OYAH INGREDIENT LIBRARY

Bovine colostrum

Bovine colostrum contains proteins, immunoglobulins and other bioactive components. Human evidence focuses mainly on intestinal permeability and exercise settings, with large differences between products and protocols.

Evidence signalPromising but specialized and product-dependent
Research focusIntestinal permeability, exercise stress and immunity
Key qualifierProcessing, IgG specification, amount and population

What it is

Colostrum is the first milk produced after birth. Bovine colostrum supplements are derived from cows and may be standardized by immunoglobulin G content. An IgG percentage describes composition; it does not prove a clinical outcome.

What human research suggests

A 2024 meta-analysis reported lower measures of intestinal permeability across randomized trials, but studies used different products, amounts, durations and populations. Several involved athletes exposed to intense exercise or heat. Those results cannot automatically predict digestive symptoms or everyday benefits in the general population.

SAFETY & CONTEXT

What to consider before use.

Colostrum is milk-derived. Do not use it if you have a milk-protein allergy. Lactose content and tolerability vary by product. Mild gastrointestinal symptoms can occur. Evidence during pregnancy and breastfeeding is limited. People with complex medical conditions or who use immunosuppressive therapy should ask a healthcare professional before use.

This guide is educational and is not medical advice. Speak with a qualified healthcare professional about pregnancy, breastfeeding, medical conditions, medicines, surgery or persistent symptoms.
