Immune Defence Proteins (IDP)

The bodily manifestations of ageing are a result of what has already happened at the cellular level in all of our organs. The changes in our cells have been studied and categorised as the hallmarks of ageing.

Ingredient Summary

IDP supplement product

Bioactive whey protein complex from pasture-fed milk provides selective antimicrobial activity, targeting harmful pathogens while sparing beneficial probiotics. IDP® supports gut health and the immune system with anti-inflammatory properties and a blend of lactoferrin, lactoperoxidase, immunoglobulins, and other bioactive proteins, offering natural protection against free radicals, inflammation, and infection.

Ingredient Details
Origin New Zealand pasture fed cows
Benefits Antioxidants which prevent oxidative stress on all organs
Actives: Over 50 milk bioactives including lactoferrin, lactoperoxidase and immunoglobulins

The Science


What is IDP® and how does it work?

IDP® - is 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.

IDP® anti-inflammatory properties support tight gut junctions which are important for maintaining good digestive health and supporting our immune system. If tight junctions loosen this can lead to accelerated organ ageing and many deleterious downstream effects.

IDP® combines lactoferrin, lactoperoxidase and immunoglobulins together with 50+ minor bioactive proteins - this novel whey protein fraction delivers a powerful synergy that supports the immune system by providing natural protection from free radicals, inflammation and infection.

It is a safe and effective natural option for supporting health and wellness. The powerful synergy has far greater potency than its key isolates (lactoferrin, lactoperoxidase and immunoglobulins). These work together to support the bodies microbiome and provide effective immune support – based on powerful anti-microbial, anti-viral and anti-inflammatory properties.


IDP® anti-microbial activity

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.
