Product Description

Dr. Banks Leaky Immune Protect is a bovine colostrum immune balancing spray containing Proline-Rich Polypeptides (PRPs), which help to modulate normal immune responses.


  • Proline-Rich Polypeptides (PRPs) from Fresh Colostrum
  • Supports the Immune System*
  • Supports Healthy Cognitive Function*
  • Promotes Cytokine Production / Balancing*
  • Supports the Body's Healthy Response to Allergens*



PRPs are information-carrying proteins (peptides) with amazing adaptability. In times of immunological challenge, they enhance immune activity by promoting the production of cytokines.* Conversely, when the immune system unnecessarily reacts to environmental factors through cytokine production, PRPs send signals via specific cell receptor sites to decrease the production of cytokines.*


PRPs help regulate the thymus gland (the body’s central command for the immune system), stimulating an underactive immune system or down regulating an overactive immune system.* They inhibit the overproduction of lymphocytes and T-cells and may help reduce minor symptoms related to allergies, swelling and tenderness.*
