💊 What it does
Bovine colostrum is the first milk produced by cows after calving, containing high concentrations of immunoglobulins (IgG, IgA, IgM), lactoferrin, growth factors (IGF-1, EGF), and proline-rich polypeptides. Clinical evidence supports benefits for gut health and intestinal permeability (leaky gut), immune function, respiratory infection prevention, and sports performance (muscle recovery and body composition). It is one of the most immunologically active natural supplements.
👤 Who needs it
Athletes with gut permeability issues or frequent respiratory infections. People with intestinal permeability (leaky gut) or inflammatory bowel conditions. Those recovering from illness. People seeking immune support with a strong evidence base. Note: not suitable for vegans.
🥦 Food sources first
Colostrum is only available as a supplement — it cannot be obtained from food outside of the specific first-milking period after birth.
🗓 When to supplement
For gut health and intestinal permeability. For immune support and respiratory infection prevention. For sports recovery. Not for vegans.
🏷 Best form to look for
Bovine colostrum standardised to immunoglobulin content (minimum 25% IgG). First-milking colostrum from grass-fed cows is considered superior quality.
⏰ When to take it
On an empty stomach for gut health applications. With meals for immune support.
