1. Boosts Immune System: The product contains 20% Immulox, which is known to strengthen the body's immune system and increase its ability to fight off infections and diseases.
2. Promotes Gut Health: ColostrumPRO is rich in probiotics and other beneficial nutrients that can help improve digestive health and promote the growth of good bacteria in the gut. This can lead to better digestion and absorption of nutrients, as well as a reduced risk of digestive issues.

The Active Ingredient Is: Bovine Colostrum

Bovine colostrum is the first milk produced after calving, rich in bioactive nutrients that help support normal immune and gut function. This product is standardised to include Immulox as a fraction enriched in immune-modulating components.

Form and source: sourced from the milk of cows in the early postpartum period and processed to preserve bioactives such as immunoglobulins, proline-rich polypeptides and growth factors.

What Does Bovine Colostrum Do?

Bovine colostrum helps support normal immune defences and helps maintain the integrity of the gut lining, in line with EFSA-supported nutrient functions. Lactoferrin and immunoglobulins contribute to gut and immune health pathways as described in research contexts.

Dr. Playford from the University of Adelaide found that colostrum components can modulate immune responses and support gut barrier function in healthy adults, aligning with the product's bioactive profile.
