut permeability support, studies have typically used 10-20 g per day. It is usually taken on an empty stomach or 30 minutes before meals for optimal absorption of immunoglobulins.

Are there side effects or interactions with bovine colostrum?

Bovine colostrum is generally safe for most adults, though individuals with dairy allergies or lactose intolerance should exercise caution. Mild gastrointestinal symptoms like nausea or bloating may occur initially. People with hormone-sensitive conditions should be aware that colostrum contains small amounts of growth factors, and should consult their healthcare provider.

About

Bovine colostrum is the first milk produced by cows after calving, rich in immunoglobulins (IgG, IgA), lactoferrin, and growth factors (IGF-1, TGF-beta). Research suggests it may help reduce intestinal permeability, particularly during NSAID use and intense exercise, by protecting mucosal integrity. Hyperimmune colostrum (containing anti-ETEC antibodies) may also provide passive immunity against enteric pathogens associated with traveler's diarrhea.

How It Works

Contains immunoglobulins (IgG, IgA) providing passive immunity against enteric pathogens; lactoferrin exerts antimicrobial and anti-inflammatory activity; growth factors (IGF-1, TGF-beta) promote intestinal epithelial repair and tight junction integrity; reduces NSAID-induced intestinal permeability by up to 80% in exercise models.
