The Active Ingredient Is: Bovine Colostrum

Bovine colostrum is the first milk produced after birth and contains nutrients and bioactive components that support early immune and growth processes. This formulation focuses on the milk-derived colostrum as the primary ingredient, sourced from cows raised without hormones and processed to minimise unwanted proteins while retaining its bioactive properties.

This form is sourced as a liquid colostrum supplement from bovine milk, incorporating a natural protein matrix that can contribute to immune and tissue support in line with product intentions.

What Does Bovine Colostrum Do?

Bovine colostrum is associated with immune system support and tissue growth factors that may aid in normal physiological functions. NHS and EFSA-aligned perspectives recognise colostrum’s role in these areas as part of a balanced diet and immune health framework.

Within this product, the focus is on the blend of colostrum’s nutrients and growth factors that contribute to general tissue development and immune support as part of a healthy lifestyle.
