Colostrum is one of the most ancient natural substances known to support life. Produced by all mammals in the first few days after giving birth, it plays a critical role in the health and development of newborns.

In recent years, interest in Colostrum has extended beyond early life and into areas like nutrition, wellness, and skincare—thanks to its rich composition of proteins, antibodies, growth factors, and other biologically active components.

What is Colostrum?

Colostrum is the initial fluid produced by mammals for around 72 hours following birth. Unlike milk, it is thick, golden in colour, and contains a highly concentrated mix of immune and growth-supporting substances. In its natural role, Colostrum helps establish immunity and provides essential nutrients for growth and development.

From a scientific perspective, Colostrum contains:

• Immunoglobulins (IgG, IgA, IgM)
• Growth factors (IGF-1, TGF-β)
• Lactoferrin
• Cytokines
• Essential amino acids and vitamins

These components have been studied for their potential roles in immune support, tissue development, and cellular health.

Why Bovine Colostrum?

While all mammals produce Colostrum, bovine (cow) Colostrum is often used in supplement and skincare formulations due to its availability and nutrient density. It has been reported to contain significantly higher levels of immunoglobulins and growth factors than human Colostrum—some estimates suggest up to 200 times more in certain compounds.

Colostrum and Skin

Although traditionally consumed orally, Colostrum has also been explored in topical applications. The naturally occurring components in Colostrum—especially growth factors and proteins—are of interest for their role in:

• Supporting skin cell function
• Maintaining the skin barrier
• Promoting hydration
• Assisting with natural cell renewal

It’s important to note that while laboratory and preclinical studies provide insights into Colostrum's properties, topical use in skincare is still an emerging area of interest, and research is ongoing.

The Role of New Zealand in Colostrum Science

New Zealand has been at the forefront of Colostrum research and processing. With a well-established dairy industry and strict quality control standards, the country developed the first low-temperature drying process for Colostrum, which helps preserve its biological activity.

Colostrum used in skincare products from New Zealand is typically sourced from grass-fed cows, and collection is done under ethical and regulated practices. The surplus—after calves have had their required intake—is carefully collected for human use.

A Natural Ingredient, Minimally Processed

Colostrum used in topical products is often non-denatured and free from chemical additives. In its pure form, it contains no synthetic preservatives or fillers, making it suitable for use in formulations that prioritize natural composition.

Colostrum is a naturally produced substance known for its complex mix of immune-supporting and growth-associated compounds. While its primary role is in early life development, ongoing research continues to explore its broader applications—including in skincare. Bovine Colostrum sourced from New Zealand benefits from high production standards and innovative processing methods, which help retain its bioactive properties.

Note: Skincare products containing Colostrum are designed for topical use. While Colostrum has been widely studied, skincare products do not claim to treat or prevent any medical conditions. Always read the label and use as directed. If irritation occurs, discontinue use and consult a health professional.
