What is the purpose of taking a colostrum (first milk) supplement?

From the Guidelines

Colostrum supplements are taken to support immune function, promote gut health, and provide essential nutrients, as evidenced by the high concentration of immunoglobulins, such as secretory IgA, and other bioactive compounds found in human milk, as reported in a 2023 study published in Critical Reviews in Food Science and Nutrition 1. The primary purpose of taking a colostrum supplement is to utilize the bioactive components present in the first milk produced by mammals after giving birth. These components include:

• Hormones, such as glucocorticoids, melatonin, leptin, and insulin, which play a crucial role in regulating various physiological processes, including stress response, energy regulation, and growth 1
• Immune factors, such as secretory IgA, lactoferrin, and other immunoglobulins, which provide protection against pathogens and support the development of the infant's immune system 1
• Maternal cells, including immune cells, such as leukocytes, and non-immune cells, such as lactocytes and stem cells, which contribute to the protection of the infant and the mammary gland against infections 1
• Nutrients, including fats, proteins, and sugars, which are essential for the growth and development of the infant 1 Taking colostrum supplements may help strengthen the immune system, promote digestive health, and support the growth of beneficial gut bacteria. The typical dosage of colostrum supplements ranges from 500mg to 3g daily, taken with water on an empty stomach. However, it is essential to note that the quality and efficacy of colostrum supplements may vary depending on the source and manufacturing process. Some of the key benefits of colostrum supplements include:
• Supporting immune function and reducing the risk of infections
• Promoting gut health and reducing symptoms of leaky gut syndrome
• Providing essential nutrients and supporting the growth and development of infants
• Possibly enhancing recovery and performance in athletes However, it is crucial to consult with a healthcare provider before taking colostrum supplements, especially for individuals with dairy allergies or those who are pregnant or nursing. Additionally, the supplement should be sourced from a reputable manufacturer to ensure quality and efficacy.

From the Research

Purpose of Taking a Colostrum Supplement

The purpose of taking a colostrum supplement can be understood through its potential benefits, which include:

• Improving gut function and health in humans, especially when immune and gut functions are immature in early life 2
• Reducing clinical complications related to preterm birth, infections, and gut disorders 2
• Enhancing immune function and improving performance in athletes 3, 4
• Maintaining gastrointestinal integrity by decreasing GI permeability during exercise in the heat 3
• Treating gastrointestinal disorders, such as inflammatory bowel disease and chemotherapy-induced mucositis 5

Key Components of Colostrum

Colostrum is a rich natural source of:

• Macro- and micro-nutrients
• Immunoglobulins
• Peptides with anti-microbial, immune modulatory, and/or growth-factor activity 6
• Growth factors, such as IGF-I, which may improve exercise performance 4
• Immunoglobulins, cytokines, lactoferrin, and hormones, which may improve the functioning of the digestive, immune, and neuroendocrine systems 4

Potential Benefits for Different Populations

Colostrum supplementation may be beneficial for:

• Infants and children, especially those with immature immune and gut functions 2
• Athletes, particularly during periods of high intensity training 3, 4
• Individuals with gastrointestinal disorders, such as inflammatory bowel disease and chemotherapy-induced mucositis 5
