Immune Defense Proteins (IDP®)

What is IDP?

A bioactive whey protein complex extracted from pasture fed milk. It provides effective selective antimicrobial activity to support the body’s microbiome.

This selective antimicrobial activity supports our microbiome by suppressing harmful pathogens and viruses, while being relatively ineffective against important probiotic and commensal species that the body needs to maintain good health.

Lactoferrin, lactoperoxidase, immunoglobulins are some of the 50+ bioactive proteins that are found in IDP. Beyond their essential nutrient function in providing amino acids, the proteins present in IDP play an active role in supporting our immune system. Bioactive proteins have proven antioxidant, anti-inflammatory, antimicrobial and antiviral properties. Lactoferrin and lactoperoxidase in particular play an important role in our innate immune defence system. They boost the body’s natural protection against pathogens and viruses. Bioactive proteins are naturally present in biological fluids including saliva and tears. Made from pasture fed New Zealand milk which has significant benefits for the milk nutritional profile and animal welfare. Every batch is tested to confirm the presence of key target bioactive proteins and bioactive functionality.

How IDP works

Cellular Repair

IDP plays a critical role in promoting cellular repair by enhancing the body’s mucosal immunity. Its unique ability to support tissue healing in epithelial linings—such as the gut, lungs, and skin—accelerates recovery from damage and helps prevent infection.

Immune Support

IDP strengthens the immune system by bolstering mucosal immunity, the body’s first line of defense against pathogens. It also increases the activity of antimicrobial peptides, improving the body's natural ability to fend off harmful microbes and viruses.

Gut Health

IDP protects the gut lining, reducing inflammation in the intestinal tract and promoting better nutrient absorption. By supporting gut barrier integrity, IDP helps reduce the risk of leaky gut and related immune dysfunctions, promoting overall gut health.
