The Active Ingredient Is: Colostrum (Bovine Colostrum)

Colostrum is the first form of milk produced after calving and is rich in immune factors. This product uses bovine colostrum standardised to a minimum IgG content to support immune preparation and overall wellbeing.

The formulation also includes zinc, a recognised mineral for immune support, alongside a prebiotic to assist gut comfort and vitality.

What Does Colostrum Do?

Colostrum contains immunoglobulins that contribute to immune defence and may support gut barrier integrity. This combination, together with zinc, aligns with evidence that immune function and infection resistance can be supported by these nutrients.

Zinc contributes to normal immune system function and helps protect cells from oxidative stress, which complements the role of colostrum in maintaining resilience.
