Ingredient Profile: IDP®

IDP® — Immune Defense Proteins — is the New Zealand bioactive whey protein complex at the heart of Re:juvenate Pro. Here is a closer look at what it is, where it comes from, and the role it plays in supporting everyday health.

What is IDP®?

IDP® is a bioactive whey protein complex extracted from pasture-fed New Zealand milk. It brings together lactoferrin, lactoperoxidase and immunoglobulins alongside 50 or more minor bioactive proteins — a novel whey protein fraction that works in synergy to support the immune system and the body’s natural defences.

Beyond their role as a source of amino acids, these proteins are naturally active in the body. Bioactive proteins such as lactoferrin and lactoperoxidase are part of our innate immune system and occur naturally in biological fluids like saliva and tears. Combined with antioxidant activity that helps neutralise free radicals, the whole fraction works with a synergy greater than its individual isolates alone — making IDP® a natural option for supporting everyday health and wellbeing.

Supporting a balanced microbiome

IDP® has a selective action that helps support the balance of the body’s microbiome. It helps keep less favourable microbes in check while largely sparing the beneficial probiotic and commensal species your body relies on to stay well — helping maintain the microbial balance that underpins good health.

Supporting your natural immune defences

The bioactive proteins in IDP® help support the body’s natural first-line defences. Rather than acting like a medicine, IDP® works alongside your own immune system — part of why it sits at the centre of a formulation designed to support immune resilience as we age.

Antioxidant and inflammatory balance

IDP® has antioxidant and anti-inflammatory properties that help support the body’s healthy inflammatory balance. A healthy inflammatory response is a normal and important part of how the body maintains itself, and antioxidant activity helps protect cells from the everyday effects of free radicals.

Digestive health and the gut barrier

The lining of the gut is held together by tight junctions — the seals between cells that keep the gut barrier working as it should. IDP®’s properties help support these tight junctions, and maintaining them is an important part of supporting healthy digestion and, through the gut, a resilient immune system.

Made and tested in New Zealand

IDP® is made from pasture-fed New Zealand milk, which benefits both the nutritional profile of the milk and animal welfare. Every batch is tested by Quantec to confirm the presence and functionality of its key bioactive proteins, and IDP® meets the food-safety, quality and traceability standards required for New Zealand and export markets.
