Estimated Reading Time: 10 minutes

Bovine colostrum is the nutrient-rich milky fluid produced by cows for the first few days after they give birth. It contains high levels of nutrients and antibodies that help fight infections and support a young one’s growth.

Also known as liquid gold, miracle milk, and nature’s first food, colostrum is thicker than regular milk and is yellow in color. Though colostrum supports newborns’ growth, development, and immune systems, recently, a number of adults have turned to bovine colostrum supplements to support their overall health. Colostrum is the latest supplement trend, causing a buzz across social media platforms. This article reviews the benefits, nutrition, uses, and potential side effects of bovine colostrum supplements.

What is Bovine Colostrum?

Colostrum is the first milk produced by mammals, including humans, shortly after giving birth. For humans, it’s produced within the first 0-72 hours post-birth, while cows produce it within the first 0-6 hours.

This rich, thick fluid is loaded with essential nutrients, antibodies, growth factors, and antimicrobial peptides, all crucial for newborns' survival and development. Since newborns have immature immune systems, the high concentration of antibodies in the colostrum plays a vital role in helping fight infections and supporting early growth. This is the very reason they say that a mother’s milk is necessary for newborns.

Bovine colostrum, or cow's first milk, shares similar properties but is particularly potent. Because of its impressive health benefits, bovine colostrum has found a place in human health supplements. It’s helpful in supporting immune function, gut health, and muscle recovery, making it a popular natural supplement for boosting overall health and vitality.

A. Insulin-Like Growth Factors (IGF-I and IGF-II): Promote cell and muscle growth and repair.

B. Epidermal Growth Factor (EGF): Supports tissue repair, especially in the gut.

C. Transforming Growth Factors (TGF-α and TGF-β): Help repair gut and immune function. TGF-α helps with gut growth, while TGF-β is involved in wound healing and maintaining gut integrity.

D. Platelet-Derived Growth Factor (PDGF): Promotes the healing of injuries, especially ulcers, by stimulating cell growth.

E. Vascular Endothelial Growth Factor (VEGF): These growth factors help form new blood vessels and may support the healing of damaged tissues, such as ulcers.

F. Milk Fat Globule-Epidermal Growth Factor (MFG-E8): Supports immune function and tissue repair by removing damaged cells and promoting new blood vessel growth.

4. Fatty Acids

Bovine colostrum contains healthy fats that provide energy and support cell structure. It has a higher concentration of short-chain and medium-chain fatty acids than regular milk. The fat in the colostrum is not only a source of energy but also contains bioactive components that support immune function, brain development, and overall health. The fatty acid composition of colostrum is approximately:

65–75% saturated fat
24–28% monounsaturated fat
4–5% polyunsaturated fat

5. Hormones

Bovine colostrum contains various hormones that may influence development, especially in neonates. These hormones can pass from the gut into the bloodstream and can impact the growth and development of neonates. These hormones include:

Prolactin
Oxytocin
Thyroid hormones
Oestrogen
Progesterone
Growth hormone
Leptin

6. Antimicrobial Factors

Colostrum contains many bioactive components, including antimicrobial factors that support immune function, protect against harmful pathogens, and promote gut health by supporting a balanced microbiome. These factors include:

Immunoglobulins (IgG): The main immunoglobulin is IgG, which provides passive immunity to the calf and helps fight pathogens by binding to antigens and interacting with immune cells like phagocytes and T cells.
Other Antimicrobials: Colostrum also contains bioactive oligosaccharides, lactoperoxidase, lysozyme, and lactoferrin. These help inhibit the growth of harmful bacteria, such as E. coli, Salmonella, and others, by disrupting bacterial metabolism, binding to pathogens, and boosting the immune response.

7. Cytokines and Immune Regulators

Bovine colostrum has immune cells like B and T lymphocytes, macrophages, and neutrophils, which help fight infections. It also includes microRNA and Colostrinin (PRPs), which help regulate immune responses, reduce inflammation, and prevent excessive immune reactions.

8. Carbohydrates

Colostrum contains different types of sugar, including lactose, oligosaccharides, and glycoproteins. Lactose is the natural sugar found in milk, and it provides the body with an energy source. Some of these sugars, like 3′-sialyl lactose (3′SL) and 6′-sialyl lactose (6′SL), help good bacteria like Bifidobacteria grow. Colostrum also has a protein called glycomacropeptide (GMP), which allows useful bacteria to grow.

Benefits of Bovine Colostrum

Due to its rich nutritional profile, bovine colostrum is gaining attention for its potential health benefits, including enhanced immune function, gut health support, and overall well-being. Check below for the list of health benefits of bovine colostrum:

1. Gastrointestinal Health or Supports Gut Health

Bovine colostrum supplements play a significant role in promoting gut health. Growth factors and antibodies present in the colostrum can help maintain the integrity of the intestinal lining, thereby helping in reducing intestinal permeability or leaky gut.

Studies suggest that colostrum aids in healing the gut by reducing inflammation and promoting the regeneration of the gut lining. Additionally, bovine colostrum acts as a prebiotic and fosters the growth of beneficial gut bacteria, which is crucial for healthy digestion and gut health.

2. Supports Immune Function

Bovine colostrum is rich in bioactive compounds such as antibodies (immunoglobulins), lactoferrin, and growth factors. These components help strengthen the immune system. These powerful nutrients work by modulating the activity of various key immune cells, including lymphocytes, macrophages, and dendritic cells, which help fight infections.

Additionally, bovine colostrum may also increase regulatory cytokines like interleukin-10, a substance that helps balance immune responses and prevent excessive inflammation. Some research suggests that bovine colostrum supplements help prevent infections, especially in preterm babies or people with weak immune systems.

3. Supports Respiratory Health

Research suggests that bovine colostrum supports respiratory health. It does so by enhancing immune defense, reducing inflammation, and strengthening the respiratory barrier. Immunoglobulins (IgG, IgA, IgM) and lactoferrin present in the colostrum help neutralize pathogens and prevent infections. Cytokines (IL-10, TGF-β) and proline-rich polypeptides (PRPs) regulate inflammation and protect lung tissues from excessive immune responses.

Additionally, the epidermal growth factor in colostrum aids in repairing airway linings. At the same time, glycoproteins and oligosaccharides prevent harmful bacteria from sticking to respiratory surfaces. Secretory IgA (sIgA) further strengthens immunity defense in the airways, reducing the severity and frequency of colds and upper respiratory tract infections (URTIs).

4. May Enhance Exercise Performance

Bovine colostrum is said to improve athletic performance and speed up recovery. Colostrum is rich in immunoglobulins (IgA, IgG, IgM) and lactoferrin, which strengthen the immune system and help reduce upper respiratory tract infections, which are common in athletes who undergo intense training.

Growth factors( IGF-1, TGF-beta) in colostrum promote muscle repair and protein synthesis and reduce post-exercise inflammation and oxidative stress, leading to speedy recovery. IGF-1 also plays a role in muscle growth and bone density, helping in long-term performance. Besides, colostrum helps with nutrient uptake, which ensures better recovery and enhanced performance.
